Ontario roofs need to withstand snow, wind, rain, ice, and freeze-thaw cycles. Proper installation matters. At 705 Roofing, we focus on complete roofing systems – not shortcuts to help protect your investment long- term.
On a new home, the roof is one of the first trades after framing, because the house cannot be closed in until it is. A typical order is:
Telling the roofer early where the vent stacks and exhaust fans will come through saves holes cut into a new roof later.
Ontario’s building code calls for eave protection on most shingle roofs on houses: a layer under the shingles from the edge of the roof up the slope to at least 900 mm, and at least 300 mm past the inside face of the outside wall. The code allows a few materials for this layer; on new roofs it is usually a self-sealing membrane such as ice and water shield. The code exempts some roofs, such as very steep roofs, roofs over unheated garages and porches, and some low-slope installations. The eaves are the area where ice dams push water back under the shingles. The code also sets the minimum attic vent area, the deck thickness for the spacing of the framing, and the lowest slope each roofing material can be used on.
The code is the minimum. The shingle maker’s instructions add their own rules, such as the nailing pattern and where starter strips and hip and ridge caps go, and the maker’s warranty depends on following them.
Ventilation is easiest to get right on a new home, before the roof is finished. Intake vents in the soffits and exhaust at or near the ridge work as a pair, and baffles keep the insulation from blocking the intake. Bathroom and kitchen fans must be ducted outside, not into the attic, or their moisture turns to frost on the underside of the deck. Our page on attic insulation and ventilation explains how intake and exhaust work together and how they help prevent ice dams.
Both are good choices for a new home in Simcoe County:
Whatever the choice, the decision is easier before the trusses are ordered: each material has a lowest slope it can be installed on, and a snow-shedding metal roof needs thought about where the snow lands, such as over doors, decks and walkways.
Every new shingle or metal roof 705 Roofing installs comes with a 10-year workmanship warranty. As an Owens Corning Preferred Contractor since 2019, 705 Roofing can also register Owens Corning’s extended system warranties on a new shingle roof. The levels are set out on the roofing warranty page.
If you buy a new home from a builder, Ontario’s new home warranty, administered by Tarion, also covers water getting in through the building envelope, which includes the roof, for the first two years. The homeowner makes the claim to Tarion and the builder, through Tarion’s MyHome portal, and the builder is responsible for the repair.
As soon as the framing and roof sheathing are complete. The roof is dried in first with drip edge, ice and water shield and underlayment, so the framing stays dry, and the finished roofing follows.
Usually, yes. Ontario’s building code calls for eave protection on most shingle roofs on houses, from the edge up the slope to at least 900 mm and at least 300 mm past the inside face of the outside wall, and ice and water shield is the usual material for it. Some roofs are exempt, such as very steep roofs and roofs over unheated garages. Valleys also get ice and water shield as good practice.
Neither is better for every home. Shingles cost less up front and suit almost any roof shape. Metal costs more, lasts longer and sheds snow. The best time to choose is before the trusses are ordered, so the roof slope and snow areas can be planned for the material.
The roofing contractor. An Owens Corning extended system warranty is registered by an Owens Corning Preferred Contractor, such as 705 Roofing, after the roof is installed with the required parts.
Yes. An addition, garage or detached building can get the same roofing as the house. Where a new roof meets an older one, the joint is flashed and tied in so water runs from one roof onto the other. Old shingles fade, so a new section may not match an older roof exactly.
