About Sleeping Giant Roofing
Honest, climate-built roofing for Thunder Bay and Northwestern Ontario.
Roofing Built for Northwestern Ontario
Sleeping Giant Roofing is built on a simple idea: a roof in the North has to be built for the North. We focus on Thunder Bay and Northwestern Ontario, where the climate, not curb appeal, decides how long a roof lasts. From the older streets of Port Arthur and Fort William to the newer subdivisions up in County Park and the rural properties out toward Oliver Paipoonge and Neebing, we build roofs to handle what Lake Superior sends.
Up here the challenges are specific and relentless: heavy snow load that sits for months, repeated freeze-thaw that pries at flashing and feeds ice dams, and cold wind off the lake that lifts and tears roofing. We do not take a one-size-fits-all approach. We recommend the material and the installation that actually suit your roof and our winters, which is why we push metal so often as the long-term answer.
What We Stand For
Quality Workmanship
Every roof we build is meant to last through Northern winters. We use the right materials, follow manufacturer specifications, install ice-and-water membrane and proper ventilation, and never cut the corners that come back as leaks.
Honest Communication
We tell you what your roof actually needs, nothing more. If a repair will do, we say so. If the roof is at end of life, we say that too. Our quotes are detailed, transparent, and honoured.
Built for the Climate
We design every roof around snow load, ice dams, freeze-thaw, and lake wind. That focus on the real Northern conditions is what separates a roof that lasts from one that fails the first hard winter.
Safety First
Our crew follows strict safety protocols on every job, which matters even more on snowy, icy Northern roofs. We carry full liability and workers' compensation insurance, so you have complete peace of mind.
Why a Northern Roofer Matters
A roof in Thunder Bay is a different job than a roof in southern Ontario, and it should not be built like one. The materials that hold up here, the ventilation that prevents ice dams, the snow guards that control where snow slides, the shorter season we have to work in, all of it takes local knowledge. We build for the conditions that actually exist outside, not a generic spec.
We also keep it straight. No fabricated reviews, no invented history, no pressure. We would rather earn your trust with an honest assessment and good work than with a sales pitch.
