Fall Roof Maintenance Checklist | Wannamaker

San Antonio doesn't really get a postcard-worthy fall. What we get is a compressed window — roughly mid-October through early December — where temperatures finally drop below 90, live oaks dump their leaves (often not until February, but other trees go earlier), and the first cold fronts start pushing through. That window is your best shot at catching roof problems before they become winter emergencies. Here's the checklist we use ourselves, adapted for homeowners who want to be proactive instead of reactive.

Why Fall Matters More Than You Think in San Antonio

Most roofing content talks about fall maintenance like it's universal. It's not. San Antonio's fall is different from Dallas or Houston in a few critical ways:

• Summer heat damage reveals itself now. Five months of 95°–105° temperatures stress shingles, dry out sealant strips, and crack boot flashing around pipe penetrations. Once temperatures cool, materials contract — and that's when small cracks become leaks.
• Hail season has a second peak. Many homeowners think hail is a spring problem. But San Antonio sees significant hail events from October through December as cold fronts collide with Gulf moisture. Getting your roof inspected before that window closes is smart risk management.
• Tree debris varies by neighborhood. If you're in Alamo Heights or Terrell Hills with mature pecan and hackberry trees, leaf and branch debris hits earlier. Stone Oak and far north side neighborhoods with more live oaks may see heavy leaf drop as late as February and March.

The Checklist: October Through Early December

You don't need to do everything in one weekend. Spread these tasks across the season, and prioritize the items that require professional eyes.

1. Clean Gutters and Downspouts (October–November)

Clogged gutters cause fascia rot, foundation erosion, and ice damming during rare freezes. In San Antonio, most homeowners need at least two gutter cleanings — one in late October or November, and another in late February after live oak leaf drop. Check that downspouts discharge at least 3–4 feet from your foundation, and make sure splash blocks or extensions are still in place.

2. Inspect Flashing and Sealant Around Penetrations

Pipe boots, vent caps, chimney flashing, and any rooftop HVAC curbs are the most common leak sources we see. San Antonio's UV exposure degrades rubber pipe boots faster than in northern climates — typically in 8–12 years versus the 15–20 years manufacturers suggest. Look for cracking, separation, or rust stains around these areas. If you can see daylight or cracking from the ground with binoculars, schedule a roof inspection soon.

3. Check for Missing, Cracked, or Curling Shingles

Walk around your home and look at the roof from all angles. Summer storms and heat cycling cause asphalt shingle granule loss, curling edges, and cracking. If you see bare spots where granules have worn off, that shingle is no longer protecting the underlayment beneath it. A few damaged shingles are a roof repair — a pattern of damage across the whole slope is a conversation about roof replacement.

4. Trim Overhanging Branches

Branches that overhang your roof by more than a few feet are a problem waiting to happen. They drop debris, hold moisture against shingles, and during ice storms — rare but real in San Antonio, as we saw in February 2021 — heavy branches snap and damage decking. Keep a 6-foot clearance between branches and your roof surface. Hire an ISA-certified arborist for large trees, especially heritage oaks that require city permits to trim.

5. Inspect Attic Ventilation

Proper attic ventilation isn't just a summer concern. In fall and winter, warm air rises into an unventilated attic, hits the cooler underside of the roof deck, and creates condensation. Over time, that moisture rots decking and breeds mold. Check that soffit vents aren't blocked by insulation, and confirm your ridge vent or turbine vents are turning freely. The general standard is 1 square foot of net free ventilation area per 150 square feet of attic floor space, though some code exceptions allow 1:300 with proper vapor barriers.

6. Look for Signs of Previous Storm Damage

If your neighborhood took hail anytime between March and September and you didn't get an inspection, fall is the time. Hail damage isn't always obvious from the ground. Dented soft metals (gutters, vent caps, flashing), circular bruising on shingles, and cracked tile roofing are all indicators. Most Texas homeowner insurance policies have a one-year filing window from the date of the storm, so don't wait until spring to discover you've missed your deadline.

7. Check Interior Ceilings and Walls

Water stains, bubbling paint, or musty smells in upper-floor rooms and closets often point to a slow roof leak. Fall is when these tend to show up — summer's heat dries moisture quickly, but as temperatures drop, water lingers. If you find interior water damage, don't paint over it. Find the source first.

What Not to Do

A few things we see homeowners do every fall that create more problems than they solve:

• Don't pressure wash your roof. High-pressure water strips granules from shingles and can crack tile. If you have algae or moss (less common in San Antonio's dry climate, but it happens on north-facing slopes), use a low-pressure chemical wash applied by a professional.
• Don't seal everything with caulk. Roofing sealant and household caulk are not the same thing. Caulking over flashing gaps or cracks is a temporary fix that often traps moisture underneath and accelerates rot.
• Don't walk on a tile or steep-slope roof. Concrete and clay tiles crack under foot traffic. If your roof is tile or has a pitch steeper than about 6:12, leave the inspection to someone with the right equipment and insurance.

The Professional Inspection: When to Call

If your roof is more than 10 years old, or if you know your area got hit by hail or high winds this year, a professional fall inspection is worth every minute. A good inspector will check the full system — decking, underlayment, flashing, ventilation, and material condition — not just look at shingles from a ladder. We offer a free roof inspection that covers all of this, with photos and a written report you can keep for your records or share with your insurance company.

Fall maintenance isn't glamorous, and most of it isn't expensive. But the problems it prevents — emergency leak repairs during a cold front, denied insurance claims because damage went unreported, premature roof failure from neglected ventilation — those are expensive. Block out a Saturday this October, work through this list, and call a professional for anything you can't safely evaluate yourself. Your roof earned it after another San Antonio summer.
