How Often Should You Replace Your Roof?

Do you know whether to replace or repair your damaged roof? Most homeowners have to replace their roof at least once, but the lifespan of a roof can vary widely–even among houses in the same neighborhood. Here are 5 things to keep in mind when you’re considering roof replacement in Marietta.

Type of Roof

Some roofing materials are naturally more durable and tend to last longer than others. Asphalt roofs–the most common type of roof in the United States–typically have the shortest lifespan, lasting about 20 years before they have to be replaced. Wooden roofs often last 20-30 years or even longer in some climates. Tile, cement, and slate roofs may last up to 50 years, while metal roofs take the prize in durability, with some lasting upwards of 100 years.

Wear and Tear

Examine your roof twice a year for signs of wear and tear. If you notice that all of the granules have been worn away from your shingles, for instance, it’s a sign of an old roof that needs to be replaced. Wear and tear is usually caused by harsh weather conditions like rain, snow, and wind. For this reason, homes in environments with frequent severe weather will have to replace their roofs more often than those in mild climates.

Wear and tear can also be caused by tree branches repeatedly rubbing against your roof. If your home is surrounded by trees, expect to replace your roof more frequently.

Roof Damage

If you see severe signs of damage to your roof, you will probably need roof replacement. While a few missing or damaged shingles can be repaired, damage to large sections of the roof is a sign that it’s reached the end of its useful life. Look for sagging areas or large patches of mold or moisture as telltale signs of roof failure.

Roofs that often lose shingles or suffer other minor damage are also likely to need replacement sooner than roofs that accumulate less damage over the years. By inspecting and maintaining your roof several times a year, you can extend its life by as much as several years.

Home Damage

Inspecting your home for water damage is another good way to tell if your roof has started to fail. Damaged roofs often cause leaks in the attic and other associated problems like rot and mold. They can even cause significant structural problems like foundation failure. These signs usually indicate severe damage to your roof, and you will most likely have to have a new roof installed.

Installation Quality

Roofs installed by experienced professionals last much longer than those that are put up sloppily. Roofing in Marietta requires a lot of attention to detail and should be done carefully so that the end product is as strong as possible. If your last roof was put up too quickly by someone who didn’t take the time to do the job right, you’ll probably have to have it replaced relatively soon. On the other hand, a roof that is installed correctly will be better prepared to stand up to the elements and will last for many years to come.
