In Canada, fiberglass-based asphalt shingles are by far the most common roofing material used for residential roofing applications. They are easy to install, relatively affordable and last 20 to 50 years. Asphalt shingles come in a variety of styles and colours.

The protective nature of paper and fiberglass asphalt shingles primarily comes from the long-chain petroleum hydrocarbons. Over time in the hot sun, these oils soften and when rain falls the oils are gradually washed out of the shingles. During rain, more water is channeled along eaves and complex rooflines, and these are subsequently more prone to erosion than other areas.

Eventually the loss of the oils causes asphalt shingle fibers to shrink, exposing the nail heads under the shingles. Once the nail heads are exposed, water running down the roof can seep into the building around the nail shank, resulting in rotting of underlying roof building materials and causing moisture damage to ceilings and paint inside.

Other ways to spot if you need new shingles include algea growth (it looks like green moss), curling, buckling and missing granules on the shingles.
