Services · Re-Roofing & Replacement
Commercial re-roofing & flat roof replacement
When a roof is past restoration, we replace it right, tearing off to a sound deck, installing to manufacturer spec, and phasing the work so your building keeps running. TPO, EPDM, modified bitumen and BUR, backed by full system warranties.
- Tear-off vs. re-cover decision
We check the building code, which typically bans a third layer, and the structure. If a core sample shows the insulation or deck is water-saturated, a full tear-off is mandatory. We only re-cover when the existing system is dry, single-layered and structurally sound.
- Deck inspection
Once stripped to the bare deck (steel, wood or concrete), we inspect every square foot for structural deflection, rusted steel ribbing or rotting wood before anything new goes down.
- Disposal & recycling
Old materials are loaded directly into dedicated on-site bins and hauled to licensed Ontario waste-transfer facilities, prioritizing recycling centres for materials like old EPDM and metal.
- Installation to spec
We install the new system precisely to manufacturer specifications (properly staggered insulation joints and correct membrane welding or torching temperatures) so the warranty holds.
- Final magnetic nail sweep
To protect your fleet, employees and visitors, we run heavy-duty magnetic sweeps across all driving, walking and parking areas to capture stray fasteners.
- Warranty walkthrough
A project manager walks the completed roof with you, flashing execution, drain assemblies, and exactly how to maintain compliance for your long-term protection.
A full tear-off & replacement, on schedule

BeforeAfterKeeping your building running during the work
Operating a business during a major construction project takes strict orchestration. We plan around your operations, not the other way around.
Sealed by end of shift
We divide the roof into logical, self-contained sections and tear off only what can be made completely watertight by the end of that same shift.
Safe, accessible ground
Clear safety perimeters below. High-noise activities and crane operations are scheduled for off-peak hours or weekends to keep retail traffic and offices moving.
HVAC & landscaping shielded
Sensitive HVAC units are protected from debris and odours with intake coordination or charcoal filters; plywood hoarding and heavy tarping shield the landscaping below.
What happens if the deck fails mid-job
When a deck fails inspection due to hidden rot or trapped moisture, we don't halt the job indefinitely or bury the issue. We document the failure immediately with clear photography and infrared validation, then issue a transparent, itemized change order based on pre-agreed per-square-foot material and labour rates. The rest of the roof stays watertight while a dedicated crew replaces the damaged decking, so the timeline stays on track.
Exactly what your warranty covers
20–30 year NDL system warranty
No Dollar Limit coverage on both materials and manufacturer-approved leak repairs, depending on the chosen system specification.
10 year workmanship warranty
We cover the labour and installation execution with a comprehensive 10-year workmanship warranty. Your investment is fully insulated from application errors.
