Will Your Roof Survive The Summer Heat? 3 Things To Consider
You may think your roof is fine if it's still intact after a chilly winter or rainy spring, but summer brings its own set of problems. Scorching heat isn't kind to residential roofing, and excessive humidity can also trigger issues. As the temperature increases outside, you may develop unexpected roofing problems or find that summer worsens existing issues. Evaluate the 3 factors listed below to determine whether your roof is ready to endure the sizzling summer sun.
What materials make up your roof? If you aren't sure, ask a residential roofing specialist to examine the exterior of your home. You may find that your materials are outdated or unequipped to handle high temperatures, which means you need to upgrade your roofing. This doesn't always mean you need a new roof, as you might benefit from a coating or sealant on your home.
Asphalt shingles are often used on residential roofs because they are durable and affordable. However, prolonged exposure to high temperatures can weaken your asphalt shingles and cause them to crack. This issue isn't unique to asphalt, though. You may also notice weather-related damage if you have any of the following materials on your roof:
- Solar tiles
Basically, there isn't a material that's fully immune to heat exposure, although some materials fare better than others under the sun. If your home undergoes enough hot summers, you may eventually notice some roofing issues.
Ventilation refers to how well air flows between your roofing materials and the interior of your home. Poor venting is not just a summertime issue, but it often becomes more apparent during hot weather.
Poor airflow can damage the materials under your roof. For example, it may dry out the tar paper under your tile roof or cause putty to crack or break. This is why many roofing companies suggest improving circulation with roofing vents or window fans.
In addition to drying out materials, the summer heat can also cause mold or leaks in your roofing. This happens when your attic or the upper level of your home remains significantly colder than it is outside, so moisture builds up between your roof and the top of your home. It's important to fix moisture-related issues as soon as possible because they can weaken your roofing and cause interior leaks.
The issues you ignored during the winter and spring might need immediate attention now. Small cracks can expand under the summer sun, which means that a hairline crack may transform into a deep crack before it breaks. Thunderstorms are also an issue, as the heavy rain of summer is often different than the light yet frequent rain of spring. Over time, heavy rain may weaken your roof, resulting in additional cracks or newly developed leaks.
Now you know how summer's heat and humidity can destroy your roof, so take action before an issue arises. Schedule a consultation with a residential roofing expert to learn how you can help your roof withstand the damaging effects of hot weather.
