How to Install Pipe Flashing on a Torch Down Roof
HTML-код
- Опубликовано: 24 июл 2024
- Regardless of what type of roof you're working on, almost every type of roof has some type of flashings or penetrations that are going on. Whether you have a t-top installed or a pipe where you need to install a pipe flashing, these details are pretty much the same. We want to make sure we take a few extra steps to ensure that we have a good bond between our sheet metal and our asphalt surfaces. In this video, I'll show you how to properly install penetrations and flashings around them.
**Please note that torch down roofing is dangerous and should be installed by a licensed professional. Using an open flame can pose a fire risk and therefore must be handled carefully. Make sure to wear fire resistant gloves when installing torch down roofing.
Keep all flammable scrap and debris at least 10 feet away from the building. A fire extinguisher is needed within 50 feet of anywhere where more than 5 gallons of flammable or combustible liquids or 5 pounds of flammable gas are being used on the job site. No one on a job site can be more than 100 feet away from a fire extinguisher at all times. There must be at least one fire extinguisher for 3,000 square feet of work area.

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.
Good to have an idea thanks I will keep in touch with you 🙏🙏🙏
Any time
I like your videos ✌️👍
Thank you, I appreciate it. If you haven’t already always appreciate a subscribe.
thank you for sharing your knowledge, what do you do when installing the pipe flashing around PVC pipe so that plastic pipe dont gets melted?
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.
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
I’ve been contemplating that for a while and been thinking of switching that method. It’s a long conversation but I see the argument both ways.
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
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.
Definitely, sounds like you have a good plan.
What about for an already existing roof and you have to install new vents through it?
I'll be doing a video for this separately. Its pretty much a similar concept you will just install a 2x2 patch
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.
They only sell full rolls. If by any chance you are in the area around Los Angeles, feel free to stop by our yard, I’ll be happy to give you a piece.
@@RoofRepairSpecialist Thank you for the offer! In SD.
Why is pipe flashing and electrical mast flashing different?
Its not really different, unless i'm missing something. Electrical mast is a type of pipe.
Wire wheel and no safety glasses not a good idea😢
Point taken
your forgot couple more nails
