Line of Laminated Asphalt Shingles are Impact Resistant

TAMKO Building Products Inc. has expanded its Heritage line of laminated asphalt shingles to include a Heritage IR shingle. The reinforced shingle is classified by the Underwriters Laboratories for compliance with UL 2218 Class 4 Impact Resistance.

The UL 2218 Class 4 Impact Resistance testing by UL involves a test where a 2-inch diameter steel ball is dropped onto the shingle from a height of 20 feet, impacting the same location twice and imparting 32 joules of impact energy per drop. Afterwards, the backside of the shingle is bent over a 4-inch rod and examined for visible cracks through the thickness of the shingle. The UL 2218 Class 4 rating is the highest impact resistance rating UL awards, and to receive this rating, the shingle must withstand the impact of the test without any visible cracks through the thickness of the shingle at each of six locations selected to represent the most vulnerable areas of the installed shingle. 

The UL 2218 Class 4 classification may qualify for insurance premium discounts. Requirements and discounts vary based on insurance provider and state. Owners should check with their insurance agent about potential savings on their insurance premiums.

Heritage IR laminated asphalt shingles feature the same look that has made the Heritage line an ideal choice among owners for more than 40 years. Deep shadow lines portray the look of wood shakes, and four color choices, Rustic Black, Rustic Slate, Thunderstorm Grey and Weathered Wood, will enable owners to find the Heritage IR shingle that best complements their building.

And the Heritage IR shingles come with TAMKO’s Limited Lifetime Warranty, that includes a 10-year Full Start period. Visit online for more details about the Limited Lifetime Warranty.
