Hi Dan, great video thank you so much for your detailed video. The only OSI product I could find was the quad max sealant.

Hello Dan, super informative! we just re-do our tiles roof there is no leak, just due to over 34 years, underlayment may be deteriorated be proactive instead of reactive. besides replaced more than few dry rod Shiplap and one water damaged fascia board. roofer installed 3 O'Hagin attic vents, later I found out those vents were make for shingle roof application, roofer said the base is the same. your video is absolutely great help as I noticed there are many broken lower corner tiles all at the left hand bottom. I have sealed few of those tiles, after seeing your video knowing I had over sealed the channels. Will have to go up to the roof broken off part of the sealant. appreciated the detail information.

[@Garciasroofing]

Dan , you are a perfect example of the old school , 30 Lbs. felt underlayment and nails, when well installed , you don't need the expensive and overpriced labor or many so called roofers using peel and stick underlayment . next time try to find the matching tiles, usually the manufacturer makes the new version of the old tiles like this. Good repair ! I would definitely have you on my roof !! Eric.

[@stevetai5647]

Hi Dan, could you tell me what is the best tile glue where one of my tile is cracked vertically? thanks in advance.

[@MrThedocholiday]

I use OSI Quad construction sealer adhesive. It’s available on Amazon & comes in various colors. It will only last a couple years exposed to the weather, so you may want to put a sheetmetal flashing over it & paint the metal to match your tile. Most of the time when I do these repair for others, the customer only wants a couple year warranty so I just do whatever they tell me to do, but you may want to go the extra mile on your own roof & flash over the caulking as I mentioned.

[@Nothin9Specific]

Im confused Mr Dan . You said not to use the plastic cap nails, but if your tiles aren’t broken is water still going to get down there ?

[@MrThedocholiday]

Good question. So here’s my answer. What’s wrong with plastic cap nails? There are 3 main reasons why plastic cap nails are bad & it’s not mainly because of water. 1. Plastic cap nails do not & cannot clamp the felt down to the roof deck like metal cap nails - like the felt needs clamped/held down under any extreme conditions. And all tile roofs are extreme conditions. 2. As soon as plastic cap nails are installed, they begin stressing the felt at the point where the cap nail itself penetrates through the felt, because the small metal nail head applies pressure to the felt but the larger plastic cap doesn’t provide nearly as much clamping pressure as the plastic cap metal nail head itself does, because the flimsy plastic flexes & retreats from the surface of the felt while the nail itself does not. For this reason the plastic doesn’t have the rigidity to hold the felt evenly around the perimeter of the plastic cap like the metal nail going through the plastic cap does, so the plastic cap is loose compared to the metal nail & immediately begins stressing the felt in this way the minute it is installed. Because it does so the hole in the felt from the plastic cap nails begin to enlarge very quickly compared to metal cap nails over time. 3. In addition to these immediate plastic cap flaws, the heat & humility under the tile cause the plastic to deteriorate at an accelerated rate that is not comparable to the rate of deterioration of any of the other roofing materials being used in the same roofing application. Plastic cap nails should have never been approved for tile roofs & the fact that they have been is proof that idiots often make rules based on speculation & theory without the slightest real experience & proof that their theories will work in the real world over time. I hope that helps relive some of the confusion regarding plastic cap nail flaws compared to metal cap nail strengths. Thanks for watching! -Dan-

[@darcymunro8930]

[@nathanielramos3998]

Great videos! Those galvanized nails that hold the Felp paper. How do you prevent leaking through them? Same question for the nails that hold the tile to the roof. Thank you in advance!

[@MrThedocholiday]

The galvanized felt nails are waterproof in their design, provided they’re installed properly & not exposed to excessive water volume coming through the tiles. The felt nail shank seals as it goes through the tar-saturated felt paper. The large felt nail metal cap helps protect the nail shank seal as the shank goes through the felt. The tile nail shank also seals as it penetrates through the tar-saturated felt paper but because of its much smaller head, it’s not as waterproof & it’s much better protected from large volumes of water intrusion through the tile by the manufacturer’s recommend maximum tile exposure measurement of 13.5” at most. Some cement tile brands have allowed for a 14” weather exposure, but my 36 years of on the roof experience says 13.5” is the real maximum weather exposure if you want to protect your felt paper well & keep those felt nails waterproof also.

