Full Answer

Shingle roofs are usually made of asphalt shingles that can last up to forty years under perfect conditions. The average life span varies greatly in different climates. Shingles last much longer in cooler climates than in hot climates. Thermal shock that occurs in areas where temperatures change dramatically in short periods of time causes damage to shingles due to their inability to expand and contract. Flat roofs fare worse than sloped roofs since moisture cannot drain away. Acts of Nature such as hurricanes, hail storms, high winds and tornadoes can unexpectedly destroy even new shingle roofs.
