San Antonio homes and roof age
Half of the homes in San Antonio were built before 1985 (U.S. Census Bureau, American Community Survey 2020-2024). That means a large share of houses are 41 years old or more. Many have had at least one reroof, but roofs replaced years ago are now reaching the age when shingles curl, flashing loosens and sealant around vents gives out.
The same survey shows that about 52 percent of homes in the city are owner occupied. If you own and live in the house, the inspection is your planning tool. If you rent it out, it protects the property between tenants and helps you schedule repairs before a complaint comes in.
Large hail adds to the wear. It was reported near the city in 2016, 2020, 2021 and 2024, and a roof that came through one of those storms may carry bruises that never leaked. An inspection is the only way to know which roofs were touched and which were spared.
What happens during an inspection
Ground and perimeter
The inspector checks gutters, fascia, soffits and the overall shape of the roof for sagging.
Roof surface
Each slope is walked when safe. Shingles, tiles or panels are checked for wear, hail hits, lifting and missing pieces.
Flashing and penetrations
Chimneys, walls, skylights, pipes and vents are checked, since most leaks start there. See roof leaks around chimneys and vents.
Attic
Stains, damp insulation, daylight at the decking and ventilation are checked from below.
Report and estimate
You get photos and a written estimate for any needed work. Estimates from GemSco are free.
Three reasons San Antonio owners call for one
After a hailstorm
NOAA's Storm Prediction Center logged 48 reports of hail 1.75 inches or larger within 10 miles of San Antonio from 2015 through 2024, including 4.5-inch hail on April 12, 2016.
Buying or selling
A roof report gives buyers and sellers a clear starting point and avoids surprises late in the deal.
Age and wear
A roof past its middle years benefits from a yearly look so repairs can be planned instead of rushed.
Signs you should not wait for a yearly check
A water stain on a ceiling or wall, even a small one.
Shingles in the yard after wind.
Granules collecting in gutters or at downspout outlets.
Shingles that curl, crack or look darker in patches. See why shingles curl, crack or fall off.
Musty smells or higher humidity in the attic.
Turning findings into a plan
Most reports fall into one of three outcomes. The roof is sound and needs nothing for now. The roof needs a targeted fix, which our roof repair page for San Antonio covers. Or the roof has reached the point where repairs no longer make sense, and it is time to plan a replacement. In each case, the photos in the report give you a baseline to compare after the next storm.

Frequently Asked Questions
How long does a roof inspection take?
It depends on the size, pitch and access of the roof and whether the attic can be reached. A typical single-family home takes a short visit rather than a full day. Steep or tile roofs can take longer because the inspector moves more carefully to avoid breaking anything.
Is a roof inspection the same as a home inspection?
No. A general home inspector looks at the whole house and may only view the roof from the ground or a ladder. A roofer focuses on the roof system: shingles, flashing, decking, ventilation and drainage, and can tell you what a repair or replacement would involve.
Do tile roofs in San Antonio need different inspections?
Tile roofs are checked for cracked, slipped or missing tiles and for the condition of the underlayment beneath. Tiles can break when walked on, so the inspector chooses footing carefully. The underlayment often wears out before the tiles do, which is why it gets special attention.
