Brazoria County Windstorm Inspection & WPI-8 Certification

Quick Answer

Brazoria County is a Tier 1 coastal county — much of it, including Pearland, Alvin, Angleton, Lake Jackson, and Freeport, lies in TDI’s designated catastrophe area. New roofs, additions, and remodels there generally require TDI windstorm certification for TWIA insurance. Our licensed engineers perform WPI-8 and WPI-8E inspections across the county.

Where certification is required in Brazoria County

Brazoria County sits fully in the Tier 1 coastal band, and TDI’s designated catastrophe area covers most of it — including the Pearland corridor, Alvin, Angleton, Lake Jackson, Freeport, and the surrounding communities. Because the designated-area boundary is confirmed property by property, we verify your exact address against TDI records before you commit to anything. In practice: if your Brazoria County property needs TWIA windstorm and hail insurance, it needs a certificate.

Services for Brazoria County homeowners

For property owners we handle:

Re-roof certification — WPI-8 inspections at dry-in and fastener stages so your new roof is insurable the day it is finished.
Additions and remodels — plan review and staged inspections for anything that changes the structure.
Retroactive WPI-8E — for homes whose finished work was never certified, including at point of sale.
Pre-listing certificate checks — confirm what is on file with TDI before you list, not during the option period.

Services for Brazoria County contractors

Roofers and remodelers working Pearland, Alvin, and the county’s coastal half lose referrals when a project cannot be insured. We keep your jobs on schedule: pre-season appointment setup so WPI-1 paperwork is ready before the first tear-off, inspections scheduled around your build sequence, and rush service when an adjuster or closing date demands it. Repeat contractors get priority scheduling across all their active projects.

Scheduling and pricing

Residential re-roof certification starts at $500 plus about $0.12 per square foot; additions and new construction scale from there.
