Class A Fire-Rated-Protection

Class A Fire-Rated-Protection Available

Interlock® Metal Roofing Systems are engineered with fire safety in mind — delivering high-performance protection for homes in wildfire-prone and rural areas. Our non-combustible aluminum shingles are designed to resist ignition from embers, sparks, and direct flame exposure, offering critical defense where structural fire risk is elevated.


When installed with two layers of GAF VersaShield® underlayment over a 15/32” plywood deck, Interlock Metal Roofing Systems can achieve a Class A fire rating — the highest standard for residential roofing in North America.


Unlike combustible materials such as wood or asphalt, which can accelerate fire spread, an Interlock roof helps slow ignition and buy you precious time — and peace of mind. Built to withstand extreme heat and designed to protect, our roofing system gives your home the fire resistance it deserves.


Ask your Interlock representative about our Class A fire-rated system configuration.

  • How much does an Interlock Metal Roofing System cost?

    Our product is not an off-the-shelf roofing material. Plus the installation procedures vary from structure to structure. For instance, a home with a 3/12 pitch is easier for our installers to work on; therefore, labour costs will be less expensive. A home with no valleys, chimneys, skylights, or dormers will also be less expensive. Please contact Rachelle for pricing info.

  • Are metal roofs loud?

    Our customers keep telling us that their new Interlock Roof is no noisier than their previous asphalt shingle roof.

  • Does a metal roof attract lightning?

    No, a metal roof will not make lightning more likely to strike, but it may make a lightning strike less dangerous if it occurs. A conductive metal roof gives lightning a low-resistance path to the earth.

  • Do metal roofs get hot in the summer?

    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 from entering the attic space. Interlock Metal Roofing Systems are CRRC-rated (Cool Roof Rating Council).

  • Do metal roofs protect against hail?
