Houston Roof Repair for Leaks, Wind and Wear
Houston roofs fail from water more than from anything else. Most problems start small, at a seam or a vent, and are cheap to fix if they are caught early.

Signs your roof needs a repair, not a new roof
A single ceiling stain that grows after heavy rain
A few shingles missing or lifted after a windy storm
Cracked rubber boots around plumbing vents
Rusted or loose flashing at a chimney, wall or skylight
Granules piling up at the bottom of one downspout
Gutters that overflow at the same corner every storm
What wears down roofs in Houston
Heavy rain is the stress test. Water finds any gap at a flashing joint, a nail pop or a cracked vent boot, and it can soak decking and insulation long before a stain shows inside. Summer heat dries out sealant and rubber, and strong wind lifts shingle edges that have lost their bond.
Hail matters too, though less than in North Texas. NOAA's Storm Prediction Center logged 40 hail reports within 10 miles of Houston from 2015 through 2024, nine of them 1.75 inches or larger. If a storm just came through, start with our Houston hail damage page.
Repairs we handle most often
Leak tracing
Water often enters feet away from the stain you see. We follow it back to the real entry point. More on roof leaks.
Flashing
Resealing or replacing flashing at chimneys, walls, valleys and skylights.
Vent boots
Swapping cracked pipe boots, one of the most common leak sources on older roofs.
Shingle replacement
Replacing missing or broken shingles and matching them as closely as the existing roof allows.
Gutters
Re-hanging and resealing gutters so water leaves the roof edge. See gutter repair.
Flat sections
Patching low-slope areas over porches and additions where water sits. See flat roof repair.
From your call to a dry roof
Tell us what you see
Where the stain is, when it shows up and what the weather was. That narrows the search.
Inspection
We check the roof surface, the flashing and the attic side wherever we can reach it.
Photos and a written estimate
You see the cause and the price to fix it before any work starts.
Repair
We make the repair and clear the debris. If the roof is beyond repair, the estimate says so plainly.
When repair stops making sense
Half of the homes in Houston were built before 1982 (U.S. Census Bureau, American Community Survey 2020-2024). On a house that age a repair can be the right move, but not forever. If we find soft decking across a slope or brittle shingles everywhere, we show you the photos and price a roof replacement in Houston as an option, not a push.
With 58 percent of Houston homes renter occupied, many calls come from landlords whose tenants mention a leak only once water reaches the ceiling. Fixing the boot or flashing at that point is still cheaper than drywall. See our general roof repair service and our page on roofing in Houston.
Frequently Asked Questions
Can you repair just one section of my roof?
Yes, when the rest of the roof is sound. Leaks around flashing, vents and a few missing shingles are usually local problems. We match new shingles as closely as we can, but older shingles fade, so a perfect color match is not always possible. The written estimate notes that before any work begins.
Why does my roof leak only in heavy rain?
Light rain runs off normally, but heavy, wind-driven rain pushes water sideways under shingle edges and into weak flashing joints. Gutters that overflow can also back water under the roof edge. Those leaks are hard to find in dry weather, so tell us what the weather was like when the stain appeared.
What if water is coming in right now?
Call and tell us it is urgent. A temporary cover such as a tarp can limit damage until a permanent repair is made. Our emergency roof repair page explains what to do in the meantime. Take photos of the roof and the interior damage before cleanup, and note the date the leak started.
Is a roof repair estimate free?
Yes. GemSco gives free estimates. After the inspection you get photos of the problem and a written estimate for the repair, so you can decide without pressure. If a repair will not hold because the roof is too worn, the estimate explains why and lists the options side by side.
