Flat Roof Stittsville
Repairs, inspections and replacement for low-slope roofs on Stittsville's homes and its newer commercial buildings.
The short answer
We serve Stittsville with flat roof repair, inspections and replacement. Stittsville has grown quickly, so many roofs here are relatively young. That changes the conversation: instead of whether an old roof is worn out, the useful questions are whether a specific detail was built well, whether drainage works, and how to keep a good roof in good condition.
Looking after a younger roof
A new or nearly new low-slope roof still benefits from attention. The first few winters reveal drainage problems and details that weren't finished well. A baseline inspection — with photographs of drains, flashings and penetrations — gives you a record to compare against and catches issues while they're small.
If you've recently bought a home or a commercial unit, a baseline inspection is also a sensible way to understand what you've inherited.
Residential low-slope sections
Flat sections over garages, porches and bays are common. They tend to fail at the same places: where the roof meets the wall, at the scupper or downspout, and around anything that penetrates the membrane, such as a vent or light fixture. Keeping the scupper clear and checking the wall junction after winter covers most of the risk.
Newer commercial plazas
Commercial strips in Stittsville often use single-ply membranes on large, simple roofs. The membrane field usually performs well; attention goes to rooftop unit curbs, drains and damage from trades walking to equipment. A walkway pad along regular service routes can be a worthwhile addition.
Questions we ask during an assessment
- Where does water appear inside, and does it follow rain, snowmelt or both?
- How old is the roof, and are there records of past repairs or re-roofing?
- Which membrane is on the roof now — TPO, EPDM, SBS modified bitumen or an older built-up gravel roof?
- Where does water drain — interior drains, scuppers or an eavestrough edge — and does it clear after a storm?
- Is there rooftop equipment, a deck, skylights or a wall the roof meets?
- How is the roof reached safely, and is the building occupied during work?
When replacement comes up
On younger roofs, replacement is uncommon unless there's a design issue — for example, a roof without enough slope to drain, or one built without adequate insulation that has developed condensation problems. In those cases a repair can't solve the underlying cause, and we'll explain why. Otherwise, targeted repairs and maintenance are usually the right answer.
Service area, not a branch office
Flat Roof Ottawa does not operate a branch office in this community. We travel to properties here from our Ottawa base, and the same assessment, written scope and quote process applies across the city.

Frequently asked questions
Is it worth inspecting a newer flat roof?
Yes. A baseline inspection records the roof's condition and catches early drainage or detailing problems before they cause damage.
What's the most common problem on garage flat roofs?
Leaks at the roof-to-wall junction and at scuppers or downspouts, often made worse by ice in winter.
Do you work on commercial roofs in Stittsville?
Yes. We inspect, maintain and repair low-slope commercial roofs, including flashings at rooftop units and drains.
