The most common steep slope roofing types are asphalt shingles, concrete and clay tiles and wood shakes and are most often associated with residential construction but can also be used for steep sloped commercial roofing as well. Metal roofing is used in both steep slope and low slope roofing applications.
Asphalt shingles comprise the largest segment of steep slope roofingand CWS carries all major brands. They are composed of fibreglass mats impregnated with asphalt. Because asphalt is easily degraded by UV exposure, a surfacing of varying colored mineral granules is embedded into the exposed side of the asphalt shingle that also imparts its finished color. Shingles are overlapped and secured by nailing through the roof overlay of felts or roof paper into the roof deck from the bottom of the roof slope to the high point of the roof referred to as the ridge. Special ridge vents are usually installed to provide ventilation from the attic space.
Concrete or clay tiles
In certain parts of the country, concrete or clay tiles are installed in overlapping "shingle fashion" on steep slope roofs as well. These tiles are usually installed with a combination of nails and cementitious mortar. CWS has certifications from several manufacturers in Europe and is a certified Concrete tile installer.
A growing segment of the roofing industry is metal roofing. CWS caries various types of metal roofs including metal shingles as well as long spans of metal panels. Metal panels are easily installed on steep roofs and are becoming more popular for their aesthetics and inherent fire resistance and are common in both residential and commercial construction.
Cedar shakes and shingles
A natural product that has been used for roofing for hundreds of years. Cedar roofs in Norway are know to be up to 100 years of age or older.
CWS has access to oldgrowth cedar shakes and shingles harvested and processed in BC. Installed on the proper pitch with the proper build up cedar shakes can last up to 50 years and can be treated to prolong life and stop moos from growing.
Composite shingles and shakes
The market for composit shingles and shakes is growing every year. CWS has installed many major brands of composites over the years. The benefits of composite roofing materials are minmal maintenance as well as lifetime warranties.
