Roofing

You can find two basic sorts of roof construction, sloped (also referred to as pictched) and flat. Most sloped roofs are covered with individual pieces of shingling material overlapped to prevent water penetration. flat roofs are fundamentally watertight membranes that ought to have just adequate slope to allow water to run off. The slope of a roof can be a issue within the life expectancy from the roofing material. The life expectancy of a roof covering is also dependent upon the kind of material applied, the good quality of workmanship, exposure to sun and wear from tree branches, snow/ice and wind. For example, south and west roof faces have a larger wear factor than north or east exposures, extremely reflective shingles tend to possess a longer life expectancy, and cement or slate roofs final substantially longer than standard ashphalt shingles (and expense a lot more!)

Asphalt shingling may be the most typical roofing material used in residential building in Canada. Other forms of covering for sloped roofs include asphalt roll roofing, concrete or clay tiles, wood shakes and shingles, and slate shingles. There are also fibreglass shingles, metal shingles and metal sheet roofing systems.

Flat roofs are constructed up with layers of molten asphalt and felts, or covered using a membrane of modified bitumin or asphalt base, or plastics or rubber. Most are heat-sealed and some are glued.
