Chimney flashing install | Part 2

[@michaelbeck7799]

We have been engineers and general construction managers for 40 years. We have seen every way to flash incorrectly and they all fail. However, here we have genuine cut-in step flashing! This is the only way to correctly flash a chimney or trim. Very enjoyable to watch flashing done correctly. This should be a training film sent to all roofers in America who would nail their aluminum flashing on the brick and caulk with any tubes of caulk that will fail within a year or two. A genuine thank you for posting this very well done effort.

[@chadvaillancourt]

Than you for your kindness.

[@dumbluck6180]

I just posted above, but have to say I totally agree with you. He did such a good job and the video could literally be a training film.

[@user-sk9hl7si7l]

lol wut,every chimney done with solar seal caulk and proper double hem bent towards chimney will outlast shingles. engineer and manager means you havent done 300 chimneys like i did with my own hands and theoretical knowledge is not always works in actual field work

[@jusnielful]

Would it work if you put the ice and weather shield right to the chimeny and then put roofing cement to cover it?

[@user-sk9hl7si7l]

@@jusnielful just cement along the perimeter can make it last a while,no need for ice water

Hi Chad, Thank you for the videos, you did an absolutely brilliant job, your attention to detail and narration was very well explained throughout. I am pretty sure there will be no problems with this job and your clients delighted with the finished job. I live in Yorkshire, England, and last year had a roof replacement, the roofer welded the Lead flashing as you described, and he also was very conscientious regarding his work ethic and the visual aspect of vertical lines etc. Well done once again.

Super clean install. Great 2 part video to learn from. I have a lead flashing repair to do and this taught me a lot. Pro tip: Once you the last ridge cap shingle is on and the silicone is wet. Rub 2 shingles or caps together over the silicone so the granules fall into the silicone so you don't see the nail heads. Another option is to put silicone/tar/roofing cement all over the last ridge cap and wet set another one over the top of it so you don't have to worry about nail heads.

[@chadvaillancourt]

Thanks, I’m glad you learned something from this. Great idea with the granules. I know they sell containers of granules but I never thought to grab some from the shingles I had. Almost all roofers here don’t cover any exposed nails with anything anymore. Sad really.

[@jpcarpentry4199]

Smart, I'm doing this on my next roofing job!

[@dmech5135]

The reason why the previous repairs failed is because this requires a lot of work, skill, patience and pride in your work. Unfortunately, those qualities have been lost today. Great work!

Wow!! I do chimney work every day in Baltimore city Maryland. I love your technique. Although we don't use lead much. Mainly copper. And even aluminum. This is absolutely the correct way to do this!!

Thanks! You’re totally right, people usually have no idea the time and effort that goes into a job.

I live in hill billy USA. When the roofer talked to me about flashing the chimney following a derecho, he said most people just have it packed wiith roofing cement, but I opted to have it flashed by their sub contractor for $250. The roofer did the lower flashing. The flashing guy used metal, not lead. He didn't step flash but just has it running at angle parallel to the roof line. I had to have him come out two more times to fix it from leaking. He said he cut a groove before installing it. I guess he did. My chimney is well down from the ridge in the middle of the roof. At the time, I didn't know how to build a saddle or cricket and the house didn't have one. My guess is the chimney sat on the ridge back when it was built in 1923, but the deadliest tornado to hit the USA decimated this town in 1925, and it appears they changed the orientation of the ridge from front to back to side to side resulting in the poor placement. Anyway, long story. You do great work.

[@jamescrast6351]

As a retired contractor of 42 years..I can tell you that Through The Roof Caulk is one of the best products for sealing most anything through the roof..It Bonds to almost any materials and it does not dry and shrink like traditional silicone and crack away or pull away from material..Its almost like an adhesive as well as expandable caulk..You are very thorough and looks great..

[@dumbluck6180]

What a nice job! It looks really good too. Good explanations on why you do each step. I do handyman work, and nearly every house I enter has botched work. It blows my mind how much bad work I see. In Part 1 you showed layer upon layer of messy repair attempts that failed. Those hack jobs are fine in an emergency like during a storm when you're just stemming the tide until you can do a proper repair. Very much admire your skill and methodical work. I'm originally from MA and your accent sounds familiar! My 70 year old house in OR has the original heavy galvanized steel step flashing. I re-roofed 27 years ago, and just lifted it up like you said. It could probably go another 20 years, but I'm going to replace it with lead the way you did.

