Roof Shingle Wind Resistance Ratings

A quality shingle roof should be able to protect your home against extreme weather conditions. From strong winds to heavy storms, you need to know that your household is protected.

When it comes time to select new shingles for your roof replacement, you may notice that they’re assigned a wind rating. But what does this rating mean? Follow this useful guide to help you select the right shingles for your asphalt roof replacement.

What Does a Shingle Wind Rating Mean?

Asphalt shingles are designed to protect a home through strong weather conditions. To prove their durability, they’re tested to meet the standards of the ASTM International, which provides worldwide standardization for quality products, including roof replacement materials. As shingles are tested by the ASTM International, they’re given a rating based on which wind speeds they can withstand.

ASTM D3161: The Standard Test Method for Wind Resistance of Steep Slope Roofing Products (Fan-Induced Method)

The ASTM D3161 tests how well products work against wind speeds produced by a fan. As class ratings go up, so do their ability to withstand higher wind speeds. These ratings include:

  • Class A Shingles Withstood 60 MPH Speeds
  • Class D Shingles Withstood 90 MPH Speeds
  • Class F Shingles Withstood 110 MPH Speeds

ASTM D7158: The Standard Test Method for Wind Resistance of Sealed Asphalt Shingles (Uplift Force/Uplift Resistance Method)

The ASTM D7158 tests how well products can withstand uplift forces. Just like the previous test, these ratings go up as they withstand higher wind speeds. These wind ratings include:

  • Class D Shingles Can Withstand Wind Uplift at 90 MPH
  • Class G Shingles Can Withstand Wind Uplift at 120 MPH
  • Class H Shingles Can Withstand Wind Uplift at 150 MPH
