  • Can I add solar panels to an Interlock Metal Roofing System?

    All our products are solar compatible. Our solar brackets can be installed to house solar crystalline panels.

  • 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.

  • Does a Metal Roof Attract Lightning?

    No, a metal roof does not attract lightning. In fact, metal roofing is a safe option because it is non-combustible and provides excellent protection during a lightning storm. Metal roofs do not increase the likelihood of a lightning strike, and if lightning does strike, the metal can safely dissipate the electrical charge.

  • Do metal roofs get hot?

    Interlock Metal Roofing Systems are protected with the  Alunar® Coating System that is designed to be energy-efficient and cool. The Alunar® Coating System reflects solar heat, keeping your roof cooler and reducing the heat absorbed by your home. This helps maintain a comfortable indoor temperature, lowers energy costs, and contributes to a more sustainable environment.

  • Can you walk on a metal roof?

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

  • What type of metal is used for an Interlock Lifetime Roofing System?

    All Interlock® Metal Roofing Systrems are constructed from heavy gauge aluminum and coated with the Alunar® Coating System.


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

  • Can I install an Interlock Roof myself?

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