GALENA, Kan. — Due to popular demand and positive feedback from contractors, TAMKO Building Products LLC is extending the purchase window for The Heritage Proline™ Challenge, a rewards program that challenges roofing contractors to try the innovative Heritage Proline Titan XT™ and StormFighter IR™ shingles and pays them cash back on their qualifying purchases of the products.

Roofing contractors can now receive cash back rewards on purchases of Titan XT and StormFighter IR shingles made through Dec. 31, 2021. Previously, the purchase deadline was Oct.15.

“Contractors rising to the challenge have been happy with their results. We’ve had tremendous feedback on both The Heritage Proline Challenge program and the Titan XT and StormFighter IR shingles,” said Alex Hines, TAMKO’s vice president of sales and marketing. “We’re thrilled to extend the program term so even more roofing contractors now have the chance to earn cash back rewards on our hottest products through the remainder of this year.”