What other option to puncture the tube than the nail? (Which I don’t have). Thanks for the great video Dan! May God continue to richly bless you 🙏🏾✝️

[@MrThedocholiday]

The only three options where I worked according to code were nails, glue or battens that are nailed to roof deck to hang the tiles on. In every case roof deck must be covered with at least 30lb felt paper before tiles get installed.

[@MrThedocholiday]

I carried a cement drill bit with me & a cordless drill whenever I works on cement tiles. I can’t over stress the importance of having the right tools with me to handle the inevitable problems that arise on most jobs... Like bad cement tiles that the factory neglected to pierce the nail holes properly in.

Bob again, thanks for your time to answer my question.

[@eliace5023]

Hi Dan not sure if I missed it, but what brand are you using for this repair?

[@MrThedocholiday]

If you’re referring to sealant, I currently use OSI Quad from a caulking gun. At the time of the video I likely used Rainbuster 850, but I think that’s discontinued now. Both sealants have similar properties… they stay flexible, they adhere to most materials, they’re waterproof, removable with a scraper or razor knife, fairly UV resistant, inexpensive & come in different colors for topical applications.

[@Ziggy_v2]

Best how to roof repair video ever 👍

[@gordonpotts753]

That was nice. Very professional

[@stevenjensen2649]

Dan! What kind of sealant did you use for cracked roof tiles? Brand? How about walking on the roof tile? Crawling on the top roof? 😮

[@MrThedocholiday]

I now use OSI Quad. It’s the only comparable alternative where I live.

[@stevenjensen2649]

Okay, Thanks 👍

[@MrThedocholiday]

Now for walking on the roof… It’s most likely that whatever chipped, cracked or broken tiles you see on your roof were cracked or broken by someone walking or standing on them. So learning to walk on them with your feet perpendicular to water flow & across at least two crowns at a time, to better distribute your weight across more support, rather than one crown & less support, is key. Also, if you walk across the lower 4” of each course of tile where they overlap the course below-the exception to this rule is the very first course at the dripedge which is unsupported by tiles below it-you have much more support for your weight there than you have in the middle of the tiles where they are only one layer thick. Also, if you have to stand still on the tile, try to distribute your weight evenly on both feet at a time, again for obvious reasons. Otherwise it’s best to keep moving across the tiles whenever you’re weight is shifting on one foot at a time as you’re walking. Lastly, the more you keep your weight distributed on both of your feet at a time, the less chance you have of breaking tiles under one foot or the other, for obvious reasons… your weight is most readily distributed across more surface area this way. Also, tile roofs are the one place where you want to always avoid stepping on cracks unless you’re trying to break tiles. Add all these tips together & you will always fair much better walking on any tile.

[@Steve211Ucdhihifvshi]

interesting that you guys use felt, here in queensland australia of the last 3 houses ive had that had tiles none of them had and sagging (like foil material that goes where your felt goes) im no roofer and it rains a hell of a lot here in qld so i wonder why we dont have felt?

[@daultonruff2281]

What kind of tacks are those holding the felt paper? Do you put tar, or sealing product on the nails and the seams? Thanks for your words about the galvanized nails, and comments about the plastic ones.

[@MrThedocholiday]

Normally I use round 1” metal felt nails. Others use all different kinds of felt nails so if you’re referring to the ones I used on the new felt repairs, then yes… metal cap nails or felt nails. No sealant needed on any of the seams because felt is overlapped on sides & lapped under the course above & over the course below with at least a 2” lap. Everything is to code the way I do it in the local municipality where I worked. Check your local codes if there’s any concern about how to install felt & tile in your area.

