Q: Should a two story home have insulation under the roof in the big closets ?: Any and all insulation helps wherever you put it! =)

Q: How much insulation is required in a house roof in new York ?: The US Dept of Energy provides online calculators to answer your question based on your zip code.

Q: I need to call around and find a contractor to repair my roof. I thought it might be a good idea to at least have the name of this type of roofing correct so I don't sound like too much of a mark. Thank you in advance for your assistance.: Spray foam insulation.

Q: p/t deck on a commercial rubber roof do we need closed cell insulation under deck to protect rubber?: First I would put some walk pads down, I don't know if you can purchase them at your local home center. There should be a specialty store that sells vinyl siding they should have them they are about two foot by two foot rubber squares that have dots on them they look like suction cups. Place these pads dots down so that water will drain under the pads, then place a piece of 2" x 8" about 16" long of p/t blocking on top, this will help transfer the load of the deck on the rubber walk pad on the rubber roof. Place the pads and blocks where ever you place your 4" x 4" s You are now ready to start framing the deck. GOOD LUCK!!!

Q: what action should a plumber take?????: struggling to understand your question! are you talking about a storage tank? what is the problem with the insulation? if it is in the way move it but insulation under a tank is not a problem the tank will need to be insulated any way!

Q: I have 4 pieces (about 50 sq ft) of odd shaped polystyrene foam insulation between 3&quot; and 4&quot; thick. it's leftover from installing a flat roof. creative ideas anyone?: I'm a bit confused here Andy. If the flat roof needs replacing, when it is removed what is revealed is going to be exactly what you would see if you removed the ceilings. So why consider removing the ceilings if they are ok? When the flat roof is replaced put the insulation in then. Whilst rockwool would have been the material to use there is now roofing insulation board that is much more efficient, 50mm board gives equivalent insulation of something like 150mm rockwool. If the flatroof isn't fitted with suitable vents to keep it ventilated fit them when the roof is done too. The only reason I can see for replacing the ceiling plasterboard is if it hasn't got a vapor barrier ie foil backed board.

Q: Our end unit 1940&quot;s row house has an old leaking bitumen roof . The water entry point can not be found so a replacement seems the way to go. A roofer suggested a replacement using Firestone 180, 1/2 inch fiberboard insulation covered with fiberglass base sheet, bitumen for flashing and fibered aluminum coating on wall coping . It's all Greek to be but fiberboard insulation and flashing material ? Should I be concerned?: We use kingspan insulation, marine grade plyboard , 3/4 inch, and yes you can use bitumen as flashing. I hope i am not being condescending, but the flashing is the bit that goes from the roof and a little way up the wall and is then "pointed" into the bricks, thus forming a water-proof barrier.

Q: is it safe to put insulation in the corners where the roof meets the wall in attics?fiberglass in corners?: No it is not EVER safe! Roofing material needs to breathe. Anywhere that insulation is applied to the underside of the roof deck the roofing material will warp and then leak. You have to have a cushion of air between the underside of the decking and the insulation

Q: i have roof insulation but if i add more to the required depth the bottom layer will get compressed. Will it still insulate?: Simple - make your bottom layer 1" styrofoam sheets- it has a higher R value per depth (1 inch of styrofoam is equal to 4 inches of fiberglass ) and it will not take-up much space and it will serve as a vapor barrier - and it will not compress when covered by fiberglass insulation. (So you can add as much R value as you want - as much as you can afford - with styrofoam sheets because they take-up such small depths in your rafters --- Also, humidity, as on rainy days or sunless winter days, decreases the R value of fiberglass -- weather conditions do not affect the R value of styrofoam sheets.

Q: I would like to know which direction the one side with foil faces. The roof or the interior of the room?This is an attic room. Roof being &quot;raw&quot; i mean that it looks like cedar tongue in groove boards...then shingles on top of them. Which way do i face the foil side of the sheet..?thanx: The foil side should go to the outside. I believe it's a moisture barrier.
