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.
Most typically, it's a sprayed polyurethane foam system. Simple repairs can be made with a sealant, unless you need a section replaced.
I know when you inhale the insulation from the roof irritates the throat but what can you do to clear it from your throat after inhaling it?
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.
I have 4 pieces (about 50 sq ft) of odd shaped polystyrene foam insulation between 3" and 4" 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.
If I insulate my roof, should I put in those plastic vents that go between the studs for air flow? I would like to use it for a work shop and probibly have some kind of heat source. i live in Northern Alberta.....
Insulating the ceiling and then the roof would be a huge waste of money. You only insulate on the cold side of a heated area. Why would you put insulation on the roof when you have insulation in the ceiling and there is no heat source in between the two?. Put R40 insulation in your ceiling, roof vents in your roof, and you will be fine. You can add more insulation if you want, but it gets to the point where you are not really doing much any more.
Have a patio with metal roof, gets very hot during summer. Will Great Stuff insulate and stick to hot roof during summer? Thanks
I don't think Great Stuff foam insulation is meant to be applied in the manner in which you need. It is used to fill gaps and cracks, not be sprayed out in thin coats. whenever I've used it in the past, I found out it did not like to be spread out, or "worked".
the best way to thermal insulate and water proofing of rcc slabs economical, may be some poly urethane material or whatever but should be very effective and light weight.

I have a converted loft which is really cold. The roof doesn't have any insulation, just a waterproof sheet, but i don't want to spend too much insulating it with the proper boards. If i use mineral wool and staple it across the roof trusses will it do a good job?
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.
