The Third Estimate

Over time your roof will experience wear and tear, but being proactive about maintenance will keep it aging gracefully.

Major Causes of Roof Wear

As with most things in life, your roof is bound to wear down over time. The Third Estimate team is here to share some of the most common causes of roof wear. The highest degree of wear occurs at the edge of your roof, where cedar shakes and asphalt shingles tend to get worn out faster. Because these edges take the brunt of wind during a storm, it's critical to choose a roofing system with high wind ratings and adhesive-reinforced starter strips.


High winds are a leading cause of roof wear and tear. High-wind damage is a result of debris being blown across your roof. The most common culprits are overhanging branches of trees and tree limbs. To prevent roof damage from wind, keep overhanging trees trimmed.


In addition to the usual deterioration caused by sunlight, hail is one of the most common causes of roof wear. Hail damage causes holes or dents in the roof, creating a perfect breeding ground for mold and rot. Furthermore, continuous exposure to water makes the roof structure weak and susceptible to sagging, posing a safety hazard. Thus, hail damage must be addressed as soon as possible.

Tree branches

If you have a tree on your property, you should trim it regularly to prevent it from causing damage to your roof. Tree branches can cause wear to your roof because of their weight and can damage roofing tiles and shingles. They can also clog gutters and cause moisture to seep in. Therefore, trimming tree branches should be done by a professional. Continue reading to learn the benefits of pruning your tree.

Ice dams

If you're wondering if you should fix your roof this winter, you should know that ice dams are one of the biggest reasons that homes lose heat. They can be extremely dangerous to remove, and the damage they cause is not only aesthetic, but can affect the health of your home and your family. If you're already suffering from chronic allergies or asthma, ice dams can aggravate your symptoms. Fortunately, there are several simple measures you can take to prevent or remedy roof problems.


The accumulation of snow can cause extensive damage to a roof. Heavy snow and ice, can weaken the structure of a roof. Especially in areas with low support, flat roofs, or lightweight materials, the weight of snow is particularly damaging. Ice dams can also result in structural damage and leaks. Ice dams can even pose a health hazard, especially if they cause leaks.

Poorly installed gutters

Besides the obvious reasons, improperly installed gutters can lead to serious damage to your roof and home. Rainwater falls on your roof and seeps into the gutter installation. When the gutters are blocked, water can sit on the roof or in the gutter system, damaging the home's foundation and attic insulation. Moreover, water can seep into your basement, causing significant damage to your home.

Improperly maintained rooftop equipment

Inadequate maintenance of rooftop equipment can result in a deteriorated roof. For example, improperly maintained metal flashings can rust. Metal flashings should be painted and properly sealed. If any areas of a metal roof exhibit rust, they should be repaired before structural damage occurs.

Final thoughts:

Just like everything else, your roof will experience wear and tear as it ages. In order to protect your roof and the valuable lives and possessions it protects from the elements, you must be vigilant and proactive to maintain it. When properly maintained, your roof will serve you for many, many years.
