GAF Master Elite® and Certified Green Roofer™

Harmony Home Improvement is a GAF Master Elite contractor. GAF is the nation’s leading manufacturer of high-quality roofing materials like asphalt shingles. Becoming GAF Master Elite® is something only 2% of all roofing contractors in North America are ever invited to do. Becoming a Master Elite® roofing contractor requires maintaining excellence in quality of work, extensive training, warranty capabilities, and customer satisfaction, and certification is only open to contractors with over 7 years of experience (no fly-by-night roofers allowed). Also important to us is the fact that GAF promotes sustainability in all areas of their business. As Certified Green Roofers, we are experts on energy efficiency, material optimization, and the recycling of products.

TAMKO® Pro Master Roofer

TAMKO has been a leading manufacturer of residential roofing shingles in the USA for over 75 years. Our status as TAMKO® Mastercraft Certified Contractors means we’re able to offer our customers access to three enhanced shingle warranties, as well as an optional roof system warranty. It’s part of our commitment to making sure your roof is covered — so it keeps covering you.
