Flat Roofs in Pickering, Up Close
Roofs in Pickering are mostly pitched, which is exactly why the flat parts get ignored. The typical house has a low slope deck over the attached garage, above the front portico, or tucked onto a sunroom or back addition, and none of them are visible from the ground. They quietly collect leaves, hold snow that slid off the main roof and lose their sealant at the wall junction. On the commercial side the business parks, retail centres and institutional buildings carry proper low slope fields with rooftop mechanical, and the ones near the shoreline take open wind off Lake Ontario across an unbroken perimeter.
What We Do on Pickering Roofs
Our Pickering work covers leak investigation on hidden garage and portico decks, wall and transition flashing rebuilds, membrane repair and full replacement, drain, sump and scupper renewal across commercial fields, skylight and curb reflashing, and 24/7 emergency flat roof repair.

Systems That Suit Pickering
Small hidden decks in Pickering are best rebuilt in self adhered modified bitumen or EPDM, which terminate neatly against brick and shingle. Commercial fields go to TPO or PVC, with PVC where exhaust grease is present, and extra perimeter fastening on exposed shoreline sites. 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 Pickering
The conditions that decide how long a roof here lasts, and what we detail differently because of them.
- Flat sections tucked behind a pitched roof are out of sight, so damage accumulates for seasons before a ceiling stain forces the issue, and an annual look from a ladder catches it early.
- Mature trees drop leaves and seed into small drains and scuppers, and one blocked outlet is enough to leave water standing on a shallow deck after a single storm.
- Wind off the lake works at membrane terminations and edge metal on exposed commercial perimeters, loosening fasteners over repeated seasons.

Pickering Flat Roofing Questions
Straight answers to what people ask us about a roof on this street.
How do I know if my Pickering garage roof needs replacing?
Look for a membrane that has gone hard and cracked, laps that have opened, ponding that stays put for more than two days, blistering across the field, or soft spots underfoot that mean wet insulation or a rotted deck. On a Pickering house, if two or more of those are present across a small deck, replacement costs less over time than another round of patching.
Do you install flat roofs on new additions in Pickering?
Yes. New construction and addition work in Pickering is a regular part of what we do. We go over the deck and slope with the builder, make sure there is fall toward the outlet at roughly a quarter inch per foot, install insulation and membrane, and detail the tie in to the existing wall and the pitched roof above. Manufacturer and workmanship warranties apply.
How do you find a leak on a Pickering flat roof when the stain is nowhere near it?
Water travels along the deck, on top of the insulation or inside the wall before it drops, so the stain rarely marks the entry. On a Pickering roof we start at penetrations, drains, flashings and the transition to the sloped roof, check laps and terminations, take moisture readings where the field is suspect, and cut a small test opening if the assembly needs to be seen.
Will you work on a Pickering commercial roof after hours?
Yes. Retail and business park roofs in Pickering are often reroofed in phases outside operating hours so the tenants below carry on normally. We stage material where it does not block parking or loading, protect the interior beneath the section being opened, and close in and make watertight each area before the crew leaves the site.
