NASHVILLE — TAMKO Building Products Inc. is expanding its popular Heritage line of laminated asphalt shingles to include a new Heritage IR shingle.

The innovative new 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 homeowner insurance premium discounts. Requirements and discounts vary based on insurance provider and state. Homeowners should check with their insurance agent about potential savings on their home insurance premiums.

“Homeowners in our area specifically ask for IR shingles – that’s why this is important to us,” said Curt Boyd, owner of Academy Roofing Inc. in Denver. “And TAMKO is our primary shingle manufacturer of choice, so this new product allows us to offer a full line of shingle choices that includes all the options our customers request.”

Heritage IR shingles feature the same natural beauty that has made the Heritage® line such a popular choice among homeowners for more than 40 years. Naturally deep shadow lines portray the look of wood shakes, and four attractive color choices – Rustic Black, Rustic Slate, Thunderstorm Grey and Weathered Wood – will enable homeowners to find the Heritage® IR shingle that best complements their home.

And the new Heritage IR shingles will come with TAMKO’s new limited lifetime warranty that includes a 10-year full start period. Learn more at TAMKO.com.