[@chadvaillancourt]

[@fishstick617]

This is the quality craftsmanship I try to achieve on a daily basis. I'm a mason for a chimney company just up 495 and there always rushing me 😆.. I actually stumbled on your channel because I'm a self taught and I sometimes use KZbin sharpen my skills . I also have the same thoughts on caulking those joints 👍 I use a geocel caulking myself.

[@chadvaillancourt]

I’m glad to hear it! KZbin is a great resource no matter the skill level. Everyone has a different way and lots can be learned if people are willing to share. I used the geocel proflex for years but I had to stop because of the cardboard tube. It’s a good product.

[@williamcope2652]

We’re having problems with a smaller chimney that used to be for a oil burn furnace but now simply acts as a stack for the vent and exhaust for the gas forced air furnace. The roof shingles were replaced two years ago and now we’re getting leaking in the basement that comes down the chimney sides. I had to laugh at your comment when you said that roofers and chimney guys don’t do each other’s jobs because my roofer won’t touch it with a 10 foot pole so I’m gonna have to hire a professional like you to do mine And I’ve got a place in mind. Thank you for showing us how the real pros do it. Good luck, live long and prosper.!

[@chadvaillancourt]

Yeah, it’s a tough thing. Your roofer likely put enough silicone to make it not leak for a couple years, now his work is showing through. Thank you!

[@darrenkoeppen6137]

Wow, it was amazing watching the expertise and passion in your work. Years ago I had to research how to do this properly so I could go after the roofers who did my house. They did my entire roof and left me two leaky chimneys. They ended up step flashing both which resolved the leaks...... but originally just cut and caulked a single piece of aluminum in.

[@chadvaillancourt]

Thank you.

[@master_Blaster91]

We use lead plugs to keep the lead in before siliconing little strips of lead rolled up and pressed into the joint so that it's tight and the lead doesn't move 👍👍 but really like how you do it as I haven't seen many people using lead over your way it's great to see

[@Zakflix]

wow, after watching your videos on this chimney helps me realize all of what I thought I knew about very basic roofing and chimney 101, ..is nothing what I thought it was. I don't do that type of work but am needing chimney and dormer leak repair and am tired of band-aid odd job work repair that never works.. and my roof is dangerous to get on

[@blakem9666]

The amount of time and care taken for this job was amazing. I'm redoing my whole roof and wanted to flash my chimney in a similar way but finding lead flashing and the sheer cost of copper just doesn't make sense unfortunately. Still hard to find some of these specialized materials here in the Midwest without paying an arm and a leg.

[@chadvaillancourt]

Thanks! Lead is available at all masonry outlets and hardware stores here, even Lowes and Home Depot have it. It costs about $140-150 per roll now, although I have one supplier that will sell for $110 per roll.

[@markharmon4963]

If you know of another system that works then it would be interesting to hear about it. Otherwise how can you afford not to do it this way? I am not trying to be a jerk.

[@randyhill2509]

Damn fine job!! Glade to see someone take pride in there work wish you could fix mine !

[@bobbarker9986]

Great workmanship! I've been roofing for 45 years and haven't seen workmanship like this. Especially scribing the vertical lines to get a nice plumb look! Only one little nit pick, the nails in the shingle at the bottom left corner (1:02:22) are too close to the flashing and being that the flashing has a slight slant to it away from the fireplace the water is going to head toward those nails. Will it ever leak? Probably not, but after all that fantastic work it's the weakest point. I also like to leave about a 3/8" space between the edge of the shingle and the vertical bend in the shingle to allow a space for the water to run down. The water can still run under slightly but it helps with the water flow especially if the chimney is lower on the roof where there is more water accumulation. Thanks for the detailed workmanship. Nice to know that there are still quality workmanship being done!

[@chadvaillancourt]

Great catch with the nail! I’ll have to do better next time. Thank you for pointing it out and thanks for your comment. Very observant!

