Seasonal roof damage can lead to major leaks and costly repairs. Certain types of damages are more common depending on the season. Knowing what they are can help you spot a problem early when repair needs are still small.
Summer: UV Damage
Sun damage is a major concern during the hot days of summer. The UV light breaks down asphalt shingles. The shingles can begin to look bleached out in color, and the granules may loosen and fall off as the asphalt breaks down and shrinks. If caught early, there are shingle treatments that can be applied that provide some UV light protection. These coatings can extend the life of your roof. More advanced cases of UV damage will require a new roof installation or extensive repair and replacement of damaged shingles.
Fall: Leaf Debris
With fall comes the colorful onslaught of autumn leaves. These leaves can form drifts on the roof and collect in gutters. Clogged gutters can cause water to backflow beneath shingles, which causes leaks. Piles of leaves on the roof can cause similar issues, as well as trapping moisture that leads to warped and curling shingles. Keeping a clean roof and gutters prevents issues. Otherwise, you may need to have warped shingles replaced and leak-damaged roof decking repaired or patched.
Winter: Ice Dams
Ice dams occur when water collects at the edge of the roof and freezes. Due to heat escaping from the roof, snow melts upslope from the dam, but it can't drain into the gutter because the ice dam blocks it. Instead, it flows under the shingles, where it either leaks into the home or freezes and lifts up the shingle. Ice dams can cause both leaks and shingle damage. Clean gutters and a properly insulated roof helps to prevent dam formation. Once a dam occurs, you may need to have the damaged shingles repaired and the roof insulation and ventilation updated.
Spring: Wind Damage
Spring rains are often accompanied by high winds and storm conditions. Wind can rip up shingles, twist flashing, and hit the roof with debris that causes punctures. Other than keeping the roof in good repair, there isn't much you can do to prevent wind damage other than be prepared to act quickly if repairs are necessary. Common spring repairs include shingle and flashing replacement, as well as puncture and leak repair.
