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 Marcella for pricing info. 

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

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.

All Interlock Metal Roofs are coated with the Alunar® Coating System embedded with Teflon™ Surface Protector. 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) and Energy Star® rated (Available is USA Only)

All Interlock® Roofs are made from heavy gauge aluminum which have been tested and have surpassed the industry standard measurement for impact resistance:. UL 2218 — Standard for Impact Resistance of Prepared Roof Covering Materials.

While it is safe to walk on, in accordance to manufacturers’ instructions, the low-maintenance Interlock® Roof almost eliminates that need. 

All Interlock® Roofs are available in heavy gauge aluminum coated with the Alunar Coating System embedded with Teflon™ Surface Protector.

In addition, solid copper is also available in all profiles.

While some of us enjoy a good DIY project, to kept the integrity of our Lifetime Limited Warranty we only use certified Interlock crews for installation.
