Q:Can I put insulation on top of my roof and then roof over it with metal roofing?
The only downside I see is your miscalculation about the length of the screws need. Lets see, 2 inches of insulation, 3/4 inches of furring, leaves you with a solid 1/4 inch of bite, and we all know that the first 1/4 inch of the screw is meant for piercing, not holding. So plan on 4 inch screws, because you still need to penetrate the old roof and bite the structure. Don't forget to plan your drip edge which now will have 2+ inches of roof thickness to carry the rain water over into your gutter.
Q:How good is polyurthane spray foam for roof insulation?
we live in the desert, and got our roof coated, and instantly noticed the difference, it is much more insulated, and provides protection against leak (which was the main reason we had it done)
Q:ROOF INSULATION how to add more insulation on the outside!!!?
You could build a pitched roof on top of the flat roof.
Q:No ventilation between insulation and roof between knee wall & floor of attic. How can I provide ventilation?
That is an option. And there aren't many options.Not much is going to slide easily behind the insulation. I'm thinking --------------------. You are undoubtedly going to snag on roof nails coming through the decking. I don't know if they would hold up but the cardboard tubes wrapping paper comes on might work if you tape 2 together. and flatten and tape the end you will be pushing in first. cut slots with utility knife. I think your idea would work if you can afford the pipe. That's a tough one. When we convert attics we line those cavities with a styrofoam insulation chute end to end until we reach open ventilation-you probably know that by now. Give it a try.
Q:How do I insulate an attic with only 5 inches between the inner ceiling and roof?
u can buy blow in insulation. I think Home Depot even lets you rent the blower machine free if you buy a certain amount of bags of the insulation.
Q:Is mineral wool any good for under roof insulation?
Yes, be sure to leave an air space between the top of the insulation and the roof deck to allow for ventilation, and use a vapor barrier on the interior side of the insulation.
Q:I want to install roof insulation at my house?
No blowing in some insulation will help but putting insulation against the roof wont help. the attic area is supposed to breath to avoid condensation and overheating. The only thing you would put on the roof side would be to help cooling in summer since the shingles heat up the wood underneath and heats the attic, which then works down through the ceiling.
Q:If a roofing contractor offers an insulation material with an R value of 2.5 instead of 3?
You don't want that. If he offers 3.5 instead of the required 3, that is a different story. Otherwise he should give you more material thickness to provide an equivalent R of 3. Yes, the difference can be substantial and I wouldn't forward it to the client. The smaller the R value of the entire roof sandwich the larger the difference it makes. Like the change from 5 mpg to 4 mpg is a 25% worsening in fuel economy, but a change from 100 mpg to 99 mpg is 1%. It will mess up the heating/cooling of the building and the mechanical systems might be inadequate. They could save money on the roof and complain how the building is too hot/too cold or the mechanical systems never shut off and their energy bills are too high.
Q:Which is better for a 2-story house : radiant barrier roof or more attic insulation?
the best is more attic isolation so that the heat don't come directly to second floor.
Q:Inhaling roof insulation?
it's not your throat you should be worried about. it's your lungs. wear a respirator....or at the very least, a dust mask. you only live once so make it last.
