Roofing for Homeowners
Residential Roofing Services in Ottawa
Ottawa Roofing Pros is a residential roofing company that repairs, replaces and maintains roofs on homes across Ottawa. We work on everything from 1950s Nepean bungalows and Glebe infill flat roofs to 2000s Barrhaven two-storeys still wearing their first shingles.
Over more than 17 years and 1,500+ roofing jobs, we have learned that most Ottawa roof problems start at the edges and in the attic. That is why our crews treat shingles, flashing, ventilation and eavestroughs as one system.
Find the service you need below, or use the repair-or-replace table to see where to start.
Our Residential Roofing Services
We handle every part of a home's roof, from a single lifted shingle to a full tear-off, and we answer the phone 24/7. Each service below has its own page with process, pricing and the problems we see most on Ottawa homes.

Roof Repair
Leaks, wind-lifted or missing shingles, failed flashing and worn vent boots on roofs with life left in them. Our roof repair for leaks and shingles starts with finding the true source.
Emergency Roof Repair
Water coming through a ceiling at 2 a.m. or a tree limb through the roof. Our 24/7 emergency roof repair crews stop the water, tarp the damage and document it for insurance.
Roof Inspections
A close look at shingles, flashing, penetrations, ventilation and attic moisture, with photos. Book a roof inspection with a written report before buying, selling or budgeting.
Skylights
Leaking curb-mounted units, foggy glazing and old flashing kits are common on 1980s and 1990s homes. We handle skylight installation and repair, ideally timed with a re-roof.
Eavestroughs, Soffit and Fascia
Seamless aluminum eavestroughs, downspouts, leaf guards, soffit and fascia that move water off the roof and away from your foundation. Get details on eavestrough installation and repair.
Repair or Replace? Start Here
Repair a roof that is mid-life with an isolated problem; replace one that is near or past its rated life with damage in several places. The table matches what you are seeing to the right starting point.
| What you are seeing | What it usually means | Where to start |
|---|---|---|
| One leak on a roof under 15 years old | A local flashing, vent boot or shingle failure | Roof repair |
| Missing shingles after a windstorm | Wind damage, possibly an insurance matter | Roof repair, plus help with a roof insurance claim |
| Water coming in right now | Active leak that will spread | Emergency roof repair |
| Curling shingles, bald patches, granules in the eavestrough | Shingles at the end of their life | Roof replacement |
| Leaks in two or more areas, or a soft, sagging deck | Widespread wear or deck rot | Roof replacement |
| Buying a home or unsure of the roof's age | Unknown condition | Roof inspection |
Minor repairs in Ottawa typically cost $350 to $1,200, while most detached homes pay $10,000 to $24,000 for an architectural shingle replacement. A free assessment tells you which side of that line your roof is on.
Roofing Materials for Ottawa Homes
Architectural asphalt shingles suit most Ottawa homes on budget and appearance, steel roofing suits owners staying 20+ years, and membranes suit flat or low-slope sections. Each handles snow differently, which matters as much as price here.
| Material | Typical lifespan | Installed cost (2026) | Snow and ice performance |
|---|---|---|---|
| Asphalt shingle roofing | 20 to 30 years | $500 to $800 per square | Holds snow; relies on eave membrane and ventilation to resist ice dams |
| Metal roofing for Ottawa homes | 40 to 60 years | $900 to $1,400 per square; standing seam $1,200 to $1,800 | Sheds snow; needs snow guards over doors and walkways |
| Residential flat roofing | 20 to 30 years | $12 to $20 per sq ft | Carries the snow load; drainage is critical |
Weighing steel against shingles? Our metal roof vs shingles comparison runs the numbers over 40 years.
Built for Ottawa's Freeze-Thaw Climate
Ottawa typically gets more than 2 metres of snow a winter and close to 80 freeze-thaw cycles a year. A roof that survives that is built as a system: sealed edges, a cold roof deck and a well-insulated attic.
Skip any one of those and the other two cannot compensate. These are the three pieces we check on every home.
Eave Protection at Every Edge
Self-adhered ice-and-water membrane, such as Grace Ice & Water Shield, goes at the eaves, in valleys and around chimneys and skylights. The Ontario Building Code requires eave protection on most shingle roofs over heated space, running at least 900 mm up the slope and 300 mm past the inside of the exterior wall.
Ice Dam and Snow Removal
When ice dams form, steam removes them without gouging shingles the way chipping does. Our ice dam removal and roof snow clearing service also relieves heavy snow loads on flat roofs and garages.
Attic Ventilation and Insulation
Ice dams start with heat leaking into the attic and melting snow from below. Attic ventilation and insulation upgrades balance soffit intake with ridge exhaust and bring insulation up to current levels.
