These videos are wonderful and I’m learning so much about roofing. And your wife is an excellent videographer!

[@kpete9219]

Thank you so much for this video. I bought 1.9 gallons of the product and some cheese cloth. I have a similar problem but no residue of any prior attempts to correct the problem. You and your wife are a great team and it looks like there is much joy working together.

Thanks. I have exact same situation and roof seam. The more I seal it the more it leaks. I shall try your method as it looks correct.

Why didn't you tuck flashing under the upper roof and over the lower roof?

[@garyteague9555]

Exactly, what foolish way to repair this

[@gabebustos338]

I fixed one like that not to long ago. The water was coming from some vents higher up that weren’t sealed. It has transition metal but it was on top of the underlayment so water was running under it. Water finds a way!

[@raypeterson9643]

I watched a bunch of your videos before this one, now I don’t know how much of the information I can trust after hearing you say many times never use silicone on a metal roof. I don’t understand why you used a big silicone patch and seemed like you didn’t get to the root of the problem from higher up.

[@josiahamaze]

This dude just be saying stuff honestly

[@dannybarnhill9834]

The only issue I have is at the joints. That's not 100percent leak proof. Transition flashing is needed. Where the metal laps, he puts sealant under and over joint, but sometimes that will not fix leak water can still penetrate at the joint above where he sealed. You'd have to seal the entire overlap to be certain. Especially with ice. Transition flashing period. I understand they're trying to sell products. This product may be excellent, but not in this area.

[@MexicanGirl]

Sweetheart very nice information and nice video love you

[@davidstobie5373]

Why did you tek screw into the centre of the pans? I thought you should screw into the tops of the ridge, or inside the pans but next to the overlap ridge as this will hold down the cap edge of the overlapping sheet much more firmly. What you haven't pointed out is this roof is incorrectly overlapped, with the underlap side of the sheets being put on the top of the overlap side. The sidelap between sheets of roofing is designed to have a capillary cavity . (The underside edges have a 10mm flat section at the sheet edge, the overlap edges have a tighter curve and a higher sheet edge) The manufacturer states do not block these cavities because moisture entering the side lap may not be able to drain unimpeded down the roof slope. The video shows from about the 10 minute mark the sealing of the underside of the ridge. Good possibility of blocking the ridge cavity and sending water in just above the top sealant line. A thin line of sealant 50mm above Seal, spiralling down from the top of the ridge downslope to the pan, and a small v cut above this to allow an exit of capillary moisture above the joint, will fix these upslope side lap joints. Extending that lower roof still applies. so that you are relying on the natural flow of water instead of relying on the blocking with sealant. Lastly what happens when you need electrical access?

[@Cris-ih3jx]

✋you're the best

[@FlatRoofDoctor]

thanks

[@davidquinn1041]

Where do you get the "fleece tape" used in the video?

[@davidstobie5373]

You have stuck the overlapping ridges together on the sloping roof. There is normally an anti capillary gap on these side laps and normally they should be able to run out at the end of the sheets onto the flat roof section. (there is a designed in smaller radius on the last overlap of a sheet). Blocking this capillary gap invites moisture to cross around the ridge into the inside, before it gets down to the flat roof section. Keep it open and extend the lower roof with turned up pans.

[@hisreign4me]

I have a question: I have a galvanized roof that is about 37 years old. It doesn’t leak, but the galvanize coating is wearing off and it’s starting to rust. For the last few years I have been using rust converter to try and stop the rust, and then use spray can cold galvanize compound to cover the rust. What do you suggest for a problem like this? The rust is unsightly and I don’t want it to rust all the way through the roof. It’s pretty large areas scattered about. It’s a silver roof with white trim.

[@davidalger9896]

I had a similar problem with my galvanized roof. I used Tremclad primer for galvanized metal for the entire roof, and then 2 coats of Tremclad rust paint. The Tremclad folks told me that I could use regular rust paint over the rusted areas, since the galvanized coating is all gone, and use the primer only over the areas that were not yet rusted. But I found it easier to paint the entire roof with both products. The roof was first prepared by power washing. Still looks good 3 years on.

Correct, you and some others have made the same comment, very good advice

[@lar4305]

I will stick to asphalt shingles, I know to many people that had metal roofs installed and had problems. maybe installation error i would think , but metal roof not for me.

[@mexisoc]

Metal is definitely the way to go . Up to 130 mile winds. This metal in this video is installed incorrectly from not having a proper transition metal to panels being installed improperly. I’m a roofer and I would never get shingles . If you get metal installed properly, it will last a long time. Put it like this, go and rip a shingle with your hands and then go and try that with metal.

