They're certainly not my first choice, but they're all too common in commercial structures and older row houses. The best thing that we can do is learn how to address the added risk factors.
Considering in building my home with a flat roof and from all the research I've done and videos I've seen there is not one company that can 100% guarantee that your roof will not leak. I say that because even when using your methods the life of the roof still depends on whether that employee is underpaid, mad at his boss or is just simply cutting corners......I really like the flat roof style though and with me being a welder what do you think about laying 1/8 aluminum sheets and Welding them together. I can source them oversized and I fabricate so not afraid to customize pieces to make it work.
How many sq ft will your roof design incorporate? I imagine that will get pricey quick I think Matt Risinger covered a very nice (and expensive) build in AZ that incorporated a flat roof with some interesting details if you’re looking for ideas
It 3,900. I looked for it but couldn't find it. Most of his videos though I saw he uses some type of hidden fastener panel. I'm thinking about actually just laying down flat aluminum sheets and welding it all together. Yea it's not going to be cheap but if I can pull it off that roof will literally be there forever. The metal that is normally used is 26 gage and has a 30-40 year warranty. I would use 1/8 and probably 16g for trim. My only problem is that I am not a roofer. I bought this guy's ebooks and cad drawings so hopefully I can figure out this science.
I greatly appreciate your presentation style and detailed explanations. I’m curious if your design guide covers a style I’m seeing more in the southern US which is a decoupled house / roof system whereby the house is well air sealed including a flat roof but has an external roof system - usually metal frame - that essentially covers the entire home. The cost maybe high, but the function of the home’s ‘internal’ flat roof is becomes functional with less loads and weather protection. Thanks!
Cheers! We have something similar that is discussed in the hot climate book, in which we recommend what is essentially a decking system on pedestals to shelter the membrane from heat and UV light. Same function more or less.
Great video thanks for posting. What are your thoughts on ballast for flat roofs to help keep the membrane in place and prevent drain blockage? Is it something you'd recommend? Also, what's the website you are scrolling through roof penetration flashing products?
@@martinsmith7562 Thanks so much, I'm not a fan of ballasted systems in the traditional sense, as I want to make sure that the roof membrane is completely bonded to the substrate of the roof, whether it's to a cover board or to the structural layer (I.e. using a fully adhered or fluid applied system). I am a fan of ballasts in the sense that it protects the membrane from heat and UV light. The website was Carlisle's detail manual.

Your level of detail and presentation style is deeply appreciated.
To my mind, flat roofs fall into the category of “just because we can, doesn’t mean we should.”

7:15 Love the "Don't cut corners..." :)
Nice work as usual, thank you!
@@Clark-Mills Thanks for watching!
I've already purchased the guide and this is great supplement material :)

@ASIRIDesigns thanks for the reply, I agree.
If you think flat roofs are hard to get to zero leaks, imagine doing this for under landfills. Same technology with even more risks.
