How is a Class 4 Shingle Rated?

The impact resistance of a Class 4 shingle is determined by performing a test that simulates hailstones hitting the roof at high speeds. The test evaluates the shingles’ ability to resist damage from impacts of different sizes and strengths. Shingles that meet the test requirements are rated as Class 4 and are considered the most durable and impact-resistant shingles available.

Class 4 shingles undergo rigorous testing to ensure the can withstand impact from a 2-inch steel ball dropped from a height of 20 feet without cracking or showing any signs of damage. This testing is conducted by organizations such as Underwriters Laboratories and the International Code Counsel.

The Differences of Class 4 Shingles

Impact Resistance: Class 4 shingles have a higher impact resistance than Class 3 shingles. They can withstand impacts from larger hailstones and are less likely to be damaged by falling debris, such as tree branches. Class 4 shingles typically have a larger hailstone impact rating and can resist impacts from 2-in-diameter hailstones at a higher speed than Class 3 shingles.

Durability: Class 4 shingles are made of thicker and more robust materials than Class 3 shingles, which makes them more durable and able to withstand extreme weather conditions. Class 4 shingles often have a longer lifespan than Class 3 shingles and are less likely to crack, break or warp over time.
