Important Notice From the Texas Department of Insurance

Don’t Be Caught Without Windstorm Insurance Coverage! - After the recent catastrophic hurricane seasons and with many people still trying to put their homes and lives back together, is your home covered for hurricane or other windstorm damage so you won’t be the next victim? If you live in one of the Texas' coastal counties, then you know how devastating and costly a storm can be. Don’t let an unexpected storm, like Rita, cost you. With the latest and most effective wind resistant construction, you will have a stronger structure and a better opportunity to obtain windstorm and hail insurance coverage through the Texas Windstorm Insurance Association or the voluntary market.

For more information about obtaining or maintaining windstorm insurance coverage when you build, remodel, add-on, repair or re-roof a structure, the Texas Department of Insurance (TDI) encourages you to contact your insurance agent or the Windstorm Inspection Division of TDI at 800-248-6032 or via e-mail.
