Our roof is BLACK shingles, the attic gets hot-hot-HOT!This year, our Air Conditioning bill hit new record levels…. it was always too hot to put the foil up, until now… on a rainy day.Two weeks… every day, sunny or not, the attic temperature is virtually the same as the rest of the house – we’ve recorded temperatures of 135 degrees in the summer with our remote weather temperature sensor.I just checked, it’s 2:30pm, and the attic is 73 degrees, bright sunny day, it’s just 73 degrees – no solar gain in the attic!When installed, we left gaps at the base of each sloping wall, and the peak – just in case there was an excess heat buildup, we thought. This bubble foil stapled directly to the underside of the roof, I would NOT put it on the flat part, because moisture will not penetrate it. The bubble foil is strong enough to resist tearing, and though it goes up easily, maneuvering around the trusses takes the best part of a day, particularly in the narrow spaces along the edges. 2-3 kids can handle it a lot easier than a 6’3″ adult. Once they got into the tall open spaces, it goes up quick, by comparison.For the flat part of the attic, we’re going to use perforated foil, stapled down, and more insulation on top of that.The perforated foil will allow moisture to pass through, instead of soaking the insulation, rotting wood, etc.I think this would last a long time, given it’s not exposed to direct sunlight.
