What Are High-Wind Rated Shingles?

High-wind rated shingles are asphalt shingles tested and certified to resist wind speeds above standard ratings. While regular shingles are rated up to 60–90 mph, high-performance models can withstand up to 130–150+ mph when installed properly.

These shingles:

  • Use stronger adhesives and thicker materials

  • Often feature reinforced nailing zones

  • Must be installed with enhanced fastening methods (like six nails per shingle)

Why It Matters in Colorado

Colorado’s Front Range and mountain corridor frequently see wind gusts of 80–100 mph, especially in cities like Boulder, Colorado Springs, and Westminster. Homes with standard shingles are at real risk of shingle blow-off, water damage, and premature roof failure.

The Insurance Institute for Business & Home Safety (IBHS) has confirmed that homes using impact- and wind-rated shingles perform far better after windstorms.

How Are Shingles Rated for Wind?

Wind resistance is tested under ASTM D3161 and ASTM D7158:

  • ASTM D3161: Class F = rated to 110 mph

  • ASTM D7158: Class H = rated to 150 mph (most demanding)

To meet the top rating (Class H), shingles must be nailed correctly and fully sealed. Under these conditions, they resist hurricane-force winds.

Best Practices for Installation

High-wind rated shingles are only as strong as their installation. Key requirements:

  • Minimum six nails per shingle

  • Nailing into decking (not over old layers)

  • Use of starter strips and proper edge sealing

  • Avoiding overlay installations (old shingles left underneath)

Shingle manufacturers like Owens Corning, Malarkey, and IKO all emphasize following their specific wind uplift guidelines.

Should You Upgrade?

If you're re-roofing or building new in Colorado, choosing high-wind rated shingles is a smart, low-cost way to protect your investment. Many insurance companies even offer premium discounts when Class F or H shingles are installed.

FAQs

What wind rating should shingles have in Colorado?
Look for ASTM D7158 Class H shingles — rated to 150 mph. These perform best under severe wind gusts common in Colorado.

How many nails should be used per shingle in a high-wind area?
Six nails per shingle are recommended. Four nails won’t meet high-wind uplift requirements in most cases.

Are high-wind shingles more expensive?
Only slightly. The cost difference is minimal compared to the potential for damage. Most roofers carry Class F or Class H options as standard.
