Complete new roof installations and full roof replacements for residential properties across Oshawa and Durham Region. Quality materials, experienced crews, and dependable results.
When you choose Oshawa Roofers for your new roof installation, you get a complete roofing system designed and built for the demands of Ontario's climate. We do not cut corners, and every project is managed from initial consultation through final cleanup by our experienced local team.
Our residential roof installation service in Oshawa covers every component needed for a long-lasting, weather-tight roof. We go beyond simply laying shingles or panels. We build a fully integrated roofing system that protects your home, improves energy efficiency, and adds lasting curb appeal to your property.
Every layer of your roof works together to keep your Oshawa home dry and protected. The decking provides structural support, the underlayment and ice shield act as backup barriers against moisture, and the roofing material serves as the first line of defense against rain, snow, ice, and wind. Proper flashing seals every joint and transition point. When all these elements are installed correctly together, your roof performs reliably for decades, even through Durham Region's harshest winters and summer storms.
A clear, organized approach to every new roof we install in Oshawa and Durham Region. Here is exactly what to expect when you work with us.
We visit your Oshawa property, inspect your existing roof, take measurements, and discuss your needs. You receive a detailed, transparent written estimate with material and labour costs clearly outlined. No surprises, no hidden fees.
Choose from a range of asphalt shingles and metal roofing options. We help you pick the right material for your home's architecture, your budget, and Durham Region's weather conditions. We then schedule the installation at a time that works for you.
Our crew removes the old roof down to the decking, inspects every board for damage, and replaces any deteriorated sheathing. We install ice and water shield in vulnerable areas and lay synthetic underlayment across the entire deck for complete moisture protection.
We install your new roofing material according to manufacturer specifications, finish with ridge caps and flashing, and perform a thorough quality inspection. The job site is cleaned completely, debris is hauled away, and you receive your warranty documentation.
We install two primary roofing material categories for residential properties in Oshawa and across Durham Region. Both are selected for their proven performance in Ontario's demanding climate, which includes heavy snow loads, freeze-thaw cycling, summer heat, and severe storms.
Asphalt shingles remain the most popular roofing choice for Oshawa homeowners, and for good reason. Modern architectural shingles offer excellent wind resistance, strong protection against impact damage, and a wide range of colours and profiles to complement any home style. They deliver reliable performance for 25 to 30 years or more when properly installed. We work with leading manufacturers to source shingles that carry strong warranties and are rated for our regional weather conditions.
For homeowners looking for maximum longevity and durability, metal roofing is an outstanding option. Standing seam and metal panel systems can last 40 to 60 years, shed snow efficiently, resist wind uplift, and provide excellent energy performance by reflecting solar heat in summer. Metal roofing also resists moss and algae growth, a real advantage for properties in the more humid areas near Lake Ontario. While the initial investment is higher, the extended lifespan and minimal maintenance often make it the more cost-effective choice over the full life of the roof.
Affordable upfront cost, wide colour selection, proven 25-30 year performance, excellent availability, and fast installation. Ideal for most Oshawa residential properties with standard roof slopes.
40-60 year lifespan, superior snow shedding, high wind resistance, energy-efficient reflective surface, minimal maintenance, and excellent resistance to moss and moisture. A smart long-term investment for Durham Region homes.
Oshawa homeowners trust our team for quality workmanship, honest communication, and roofing that is built to last through decades of Ontario weather.

Knowing when your roof is past the point of repair saves you money and prevents interior damage. Watch for these common indicators.
Most asphalt shingle roofs in the Oshawa area have a functional lifespan of 20 to 25 years. If your roof is approaching or has passed that age, it is likely nearing the end of its effective life, even if it still looks reasonable from the ground. An aging roof becomes increasingly vulnerable to leaks, wind damage, and moisture intrusion.
Shingles that are curling at the edges, buckling upward, or missing entirely are clear signs of roof deterioration. These conditions expose the underlayment and decking to moisture and UV damage, accelerating the overall decline of your roofing system.
Finding excessive dark granules in your gutters or at the base of your downspouts indicates that your shingles are losing their protective surface layer. This granule loss leaves the asphalt exposed to UV radiation and moisture, drastically shortening the remaining life of your roof.
Dark spots, water stains, or active dripping in your attic are urgent signs that moisture is getting past your roofing system. In Oshawa's climate, where freeze-thaw cycles are common, even a small leak can cause significant damage to insulation, framing, and interior ceilings if not addressed.
A roof line that dips or sags instead of remaining straight and level indicates structural problems with the decking or framing beneath the roofing material. This is a serious issue that typically requires a complete roof replacement rather than a repair, as the underlying structure must be restored.
A sudden or gradual increase in your energy bills can indicate that your roof is no longer providing adequate insulation and ventilation. Damaged or deteriorated roofing allows conditioned air to escape and outside air to infiltrate, forcing your HVAC system to work harder throughout Oshawa's cold winters and warm summers.
