You probably don't think much about your roof until something goes wrong. However, there are many threats to your roof every day. If you would like to know more about roof damage, check out these four common causes of roof damage.
1. Age and Wear/Tear
Roofs only last so long, so some damage is simply caused by age and general wear and tear. The life span of the roof largely depends on the material. Asphalt, metal, and wood roofs, for example, are affordable, but they don't last as long as slate or clay, which cost more. Naturally, the more maintenance you put into your roof, the longer it lasts.
For this reason, it's important to understand the amount of maintenance each type of roof requires. Slate, for example, is expensive, but it requires little attention. Asphalt, which is more affordable, however, may experience lost shingles, decay, pest infestation, moss, mold, and much more.
2. Tree Branches and Limbs
If you have tree branches or limbs that hang over the roof, they could damage the roof. If a storm or big gust of wind breaks the branch, it could hit the roof, causing immediate damage. Even if the branch doesn't cause a hole or leak, it could ruin some shingles or flashing.
Debris from tree branches and limbs can also cause problems. Not only can they clog gutters, but they may attract pests or absorb water, which increases the risk of infestation and decay.
Weather constantly tries to damage your roof. UV rays can make some materials (like asphalt shingles) brittle. These shingles are more likely to crack or break free during a gust of wind. Wind can be detrimental to your roof. Not only does it rip off shingles, but it may loosen flashing or gutters.
Snow and ice may also pose a risk. Both snow and ice are heavy, and this excess weight can be too much for the roof. During freezing temperatures, ice dams can form if you have clogged gutters. Ice dams prevent the melted snow from draining.
4. Ineffective Drainage
Finally, ineffective drainage can quickly damage many parts of your roof. If you don't keep your gutters clean and/or ice dams develop, the edge of the roof may experience aggressive wear and tear. Water may collect in roof valleys, so it's important these valleys slope toward the gutters and have extra flashing for protection.
Your roof is an important part of your home, but there are many causes of roof damage. Luckily, with good maintenance and care, your roof should last a long time. If you would like to know more, contact a roofing company, such as Kerry Roofing & Masonry, in your area today.
