Step 1
Enter the attic during or right after rain. Find the wettest wood and insulation.
Water coming in? Call now
Call (619) 775-3787 right now if water is coming in. A connected contractor answers, dispatches a tech to your address, and stops the water from spreading. Houston Gulf downpours push gallons through a single gap in minutes. Waiting turns a small repair into soaked insulation, swollen decking, and mold.
Do these four things while the contractor drives to you.
- Place buckets under every active drip.
- Move electronics, documents, and furniture out of the drip path.
- Photograph stains and drips for your insurance file.
- Shut off power to any room with water near outlets or fixtures.
Stay off the roof. Wet shingles offer almost no footing in Houston humidity. A fall costs more than any leak repair. Contractors carry the gear and the liability coverage for steep, wet roofs.
The Federal Emergency Management Agency reports that one inch of water in a home can cause up to $25,000 in damage. A roof leak that runs overnight puts that inch on your attic floor and ceiling drywall. Every hour of delay raises the bill.
For damage that goes past the leak itself, see our full roof repair services. For an active drip right now, call (619) 775-3787. A contractor gets moving the minute you hang up.

Where Houston roof leaks usually start
Houston roof leaks start at flashing points, vent boots, skylights, valleys, and chimney joints. The trade publication Building Enclosure reports that nearly 90 percent of reported roof leaks occur at flashing locations such as terminations, walls, and penetrations. Roof joints fail before roof fields do.
Flashing is the sheet metal that seals every joint where the roof meets a wall, chimney, or penetration. Houston heat expands and contracts that metal every day. Sealant dries out. Nails back out. A Gulf downpour then drives rain sideways under the shingles. Humidity keeps the wood damp between storms, which feeds rot.
- Flashing seams: splits open where metal was bent over the membrane or nailed too tight to move.
- Vent boots: the rubber collar around plumbing vents. UV and Houston heat crack the rubber, then water runs straight down the pipe.
- Skylights: factory seals age and curb flashing lifts. Condensation on the glass gets blamed for leaks that start at the curb.
- Valleys: the V where two roof planes meet. Valleys carry the most water on the roof. Debris dams the flow and forces water sideways.
- Chimney joints: step flashing and counterflashing seal brick to roof. Mortar cracks, counterflashing pulls loose, and the gap opens. Read our guide to roof leaking around chimney flashing.
Check your attic after every major storm. Dark streaks on rafters and damp insulation mark the path water took. Catching a leak in the attic costs a seal. Catching it on your ceiling costs a repair plus drywall.
How a leak gets traced to its source
Contractors trace a leak by inspecting the attic first, then the roof surface up-slope from the drip point. The drip point is rarely the entry point. Water rides along rafters and decking, then drops through the nearest gap. A stain above your hallway light often starts at a vent boot 10 feet up-slope.
The tracing process runs in four steps.
Step 2
Trace stains up-slope. Water flows downhill, so the entry sits above the highest wet spot.
Step 3
Inspect the roof surface above that point. Check flashings, boots, and shingle courses for gaps, cracks, and lifted edges.
Step 4
Confirm with a controlled water test. A tech runs water over one suspect area at a time while a helper watches the attic.
On a typical 20-square Houston ranch roof (2,000 square feet; one roofing square equals 100 square feet), the suspect zone usually sits 3 to 10 feet up-slope of the interior stain. Skipping the trace and sealing the stain spot is why repairs fail and leaks return.

What leak repair involves
Leak repair involves sealing the entry point, replacing failed flashing, replacing cracked vent boots, and rebuilding shingle courses around the entry.
- Sealant work: roofing cement and polyurethane sealant close small gaps at flashing edges and nail heads.
- Flashing replacement: the tech removes shingles around the joint, installs new step or counter flashing, and re-shingles over it.
- Vent boot replacement: the old boot comes off the pipe and a new rubber-and-aluminum boot goes on. See our guide to roof vent boot replacement for the full process.
- Shingle work around the entry: cracked or lifted shingles around the repair get replaced so the patch blends into the field.
A vent boot is the rubber collar that seals a plumbing vent where it exits the roof. Boot rubber hardens in Houston sun in about 7 to 10 years. Replacing the boot takes under an hour once the tech is on the roof.
Minor leak repairs in Houston run $300 to $800. Flashing or boot replacement runs $400 to $1,200. Repairs with deck damage run $1,500 to $3,000 or more. Pitch, material, and access move the final number. Call (619) 775-3787 and a contractor prices your exact repair on your roof.
Leak repair questions, answered
The most common leak questions cover cost, timing, and whether the fix will hold. Quick answers below. They cover the roof leak repair Houston homeowners ask for most: what a roof leak does inside a house, how a tech will find a roof leak, when flashing repair solves the problem, and why you should call now instead of waiting..
For stains without active dripping, read our guide to a water stain on your ceiling from a roof leak.
Can a roof leak wait, or does it need fixing right away?+
Fix it right away. Small leak repairs run $300 to $800. Waiting lets water soak the decking and drywall, which pushes the job into the $1,500 to $3,000 range. Mold starts on wet drywall within 24 to 48 hours. Call (619) 775-3787 now for same-day dispatch.
Will the leak come back after the repair?+
A repair at the true entry point holds for years. Callbacks happen when someone seals the stain spot instead of the entry point up-slope. Ask the contractor to show you the entry point from the attic before work starts. Call (619) 775-3787 and the repair gets traced first, sealed once.
Does homeowners insurance cover a sudden roof leak?+
Most HO-3 policies cover sudden and accidental water damage, including interior damage from a storm-driven roof leak. Gradual leaks from neglected maintenance get denied. The Insurance Information Institute's 2024 data lists water damage as the second most common homeowners claim category, with about 1 in 60 insured homes filing a water damage or freezing claim each year. Photograph everything, call your insurer early, and call (619) 775-3787 to get the roof sealed before the next rain.
How fast can a contractor get to my house?+
Connected contractors dispatch same day for active leaks across the Houston metro, usually within hours. Night and weekend calls get answered. Water inside your home right now means a same-day dispatch. Call (619) 775-3787.
