Roof Replacement
We offer a 10-Year workmanship warranty on all our homes!
If your roof is over 20 years old, or if repairs are becoming frequent, a replacement may be the most cost-effective long-term solution. We offer several replacement options:
- Asphalt Shingles: Our most popular choice, available in a variety of colors and styles. We install GAF Timberline HDZ, IKO Cambridge, and CertainTeed Landmark shingles, all with enhanced durability and algae resistance.
- Metal Roofing: For maximum longevity and minimal maintenance, metal roofs can last over 50 years. They're fire-resistant, energy-efficient, and great for shedding snow in winter.
- Flat Roof Systems: We specialize in commercial flat roofing using TPO and EPDM membranes. Our fully adhered systems come with 20-30 year warranties.
- Eco-Friendly Roofing: Ask us about cool roofing systems that reflect sunlight and reduce heat absorption for lower energy bills.
Our team handles tear-off, disposal, underlayment, and full installation with minimal disruption to your home or business.

The Mississauga Climate – Built for Local Conditions
As seasoned roofing contractors in Mississauga, we understand the demands our local climate places on roofing systems.
Winter Hazards
- Freeze-Thaw Cycles: Cause ice dams that lead to leaks and structural strain.
- Heavy Snow Loads: Roofs must support 40-50 lbs/sq. ft. of snow in peak winter.
- Wind-Driven Snow: Can infiltrate roof edges and vents, leading to moisture issues.
Summer Threats
- UV Radiation: Degrades asphalt shingles and roofing membranes over time.
- Thermal Expansion: Repeated heating and cooling causes materials to crack and shift.
- Hail and Thunderstorms: Damage flashing, gutters, and shingles.
We install roofs designed to resist these forces — giving you year-round peace of mind.

We only work with roofing products that have been tested in real-world conditions and backed by strong manufacturer warranties. Our go-to materials include:
- GAF Timberline HDZ: Architectural shingles with LayerLock Technology for superior wind resistance.

- IKO Cambridge: A favorite for high-impact zones, featuring extra thickness and durability.
