    OUR ENGINEER INSPECTS EVERY NEW ROOF

    The Texas Gulf Coast is often hit with windstorm damage from hurricanes and other storms that can cause high winds and flooding. That’s why the State of Texas has established codes and building requirements that are designed to protect these areas from extensive damage caused by these extreme weather events.

    They maintain a Windstorm Insurance Fund for the fourteen counties for which major insurance companies don’t provide. But, before they can buy a policy through this program, they must have a certificate of compliance that verifies their property’s compliance with any applicable building codes related to its ability to withstand high winds and hail.  There are many, specific requirements for how a windstorm certified roof is installed.  Don’t worry though, at Bayfront Roofing, we take care of the entire process.

    Texas Windstorm Requirements for Roofs

    Here are the Texas windstorm certification requirements for roofs with asphalt shingles:

    • They must be fastened to roof decks that have been solidly sheathed.
    • They must be used on roof decks with a slope of at least 2 units vertical in 12 units horizontal (2:12) and up to 4 units vertical in 12 units horizontal (4:12).
    • They must be installed with fasteners that aren’t overdriven or crooked.
    • They must be tested according to ATSM D 3161, Class F. The wrappers must also have a label that indicates compliance with these standards.
    • They must be installed according to the manufacturer’s installation instructions.

    For the roof deck sheathing, the Texas windstorm requirements are as follows:

    • It must have a minimum of 7/16” OSB (14/32” plywood).
    • It must be nailed 4” o.c. edges and 6” o.c. edges in field. For gable ends the rafter and fly bang are considered edges.
    • The fasteners being used must be at least 8d common (0.131” x 2.5”).

    The windstorm requirements for the roof underlayment include the following:

    • Slopes that are greater than 4:12 must have a layer of felt that has been fastened with corrosion-resistant fasteners.
    • Slopes that are greater than 2:12 and less than 4:12 must have half-lapped felt that has been fastened with corrosion-resistant fasteners.
    • Any metal drip edge must be fastened 10” o.c.

    You must fill out an application for Certificate of Compliance and submit it to Coastal Building Inspections before you can start construction. Inspectors are then required to provide a 24-hour notice before the inspection, which must be performed during the installation process. We take care of the entire process of permitting, inspecting and issuing your windstorm certificate.