[@daultonruff2281]

@@MrThedocholiday Thank you. I will shortly be up on my roof tracking several leaking spots so I'm watching a few of these videos. I will look for these galvanized nails to use for my repairs. Other videos show all seams sealed with that black tar product, but I suppose it depends on the area. Being paranoid I will be using it also. Thank you for your quick reply.

@@MrThedocholiday Makes perfect sense. Thank you for taking the time to reply. Temps here around 105 so I'll use the time until it cools off a bit to research another problem. I don't see a video about repair of the Ridge, and what to use to put under the tiles. I only see one other video and it's not descriptive for my problem. My roof is primarily leaking at the top, I think. I have a tin foil pan flattened in one spot up there, and it worked, but I need to do the whole ridge. Ranch style house about 2200sq ft.

@@MrThedocholiday Another question after watching a video about the ridge. They are using a lot of mortar. There is none on my roof. They use the word "underlayment" that I can see tacked to the ridge 2x6. Is that felt or is there a special product for this? Thank you for your time.

[@bkp-pq1fl]

Hi Dan, For a flat concrete tile roof, when two sides meet at 90 degrees, what is the recommended gap it needs to have so it will flush out the dirt in between the valleys? My original roof valley is less than 1/2 inch, and it is gathering leaves and dirt and is hard to clean out. Thanks for your input. Regards,

[@MrThedocholiday]

The top corner of each of the smaller ‘cut’ valley tiles which point up slope needs to be broken off or cut off, so that regardless of what the valley tile gap is, when debris gather in the valley, those ‘cut’ tiles don’t divert water across the roof out of the valley, under the tiles, onto the felt paper. Make sure whoever does this doesn’t leave the cut or broken corners in the valleys. In addition, I like the gap to be at least an inch on each side of the valley. Of course nobody breaks off or cuts off the top corner of all the smaller ‘cut’ valley tiles upon initial installation, so eventually all flat tile valleys without this installation method will leak for this reason. Valley metal companies have attempted to compensate for this ‘flat tile’ oversight by adding ridges to their valley metal, but it only requires a little debris to build up behind these top-pointed triangle shaped small ‘cut’ valley tiles for the rushing water to flow sideways right over the valley metal ridges, under the tiles, off the metal, across the roof & onto the felt paper. Without the top pointed corners of the smaller ‘cut’ valley tiles removed, you’re gonna need at least a 3” gap on each side of the valley to prevent water flowing out of the valley, across your roof, under the tiles. Because that’s how wide the river of water flows down a valley in a decent downpour. Making a total of at least a 6” gap. You do realize how terrible a 6” valley tile gap looks from the ground aesthetically, right? There is no other solution that I’ve found around this ‘flat’ valley tile issue over the last 36 years. And I have done literally thousands of roof repairs personally from my toolbag of tricks. Don’t let any blowhards tell you otherwise on this issue. There are a lot of blowhard roofers out there, so beware. My brother is re-roofing his flat tile roof himself 2600 miles away because of this very reason & he is pulling his hair out because I cannot repair it for him in person at this time. This flat tile valley issue is a nightmare to deal with. I’ve even watched blowhard arrogant expert roofers on KZbin come in & reroof valleys for customers only to have them charge to do it again every 10-15 years. It’s basic physics. Do you know how hard it is to convince so-called experienced roofers of something they don’t already know? They would rather just keep recharging the customer to do it again, instead of learning a new method to solve this problem permanently.. If you like, I can draw diagrams of the issue & solution for you & email it back to you for a fee. My email is [e-mail]. I’ll give you my cell number at that time to discuss any questions you might also have. At least you can do this yourself or have another roofer do it for you. Knowledge is power…

[@bigt8699]

Great video, can I use sealant for small chips/holes and if so is it a special sealant for the tiles or any sealant? Cheers

[@MrThedocholiday]

Yes, but chips normally happen at corners where water flows down the side lap channels of the tiles. Take extreme care here not to block the side lap water channels with adhesive just to glue chips back in which are mainly for looks only to find later that you’ve now created leaks that weren’t previously present. I’ve seen this hundreds of times.

