Roofs are made to be durable, but just how long they hold up is dependent on what type of materials your roof is made of. Asphalt shingle roofs have the shortest lifespan, lasting for an average of 12 to 30 years. Cedar shake roofing tends to be more durable, and usually only needs to be replaced every 30 to 50 years. Metal roofing lasts even longer, with an average lifespan of 40 to 70 years. But slate roofing is the most durable of all. A slate roof only needs to be replaced every 75 to 100 years on average, and may last for as long as 200! If you have a slate roof, you probably won’t need to replace it in your lifetime.

Repairs can extend the lifespan of your roof substantially. Generally, having damaged roofing repaired every few years will be much cheaper than having your entire roof replaced. However, if your roof is decades old and continually needs repairs to stay impermeable, then it would probably be more cost-effective to have it replaced.

Bad weather can have a significant impact on the longevity of your roof. Minnesota has a changeable climate, with temperatures in the upper 80s and 90s in summer, and sub-zero temperatures in winter. Such dramatic shifts in temperature cause roofs in Minnesota to degrade faster than those in more temperate climates. Storm damage can also weather your roof quickly. Hail, strong winds and heavy snow accumulation all taking a toll on roofing, necessitating a premature roof replacement.
