Roof and Leak Repair in League City, TX

Most leaks on League City houses start at a joint, not in the middle of a slope: where a first-floor roof meets a second-story wall, where two slopes form a valley, where a vent pipe comes through. They are repairs, usually well under the 100-square-foot line TDI draws, and they are where a careful contractor earns the job.

Where the Water Gets In

Second-story walls

Step flashing behind siding where a porch or garage roof meets the wall above. When the kickout at the bottom is missing, water runs into the wall instead of the gutter.

Valleys

Two slopes shed into one channel, which carries more water than any other part of the roof and wears first.

Pipe boots

The rubber collar around a plumbing vent cracks in the sun long before the shingles around it are done.

Chimney and flue chases

Counter-flashing and the cricket behind a wide chase, if there is one.

Skylights and satellite mounts

Anything someone screwed through the roof after it was built.

Nail pops

A fastener that backs out lifts the shingle above it and opens a hole straight to the decking.

The 100-Square-Foot Line

On the Galveston County side of the lake, TDI lists “roof repairs of less than 100 square feet that don’t involve decking” as work that does not need a windstorm inspection. A new boot, a rebuilt valley, a run of step flashing: all normally inside it.

The line is crossed two ways. The repair grows past about a ten-by-ten area, or it involves decking, because the rot under a long-running leak has to come out. At that point the repair is inspected like a re-roof. A contractor should tell you before opening the roof which side of the line the job is likely to land on, and again once the decking is visible.

The windstorm inspection applies in League City, Friendswood south of Clear Creek, Dickinson, Kemah, Clear Lake Shores, Bacliff, San Leon, Santa Fe and Seabrook. It does not apply in Clear Lake City, Nassau Bay, Webster, El Lago or Taylor Lake Village. The county line page has the table.

Finding the Leak Before Fixing It

The stain on the ceiling is rarely under the hole. Water enters at the flashing, runs down the top of the decking or along a rafter, and drips where gravity finally wins. A good leak repair starts in the attic with a flashlight on a dry day, follows the staining back uphill, and only then goes on the roof. Skipping the attic is how a homeowner pays for the same repair twice.

Questions on This Job

  1. Is a leak repair a warranty issue on a newer roof?

    Possibly, if it is a workmanship defect inside the installer’s warranty period. Find the paperwork before calling anyone else; a third party’s repair can void it.

  2. Can a leak be fixed in the rain?

    It can be tarped. The permanent repair waits for dry decking.

  3. Does replacing one pipe boot need a windstorm inspection?

    No. It is far under the 100-square-foot line and does not involve decking.