I wish I was closer. Working for customers who appreciate quality has always kept me with plenty of work over the years. I suppose if more craftsmen aimed at quality instead of quantity, I’d have to compete a lot harder for the work. But to each his own. I can offer a little advice on screening contractors though… 1. Look to hire tradesmen who value their reputation by keeping their license current with local authorities & have little or no complaints filed against them with the local licensing authorities. 2. Check local review listings to see what the local community says about someone’s labor before you even bother calling them. 3. Lastly, negotiate to have a supervisor on the job daily while work is being done, or at least check in to inspect the work each day before their laborers move forward on the work. You’ll save yourself countless headaches by doing just these three things. Thanks for your kind words. Thanks also for watching & Godspeed to you & yours!

Great information awesome video!! What is the name of the glue/sealant caulking that you use and trust?

[@MrThedocholiday]

Polymer… any polymer will do. Problem is most products don’t tell you what’s in the caulking on the label. So you have to speculate based on the name. For instance: OSI Quad is a quad polymer. In the past I’ve used copolymer & tripolymer & both have been sufficient & fairly durable.

[@randalllegallais9222]

Dan Very informative video. We have a Marley Concrete Tile Roof about 33 years old and the lead valleys have developed some splits and 3 leaks have occurred. We live in Niagara Falls Ontario and wondered if you have some suggestions on what is necessary to repair this issue and on a qualified roofing contractor we can hire to do the necessary repairs. We have about 200 extra tiles on hand if any need replacing. Thanks so much

[@MrThedocholiday]

I’ll respond with a full answer soon.

[@MrThedocholiday]

So, I’m not sure what the codes are for roofing in Niagara Falls, so you may want to check into that first. Secondly, I’ve never worked with lead valleys but I imagine the splits could be welded up or re-soldiered. My only concerns would be whether or not the membrane under the valleys is water tight or not & why the lead valleys split in the first place. Other things under the valleys may need addressed by a complete roof restoration in your case. I wouldn’t know without inspecting it myself, so you’re gonna have to determine that for yourself. Now, regarding finding a good contractor... I don’t trust anyone to do good work today unless I already know their work. But I can offer some advice in finding a quality roofing craftsman or company. 1. Make sure they are licensed & do a background check on their license. Companies that maintain their licenses well typically do better work to guard their license status with local authorities. 2. Check local online reviews of various companies in your area to get an idea what the public thinks about their work & whether they stand behind their work or not. 3. Once you find one or two possible contractors who pass the test of the first two steps, when you contact them, negotiate to have a supervisor check the work being done on your roof daily, before you agree to hire them, to make sure their roofers will do quality work for you. If a supervisor’s job is on the line your roof will likely get done well, but without supervision roofers are a dime a dozen & can just skip on down the road to the next roofing employer if their work fails. If the company is not willing to negotiate for a supervisor to check the work once a day, I’d respectfully pass them by & move on until someone worth their salt will agree to be more reasonable & professional. Hope that helps. Thanks for watching.

[@woodpeckerroofing93]

& 31 min you acknowledged why the pattern should be 1/2&1/2..... the tiles will sit better break less corners if walking on it. I have lots of experience with this tile, this is hung on skip sheathing hanging on rafters here with no tar paper protection. One mistake water is instantly in a house. Broken tiles = emergency mass water in homes. You can get semi trucks of these tiles here with planning from roof replacements because of this issue with their lacking decking & underlayment. Take home tiles & trims whatever you need then upgrade your customers roofs with full tiles everywhere needed new underlayment then Pressure wash their roof & reseal it with color in a concrete sealer. Reduce the water it exorbs during winter getting heavy. I have witnessed max saturation end of wet winter and a solid tile no cracks no holes leaking it was just wet concrete dripping from back side in attic looking at it. Because i could not locate a break in the rain. Cant just start picking up tiles in that situation. I learned to convert these roofs to solid deck, with out fully unloading the roof. My finished product was a washed roof and restored with sealer to customers color spec with other contractors just repair tiles washed paint with out fixing the decking issue. Or most contractors are replacing them to shingles. If you work with supply houses they can work with local and unloading the tile roofs with conveyor back to shop for your semi delivery.

