Most homeowners believe winter and spring are the most destructive times of the year for roofs. That may be true in other parts of the country, but here in Southern California, it’s the relentless sun and fierce summer winds that can do a real number to your roof. Here are some of the hidden dangers that summer brings.
During an extended heatwave, old shingles are far more likely to crack. The sun’s powerful UV rays can dry out old shingles, making them more brittle. Cracked shingles allow extra moisture to seep into the roof sheathing below. It’s only a matter of time before a leak develops.
During the dog days of summer, it’s especially important to properly ventilate your home’s roof. Your roof could reach temperatures as high as 160 degrees. This extreme heat accelerates the chemical breakdown of shingles. That’s why it’s critical that your attic has adequate ventilation. Without proper ventilation, an excess amount of humidity and heat can build up in the attic. This extra moisture may ultimately cause the roof to weaken, which means repairs will soon be needed.
We’re no strangers to powerful summer storms. Strong winds and heavy downpours can take a toll on your roof. Reduce the risk of damage by trimming back tree branches and cleaning out your gutters at least twice a year. It would also be wise to inspect your attic for moisture after a storm to determine if your roof is leaking.
Bottom line: Damage related to UV rays and extreme heat happens gradually. A week-long heatwave isn’t going to create immediate defects. Roofs are built to withstand the elements, but a trained eye will detect minor problems before they become major. That’s why we recommend scheduling a roof inspection annually.
