Has anybody done spray foam directly over OSB or plywood? I'm looking for an inexpensive way to do a carport area that has rafters and I can install OSB
I live in S Florida and have a 1971 built concrete house - block walls and 6" slab decks and slab roof with elastomeric white roof coating. Zero Insulation. I have solar panels on stanchions and they are trapping heat between the panel and the roof, and the heat is passing through the roof. I've thought about laying tpo under the solar panels, but the time to cut/fit around all the stanchions, wiring, etc. is daunting. I'm wondering if a layer of spray foam insulation, topped with elastomeric roof paint might offer a solution. Any insight, experience, comments, welcomed.
The panels shouldn’t be trapping heat. If anything they should be shading the roof while also allowing an air gap. Are these panels new and you have just noticed some sort of significant difference, or have these panels been there long term and you’re just trying to sort out why the roof is allowing so much heat to pass through?
@@jimyeats I initially thought what you are thinking - ie the panels will shade the roof. In actuality, the heat transfers through the panels and then is trapped between the underside of the panel and concrete roof deck.....which according to thermodynamics the heat radiates through the roof to the inside of the house.
@@frederickmatthews4259 Maybe you have a very unique situation. I guess I could see if you have a flat roof and block sides that extend past the roof height and then solar panels on top of the roof and you have basically created a hot box, then maybe. But for everyone else out there solar panels on a standard roof reduce heat since the panels reflect sunlight, and there is an air-gap that doesn’t easily allow for the transference of heat, particularly on a normal roof where a breeze is removing that air between the panel and roof.
@@frederickmatthews4259 My apologies, I used the wrong terminology. It doesn’t change the fact that solar panels cool a standard roof compared to not having solar panels.
Not on this project. Granules are an option we give the customer the choice of whether or not they want them installed. On this roof there wasn't a lot of foot traffic so they were deemed unnecessary.
good applicator very clean nice job
Thanks, Roy!

Good foam is cliyinang and poam spray and coating pins this good
The inexperienced applicator had a lot of rollover 😮😂 😂
Does entire roof have to be done or could we say have have of a roof done? Will it blend well?
You can do it in sections, but the roof needs to be sprayed from the ridge down. If not, it will dam water.

@@jimyeats You are failing to understand the solar panels DO NOT reflect sunlight any more than a black asphalt surface reflects sunlight.

Can spray foam be removed with a 3000psi pressure washer after instalation??
No it can not be.
It's over 1.5 inches thick if it's a good installer it ain't coming off.
No granules ?

Pls send ur contact number
Seems like this would be a preventative maintenance nightmare.
I don't think this roof will last 10 years. Should have left the metal alone and insulate under with fiberglass.
This iryha
Don't make sense.
