The short answer
What Mammoth Services does in Seabrook.
Mammoth Services is a commercial and industrial roofing contractor based on East NASA Parkway, along the same corridor as Seabrook. In Seabrook, Mammoth Services handles roof replacements, recovers, restoration on sound roofs, and new construction roofing, with materials and details chosen for salt air and Gulf wind.
Two sets of wind rules apply in Seabrook. The City requires a 150 mph ultimate design wind speed everywhere in town, with engineer-sealed plans for commercial work, and buildings east of SH 146 are also inside TDI’s designated catastrophe area, where TDI windstorm certification decides TWIA eligibility. Mammoth Services plans the City permit, the engineered design, and any TDI inspection together.

Two wind lines, one city
SH 146 divides the insurance map. The City’s wind rule covers everything.
In Seabrook, which side of SH 146 a building sits on matters for windstorm insurance. It does not change the City’s design wind speed.
East of SH 146
TDI includes the areas of Seabrook east of SH 146, inside city limits, in its designated catastrophe area, in the Inland I zone. For TWIA eligibility, TDI lists a WPI-8 windstorm certificate as applicable to Seabrook buildings there constructed after March 1, 1996.
Citywide, 150 mph
Seabrook’s building code amendments require construction east and west of SH 146 to meet a 150 mph ultimate design wind speed. Commercial plans and calculations are sealed by a Texas engineer on TDI’s list for high wind zones.
New TDI code basis
TDI says that starting April 1, 2026, windstorm Certificate of Compliance applications must be certified to the 2024 International Building Code or Residential Code. We confirm the current basis with the appointed inspector for each project.
Sources: Texas Department of Insurance, Harris County designated catastrophe area and Adopted Building Codes; City of Seabrook, Code of Ordinances Secs. 18-121 and 18-122 and Commercial Construction. Insurance eligibility is decided by TWIA and your insurer.
Seabrook permitting
What the City asks for on a commercial roof.
Seabrook’s Building Department reviews plans, inspects construction, issues permits, and registers contractors. New roofs and roof repairs are both on its permit list.
Plan review
The City estimates about 14 to 21 business days for commercial review. Documents go in complete, with the engineered wind design, so the clock does not restart.
Asbestos survey
The City notes that renovation or demolition of public or commercial buildings in Texas requires an asbestos survey before the building permit is approved. On older roofs we plan for that before tear-off.
Energy compliance
Seabrook enforces the 2021 International Energy Conservation Code. Its amendments (Sec. 18-359) have an approved third-party agency make the commercial energy code inspections and provide a Final Letter of Compliance when the project is complete.

Between Clear Lake and Galveston Bay
The commercial buildings of Seabrook.
Seabrook incorporated in 1961, and its master plan notes that nearly all of its commercial development sits along NASA Parkway and SH 146, apart from Old Seabrook.
Marinas, shipyards, and marine businesses
The City’s master plan counts three major marinas with more than 1,250 boat slips, and its zoning includes a marine oriented mixed use district for marinas, shipyards, and related commercial activity.
- Metal buildings, sheds, and offices near salt water
- Work planned around haul-outs, fuel docks, and yard traffic
Waterfront restaurants and hospitality
Seabrook’s waterfront districts are planned for restaurants, retail, recreational services, and hotels, with piers and boardwalks. Kitchen exhaust, rooftop equipment, and public areas below all shape the roof plan.
- Grease exhaust areas specified with compatible membranes
- Work hours set around service and guests
SH 146, NASA Parkway, and the port side
The master plan describes the SH 146 corridor as retail, services, and restaurants, and an office warehouse district near the port with direct SH 146 access. Port Houston’s Bayport Container Terminal is on Port Road, reached from SH 146.
- Retail and service roofs with tenants open below
- Office warehouse roofs with large low-slope areas and dock-side traffic

Salt air and wind
Specified for the coast, not just the code.
Code sets the minimum. Near the water, the details that fail first are metal, fasteners, and terminations, so that is where we spend the specification.
- 01
Edge metal and fasteners
Materials and finishes chosen for corrosion resistance, and attachment at edges and corners per the engineered design and manufacturer requirements.
- 02
Single-ply and multi-ply
TPO, PVC, modified bitumen, and built-up systems, matched to the building. PVC suits roofs with grease or chemical exhaust.
- 03
Metal roofs
Installation, repair, and restoration for marine, shop, and warehouse buildings, including corroded panel and fastener replacement.
- 04
Rooftop equipment
Curbs, supports, and tie-downs detailed with the mechanical scope so units stay put in high wind.

Questions
Commercial roofing in Seabrook: direct answers.
If your question is not here, call Mammoth Services at (832) 416-1566.
- 01
Is Seabrook in the TDI windstorm area?
Partly. The Texas Department of Insurance includes the areas of Seabrook east of State Highway 146, inside the city limits, in its designated catastrophe area. West of SH 146, Seabrook is outside it. The City of Seabrook’s own 150 mph wind design rule applies on both sides.
- 02
Does a commercial roof in Seabrook need a WPI-8?
A WPI-8 is TDI’s windstorm Certificate of Compliance, and TWIA uses it for insurance eligibility. TDI lists it as applicable to Seabrook buildings east of SH 146 constructed after March 1, 1996. If your Seabrook building is insured through TWIA or may be, Mammoth Services plans the TDI inspection with the roof work from the start.
- 03
What wind speed does Seabrook require for a commercial roof?
The City of Seabrook has adopted a 150 mph ultimate design wind speed for construction both east and west of SH 146, and the City’s commercial construction page asks for plans, details, and calculations sealed by a Texas engineer on TDI’s list for high wind zones.
- 04
How long does commercial plan review take in Seabrook?
The City of Seabrook estimates about 14 to 21 business days for commercial projects. Mammoth Services submits complete documents so the review is not restarted for missing items, and builds the schedule around the City’s timeline.
