Roof Replacement to Windstorm Code in League City, TX

A League City re-roof has two audiences: the homeowner who lives under it and the inspector who has to see it before the shingles hide the work. Built to the code TDI adopted for certification from April 1, 2026, inspected while it is open, and certified by the Department, it keeps the house eligible for TWIA. Built any other way, it may not.

What Is Different From the Roof Coming Off

Plenty of League City roofs being replaced now went on in the 2000s. TDI’s downloads page lists its Texas revisions to the 2006 International Residential Code as effective January 1, 2008, and the 2003 edition from January 1, 2005. A re-roof today is certified to the 2024 International Residential Code.

In practice the differences show up in the parts nobody sees: how the decking is fastened to the rafters and at what spacing, the underlayment and how it is attached, and the edge details at the eaves and rakes where wind gets its first grip. A contractor quoting a Galveston County re-roof should be able to say which of those change on your house, and should not be quoting “same as what was there.”

The Order of Work

  1. Tear-off to the decking. Damaged or delaminated sheets are replaced; on older houses the edges are where they usually fail.
  2. Deck fastening checked and brought to code. This is the step the inspector most needs to see, and the one that is gone from view by lunchtime.
  3. Underlayment, drip edge and starter. Installed to the product’s wind-rated method and the code.
  4. Shingles or panels. With the fastener count the manufacturer requires for the high-wind rating, which is usually more than the standard pattern.
  5. Inspection and certificate. A TDI windstorm inspector or an appointed Texas licensed professional engineer inspects while work is underway; TDI issues the WPI-8.

Who Arranges the Inspector

Ask before signing. Some contractors book an appointed engineer as a matter of course and build the inspection visits into the schedule; others leave it to the homeowner. Either can work. What does not work is discovering after the roof is on that nobody saw the decking, because the fallback is a WPI-8-E from an engineer inspecting completed work, which TDI says can cost more and is not guaranteed.

TDI keeps a list of appointed engineers on its windstorm site and takes calls at 800-248-6032.

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.

Questions on This Job

  1. How long does a League City re-roof take?

    A typical two-story house is a day or two of work on the roof itself, weather allowing. The inspection visits are timed around the decking and underlayment stages, not at the end.

  2. Does a re-roof need a certificate if the old roof had one?

    Yes. The certificate covers the work it inspected. New work is inspected on its own.

  3. I am in Webster. Does this page apply?

    The workmanship does; the certificate does not. Webster is in Harris County west of SH 146, outside TWIA, so there is no windstorm inspection. The city permit rule still applies.