[@lar4305]

@@mexisoc Do you need to change the screws after so many years because the rubber gaskets dry out and fail?

[@TroutGravyWithPancakes]

@@lar4305 YES you do. The gaskets dry out when the screws start to work their way out of the wood due to thermal expansion. If the screw is still tight then the gasket should not fail. Luckily ZXL woodbinder screws are now available with a 40 year warranty. My metal roof is 20 years old some of the original #12 screws are starting to pop up. I'm replacing them with #14 ZXL with a bit of Lexel caulk and don't expect to have the same issue for many years to come.

It needed flashing at the transition.

[@TroutGravyWithPancakes]

You've created a water dam at the upward most part of the repair. If this repair was done in and area where water freezes during winter the ice will undoubtedly start breaking the silicone from the metal. You should have feathered the upward most part of the repair.

[@danielbell5839]

He should have installed wakaflex on top of the lower section and tucked it under the upper panels this would allow for a 11 inch water diverter. I would never install silicone on a transition it essentially blocks or dams water not just that extreme hot or ice will split silicone.

[@richardbanks9519]

You didn't mention to paint over the fleece after you applied it

[@MexicanJewelry]

Yes you’re right maybe because is diferente material?

[@richardbanks9519]

It's the only way to correctly use the fleece, you have to apply a liberal base coat, then the fleece then paint over so none of the fleece is showing

[@joecanadian3099]

You said your self in other videos to never use silicone, then you use it.. Shaken my head

[@FlatRoofDoctor]

You are confused. I said bot to coat entire roofs with "Silicone" and I have said never to use "Silicone Caulking" That is completely different than using a Silicone-based product to do flashing or repairs. The Silicone composition in Silicone Patch or in Super Silicone Seal is much different than that is found in Silicone Caulking or Coatings. Canadians are really ganging up against me.

[@kimedmonds1503]

I keep a box of disposable rubber gloves on hand to protect myself from the solvent based cleaners tearing my hands up and to keep the silicone off. You may want to try using a SEBS product instead of silicone on metal roofs. SEBS is specifically designed for metal. SEBS products are a rust inhibitor.

TOM PIPPS FOAM- BATON ROUGE LOUIDISIANA USA HI HELLO &

[@redpost2380]

Doc, these videos are great because they highlight the many problems metal flat roofs have. You had a choice. Make the transition OVER or UNDER? Doc the OVER transition has already failed you have made the same mistake twice but with that better but expensive silicon material you sell. You are too experienced not to know that the LONG TERM solution is a metal sheet that is fitted and properly fixed UNDER the inclined sheets. Lead flashing would be malleable and long lasting but with poisoning issues due to acid rain etc. One solution is 8" butyl backed aluminium flashing that goes under the inclined metal sheets. There are a multitude of flashing rolls that if properly fitted would last as long as your silicone BUT unlike your silicone material they are MUCH EASIER to remove and replace in 20 years time. When preparing the surface, take care of your and your wife's health by wearing protective gear not just for the eyes but hands and nose.

[@FlatRoofDoctor]

you are absolutely correct.; The only difference is your method that you are describing is much more expensive and regular home owner will not attempt it. So compare apples with apples. That repair was done over a year ago, and the owner is still very happy.

[@traceyjscott069]

I agree Tracy, but it is a fix. If had some metal to slide under, I would have done so. But this fix worked as well and I just wanted to show how to make a transition no matter the situation.

[@amersfoortsefotograa]

With all respect for your efforts, but you say you are The Doctor? In civilian clothes and no kneepads working on the roof? This repair is just the sort of repair that a home-owner himself would do. A true craftsman would make a mechanical and not chemical repair, i.e. a transition slab under the upper sheet and over the bottomsheet with sufficient overlap. If we would work like you do, we would not have so many satisfied customers...

You are absolutely right. The way you describe a repair would be by far better than what I did. I tried out this product and 3 years later it still works. We never charged the homeowner.

[@thatolddragon5560]

I am dealing with this very situation, a transition from roof of house to porch. The way that looked when you were done, looks like it would catch water at the top part of your patch because it is way too thick. Being too thick, the water would pool at that location and over time, would have to fail. If it were feathered out at the top and made thin, where the water would easily flow over it, I think it may actually work. the way you did it, where it's thick at the top, I don't see no-way it wouldn't leak. Just my observation, and this isn't my first time doing a DIY job.
