A wind rating describes the wind-resistance performance associated with a roofing product, usually based on testing and manufacturer warranty terms.
Why It Matters
Wind rating helps homeowners compare products, but the rating only matters when the shingles are installed correctly and the roof system is in proper condition.
Common Problems
Common issues include assuming the rating is an absolute guarantee, ignoring fastening requirements, installing on poor decking, or missing starter and edge details. Homeowners may also misunderstand wind speed itself. A reported 50 mph wind does not mean every part of the roof only experiences a simple 50 mph force. Roof corners, eaves, rakes, ridges, height, exposure, and wind direction can concentrate uplift pressures so certain areas experience much harsher forces than the number in a weather report suggests.
Building Codes & Industry Standards
Wind performance may be tied to manufacturer instructions, local design wind requirements, and recognized testing standards for asphalt shingles.
