WPI-8 versus WPI-8E
According to TDI, a WPI-8 is issued for qualifying work inspected during construction. A WPI-8E is issued for completed construction after a Texas licensed professional engineer evaluates the work and submits the required documentation. A completed-work review can be more difficult and may cost more, which is why planning the inspection early matters.
Does every repair need one?
No. The address and scope control the answer. TDI says most new construction, roof replacements, major repairs, and other alterations in designated areas require an inspection. Its examples of work that does not include a roof repair smaller than 100 square feet when decking is not involved. Do not assume that example covers a larger or structural repair.
Questions to settle before signing a roof proposal
- Is this property in the designated catastrophe area?
- Does this exact roof scope require a windstorm inspection?
- Who will apply before work begins and coordinate the inspector?
- Who will provide the certificate number or a copy after approval?
Keep the written scope, inspection information, and certificate together. If you already have a roof but cannot locate a certificate, use TDI’s public lookup before assuming one was never issued.
