Factors Effecting Roof Lifespan


What Hail and High Winds Can Do to Your Roof

Hailstorms, torrential downfalls and strong gusts of wind can cause various roof damage. Largely, the severity of the damage depends on the frequency of intense weather, the integrity of your roof and the duration of the storm. Thus, we recommend proactively checking your roof after heavy storms. Detecting signs of weakness early can prevent bigger issues like leaking during future storms.

The Effects of Hailstorms on Your Roof

The size, shape and density of the hailstones determine the threat posed to your roof. A jagged shard of ice can do more damage than a round one because it can pierce your roof easier. Likewise, a dense hailstone is dangerous because of its heft and impact. 

When hail strikes the same spot repeatedly, the stress created can lead to a bevy of structural problems. Most commonly, hailstorms produce discolouration, holes, dents and cracks. Such damage is scattered along the roof and hard to detect at first glance.

The Effects of Strong Winds on Your Roof

Unlike hailstorms, wind damage is often concentrated around the edges of the roof. Over time, though, if untended, it can cause strips of missing shingles up the sides.

Persistent gusts of wind create stress points on a roof that loosen shingles, leading to lifts and cracks. Worse, wind can carry debris onto your roof—glass, tree branches and more. Debris scratches at your roof and can get lodged between crevices, blocking the flow of water. Removing debris from your roof is a top priority after a severe storm.
