Understanding Class H Shingles
What Makes a Shingle Class H
Class H shingles have a reputation for being some of the toughest on the market, and it’s not by chance. The designation comes from rigorous testing that proves they can withstand gusts up to 150 miles per hour—wind speeds associated with serious storm conditions.
These shingles are engineered with stronger adhesives, reinforced nailing zones, and layered construction that keeps them locked in place. They’re not just assembled; every detail matters, right down to the way they adhere to the roof deck. For homeowners tired of storm repairs, Class H shingles feel like an investment in peace of mind.
Think of them like upgrading from standard car tires to heavy-duty off-road ones. You don’t always need the toughness, but when conditions turn rough, you’re glad you made the choice.

How Shingles Are Tested for Wind Resistance
Before earning the Class H label, shingles must pass hurricane-level wind simulations. Machines replicate uplift pressure, essentially trying to rip the shingles from the roof deck.
If the sealant strip holds and the shingles don’t budge, they qualify. Testing involves multiple angles of force, weeks of preparation, and worst-case storm scenarios. The process ensures homeowners aren’t just relying on marketing claims—the shingles have been pushed to their limits and passed.

Why Manufacturers Created Class H Ratings
The rating emerged from a real need in storm-prone regions. Homeowners were frustrated with shingles tearing off in hurricanes and insurers were overwhelmed by claims. Class H provided a standardized benchmark, giving consumers confidence and bringing consistency to the industry.
This benchmark also pushed competitors to improve, raising overall roofing quality across the market.
