Q: Our roof tile is installed on top of galvanized iron sheets. We do not have any toher form of insulation. The roof tile or tegula is quite thick.: You can never have too much insulation, esp. in a roof. Heat rises, and a well-insulated roof helps with energy savings.

Q: No insulation was installed under roof of my 2 story home. Im not rich but looking for info on installing about 450 ft. up there.: If there is no existing insulation you need a vapor barrier 1st or you need "faced" fiberglass, the one with either plastic or brown paper on it. I put it as thick as you can afford.

Q: 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.

Q: I have an apartment building that has mold in it. I'm trying to do everything I can to increase the airflow. Sure, the tenants might have to spend a mint on heat, but if it improved the air quality, maybe it would be a good idea.: Don't remove the insulation, unless it has mold in it too. Locate the source(s) of your mold problem inside your building... a high rate of interior bulk moisture, and eliminate that. Then make sure the bathrooms have exhaust fans that are wired-in with the light switch (so whenever someone turns the light on, the fan comes on too), and that the fans are vented out of your attic (otherwise you'll have mold inside your attic). Also, make sure the kitchen exhaust fans vent outside (and the clothes dryers too).

Q: should thermal insulation ever be applied directly to the underside of a roof top?: yes its done all the time on metal buildings. works well but expensive.

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: a roof that is built with the insulation covering the waterproof membrain is ?: a foolish product of college education in the building trades. it's pretty much taking over. real tradesmen saw that ship sink a while ago and are getting better at treading water.

Q: 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.....: Insulate the ceiling, not the roof. Place the vapor barrier (foil or heavy paper) facing the garage. For Alberta you want at least R-30, or 9" of fiberglass insulation. The garage should already have eave vents, hold the insulation away about a foot from them so the insulation does not block the air flow from them.

Q: The roof does not have fillet under tiles, our house tends to be very cold and we want to remove the insulation and put a knew one, will our house be warm? any tips and advice.thank you for your time: Don't remove the old insulation , put new insulation over the old , making it double insulated. As suggested above blown in insulation is really good

Q: What's better- to lay out roof insulation in an old house or to get it blown in?: Blown in. It's better and also cheaper to have the insulation blown in. It's better because the insulation will go around wires, ductwork, and pipes much easier. It can get into nooks and crannys easier. It's much quicker also.
