Roofs are very strong, but they don’t last forever. Depending on material, the roof should be replaced after a few decades. The maximum lifespan of asphalt shingles is 20 years, for metal is 60 years and tile can even reach 100 years. But maximum isn’t average and the lifespans of roofs can be cut in half because of bad weather, lack of maintenance, severe storms and improper installment.
