What We Do
Roofing Services Built to Last
From flat membrane systems to architectural shingles — we handle every roof in the GTA with 25+ years of proven craftsmanship.
Commercial & Residential Flat Roof Specialists
Flat Roofing
Flat roofs demand precision. We install and maintain TPO, EPDM, and modified bitumen membrane systems that stand up to Toronto's freeze-thaw cycles, heavy snow loads, and summer heat. Every installation includes proper drainage planning, insulation, and a watertight seal that protects your property for decades.
- TPO & EPDM membrane systems
- Modified bitumen (torch-on) roofing
- Proper slope and drainage design
- Insulation upgrades available
- Leak detection and waterproofing
- Commercial and multi-unit residential
Architectural & 3-Tab Asphalt Shingles
Shingle Roofing
A quality shingle roof adds curb appeal and lasting protection. We install architectural and 3-tab asphalt shingles from leading manufacturers, with proper underlayment, ventilation, and flashing to prevent ice dams and moisture intrusion. We'll help you choose the right product for your home's style and budget.