[@jasonmurray9291]

Chad, your craftsmanship is top notch. I recently had a roof replaced and 5 days later heavy snow and then windy rain. It turns out I now have water infiltration around my chimney which is what brought me to KZbin looking for an answer. The roofer claims the flashing is the responsibility of a mason even though the estimate included new step flashing (didn't happen). Their answer was they tucked the new lead under the old. I had a mason friend take a look at the chimney because the roofer claims the pointing is the issue. Mason and I went up on the roof and find lots of silicone around one corner of the chimney. The question I have for you is because my chimney is about a foot off the peak how are the flashing and shingles supposed to tie into each other? Basically there's an area where snow and water can sit and is sitting, the silicone is spongy and has a pool of water sitting in it. Granted I'm in New England and did have a heavy snow followed two days later by heavy winds and rain but water infiltration is not ideal period especially when it never happened with the old roof.

[@chadvaillancourt]

If it didn't leak prior to the new roof, then it's the roofers responsibility to fix. Water should not be ponding behind the chimney. That's on the roofer to get water to pitch out of that area.

[@lauraalmasan3930]

Outstanding job! That flashing looks professional

[@chadvaillancourt]

Thank you!

[@Deep_Divers]

Great info! I wonder if the primers they make like perm a barrier or Henry would help with the membrane sticking. The big issue with those might be the time to set up. Your solution is probably faster and more efficient though. Keep up the good work Chad!

[@mikereckert2705]

Chad, I have to say that I am very happy to see pride in craftsmanship! I hope you share your ability and attention to detail with someone so it's not lost. I'm watching these videos due to the fact that we have a newer roof ands it's leaking into the fireplace. I have a tarp over the cap to see if it's coming from there, but it's still coming in. Which i assume leaves the flashing, which looked a bit like this one in the beginning. Mine however is on an exterior wall and recessed into the roof with a 5-12 pitch. The chimney is 3 to 4 ft wide, and the ridge side is just flat to the back of the chimney. Shouldn't that have a gable built to the back of it, to divert the water away? It's probably 14' of water hitting on that side. You can see were the previous flashing was stepped down the sides, like you did the lead, and the caulking was just left, and the new flashing matches the slope and is caulked in. I don't suppose you are local to NC? Either way amazing work!

[@chadvaillancourt]

Anything over 30" wide; parallel with the ridge, really should have a cricket or something to help shed the water. Thanks for your kind words!

Our house is thirty years old and the roof needed replacement because of a hurricane. The leaking is bad whenever we have a heavy rain. Nothing was done to replace the flashing or to fix mortar and brick erosions. We have a lack of available roofers because hurricane Ian caused major damages to Florida.

Chad - Thanks for the great detailed videos on this flashing technique. On both of your repair videos the chimney is at the ridge. My chimney is at the bottom eave/gutter end. It is about 20" wide so no need for a cricket. But how would you flash the back side of a chimney like this? Would you get a 30"x30 square piece to go up the chimney and up the roof in one piece? I would be concerned any piece on a 4/12 pitch roof would tear trying to make the bend on the corner from the back to the side. Thanks for any advice.

Just ask them to make sure the mortar is all sealed up underneath the new flashing. Definitely tell them you want ice and water shield around the chimney (I prefer the Grace brand) with a 3” lap onto the chimney.

Hi it all looks very neat and I am sure you know what you are doing but if the chimney was in the uk it would not solve the problem what you are doing is probably the best that can be done without rebuilding the chimney and installing a lead tray in fact a chimney like the one you are working on would require two lead trays the first 3 courses above the bottom or at the level you have put your cover flashing and the second just above the ridge capping

The KZbin algorithm is ridiculous, you could search the exact title and something else irrelevant would pop up first because it has more views and they have more subscribers. I hope you find the videos helpful.

[@tittyskillet3413]

Wow. That looks so good. So how much did that 3 day job cost?

[@rockyrowlands3652]

Excellent explanation and I enjoyed your video. I’m not a roofer or a flasher 😅, but I’m an ex paratrooper but do have fear of heights. I must admit I was nervous of seeing you work at height but using no safety scaffolding. You clearly know what your doing but it only takes one mis step or accident….just my thought.

[@chadvaillancourt]

Than you for your service and for your kindness. I would never jump out of a plane, you’re nuts! 😂

[@albluthe410]

Great work and video

[@chadvaillancourt]

Thank you!

