What a Flat Roof Faces in Burlington
Burlington's flat roofing is mostly the product of renovation. Older housing near the lake has been added to and rebuilt for decade after decade, so a single property can carry a flat rear addition, a sunroom deck, a garage roof and a modern rebuilt section, each done at a different time by different hands and each meeting the original roof at a different detail. Downtown, older commercial blocks hide their flat roofs behind parapets. Inland there are newer subdivisions and office and business parks with proper low slope fields. Behind all of it, the escarpment brings deeper snow and colder overnight lows than the shoreline sees.
What We Do on Burlington Roofs
Burlington calls usually start with a leak at a junction between old and new construction. We trace it, rebuild the flashing, repair or replace the membrane, renew drains and scuppers, reseal skylight and sunroom curbs, tear off and reroof whole sections, and cover 24/7 emergency flat roof repair. Estimates are free and nothing is owed either way.

Systems That Suit Burlington
Renovated residential decks in Burlington do well in EPDM or self adhered two ply modified bitumen, both of which handle the many wall terminations these roofs have. Office and business park roofs are best served by TPO, and small awkward areas around sunroom curbs suit a cold applied liquid system. 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 Burlington
The conditions that decide how long a roof here lasts, and what we detail differently because of them.
- Every seam between an original roof and a later addition is a potential leak path, and on heavily renovated properties there can be four or five of them on one house.
- Ground nearer the escarpment holds more snow and drops colder overnight, so decks up there carry load longer and cycle through freeze thaw more sharply than lakeside roofs.
- Sunroom and skylight curbs are frequently under flashed by whoever built them, and they let water in at the upslope corner first.

Burlington Flat Roofing Questions
Straight answers to what people ask us about a roof on this street.
My Burlington sunroom roof leaks at the wall. What is wrong?
Almost always the flashing where the flat deck meets the house wall. It needs a membrane upturn of adequate height, a counterflashing set into or over the cladding, and no reliance on sealant alone. On Burlington sunrooms added long after the original house, that detail is often just a bead of caulking. Rebuilding it correctly is a half day of work and ends the leak.
Do you replace flat roofs over occupied space in Burlington?
Yes, and most Burlington flat roofs sit directly over living or working space. We open only what can be closed in and made watertight the same day, protect the interior below the work area, and keep the insulation dry through the process. On commercial buildings the tear off is phased around business hours so tenants are not disrupted.
Does snow load matter on a Burlington flat roof?
It does, particularly on the higher ground toward the escarpment where snow sits longer and drifts against parapets and walls. A structurally sound Burlington roof handles normal accumulation, but drifting adds concentrated load, and the meltwater it produces still has to reach a drain. In most cases we see, blocked or frozen outlets are the real problem rather than the weight.
How much does flat roof repair cost in Burlington?
Repairs are priced by what is actually wrong, so a small seam or flashing repair is a modest fixed cost, while a section with wet insulation has to come off and be rebuilt. Full replacement sits in the $8 to $15 per square foot range. We look at the Burlington roof first, then set out the choices in a written quote, free and with nothing owed.
