A Class IV impact asphalt shingle is a type of roofing material that is designed to withstand hailstorms and other severe weather conditions. These shingles are rated based on their ability to resist impact damage from hailstones, with Class IV being the highest rating available.


Class IV impact asphalt shingles are typically made with a fiberglass mat that is coated with asphalt and granules. These shingles are designed to be thicker and more durable than standard asphalt shingles, which makes them more resistant to hail and other types of impact damage.

In addition to their impact resistance, Class IV impact asphalt shingles also offer a range of other benefits, such as improved fire resistance and a longer lifespan compared to other types of asphalt shingles. As a result, they are often used in areas that are prone to severe weather events or other types of environmental hazards.
