Ottawa Roofers, Open 24/7
Ottawa Roofing Pros is a roofing contractor for homeowners, condo boards and commercial property owners across Ottawa. We install, replace and repair the roofs this city actually has: architectural shingles, steel and standing seam, and low-slope TPO, EPDM and torch-on membranes.
Roofing is the only trade we practise, and we have been at it for more than 17 years and over 1,500 jobs. Our crews are licensed, insured and WSIB-covered, and the phone is answered 24/7 when a leak can't wait.
We cover every part of the city and anywhere within roughly a 30-minute drive of it. Every assessment is free, and every price is set in a written quote before work begins.
We roof sloped and flat roofs on houses, multi-unit buildings and commercial properties, so a single contractor can look after a bungalow re-shingle, a townhouse block or a warehouse membrane. That matters in Ottawa, where many homes combine a pitched main roof with a flat porch, garage or rear addition.
Clients of our residential roofing services and our commercial work get the same safety standards, the same written quotes and the same labour warranty. Here is where most of our work falls.
A full roof replacement in Ottawa strips the old roof to the deck, replaces any soft sheathing, and rebuilds the system with new underlayment, eave protection, flashing and ventilation.
Most clients choose architectural asphalt shingles, steel and standing seam metal roofing, or a modified bitumen or EPDM flat roof system for low-slope sections.
Our roof repair service fixes blown-off shingles, lifted flashing, cracked pipe boots and leaking vents before they turn into ceiling stains. Most repairs are diagnosed and quoted on the first visit.
When water is coming in, our emergency roof repair crews can be reached 24/7. We give you a realistic arrival time on the call, then tarp or patch to stop the water until a permanent fix is booked.
Our commercial roofing team replaces and repairs low-slope roofs on offices, retail plazas, warehouses and apartment buildings. We work with TPO, EPDM and PVC single-ply membranes and SBS modified bitumen and built-up roofs.
Owners who would rather plan than react can set up commercial roof maintenance programs with scheduled spring and fall inspections.
A roof only works if water leaves it and the attic beneath it stays cold and dry. We install seamless eavestroughs, soffit and fascia, replace and reflash skylights, and correct attic ventilation and insulation problems that shorten shingle life.
Ottawa winters wear roofs down through four connected forces: freeze-thaw cycles, ice dams, heavy snow loads and spring meltwater. Ottawa typically sees more than 2 metres of snow in a season, and temperatures that swing above and below zero many times between November and April.
These problems share causes, so we treat them together. The Ontario Building Code requires an eave protection membrane along the lower edge of most shingled roofs here, and we pair it with balanced soffit and ridge ventilation and enough attic insulation to keep the roof deck cold.
When a dam has already formed, our ice dam and snow removal service uses low-pressure steam to clear it without hacking at the shingles.
Every project follows the same five stages, whether it is a single repair or a full re-roof. You know what is being done, what it costs and when it happens before anyone climbs a ladder.
Each service page covers the details for that type of work. This is the short version.
We walk the roof, check the attic where we can reach it, and photograph what we find. A standalone roof inspection report is also available if you are buying, selling or planning ahead.
You receive a written quote listing the materials by brand and product line, the scope of tear-off, flashing and ventilation work, and how any rotten decking will be priced. There are no verbal estimates.
We book a date, order materials and arrange the bin. Re-shingling a house usually does not need a City of Ottawa building permit, but structural repairs do, and we tell you up front if your job falls into that category.
Most detached homes are stripped and re-roofed in 1 to 3 days, depending on size, pitch and layers. The roof is never left open overnight, and gardens, siding and windows are protected before tear-off begins.
We sweep the yard and driveway with a magnetic nail sweep, walk the finished roof with you, and hand over your written labour warranty with the manufacturer warranty information for the products installed.
Ottawa Roofing Pros is licensed, insured and covered by the WSIB, and we have more than 17 years and 1,500 roofing jobs behind us. We would rather you check those claims than take them on trust.
Ontario does not issue a provincial licence to roofing contractors, so the word "licensed" on its own tells a homeowner very little. The proof worth asking any roofer for is more specific.
The Roofer trade (449A) also has a voluntary Red Seal certificate through Skilled Trades Ontario. Because it is voluntary, ask whether the people on your roof hold it rather than assuming they do.
Every job we complete carries a 1-year written labour warranty. If a leak or failure traces back to our workmanship, such as a flashing detail, fastening or a seam we installed, we come back and fix it at no charge.
Material warranties are separate and come from the manufacturer. Their length and what they cover depend on the specific shingle, metal panel or membrane installed and on whether the product is registered after installation, which we explain in your quote.
A short warranty stated clearly, with the manufacturer's coverage spelled out beside it, is easier to rely on than a long one buried in exclusions.
Clients can expect an answered phone, a written quote before any work, and a crew that cleans up as it goes. Our reviews from Ottawa homeowners and property managers are on our Google Business Profile, where you can read them in full.
When you read them, look for the details that matter on a roof job: whether the crew showed up when promised, whether the final price matched the quote, and how the company handled a problem after the job. Those are the standards we hold ourselves to on every roof.
We roof in every part of Ottawa, dispatching from our Centretown base to the suburbs, the rural villages and nearby towns within about 30 minutes of the city.
In Kanata, Stittsville, Barrhaven and Orléans, much of our work is on 1980s to 2000s subdivision homes whose original shingles are reaching the end of their life. In Nepean and Gloucester, we see more 1960s and 1970s bungalows and split-levels, often with an older layer or two to strip.
Closer to the core, Centretown, the Glebe, Westboro, Old Ottawa South and Alta Vista bring older brick homes, flat-roofed triplexes and tight lots that need careful staging. We also travel to Manotick, Greely, Riverside South, Carp, Richmond and Cumberland, and to nearby communities such as Russell, Rockland, Kemptville and Arnprior.
These are the questions Ottawa homeowners and property managers ask us most often, answered briefly.
Most detached Ottawa homes cost $10,000 to $24,000 to re-roof in architectural asphalt shingles, based on typical 2026 pricing of $500 to $800 per roofing square (100 sq ft) installed.
Steel roofing, steep pitches, multiple old layers, rotten decking and complex chimneys or skylights push the price higher. A free assessment and a written quote set your actual price.
Yes. Repairs, emergency leak calls, ice dam steaming and many replacements go ahead through the winter whenever the roof can be worked safely.
Cold weather changes the method rather than ruling the work out. Shingle sealant strips don't bond until the sun warms them, so in cold weather we hand-seal shingles following the manufacturer's cold-weather instructions, keep bundles warm before installation, and clear snow and ice before anyone works at height.
Yes. We are licensed, carry liability insurance and are covered by the WSIB, and we can show proof of each before you sign.
Because Ontario has no provincial roofing licence, ask any contractor for a WSIB clearance certificate, an insurance certificate and working-at-heights training cards. A roofer who can't produce them is a risk to you as the property owner.
Yes. We roof low-rise offices, retail plazas, warehouses, apartment buildings, and townhouse and condo corporations.
Boards and managers can read how we plan work on occupied buildings on our page about roofing for property managers and condo boards.
