Windstorm Engineering

Most new construction, roof replacements, major repairs, and other alterations require an inspection and certificate of compliance. During the inspection process, we will verify that all construction is in compliance with TDI product evaluations, manufacturers approved installation and/or engineered construction drawings

Our Windstorm Engineering Services

As of June 1, 2020, all new and ongoing construction, roof replacements, major repairs, and other alterations must be inspected by an engineer appointed by TDI (Texas Department of Insurance) for a TDI WPI-8.  Any completed construction project can be inspected a State of Texas registered engineer to receive a TDI WPI-8.

As of September 1,2020, all new construction must meet the minimum requirements of IBC or IRC 18 to receive a TDI WPI-8.

Who's Affected

TDI has designated the 14 coastal counties and some areas of Harris County to be in the catastrophe area.  Homeowners in these areas may not be able to obtain private insurance that covers windstorm and hail damage and must get coverage through TWIA.

In order to purchase a TWIA policy, most homes and properties must have a certificate of compliance verifying that the structure meets applicable building codes and can withstand high winds and hail.

For alterations like a re-roof (non-shingle), re-sides, new windows, new doors, new skylights etc., we will inspect that these products are installed in accordance with TDI product evaluations.

For new construction and additions, windstorm/structural engineering and design must be completed for all projects within the designated catastrophe area. Lynn Engineering will engineer your project to meet the design requirements of the code. This must include a Windstorm Compliant Plan and Foundation Plan.
