Customer Testimonial

Dec 28, 2015 / 34 Sq. Aged Copper Interlock® Shake Roof

Retired engineer Lloyd W. was happy to share his experience of replacing his hand-split cedar shake roof, with one of our aluminum profiles, Interlock® Shake in Aged Copper. He built his own house to very high standards and was very pleased with the quality of the materials used including the fasteners and snow guards since they are made of the same high-quality metal that our Lifetime Roofing Systems are. Thank you for sharing Lloyd!
