Composition shingles are the most common roofing material in North America. They are commonly made of either fiberglass or recycled paper based products mixed with asphalt, which is then covered with coloured mineral granules. While they have a low installation cost, composition shingles will usually protect your home for about 10-15 years.
Some composition roofs require maintenance or repair in as little as 8 years. This material can be easily damaged by high winds, causing the shingles to blow off. High heat, heavy rains and other weather factors can cause curling, cracking and streaking of the shingles, which deteriorates your roof's appearance and effectiveness.
