Single Point of Contact
One project contact handles your buildings, knows their history and answers your calls and emails. You don't re-explain a roof every time a new trades person visits.
Condos and Managed Properties
Ottawa Roofing Pros works with condominium boards, property management firms and landlords who look after townhouse complexes, low-rise and mid-rise condos and rental apartment buildings. We inspect, repair, maintain and replace their roofs, and we produce the reports and paperwork boards need to make decisions.
Our crews bring more than 17 years and over 1,500 roofing jobs to this work, on shingle, flat and metal roofs alike. We know a roof project on a residential building is as much about residents, notices and approvals as it is about membranes.
We are licensed, insured and WSIB-covered, and we answer roof emergencies 24/7.
We give property managers and boards one accountable roofing contractor for every building in their care, from routine inspections to full replacements. That means predictable reporting, clear priorities and fewer surprise invoices.
The way we work with managers rests on four commitments.
One project contact handles your buildings, knows their history and answers your calls and emails. You don't re-explain a roof every time a new trades person visits.
We inspect each roof in spring and fall, clear drains and eavestroughs, and fix small problems before they reach a unit. Our commercial roof maintenance programs cover the details and plan options.
Leaks into occupied units can't wait for business hours. Our phones are answered 24/7, and our commercial roof repair crews make the roof safe first, then send a photo report once the leak is controlled.
Every visit ends with a dated photo report: what we found, what we fixed and what is coming next. Roof plans with numbered sections let boards follow each problem over time.
We prepare roof condition reports with remaining-life estimates and replacement cost ranges that your reserve fund study provider can use. The study itself is done by the corporation's qualified reserve fund study provider; our report gives them roof-specific data from someone who works on roofs every day.
Under Ontario's Condominium Act, 1998 and its regulation O. Reg. 48/01, a condominium corporation needs a comprehensive reserve fund study with a site inspection, followed by updated studies every three years that alternate between updates with and without a site inspection. After receiving a study, the board has 120 days to propose a funding plan and must then send owners a notice summarizing the study and plan. A roof is often one of the largest single items in that plan, so good roof data matters.
Our roof reports typically cover:
These are the typical Ottawa service lives we start from, before adjusting for each roof's actual condition:
| Roof system | Typical service life in Ottawa |
|---|---|
| Architectural asphalt shingles | 22 to 30 years |
| TPO or PVC single-ply | 20 to 30 years |
| EPDM single-ply | 25 to 30+ years |
| Two-ply SBS modified bitumen | 20 to 30 years |
| Standing seam metal | 40+ years |
Ventilation, drainage and maintenance history can move a roof well above or below these ranges, which is why the report is based on what we find on the roof, not the install date alone.
When a reserve fund can't support a replacement yet, a restoration coating or targeted repairs may bridge the gap, and we price both options side by side.
We respond to tenders with complete, compliant bid packages and price exactly to the consultant's specification. Managers and engineers can compare our bid line by line, without chasing missing documents.
A typical package from us includes:
When a board has no consultant, we can write a clear scope instead: replace like-for-like, or upgrade the system, insulation or drainage. Under section 97 of the Condominium Act, repairs or replacements with materials reasonably close in quality to the original are generally not treated as alterations to the common elements. A true upgrade can trigger owner notice or, if substantial, an owners' vote, so boards should confirm the approval path with their condominium lawyer before tendering.
Residents accept roof work far more easily when they know what is happening, when and why. We give managers clear notice content for each phase and keep crews to the schedule it promises.
Our resident notices cover:
Two rules shape the schedule. Ottawa's Noise By-law (2017-255) bars construction noise before 7 a.m. and after 10 p.m. Monday to Saturday, and before 9 a.m. or after 10 p.m. on Sundays and holidays. On occupied buildings, we usually start noisy work later than the by-law allows.
When we need to enter a unit to trace a leak, the entry rules apply. Condominium corporations must give owners reasonable notice under the Condominium Act, and landlords of rental buildings must give tenants at least 24 hours' written notice under the Residential Tenancies Act, except in emergencies.
Townhouse and low-rise condo roofs are usually replaced in phases, one block or group of blocks at a time, so the cost lines up with the reserve fund's cash flow. A complex of 10 or 12 blocks might be re-roofed over two to four seasons.
Many townhouse condominiums served by our Orléans roofing crews, our Gloucester roofers and our roofing team in Nepean were built in the 1970s through the 1990s and are on their second or third roof. Phasing raises questions that a single house never does:
Sloped shingle roofs follow our asphalt shingle roofing standards, at typical Ottawa prices of $500 to $800 per roofing square (100 sq ft) installed in 2026. The number of phases, skylights, ventilation upgrades, eavestrough work and access between blocks move that price, and a written quote after a free assessment sets it.
Mid-rise condo and rental buildings with flat roofs follow our commercial flat roof replacement process, at $10 to $18 per sq ft for single-ply. All of our condo roofing sits within our wider commercial roofing services, backed by our 1-year written labour warranty plus any manufacturer warranty that applies.

Boards and managers tend to ask the same questions before a roof project reaches a meeting agenda. Here are our answers.
Start two to three years before your reserve fund study shows the roof reaching the end of its life. That leaves time for a condition report, a funding decision, tendering and board approval.
Tendering over the winter lets the work start in late spring, when shingles seal properly and membranes and adhesives work within their temperature limits.
Yes. We inspect each roof and deliver a written condition report with remaining-life estimates, replacement cost ranges and photos, ready for your reserve fund study provider.
Usually not, if the roof is replaced with materials reasonably close in quality to the original. A significant upgrade may need owner notice or a vote under section 97 of the Condominium Act, so confirm with your condominium lawyer.
Yes. Residents stay in their homes throughout, and we phase work, protect entrances and send notices so they know which days will be noisy.
Yes. We bid to consultant specifications, follow their site reviews and supply the submittals and close-out documents they ask for.
Yes. We maintain and replace roofs for rental apartment owners and their managers, including leak response and coordinating tenant notices for unit entry.
Our crews dispatch from Centretown to every Ottawa community and anywhere within about 30 minutes of the city.