[@fintan3563]

Can that old lead be recycled? Asking for a friend! 😄😄😄

[@chrislnflorida5192]

U don't cut the Verticle Cut to tuck your Flashing into the Brick? I've always laid my Shingles Over the Flashing, the Tar under the Ends to seal and stick. Nice Clean job 👍👍 I still not sure about Not Notching the Verticle ends of your Flashing. Blowing rain could get behind that area unless u Caulked under the Edge.

Outstanding

[@dannybrouillette9462]

This might be an excellent job where ever you are located. This simply would never work in South Louisana. Some unique technics. Good for you.

[@chadvaillancourt]

Would it work in Northern Louisiana?

[@skills7071]

How do I get you to my house? That is amazing work by someone who takes pride in what they do. I'm serious, How do I contact you?

[@nlimchua]

outstanding! shared wisdom is best.

[@ednoname4121]

Great work,

[@chadvaillancourt]

Thanks!

[@johndoe-lz8ru]

Nice work you do. Surprised you didn't put some shingle grit over wet silicone on ridge shingle nails heads so they are hidden from view. Really good job though,I'm just Handyman but i can see what craftsmanship is.

[@chadvaillancourt]

Thank you. I guess I cannot remember, I thought I did put granules over the silicone, sometimes I do this although there is no real benefit. The silicone holds up to UV degradation without being covered, tar does not.

[@johnwayne2103]

What a gorgeous job, I bet that cost the homeowner as much as they paid putting on a new roof.

[@chadvaillancourt]

Thank you.

[@Erica-os2mp]

Nice!!

[@MrTeekay2009]

Overall a great job, best I've seen. However, silicone will not last as long as polyurethane roofing chauk, I've cut open 40 yr old polyurethane chauk and it was like new inside and still stuck to everything, silicone will never last that long on the brick. Why would you fix the flashing and not the cap which is likely the cause of the leak? In my book, not fixing the cap is as bad as using wax paper as an underlayment that you complained about. If you fix it, fix it 100%. If the owner says no to the cap, don't bother with the flashing. You could have added a lead or metal cap with a 2" overhang and then put the existing stainless cap back on thereby adding a drip edge keeping the bricks drier.

[@chadvaillancourt]

I told the homeowners to fix the top, they didn’t want to spend the money. They asked me just to do the flashing. It’s always an option down the road.

[@chadvaillancourt]

Everything I’ve ever seen or read suggests that silicone is far superior to polyurethane as it isn’t subject to UV degradation. The new silicone is so good compared to the stuff 20 years ago. I’m very confident in using it.

[@MrTeekay2009]

@@chadvaillancourt Yes, it does UV degrade, but only the top 1 to 2000 of an inch. Once that oxide forms, it stops degrading. That is why all skylight manufacturers use it and not silicone. Polyurethane might look bad on the top, but inside it's like new, I've seen it on skylight glass I've had to replace and on other surfaces. Plus it will adhere to damp surfaces and stick forever, while silicone will not. It's nasty to work with, so you need acetone to clean up after, but it will outlast silicone by far. I've seen those articles about cracking when cold and sagging when hot, I've never seen that in over 40 years of using it on skylights and flashing. Never gets brittle in the cold or sags in the heat. At least the quality products I have used. Maybe cheap stuff will. But that can be said of cheap silicone as well.

[@chadvaillancourt]

Interesting, I’ll have to look more into this. Do you have a specific brand you like?

[@studleyjb3172]

​​@@chadvaillancourt How do you warranty your work if there is a known problem ( the cap) when you are done? Considering what they are likely paying you to do this, the cap seems a strange place to cheap out.

[@xtcguy29]

So chimney flashing done by different people not the roofer? So when you habe a problem who do you call to repair chimney flashing? I though roofer does that kinda job?

[@chadvaillancourt]

The flashing has always been installed by the mason while building the chimney, then the roofer comes later and ties in the roof. Now, the roofers insist on installing new flashing every time a new roof is installed because it's an upsell. That's usually when it starts leaking. They hire the least skilled people and have them go fast. The skill level in roofing is probably at an all-time low. Profits are at an all-time high.