[@benedmund7456]

Great video. My leak occurred at the bottom of the roof by what I call the "bird stop" It almost created a dam of debris over time and the felt paper fell apart and the leak showed up at a window about a foot below.. While it was raining I cut a section of the bird stop out and the water leak around the window below stopped. The leak was really close to a roof valley and I think debris was cause a back up so removing the debris got the water flowing again. I have to do a good repair after the rain stops. Any advise on the bird stop I need to replace? I am guessing since it is at the bottom I put it on right after the felt paper. Thank you!! Sorry for the long comment.

[@MrThedocholiday]

Ben Edmund depending on how long a piece of birdstop you need, you could make a piece & paint it. Otherwise you’ll need to just pull from what roofing suppliers have in stock that might work for your profile of tile.

[@jeremyfennelly9637]

Hi Duster Dan, I hope your consulting is going well. Just watched our video. I have the same roof tile you are working on. After a bad experience with a roof leak last year, I feel much more empowered to take control of my own destiny. Do you have any videos that show how to seal around solar panel footings? That would be super helpful.

[@MrThedocholiday]

Jeremy Fennelly No, I don't have any videos on solar panels & roofing. There are a lot of different kinds of roofing that integrate with solar panels & each type seals the panels a little differently. With tile you need to anchor the solar panel feet to the roof sheathing - preferably right on the rafters. Secondly, you need to install felt around the feet & either seal the felt to the feet with sealant or flash the feet, so that either way they are waterproof at the felt/feet transition. Thirdly, you need to install the tiles around the solar panel feet & either flash the feet again with flashings at the tiles or seal the tile/feet transition with sealant. Keep in mind that if you seal the tile to the feet instead of flashing the feet as they go through the tiles, then you will have to reseal all the places where the feet go through the tiles every few years to keep them water tight. Does that answer your question?

[@jeremyfennelly9637]

This makes perfect sense. Thank you for taking the time to respond. I value a little more time on the repair and to prevent interim upkeep so I'll go with the flashing. I think I should be able to find examples of how to flash around the feet and where the legs pierce the tiles so I'm not re-inventing the wheel.

[@johnal4560]

what is the name of glue that you use and where u get that metal that you used does it come in that shape plz thx

[@MrThedocholiday]

john Al OSI Quad from Lowe’s is what I currently use. It is similar to what I used in this video. And no, the sheet metal doesn’t come in that shape. I had to bend it into the profile of the tile. Sheet metal in smaller pieces is available just about everywhere. Thanks for watching.

[@marlon111ish]

Thanks for your effort. I'm in Indonesia at the moment, and they have no felt, no ply ( just tiles ). The tiles are leaking evreywhere and the ceiling panels inside are rotted everywhere. 20yr old place. Looking up through the manhole inside , i can see daylight in a lot of places. Without replacing the entire roof, and laying down ply and felt, i'm assuming i will have to seal what i can from the underside first, then seal the outside? or vice-versa, but the daylight will be harder to spot. Then water blast the tiles and prime and paint? It's hard to source things here in borneo, and i hope they have 1,344 tubes of quality sealant. VERY dodgy building here. Am i on the right track?

[@MrThedocholiday]

Sunnie Winters basically, yes... I always like sealing out water on the topside only. Because anytime you seal water from the underside you risk trapping the water after it has already penetrated the topside. That can cause more trouble that likely have to fix later, but in your case I’d seal both topside & underside, being mindful NOT to trap water doing so. You want to keep all the water out of the roofing as well as out of the building. But yes you’re on your He right track. Godspeed & good luck.

[@robertseeley2001]

This is Pam's husband Bob. I noticed in the video that the caps holding the felt paper were not covered with a roof coating to help seal any nail holes , would that be a good idea to do that or is it not necessary? By the way, excellent video and very informative. Well done !!!

[@MrThedocholiday]

The metal cap nails for the felt are watertight just the way they are, however, they're not intended to remain exposed to the elements indefinitely, but must remain protected by the roof tiles in order to remain watertight over time.

