About Us
“The best part is knowing that our roof will continue to look great for many, many years – long after conventional asphalt shingles would be cracking, curling, fading, streaking and collecting mold and mildew.”
Interlock metal roofs are so durable, that when you use our product, the first time you replace your roof will also be your last. Interlock Lifetime Roofing Systems are a great choice for your home and our environment.

The "Interlock" refers to the manner in which the aluminum slate and shingle roofing tiles are installed.
All four sides are interlocked to form an extremely strong roofing system that resists all kinds of extreme weather conditions, including high winds, sun belt exposure, driving snow, and heavy rains.
