How Flat Roofs Age in Maple
Most of Maple went up in the last few decades as sloped roof subdivision housing, so the flat roofing hides in small pieces: the deck over an attached garage, the portico roof at a front entry, a rear sunroom or family room wing, and the occasional modern flat roofed custom build. Small does not mean simple. These decks are usually boxed in on two or three sides by taller walls, they catch snow shed from the main roof above, and they drain through a single scupper or a short run to the eave. Retail plaza and big box roofs along the arterials supply the commercial half of the picture.
What We Do on Maple Roofs
Around Maple we repair and replace garage, portico and sunroom decks, chase leaks that surface far from their source, rebuild wall upturns and counterflashing, correct slope and drainage on decks that hold water, reflash skylights, and re roof retail plaza fields. Emergency flat roof repair is available around the clock.

Systems That Suit Maple
Small residential decks work best on a two ply SBS modified bitumen system, or EPDM laid fully adhered, since each turns up a wall neatly. Plaza and big box fields take TPO, or PVC where restaurant exhaust is involved. Liquid applied covers tight, cut up areas. Compare every flat roofing system.
Two Ply
Modified Bitumen
Torch-applied or self-adhered SBS in two plies, with a granule-surfaced cap. The default on Toronto houses because it handles tight perimeters, curbs and wall terminations without a wide sheet.
- 15 to 20 year service life
- Redundant second ply
- Repairs patch cleanly
Torch Free
Cold-Ply
The same two-ply build assembled in cold adhesive rather than with an open flame. It is what we specify over occupied buildings, beside vinyl siding and anywhere a torch is not welcome.
- No open flame on the roof
- Low odour on occupied buildings
- Granule-surfaced cap
Single Ply
TPO and PVC
Hot-air welded thermoplastic sheet, laid in wide rolls with far fewer seams. It suits large commercial fields, and the reflective white surface keeps a warehouse roof cooler through a Toronto summer.
- Welded rather than glued seams
- Reflective white surface
- Fast over large areas
Rubber
EPDM
A synthetic rubber membrane that stays flexible through freeze thaw movement and takes ponding better than most. Common on garages, additions and small commercial decks.
- Flexible in cold weather
- Tolerates standing water
- Simple to detail and repair
Local Considerations in Maple
The conditions that decide how long a roof here lasts, and what we detail differently because of them.
- Snow slides off the main sloped roof onto the small flat deck below and freezes at the edge, and the ice dam that builds there pushes meltwater back under the membrane termination.
- A garage or portico deck in Maple often drains through one scupper or outlet, so a single blockage puts the whole surface under water rather than just a corner.
- Newer subdivision decks were frequently framed with barely any fall, and once the structure has settled the low spot ends up nowhere near the outlet.

Maple Flat Roofing Questions
Straight answers to what people ask us about a roof on this street.
Why does the ceiling in my Maple garage stain every spring?
Almost always the flat deck above it. Snow from the sloped roof collects there through winter, an ice dam forms at the low edge, and meltwater backs up over the membrane termination instead of running off. The stain appears in the thaw, not during the storm. Repair means rebuilding the edge detail and the upturn, sometimes with added slope built in.
Can a small flat deck be repaired, or does it all need replacing?
If the membrane is sound and the trouble is one flashing, a seam or a rusted scupper, a targeted repair is fine and we do plenty of them in Maple. Once the surface carries multiple patches, blisters across the field, or wet insulation underneath, replacing a deck that small usually costs less than another round of repairs.
How long does replacing a flat deck in Maple take?
A single garage or portico deck is normally a one day job: tear off, deck inspection, new insulation, a two ply membrane and fresh flashings. A sunroom or larger rear wing can run to two days. A Maple plaza roof is quoted in sections and scheduled around tenant hours. The timeline is confirmed in writing before anything starts.
Do you handle commercial plaza roofs in Maple as well as houses?
Yes, residential and commercial both. Retail and plaza roofs in Maple are wide single fields carrying rooftop units, interior drains and plenty of exhaust penetrations, and they get re roofed a section at a time so tenants stay open. Free no obligation quotes apply to a strip plaza exactly as they do to a garage deck.
