KNOW THE SIGNS
Is It Time for a Roof Replacement in Hamilton or Just a Repair?
Most asphalt shingles in Hamilton can last 20 to 25 years. Quality architectural shingles can push 30 years or more. If your roof is approaching that age, or you find yourself calling for repairs every spring, a full roof replacement in Hamilton is almost always the smarter long-term decision.
Not sure which route makes sense? Book a free no-pressure roof inspection and we will tell you honestly whether a repair will hold or it is time to replace.

ROOFING MATERIALS
Roofing Materials for Hamilton Homes Installed Right
We install the roofing materials that hold up best through Ontario freeze-thaw cycles, the heavy Hamilton winter snow loads, and summer heat. Every product we carry is selected for lifespan, warranty coverage, and proven performance in this climate.
Architectural Asphalt Shingles
130 km/h. Most popular choice for Hamilton roof replacement projects. Available in a wide range of colours and profiles.
Best for: Standard residential homes across Hamilton
Designer Luxury Shingles
Dimensional profile that mimics cedar shake or slate. Enhanced impact and wind resistance. Ideal for premium curb appeal.
Best for: Heritage Hamilton homes or upgraded aesthetics
Standing Seam Metal Roofing
Excellent snow shedding and low maintenance. Higher upfront cost with significantly lower lifetime maintenance expense.
Best for: Long-term ownership and energy savings
Cedar Shake Shingles
Natural appearance with solid insulation value. Requires maintenance to prevent moisture retention in Hamilton’s climate.

NEW ROOF FAQ
Hamilton Homeowners' Most-Asked Questions About New Roof Installation
Most residential roof replacements in Hamilton are completed in one to two days. A standard two-storey home with a 2,000 square foot roof takes one full day for our crew. Homes with steep pitches, multiple sections, or significant decking damage may take two to three days. A confirmed timeline is included in your written quote.
We always perform a full tear-off before any new roofing services in Hamilton. Installing new shingles over an existing layer traps moisture, voids manufacturer warranties, and prevents proper decking inspection. Every Green Peaks new roof installation starts with a complete tear-off so the work underneath is done right.
Late spring through early fall is ideal for new roof installation in Hamilton. Warm temperatures allow shingles to seal properly and adhesive strips to activate. Our crews also complete winter roof replacements successfully when temperatures and materials are managed correctly throughout the process.
Yes. Green Peaks Roofing pulls the required City of Hamilton building permit for every full roof replacement. We manage the submission, scheduling, and inspection process so homeowners do not need to coordinate with the city directly.
Every new roof installation in Hamilton includes a written workmanship warranty covering labour and installation defects, plus the manufacturer product warranty on roofing materials. Warranty terms vary by material selected and are reviewed in full at your estimate appointment.
A properly installed architectural asphalt shingle roof in Hamilton typically lasts 25 to 30 years. Lifespan depends on shingle grade, attic ventilation quality, and regular maintenance. Roofs installed with correct ice and water shield and proper roof ventilation consistently reach the upper end of their rated lifespan in Ontario's climate.
A new asphalt shingle roof in Hamilton typically costs between $9,500 and $18,000 for a standard single-family home, depending on roof size, pitch, and material selected. Architectural shingles fall in the $10,000 to $16,000 range for most properties. Green Peaks provides a free detailed written estimate with a fixed all-in price before any work begins.
