Interlock® Tile Specification Manual
Lifetime Roofing Systems ®
Interlock® Tile Interlock Tile is an aluminum tile hidden fastener roofing system. It is specially designed to match the appearance of conventional tile roofing. The tile panels are coated with Alunar® for ultimate durability and protection. All trims are color matched to the specific Interlock color. Interlock Tile provides outstanding advantages when compared to other roofing materials.
Unique design provides incredible strength and protects against severe weather.
The look of tile is provided without the heavy cost of structural modifications. Interlock Tile can be adapted to almost any roof line and over most existing roofs.
Lightweight Interlock Tile is very lightweight, having a dry or wet weight of 70 lbs. per 100 sq. ft. This is about 96% lighter than concrete or clay tile. Huge savings are realized in structural costs for new homes and developments, as truss systems can be designed for less stress and weight loads.
Environmentally Friendly Sustainable, recyclable and helps stop roofing material going to the landfill.
