Last updated October 29, 2026Key things to know
Damaged or missing shingles
Wind and age can crack or lift shingles, letting water reach the underlayment.
Failed flashing
Metal flashing around chimneys, walls and valleys can rust, lift or lose its seal.
Cracked pipe boots
Rubber boots around vent pipes crack in the sun and let water run down the pipe.
Clogged gutters and valleys
Debris makes water back up under the shingles at the roof edge.
Worn sealant
Sealants dry out and crack over time, especially in Houston’s heat.
An aging roof
When shingles are worn out, leaks tend to appear in several places.

Common questions
Why does my roof only leak in heavy rain?
Heavy or wind-driven rain pushes water into small gaps in flashing or damaged shingles that stay dry in light rain.
Is a small roof leak an emergency?
It may not feel urgent, but even small leaks can soak insulation and decking and cause mold. Get it checked soon.
How long can I wait before fixing a leak?
The sooner the better. A temporary tarp can protect your home until a permanent repair is done.
