It decides whether the roof needs a windstorm certificate. Start there, then pick the job.
Creased tabs, a torn ridge, a missing course, and whether it is repair-sized or certificate-sized.
Built to the code TDI applies now, not the one the builder used.
Flashing at second-story walls, boots, valleys, the 100-square-foot line.
Cracked planks, open butt joints and failed caulk on newer houses.
Swollen, soft lap siding on older Clear Lake houses.
Torn sections, trim and fascia pulled loose by a gust.
Also: architectural shingle, standing-seam metal, inspections before a sale and gutters and downspouts.
An EF3 tornado crossed southeast Harris County. The National Weather Service survey put its peak winds at an estimated 140 mph along an 18.7-mile path, up to 1,000 yards wide, that ran from near Pearland at 2:15 p.m. to near Baytown at 2:50 p.m. Most of the damage was in Pasadena and Deer Park, a few miles north of Clear Lake.
It is the reason this site talks about wind before it talks about shingles. Eighteen months later, Hurricane Beryl came ashore near Matagorda as a Category 1, and NWS Houston logged gusts of 52 mph at League City, 73 mph at Webster and 75 mph at Clear Lake Park on the morning of July 8, 2024.
On the Galveston County side, the inspector sees the decking, the fasteners and the underlayment before the shingles cover them, or an engineer has to certify it all afterward. On most of the Harris side, the same roof goes on with a city permit and nothing more. These are the details that separate the two.
A re-roof, or a repair to a significant portion of a roof, is built to TDI’s adopted windstorm code and inspected for a certificate of compliance.
No windstorm certificate for most of Clear Lake. Seabrook is the exception: TDI lists it among the Harris County cities east of the highway that are inside the program.
Friendswood gets both columns because the county line runs through it. The county line page goes through the boundary street by street where the sources allow, and says where they do not.
Maybe not. The Texas Department of Insurance lists roof repairs of less than 100 square feet that do not involve decking among the jobs that do not need a windstorm inspection. Past that size, or once decking is replaced, the repair is inspected like a re-roof. TWIA’s own wording is “repairing a significant portion of a roof.”
Because it does not. TWIA covers Harris County only east of State Highway 146, and TDI’s program names the Harris County cities it reaches: La Porte, Morgan’s Point, Pasadena, Seabrook and Shoreacres. Nassau Bay, Webster, El Lago, Taylor Lake Village and Clear Lake City are not among them.
No. The contractor builds to the code. A TDI windstorm inspector or a TDI-appointed Texas licensed professional engineer inspects the work, and the certificate comes from the Texas Department of Insurance. A roofer cannot issue one.
This site’s storm pages are about wind: Gulf systems, the tornadoes they spin off, and the gusts behind a front. It does not quote a hail record for Galveston County, because none has been pulled from NOAA’s storm database for this site. If hail is what you have, the inspection page covers it the same way.
Name the city or subdivision and what you are seeing. A local contractor who knows which rule applies to your address calls back.
