What Is a Class 4 Roof? Metal Roofing Explained

A great number of materials is available for installing a roof on a new home or completely refurbishing an existing roof. Regardless of the current roof style on your home, metal roofing can be an appealing alternative due to its longevity, low maintenance, and energy efficiency. The best classification of roofing you can get is Class 4, but not everyone knows exactly what that means. If you need metal roofing explained, keep reading to find out exactly what a Class 4 roof is.

What Does Class 4 Mean?

A number of independent testing organizations, such as UL (Underwriters’ Laboratories), provide verifiable information to consumers to assist them in making informed decisions about items such as impact-resistant roofing materials. The impact rating test, which determines if a roofing material is Class 1, 2, 3, or 4, was created to rate the strength of roofing materials. In order to achieve a Class 4 impact resistance certification, materials must sustain two strikes by a 2″ diameter steel ball without breaking or demonstrating any other sort of damage to their structural integrity. The outside surface, backing, and interior layers must not exhibit any signs of cracking, tearing, fractures, or splitting or other evidence of impaired integrity.

Why Is the Class Important?

Resistance to impact is crucial, since it’s a measure of hail and debris resistance. In general, manufacturers cannot describe their products as “hail proof,” but products rated as Class 4 have met the highest level of resistance that UL has found appropriate. Purchasing Class 4–rated materials means your roof will have a lower risk of damage during a hailstorm or severe windstorm, where debris might collide with the roof. Furthermore, when a roof fails, the cost of rebuilding it isn’t the only cost you’ll face—if the hail or debris causes a leak, extra damage is likely to happen inside the building. Your roof is considerably more likely to stay watertight even after weather damage with Class 4–rated metal systems.
