  • How much does an Interlock Roof 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 Marcella for pricing info.
