Summer Roofing Tips for Texas Homeowners: Protecting Your Roof in the Heat

Attic Ventilation: The Biggest Factor You Can't See

On a 100°F DFW afternoon, a poorly ventilated attic can hit 160-175°F. The decking bakes. The shingles above bake from both sides — solar gain from above, trapped heat from below. The asphalt binder breaks down faster. The fiberglass mat becomes brittle. What should last 25 years lasts 15. The fix isn't complicated: proper ridge venting at the peak, continuous soffit venting at the eave, and no obstructions blocking airflow between them. The Air Vent standard is 1 square foot of net free vent area per 150 square feet of attic floor space. A lot of DFW homes, especially those built in the 1990s with partial ridge vents, are running at half that. Check your attic in July — if the air hits you like a furnace the moment you open the hatch, you have a ventilation problem.

Storm Prep Before July's Afternoon Cells

DFW's summer storm pattern is predictable: heat builds all morning, and by 3-5pm, pop-up thunderstorm cells form over the Metroplex. Most are 60-80 mph straight-line wind events. Some include golf ball hail. If you've been putting off that flashing repair or that one lifted shingle since spring, summer is when you pay the price. Before the July storm season peaks, walk your perimeter and look for: pipe boot collars that are cracked or split from UV exposure, any shingle tabs that are lifting on the south or west slopes (most UV-exposed), gutters with loose hangers, and any tree branches within striking distance of the roof. None of these are dramatic repairs, but each one is a potential water entry point in a 70 mph gust. Fix the $200 problem before it becomes the $4,000 problem.

Granule Loss: What's Normal and What Isn't

After a summer of DFW heat, check your gutters for granule accumulation. Some granule loss is normal over the life of a shingle — new shingles shed loose granules for the first year or two, and that's fine. What isn't fine: heavy granule accumulation after year 5, bare spots visible from the ground on shingles that are still mid-life, or granule piles in downspout splash blocks after every rain. Granules protect the asphalt layer from UV degradation. Once they're gone, the shingle deteriorates rapidly. The south and west slopes lose granules faster in Texas because of solar exposure angle. If you're seeing significant loss on slopes that are less than 15 years old, call us and we'll tell you what you're actually dealing with.

End-of-Summer Inspection: Catch Storm Damage Before Winter

September is the right time to inspect your roof coming out of storm season. You want to identify any hail or wind damage from the summer storms before the fall deadline on most insurance policies. DFW's storm season runs March through September — by October, the big events are mostly done, and the inspection window for filing summer storm claims starts narrowing. Check your attic for new water stains after any summer storm. Check your soft metals — HVAC fins, gutters, vents — for impact dents from hail. If you're seeing anything that looks like storm damage, get a professional inspection before October. JRH does free storm inspections across DFW — call us at (469) 888-6903and we'll come take a look.
