Can East Texas Heat Damage My Roof?



It’s already here. You step outside and by mid-morning the sun feels like it’s starting to melt your skin. Running errands is exhausting because your car turns into an oven and you have to wait until evening to start your yardwork. We talk in winter about ice dams, but summer heat causes shingles to sizzle and support structures to expand.


East Texas Sun Bakes Roofing

Right now Dallas and Tyler have about 14 hours between sunrise and sunset. That length of time is still increasing. That number will creep up steadily until summer solstice on June 21, the longest day of the year in terms of daylight.

Extreme heat accompanies those long days. As they heat up, your roof decking, wood rafters and roofing joists expand. If you have plastic flashing, as it stretches it can begin to crack and allow moisture in to your home.

Asphalt shingles also expand and contract. As they do, the nails that hold them in place can come loose. The next time there’s a windy day, shingles can work loose and blow off your roof. Sunlight bakes shingles day after day to wear at the weatherproofing elements. Over time UV damage occurs and shingles might begin to crumble.

It’s hot all day, but this time of year nights are often much cooler. Temperature fluctuation causes materials to change size so they wear out faster than they would in milder climates. Warped roofing materials lead to leaks.





East Texas Humidity

It’s not just hot, it’s humid. High humidity can cause moisture to get trapped in your attic and lead to mold formation. Moisture and mold break down the plywood underneath your roofing material.


What You Can Do to Help

The best way to make your roof last is to inspect it regularly and be aware of potential concerns. We recommend the following:

  • Provide adequate roofing ventilation – When air circulates, it lets the heat escape. Older homes don’t always have adequate ventilation and new homes are airtight, so if they’re not properly ventilated heat and moisture are locked in.
  • Prevent excess moisture – Keep the indoor humidity to a minimum so excess water vapor stays out of your attic. Use a dehumidifier in damp basements, turn on exhaust fans when cooking and bathing, cover pots when you’re preparing food and vent clothes dryers directly outside.
  • Schedule regular roofing maintenance – Inspect your roof from the ground to see if shingles are showing signs of wear. Call an expert if you see cracked, crumbling or missing roofing material.
  • Replace your roof when it’s time – If your roof is in its last days, summer is a great time to replace it. You don’t want to wait for fall rains to find out your home is no longer protected.
