What Nanaimo homeowners say
“Price and install schedule availability would limit my recommendation for some situations. Great experience overall. No complaints, just suggestions for improvement.”
“When I decided I was gonna get a new roof, I knew it was going to be a metal roof. Meeting Randal at an outdoor show made it easier to start the process. He is both friendly and professional. The quote was straightforward. I got to see pictures of other houses and colors, and samples were brought.”
“Replaced my roof on a few days, looks awesome. Great crew from vlad and his team.”
“The install team were great and were able to work around my schedule so that I didn't have to take any extra time off work.”
“We are very pleased with the material; it is the best-looking metal roof around. While they were able to work with our solar company by providing the fastening points, they had difficulty coordinating with the electricians installing a new electrical mast. This is a rare challenge for any roofing company; I expect Interlock rarely has any issues. Also, they quickly solved a leak at our chimney when it was reported. Interlock has a very fine product and a competent crew. We love the finished product. Better coordination with the solar electricians that would have avoided issues.”
“They were professionals. I am getting a lot of comments of people liking the roof.”
Roofing in Nanaimo: what to plan for
Rain from the west coast to the east
The Island ranges from very wet on the west side, around Port Alberni and Sproat Lake, to drier around Victoria, but most roofs here spend the winter damp under firs and cedars. Aluminum absorbs nothing and cannot rot. Needles still collect in valleys and gutters, and we'll tell you what to clear and how often.
Oceanfront without the rust
From Oak Bay and Sooke to Nanoose Bay and Comox, a lot of Island homes sit close to the water. Aluminum does not rust, so salt air doesn't do to it what it does to steel.
Comox Valley and upland snow
Some winters bring heavy, wet snow to the Comox Valley and the higher ground. A metal roof sheds it, so snow guards over entries, decks and driveways go in at the estimate, and the light panels leave the framing's capacity for the snow itself.
Homes in the trees
Plenty of Island homes back onto forest. Class A is available on our roofs as a complete assembly (two layers of GAF VersaShield® over 12 mm (15/32-inch) plywood, per ASTM E108), and aluminum does not ignite.
