Get Tdi Class 4 Form

UL 2218 Class 4 is the highest possible rating level for asphalt shingles. The lower ratings that can be given are known as Class 1, 2, and 3. The difference between the classes is the size of the steel ball used to test them.

A Class 3 rating is given to shingles that do not crack after being hit by a steel ball, measuring 1.75” in diameter and dropped from twenty feet. Class 4 is the highest after taking a hit from the same 20-foot height with a 2-inch steel ball.

Not only do they protect your home from major storms, which could otherwise destroy normal shingles and cost you a roof replacement, but they also weather better than regular asphalt shingles. Not having to replace your roof as frequently is both a time and money saver.

If the mat of the shingle does not crack on impact, the shingle receives Class 4 impact rating. To achieve Class 3 rating, the shingle must withstand a 1 ¾-inch steel ball dropped from 20 feet. Naturally, these tests are primarily intended to replicate hail stones.

Class 3 - Sample did not crack when hit twice in the same spot by a steel ball 1.75 inches in diameter. Class 4 - Sample did not crack when hit twice in the same spot by a steel ball 2.0 inches in diameter. against harmful weather.

To receive a Class 4 rating, a roofing shingle must withstand having a 2-inch steel ball dropped multiple times from a height of 20 feet. For more perspective, if this same test is repeated on a 4-inch concrete paver, the force of the steel ball would crack the paver in half.

There is no such thing as a hail resistant roof, but Class 4 impact resistant roof shingles are the most advanced asphalt roofing shingles available. Class 4 shingles have a 50-year life expectancy, far superior to the standard architectural shingles 30-year life expectancy.

Impact Resistance Shingles are rated Class 1 through 4, with Class 4 shingles having the highest resistance. You will not be able to determine the impact rating of shingles by looking at them, although the impact rating is usually marked on the cellophane on the underside of the shingle.

In terms of durability, class 4 shingles are the most durable and sturdy shingle in the industry. Remember that your shingles are your roof's first and most important line of defense. A class 4 roof with intact or undamaged shingles is much better protected than other shingles.

For impact resistance testing, the standards are as follows: Class 1: Can withstand the impact of a steel ball 1.25 inches in diameter. Class 2: Can withstand the impact of a steel ball 1.50 inches in diameter. Class 3: Can withstand the impact of a steel ball 1.75 inches in diameter.

Since 1996, the UL 2218 has provided a national standard for rating the impact-resistance of roofing materials. Materials achieve a rating of between Class 1 to 4, based on their resistance to the impact of steel balls of various sizes, simulating 90-mph hailstones. The toughest roofing materials rate a Class 4.

To qualify as UL 2218 Class 4 impact-resistant, shingles have to pass the standardized UL 2218 assessment—colloquially known as the "steel ball test." During this assessement a 2-inch steel ball is dropped, twice, from a 20-foot height on an installed shingle to evaluate the its ability to withstand the impact.