The Underlayment needs installed in a overlapping manner... meaning it must be tucked under the good felt above & over the damaged area below. And yes, nail it in place & replace the tile if you can find a replacement. Good luck.

[@steveruiz5259]

Hi Dan I'm looking for a bendable material that you would use like around a skylight to meet or connect with the tiled roof. A corrugated soft metal that shapes around the S tile ,I've seen them around skylights with S tiles on the roof So when the the water runs off the base of the skylight frame it runs on the shaped metal around the tile making it a smooth water runoff If I knew how to attach a photo I would velux makes a real nice transition kit but you have to buy the whole kit. I just need the bendable portion about twenty feet for water to transfer smoothly from roof to tile,for a project I'm doing . Thanks for any advice

[@MrThedocholiday]

Ultimately the best thing in my opinion is hard galvanized flashing used in concert with mortar at the base of the skylight. The tile would tuck under the flashing & the mortar would go under as well, filling the pan of the tile under the flashing. The key with using mortar here is to leave it slightly recessed under the flashing & sloping outward to help sheet water away. But if hard flashing isn't your choice you could use a thick peel-&-stick roofing, aluminum, copper or even lead - all of which are flexible enough to bend around corners or to conform to the shape of the s tile to make things water tight. Skylight flashing is a real science & you really ought to have someone show you how to do it to get it right regardless of what materials you use. If I have a video on this I'll upload it for you to see.

[@patrickokeeffe6998]

Great video, our tiles are same, we have moss growing between tiles. Would you recommend power hosing to remove moss. Have u also a video on vent tiles for these tiles. Thanks

[@MrThedocholiday]

patrick o keeffe the only issues with washing the tiles down are causing unneccessary water intrusion, breaking tiles & not getting all the moss off or just having to do it again soon. Tile roofs are not made to walk on often without breaking tiles. Aside from that, cleaning the moss out of the sidelap on your tiles could prevent future leaks. I don't recommend cleaning the roof unless you know the side laps in the tiles are blocked & letting water get through the tiles regularly.

[@MrThedocholiday]

patrick o keeffe sorry but I don't have any videos on vent installation for tile roofs. Lord knows I've done enough of them just never made a video about it. You'll want to start by checking with your local roofing supplier for which vent go with which profiles of tiles. Good luck & let me know if you have any other questions

[@Brian-vr1rh]

Hey Dan! Your videos are quite instructional and very informative to say the least. I have some questions about my roof. The cement tiles on my roof are S type and are attached with a kind of cement mortar. Would you reuse this with an adhesive or buy a bag and mix it when needed? I'm wondering why the roofers didn't use a metal channel because with the mortar is seems like the cement creates places for debris to accumulate. I've developed some cracks in the paper and I now have a leak. What are your opinions? Thanks,

[@MrThedocholiday]

This is a long answer so please bear with me. It sounds like you have clay “S” tile rather than cement, because only the trim of cement tiles are attached with cement, whereas the field tiles are not. It would also make more sense that the original installers didn’t use valley metal because metal is more typical with cement tiles whereas clay tile - especially older clay - is often installed over a built-up application of underlayment which is waterproof without metal flashing; at least for a while. These days it’s rare to see any tile without valley metal for the very reason your roof is leaking. All membranes in valleys eventually wear out without valley metal. Anyway, on to your questions... You can do this however you want, but I would repair it with adhesive reattaching the tiles with existing mortar & wherever the mortar is missing, I’d apply new mortar to attach the tiles being reinstalled or replaced. I’d replace all the bad paper wherever it’s breached, tuck the new paper up under the existing good old paper above & overlap old paper down slope wherever it is still good. In essence replacing all the bad paper like it would have been installed if it were being installed long ago with the original paper. I would absolutely make sure all the paper overlap up slope & down slope is tucked & lapped in a watertight manner, so that IF water ever breaches the tile, the paper will keep things watertight regardless. Now, on to the tile... Install broken tiles & reinstall good old tiles (AS IF) there is NO felt paper to protect your roof from leaking. Make sure all your tile overlaps are sufficient to shed water properly in a downpour. Use copper or galvanized metal flashing integrated with the tile wherever higher volumes of water flows in valleys, below valleys, around all vents & ventpipes, in roof to wall areas & around every obstacle on your roof. Fasten all tiles with at least one nail & glue all tiles that cannot be nailed for whatever reason to the other tiles that are nailed. Make sure all rake trim tiles receive two nails even if you have to cut or drill a second hole in them, because rake trim tiles are a safety issue more so than the others. All ridge tiles typically receive one nail to keep in place. Of course, check your local codes & follow all of them exactly & don’t merely take my word for this. Codes vary between jurisdictions & not all areas will be the same as codes where I learned my craft. Always consider all advice based on local codes. You will get a ton of different recommendations from various so-called experts, but what most so-called expert fail to comprehend is that the way they learned may NOT fit the local codes where you are because local codes vary & installation applications vary based on different areas, authorities & climates. I hope that covers the basics for you. Feel free to ask here if you have more questions. Godspeed... Sincerely, Daniel

