Thanks for these videos! Super helpful for the homeowner DIY’er. I’m curious about the tie in of stucco walls with parapets - is the exterior stucco supposed to come up and OVER the top of parapet wall? Or can the stucco terminate at the top of the parapet, with underlayment and torchdown then rolled a few inches over the exterior stucco? I plan on capping parapets with Spanish tile - a typical LA flat roof home.
I'm from Toronto canada the one thing we do differently is we torch a strip of base going half way on the metal flashing to cover the nails then the cap sheet the same way you did so the metal gets 2 ply
I have heard it done that way, and actually have had a conversation with our technical rep about that. I am not sure I see the benefit. The net surface area of torch to metal is the same. They say that if one fails there is a backup ply essentially. I don't really see the point. Would love to hear your feedback.
@@RoofRepairSpecialist the thing is if the nails push up over time, which let's be honest sometimes they do... their heads are hitting the midply and not just instantly trying to poke through your cap sheet
I do this on my jobs but in reverse. Flashing on top of base and then a piece of base over the flashing and the cap ontop of that. Water would have to get through 2 layers instead if 1 layer like this
We use a smaller torch - Detail torch and are just careful in holding the torch in the correct direction. If you want to be extra careful you can always torch then flop.
Will it work like this if I install wood stove pipe on a 1/12 pitch roof? The roof has existing torch down bitumen. If I will use a standard chimney kit for cathedral ceiling. It comes with a storm collar rather than a tight seal like this video.
Two questions: 1. Does the poly glass mid ply mfg sell patches, or just rolls? 2. Do you have a link? I am only doing one penetration for my stove pipe, so I don't need a whole roll. I have self-stick underlayment on the plywood and then torch down for the finished surface. Thanks.
