This building material consists of several layers of canvas and fibreglass felt. These layers are impregnated with special bitumen on both sides. The asphalt layer is reinforced with recycled polymer solutions that provide additional flexibility, resistance to deformation and durability.
Asphalt roofing shingles can have different life spans in different weather conditions. In cooler climates like Aylmer, shingles tend to last longer than in warmer climates. External factors, such as fungus buildup or over-accumulation of moss and tree debris, can potentially shorten the life of shingled roofs if not addressed in a timely manner.
Another important factor affecting the life of a shingle roof is the quality of ventilation in the attic. This is extremely important, as many roofers do not properly calculate the ventilation needs of the roof.