ib crypto That totally depends on your local codes which are based on certain requirements that are regionally determined by local weather patterns, levels of storm intensities & the type of roof structure. Personally I like to see every other tile nailed to the battens when they are present. The exception for me would be higher pitch roof structures which require every tile nailed to the battens for obvious safety reasons.

[@moonchasestar]

Thanks. You are so helpful.

[@MarkSmith-js2pu]

Dr Dan, you clearly know more what generic repairs are available-here in the Southwest. They don’t know what you know. Roofers for the most part, are not interested in learning these techniques. Roofers want to replace all roofs if they lean a latter on if the insurance company is coming by. They specifically tell the homeowner not to tell that their roofer will be waiting. Usually by the initial conversation I knew that there would be be a roofer, he had preceded me deliberately ,warmed up the insured, made me out to be the bad guy, and did me the” Service” of giving me a prepositioned ladder, which I did not want or Need my ladder was often better than the roofers. I also knew the size of the roof and the weather history on that zip code. The roofer was not a roofer , he was a salesman. Usually he was full of it, but not always. If the facts lined up, insurance paid for the roof, if,facts did not line up, I and my company, were crooks and typical of that mindset. It’s not hard to tell wear and tear to a roof, regardless of what kind of roof it is. I have “walked” 1000’s of roofs that most roofers. Over the years I have learned to consult with honest men that know more than me, and then I differ to me.

[@RyanBurisch]

Hi. Thanks for the time you take to make these videos. May I ask, what actually causes concrete tiles to crack? Thanks

[@Btu555]

would it make sense to move all the broken tiles up to the top or near the top since less water volume?

[@MrThedocholiday]

Not a bad theory, but here’s the problem with that… a good amount of water will still get through those tiles unless they’re sealed & the water will run under the entire length of the roof until it reaches the dripedge. I’ve seen even a small amount of water do extensive damage when the roofing leaks every time. So imagine now a broken tile near the dripedge… If water gets through that, even more water than above, then it only ruins the felt from the entry poin to the dripedge. So the question I’d ask, is whether or not more water does more damage than less water, if each area gets wet every time? Does the felt get damaged more from the volume of water or because of the number of times it gets exposed to water, however much water that is? I think the number of times the underlayment gets wet is more damaging than the actual amount of water that gets on the felt. I’m not referring to just a few drops. I’m talking flow volume, not just moisture. So since broken tiles will let water in every time it rains, it doesn’t matter as much where they’re located. I’d be more concerned with the length of the damage area being longer from tiles at the top than I would tiles near the bottom. Every leak is different & my perspective is somewhat subjective, but it’s also based on 35 years of experience repairing literally thousands of leaks.

[@Btu555]

@@MrThedocholiday Yes, still have to do what you did. I guess there's no perfect solution other than replacing new ones if available. It's less water volume going through it for sure but I can see the disadvantage of moving to the top is that if somehow water gets through it would go through all the way from top down :(
