Back to Blog Roof Maintenance Seasonal Roof Maintenance Checklist for San Antonio Homeowners
Mark WhiteJuly 1, 20267 min read San Antonio doesn't have "mild" seasons. We have hail season, oven season, hurricane remnant season, and that one weird week where it freezes. Each one tests your roof differently. A little preventive maintenance each season can add years to your roof lifespan and catch small problems before they become expensive ones.
Here's the checklist I give every homeowner. Most of this you can do from the ground or a safely positioned ladder.
Spring (March through May): Storm Season Prep
Spring is San Antonio's most active severe weather season. Hailstorms, high winds, and heavy rain are all on the menu. Get ahead of it:
- Do a ground-level visual inspection: Walk around your home with binoculars. Look for missing, curling, or damaged shingles. Check flashing around chimneys, vents, and walls.
- Clean your gutters: Winter debris has been accumulating. Clear out leaves, twigs, and sediment so water can flow freely during spring storms.
- Trim tree branches: Any branches within 3 feet of your roof should be cut back. Overhanging limbs drop debris, scratch shingles, and can become projectiles in high wind.
- Check your attic: Look for any signs of water stains, daylight through the roof boards, or insulation that looks wet or compressed.
- Document your roof's condition: Take photos from all four sides. If a storm hits, these "before" photos are invaluable for insurance documentation.
Summer (June through August): Heat Management
San Antonio summers are brutal on roofs. Sustained 100°F+ temps, intense UV radiation, and thermal cycling (hot days, warm nights) all take a toll:
- Check your attic ventilation: Is air flowing? Can you feel air movement near the soffit vents? Is the ridge vent clear of debris? A well-ventilated attic shouldn't be more than 10 to 15 degrees warmer than outside air.
- Inspect caulk and sealants: Heat causes sealants to crack and shrink. Check around pipe boots, vent collars, and any exposed caulk lines.
- Look for blistering or buckling shingles: Extreme heat can cause shingles to bubble or warp, especially if ventilation is poor.
- Verify your AC condensation drain: The AC drain line runs through or near the attic. A clogged line can leak water onto insulation and decking.
- Consider a professional inspection: If your roof is over 15 years old, a summer inspection can catch heat-related degradation early.
Fall (September through November): Get Ready for Winter
Fall is cleanup and prep season. You're recovering from summer heat and bracing for winter:
- Deep-clean your gutters: Fall leaves are the number one gutter clogger. Clean them once the bulk of leaves have dropped, usually late November.
- Inspect all flashing and seals: Before winter rain sets in, make sure flashing around chimneys, walls, and valleys is secure.
- Check for animal entry points: Squirrels, raccoons, and rats look for warm attic access as temperatures drop. Check soffit vents, ridge vents, and any gaps along the roofline.
- Look at your roof from inside: Go into the attic on a sunny day. Any light peeking through means a gap that will let water in.
- Clear debris from valleys and flat sections: Leaves and debris that sit on the roof trap moisture and can cause premature deterioration.

San Antonio winters are usually mild, but we do get occasional freezing events. Winter Storm Uri in 2021 reminded everyone that Texas isn't immune to extreme cold:
- Keep gutters clear so melting ice and rain can drain properly
- After any freeze event, check for cracked or displaced shingles, as the freeze-thaw cycle can loosen nails and crack brittle shingles
- Watch for condensation in the attic during cold snaps, as warm moist air from your house will condense on cold roof surfaces if ventilation is inadequate
- Inspect pipe boots and rubber seals, as these harden and crack faster in cold weather
- If we get ice, do NOT try to chip ice off your roof. You'll damage the shingles. Let it melt naturally.
The Once-a-Year Professional Checkup
Even with diligent DIY maintenance, I recommend a professional free roof inspection once a year, ideally in spring before storm season. A trained eye catches things you'd miss from the ground: nail pops, micro-cracks in flashing, early granule loss patterns, and ventilation issues.
Think of it like a car. You can check your own oil and tire pressure (and you should), but you still take it to a mechanic for an annual inspection. Same logic applies to the thing protecting everything you own.
