What Katy home ages and hail records mean for repairs
Half of the homes in Katy were built before 2003 (U.S. Census Bureau, American Community Survey 2020-2024). Many original roofs on those homes have now been through more than 20 Texas summers. At that age, sealant strips, pipe boots and flashing tend to give out before the shingles themselves do.
Hail adds a second risk. NOAA's Storm Prediction Center logged 20 hail reports within 10 miles of Katy from 2015 through 2024, and 6 of them were 1.75 inches or larger. A hit like that can crack the shingle mat without a drip that same week. Water finds the crack later, often in a heavy rain months after the storm. Our guide on why roof damage may not cause an immediate leak explains the delay.
Where Katy roofs usually start leaking
Pipe boots
The rubber collar around plumbing vents dries out and splits. Water runs down the pipe and shows up as a stain near a bathroom or the kitchen.
Wall flashing
Where a roof meets a second-story wall, loose or rusted flashing lets wind-driven rain slip behind the siding.
Valleys
Two roof planes send their water into one channel. Worn or badly cut shingles in a valley are the first to leak in a hard downpour.
Lifted shingles
Strong gusts break the seal strip. The shingle may lie flat again, but it no longer sheds water the way it should.
Vents and skylights
Cracked housings and failed sealant around openings cause slow drips that are hard to trace from inside.
What to do the day you find a leak
Protect the inside
Move furniture, catch the water and take photos of the ceiling and any wet insulation you can see.
Note when it drips
A leak that shows only in heavy rain points to a different cause than one that shows every time. See why a roof leaks only in heavy rain.
Stay off the roof
Wet shingles are slick. Look from the ground or the attic and leave the climb to a crew with fall protection. If water is pouring in, emergency roof repair can cover it first.
Fix the source, not the stain
Water can run along rafters before it drips. A proper repair traces it back to the entry point and fixes that spot.
Get it in writing
A written estimate should say what will be replaced and why, with photos of the damage.
Signs a repair may not be enough
Leaks in more than one room at the same time.
Granules piling up in the gutters and bare spots on many shingles.
Soft or sagging decking seen from the attic.
Repeated repairs on the same section in a short time.
Hail bruises spread across several roof planes after a large storm.
Repair now, plan ahead
A good repair buys time. It does not reset the age of the roof. If your home still has its first roof, use the repair visit to get an honest read on how much life is left. Our article on roof repair vs. replacement lays out the trade-offs, and roof replacement in Katy covers what comes next if the answer is a new roof.

Frequently Asked Questions
How can I tell if a roof leak in Katy came from hail?
Hail leaves round bruises or cracks on shingles, dents on vents and gutters, and loose granules. A leak from a worn pipe boot or flashing does not show those marks. An inspection with photos tells you which one you have, which matters if you plan to talk to your insurance company.
Can one part of the roof be repaired without redoing all of it?
Often, yes. Damaged shingles, flashing and pipe boots can be replaced on their own. New shingles may not match the old color exactly, especially on an older roof, and the repair only lasts as long as the roof around it holds up.
Should I wait for a dry day to call about a leak?
No. Water that gets past the roof soaks insulation and decking and can lead to mold. Call as soon as you see a stain or a drip. A temporary cover can keep water out until the permanent repair is done on a dry day.
