In installations, the ordinary shingles are overlapped to produce a whole roofing weight of about 240 pounds per roofing square. The shingles are surfaced on the top face with mineral granules to give protection from the elements and an element of fire resistance. The shingles do let moisture to get away from attic areas in vapor form.
