Roof Repairs & New Roof Installations

Architectural fiberglass laminated shingles are the most popular choice for roofing work nowadays, and are the preferred style for homeowners in Simcoe County, North York Region and North Durham Region. These asphalt-based shingles are coated with a fiberglass layer, making them extremely durable and, when installed correctly, eliminate common roofing issues such as lifting, curling, cracking, and blow-offs that can occur with standard 3-tab asphalt shingles. In addition to being more economical than metal, wood, tile, or slate roofing, laminated shingles are known for their ease of maintenance and impressive lifespan. Ontario Certified Roofing uses fiberglass laminated shingles for all our roof repair and roof replacement projects.

Vinyl Siding

Vinyl Siding Installation

Vinyl siding is easily the most popular choice for exterior cladding because it’s inexpensive, widely available, simple to install, and easy to maintain. New vinyl siding can instantly give your home enhanced curb appeal.

However, not all vinyl siding is the same. There are varying degrees of quality on the market today, with many of the low-cost options proving to have a shorter lifespan, susceptible to colour fading, and can often bend or crack, thereby breaking the seal against the home. At Ontario Certified Roofing, we only provide premium-quality vinyl siding products and meticulously install them with unparalleled attention to detail. The result? You receive a brand-new home exterior, without breaking the bank.

Windows & Doors

Exterior Caulking for Windows & Doors

Caulking the seams and joints around the windows and doors on your home is the only way to ensure an air and water-tight seal. It’s the easiest way to keep the warm air in and the cold air out, while ensuring that a solid moisture barrier is in place to avoid condensation build up. Caulking can also be used for following:

  • Sealing the joints and corners of your eavestroughs.
  • Sealing the joints around your vinyl siding.

Installation & Repair

Soffit, Fascia & Eavestrough

Soffits, fascia and eavestroughs are key components to ensuring proper protection for your home, while extending the life and durability of your roof. They all work together, so if you’re in need of repairs or replacements to one component it’s recommended that you have all three assessed at the same time.

Soffits are the aluminum panels seen on the underside of a roof line, and come in both solid and vented styles. Their function is not just aesthetic – the solid panels provide the seal between the roof line and the home to keep birds and rodents out, and the vented panels allow air to enter the attic space for ventilation.
The term “fascia” is commonly referred to two components – the structural wood boards that support the edge of the roof line and eavestroughs, and the aluminum cladding that covers these boards. Fascia boards are seen on the rakes of a roof line, along with what the eavestroughs are attached to. If there is any damage to the soffits or the eavestroughs, it’s very common for the fascia boards surrounding the damaged area to be affected as well, as this is one of the most vulnerable areas of a home for water penetration to occur. The aluminum cladding that covers the fascia boards can become damaged in high winds, or by animals picking away at the edges. To update the look of your home, it’s also very common to install a new colour of fascia.
Eavestroughs (or gutters) are the drainage system for your home. Their purpose is to capture the water run-off from the roof and guide it away from the home via the downspouts. Most eavestroughs are aluminum and come in 4”, 5” or 6” sizes and are installed via spikes into the facia boards or, more commonly nowadays, via a seamless bracket system.
