Having a good, strong roof on your home is a lot like having reliable brakes on your car. You never really think about either until disaster is on the horizon. When your local weather report says harsh conditions are coming your way, it’s too late to wonder whether your roof is up to the challenge.

On the other hand, knowing that durable, impact-resistant asphalt shingles – also known as Class 4 shingles – are protecting your home can help relieve the stress associated with incoming storms or winter freezes.

Inclement weather is unavoidable, but the right asphalt roofing shingles can help your home stand up to Mother Nature.

What Does Class 4 Rating Mean?

Underwriters Laboratories (UL), an independent safety company recognized worldwide, regularly conducts impact-resistance tests on asphalt shingles. Lab technicians drop a variety of steel balls of different weights and dimensions onto an asphalt shingle from predetermined heights to determine how the shingle would hold up against impacts.

UL’s Class 4 rating means that a shingle has passed and demonstrated the highest possible class of elasticity and strength available in a roofing shingle.

Atlas Class 4 Shingles = Strength Plus Style

Atlas Roofing, which prides itself on being an industry leader in innovative roofing products, offers two StormMaster® impact-resistant shingles with a Class 4 rating:

  • StormMaster® Slate featuring Scotchgard™ Protector – Durable asphalt shingles with the traditional look of designer slate shingles.
  • StormMaster® Shake featuring Scotchgard™ Protector – Resilient architectural shingles that deliver an architectural designer charm to your home.

Inside Class 4 Shingles

Atlas uses a proprietary modified asphalt blend in the manufacturing process for its StormMaster® line of shingles, resulting in a product of superior strength that will protect your home and look good doing it.

A rubberized polymer called styrene-butadiene-styrene (SBS) is blended into the asphalt during the manufacturing process. The resulting SBS-modified asphalt shingles become stronger and more durable than traditional asphalt shingles, able to better withstand harsh weather conditions, shingle impacts such as hail and wind-driven rain.

Finally, 3M’s Scotchgard™ Protector adds an additional level of protection by creating algae-resistant shingles that maintain a clean, crisp color and appearance year after year.

Choose Style. Choose Protection. Choose Atlas.

The purchase of a new roof is something that should not be taken lightly. The right roof will last through years of storms, freeze/thaw cycles, hail and exposure to the elements. The wrong roof may fail to protect your home when you need it most, and may have to be replaced before you know it.

Choose the right shingle the first time and then rest assured that your home will be protected while adding the curb appeal of a high quality roof to your property.
