Three focused services. One uncompromising standard. From new installations and emergency repairs to industry-leading ventilation — backed by 13+ years of Ottawa craftsmanship.
New Roof Systems & Replacements
Whether you're building new or replacing an aging system, we engineer roofs that last. Using Owens Corning materials — the gold standard in residential and commercial roofing — every installation is built for Ottawa's extreme climate: heavy snow loads, freeze-thaw cycles, and hot summers.
From classic asphalt shingles to flat and low-slope membrane systems, we bring the same precision to a single-family home as we do to landmark institutional buildings.
We assess your existing roof, take precise measurements, and deliver a detailed written quote — no surprises.
Choose from Owens Corning's full catalogue. We guide you to the right product for your budget and Ottawa's climate.
Crew arrives on time. Old materials removed responsibly. New roof installed and inspected before we leave the site.
Full manufacturer warranty plus our workmanship guarantee. We follow up at 30 days to confirm everything is perfect.
Leak Detection & Emergency Work
A roof leak doesn't wait for a convenient time. Neither do we. Fast response, lasting repairs — we diagnose the root cause, fix it properly, and reinforce the surrounding area so the problem doesn't come back in six months.
From minor shingle replacement and flashing repairs to full storm-damage remediation, every repair is backed by our workmanship guarantee. We stop leaks before they become catastrophic interior damage.
We locate the source — not just the symptom. Thermal and visual inspection to find exactly where water is entering.
Clear explanation of what failed and why. Written quote before any work begins. No hidden charges.
Surgical fix at the source, reinforced perimeter. We don't just patch — we prevent the next failure.
If the repaired area leaks again within our guarantee period, we return at no charge. Full stop.
Ventilation & Ice Dam Prevention
Most roofers install shingles. Few understand the science beneath them. Proper ventilation is the difference between a roof that lasts 30 years and one that fails in 10 — and Ottawa's winters make ice dam prevention critical to every structure.
As Ventilation Maximum certified specialists, we assess, design, and install complete ventilation systems that regulate attic temperature, control moisture, and eliminate the conditions that create ice dams, mold, and premature shingle failure.
We inspect airflow, insulation, and moisture levels to identify exactly what your roof system is missing.
A custom plan balancing intake and exhaust — calculated to your roof geometry and Ottawa's climate demands.
Ridge vents, soffit vents, and baffles installed cleanly and sealed properly. No shortcuts.
We identify heat-loss hotspots that cause ice dams and address them at the source — not just the symptoms.
