Beaumont Roofing Same Three Letters, Three Different Documents
If you've owned a house in Jefferson County long enough to have re-roofed it, you've probably heard the term WPI-8 tossed around like everyone already knows what it means. Most people don't, and the confusion usually starts because there isn't just one WPI-8 — there are three versions of it, and which one applies to your house depends on when the roof went on and who signed off on it.
A WPI-8 is the Windstorm Certificate of Compliance. It's the document that tells TWIA — the Texas Windstorm Insurance Association — that a roof, or a whole structure, was built or repaired to the windstorm construction requirements TDI adopted for first-tier catastrophe counties, which includes Beaumont, Port Arthur, Nederland, Port Neches and Groves. Vidor, Orange and Lumberton sit outside that first-tier list, so this whole certificate system doesn't apply to those addresses the way it does here.
The letter at the end tells you who issued it and under what circumstances:
- WPI-8 — the certificate TDI issues for new and ongoing improvements, from a full re-roof down to a significant roof or siding repair, after a TDI-appointed inspector or a Texas-licensed engineer has inspected the work.
- WPI-8-C — a certificate issued directly by TWIA rather than TDI. TWIA issued these between January 1, 2017 and May 31, 2020. Those certificates carry the TWIA name.
- WPI-8-E — the certificate TDI issues for a completed improvement, on a Texas-licensed engineer's certification that it was built to the specification.
Why the Issuer Changed in 2020
Since June 1, 2020, every certificate — regardless of the letter — comes from TDI, not TWIA. TWIA stopped issuing its own C-series certificates as of that date, which means any roof completed on or after June 1, 2020 will have a TDI-issued document, even if the property is also TWIA-covered. This matters when you're trying to track down paperwork for an older re-roof: a WPI-8-C from 2017–2020 is in TWIA's lookup; everything TDI issued, before or after 2020, is in TDI's.
A West End House, Worked Through
Take a fairly typical example: a brick-veneer house in Beaumont's West End, re-roofed in 2019 after storm damage, sold to a new owner in 2023. The new owner needs proof of the certificate for their TWIA coverage renewal and doesn't know where to start. Here's the sequence that actually works:
- Check the date first. For a roof from 2017 to May 2020, check both: TDI's search for a WPI-8 issued during construction, and TWIA's lookup for a WPI-8-C.
- From June 1, 2020 on, use TDI's certificate search only.
- If neither search turns up a match, TDI also answers certificate questions by phone at 800-248-6032, option 3.
- If no certificate exists at all — not lost, just never issued — that's a different problem, and usually means the original work wasn't inspected under the windstorm program to begin with. A roof inspection and certificate check can confirm whether the roof itself would still qualify.
For a 2019 roof like that one, both databases are worth checking. Not every address is that simple; older homes near Calder Avenue or Old Town, re-roofed in stages or by more than one contractor over the years, sometimes have partial records or none.
When the Certificate Can't Be Issued As-Is
Occasionally an inspector or engineer looks at a roof and can't certify it in its current condition — a repair that wasn't sealed to spec, decking that doesn't meet nail-hold requirements, or flashing details that don't match the adopted standards. In that case, the honest answer is that it needs work before a WPI-8 of any letter can be issued, not that the paperwork is simply missing. A re-roof built to windstorm specs from the outset avoids that gap entirely, since the certificate follows the completed work as part of the process rather than being chased down after the fact.
If you're not sure which certificate applies to your house, or you've moved to Beaumont and inherited a roof with no visible paperwork, our Beaumont service area page is a reasonable place to start sorting out what you actually have.
The takeaway: know your re-roof date first, because it tells you whether to search TWIA or TDI, and a missing certificate almost always means a phone call to TDI comes before it means a new roof.
