What is a Class 3 and 4 Impact Rated Roof

Colorado Springs roofing company repairs hail damage

Roofing shingles are versatile materials that come not only in a wide array of styles and colors, but also in many different quality categories. The two highest quality classes are Class 3 and Class 4, both categories including products that provide a certain level of resistance to impact. Here are some things that you should know about the two classes:

  • The testing process – Class 3 and Class 4 shingles are tested in labs. The tests include dropping steel balls of various sizes and weights, from various heights onto the shingles, then the shingles are inspected to check how they resisted the stress they were exposed to;
  • The performance of Class 3 shingles – the shingles that are awarded this category do not crack when hit twice in the same spot by a steel ball with a diameter of 1.75 inch;
  • The performance of Class 4 shingles – these samples can withstand impact when hit by a ball with a diameter of 2 inches twice in the same spot;
  • The importance of using these products – the roofs that use Class 3 or Class 4 shingles are much more durable and much safer than the roofs with lower ratings. An innovative Colorado Springs roofing company confirms that these top-rated roofs are also eligible for insurance premium discounts.
