It's one thing to have a good product and another to know how to install it.

★★★★★

I would like to thank the crew of 3 that installed my new Interlock Roof from Maritime Permanent Roofing Ltd. It's one thing to have a good product and another to know how to install it. The crew worked through cold fall weather to make sure that my roof would be completed as quickly and as professionally as possible. They worked from daylight through to dusk with taking little time for breaks. They kept me informed throughout the installment and made sure material was cleaned up before they left every day. 

 

As far as the Interlocking Aluminum Roof System itself. My home now looks like it should be featured in Country Homes magazine. I have many people stop and tell me how beautiful it looks and are very interested in the product. It will take a year of going through all seasons, to see how this product holds up with our change in climate but if the warranty is as good as the crew of 3 that installed my roof, I have no worries about my roof, for the rest of my life in this house with the beautiful roof.

  • 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. Please contact Laurie for pricing info. 


    Please visit our knowledgebase for more information:

  • Are metal roofs loud?

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

  • Do you offer financing?

    Yes! We’ve partnered with Financeit and Simply Financing Group to offer you affordable monthly, bi-weekly and weekly payment options for your purchase. Visit our Financing page for more info.

  • 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.

  • 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 from entering the attic space. Interlock Metal Roofing Systems are energy-efficient 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?

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

  • What metal is an Interlock Roof made from?

    All Interlock® Roofs are available in heavy gauge aluminum coated with the Alunar Coating System.


    In addition, solid copper 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.

  • Is Interlock Roofing available in my area?

    Interlock Lifetime Metal Roofing Systems are available all across Nova Scotia, PEI, and Southern New Brunswick.
