How Does Summer Weather Affect My Roof?

Many homeowners think that summer is the time of year they have to worry about the least with their homes. And why wouldn’t they? Autumn brings falling leaves to clean out of the gutters, winter has heavy snowfall and ice, and spring has heavy rains that can result in water damage.

But summer roof damage often goes unseen, which can create more insidious damage than the damages of other seasons. Keep reading to learn about the dangers summer can pose to your roof.

Storm Damage

Thunderstorms are rare in the Pacific Northwest, but we aren’t fully immune to them. Thunderstorms can bring high winds, heavy rains, hail, and lightning. All of these hazards pose serious risks to the integrity of your roof.

High winds can grab the edges of curling shingles and pull them off your roof entirely or out of place. Missing or loose shingles allow space for water to leak into your home, causing water damage.

Heavy rains can contribute to any amount of pre-existing damage to your roof, but the more pressing damage comes from hail. One piece of hail can have a diameter of a softball, and the damage a chunk of ice falling at a high speed can cause is immense.

Most roofing systems dispel any direct lightning strikes, but the danger from lightning does not come from a direct strike. Lightning can cause major damage to your roof by striking something near your home that then falls onto (or into) your home.

UV Rays

We protect our skin from overexposure to UV rays for a reason. Unfortunately, there is no recommended SPF for your roof during the hot summer months. UV rays are around all year long (even on cloudy days), but the extended hours of daylight during summer means your home is getting even more exposure than during other seasons.

This increased exposure can cause your roofing material to dry out. This means untreated wood tiles bleach and crack and asphalt shingles can buckle and split.

Heat

If the temperature is 90°F, your roof will reach about 160°F. This excess heat can speed up the process of UV damage, but if your attic isn’t properly ventilated you could be facing cooling issues and a buildup of condensation that will lead to other issues, such as mold.

Thermal Shock

Another issue brought on by extreme summer heat is something called “thermal shock”. Thermal shock happens when the temperature drops from the high daytime heat to cooler evenings. The heat of the day causes the roof to expand, but it relaxes in the lower temperatures of the evenings. This is a relatively quick shift for any material, and expanding and contracting so much weakens the integrity of the materials over time.

 

A homeowner whose roof is under 10 years old and has received regular maintenance will likely be fine. Your roof is just like any other investment in your home. Taking care of it and keeping an eye out for irregularities will ensure it lasts longer. You should always keep an eye on the integrity of your roof, but don’t be afraid to call the professionals to perform a roof inspection if you aren’t sure you can tell what shape your roof is in.
