Roofing paper is not required by the building codes, although some do now require a plastic or rubber membrane on the lower overhang that extends up the roof to a point 18 inches inside the exterior wall. Although felt paper is not required on the rest of the roof, most shingle manufacturers do r...
Cindy from Ajax, Ontario writes: We have an L shaped house, and our roof is in need of re-shingling (we are considering asphalt shingles). Where the two roof slopes meet in the centre of the "L" there is a major valley, quite long, with steep pitch. This valley is currently an open valley...
Getting something to stick to asphalt or asphalt coated materials is a unique problem. Asphalt driveways have their own specific crack sealers and roofing materials generally use what we call "Plastic Cement". (One exception to this is a specially formulated polyurethane adhesive that will work...
Ventilation in a Canadian attic does very little to remove moisture when the temperature in the attic is below freezing. During that time, the moisture is in the form of Ice and the passing air simply won't remove it -- whether you have passive vents or power vents. When things warm up, if the ...

A basement that has more than 50 per cent of its height sticking out of the ground is not really a basement. The walls should be treated as ordinary, above-ground walls. The foundations should be treated as slab-on-grade to avoid frost problems.
Interior/exterior insulation combinations can be u...
