★★★★★
“Until corrective action was taken by management, some employees did construction work they were not qualified to do.”
Wayne and Hazel G. · Duncan, BC · 2020
★★★★★
“We would have appreciated it if Interlock Roofing could have gotten to our roof faster. When they did make it out, it ended up there was only one installer that did 99% of the work, and it could have been done much quicker had they had a full installation crew. The installer was excellent.”
Alan and Janice L. · Duncan, BC · 2020
★★★★★
“Final cleanup needs to be double checked, Before the customer finds gutters full of old roofing and metal! Also communication should be made by head office to ensure a project starts on time and Always if there is any change in scheduling..”
Paul and Ulla C. · Duncan, BC · 2018
★★★★★

Philip and Holly J. · Duncan, BC · 2017

Roofing in Duncan: 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.
