Commercial Roofing
Island Roofers delivers low-slope and flat commercial roofing for strata corporations, property managers, retail, light industrial and institutional clients across Vancouver Island. We install TPO, PVC, EPDM and 2-ply SBS modified bitumen systems, and we coordinate cleanly with tenants, consultants and building envelope engineers.

Specified to last
We work from your consultant's specifications or design a system around your building's slope, deck type, insulation R-value and parapet detailing. Every roof is documented with photos and a warranty package.

All workers carry current Fall Protection, WHMIS and Working at Heights tickets, and every site receives a project-specific safety plan before mobilization.

Commercial Roofing questions, answered.
What commercial roof systems do you install?+
TPO, PVC, EPDM single-ply membranes (fully adhered or mechanically attached) and 2-ply SBS modified bitumen (torch-on) systems. We will recommend the system that best matches your building's slope, deck type, insulation strategy and budget.
Do you work with strata corporations and property managers?+
Yes — strata and property-managed buildings are a large part of our commercial work. We provide AGM-ready quotes, coordinate tenant notices, and bill in stages to match strata cash flow.
How long do commercial flat roofs last on Vancouver Island?+
A properly installed TPO or PVC roof typically lasts 25 – 30 years on the Island; 2-ply SBS torch-on systems typically last 25 – 35 years. Lifespan depends heavily on drainage design and ongoing maintenance.
Can you handle emergency commercial leaks?+
Yes. We provide 24/7 emergency response for commercial clients with active leaks, including temporary patching and full insurance documentation.
Do you offer maintenance contracts?+
Yes — annual or semi-annual maintenance programs include inspection, drain clearing, sealant refresh and a written condition report. Maintenance is also required to keep most manufacturer warranties valid.
