Class A Fire-Rated-Protection
Interlock® Metal Roofing provides Class A fire-rated protection — the highest standard in residential roofing. Our interlocking aluminum shingles are non-combustible and engineered to resist ignition from embers, sparks, or direct flame exposure. This makes them an ideal choice for homes in wildfire zones or rural areas where structural fire risk is elevated. Unlike wood or asphalt, which can accelerate fire spread, Interlock roofs help buy you time — and peace of mind. Built to withstand extreme heat and designed to protect, our fire-resistant roofing gives your home the defence it deserves.

For instance, a home with a 3/12 pitch is easier for our installers to work on therefore labour costs will be less expensive.

Does a metal roof attract lightning?
No, a metal roof will not increase the likelihood of lightning striking, but it may make a lightning strike less hazardous if it does occur. A conductive metal roof provides a low-resistance path for lightning to reach the earth.
Are metal roofs hot?
All Interlock Metal Roofs are coated with the Alunar® Coating System. The "Cool Roof" ceramic pigment technology in the coating reflects and emits more of the sun's UV rays, preventing them from entering the attic space. Interlock Metal Roofing Systems are CRRC rated (Cool Roof Rating Council).
Do metal roofs protect against hail?
All Interlock® Roofs are made from heavy-gauge aluminum, which has been tested and has surpassed the industry standard measurement for impact resistance: UL 2218 — Standard for Impact Resistance of Prepared Roof Covering Materials.
Can you walk on a metal roof?
How to Safely Walk on a Metal RoofWhile it is safe to walk on, in accordance with the manufacturer’s instructions, the low-maintenance Interlock Roof almost eliminates that need.
What metal is an Interlock® Lifetime Metal Roofing Systems made from?
All Interlock® Lifetime Metal Roofing Systems are available in heavy-gauge aluminum coated with the Alunar® Coating System.
