New Roof Installation
GAF CERTIFIED ROOFING CONTRACTOR • 15+ YEARS GTA EXPERIENCE
YS Roofing installs roofing systems on new residential builds, additions, and custom homes across Toronto and the GTA, working from a written proposal that sets the material, scope, and price before installation begins. Builders and general contractors coordinating a project are welcome to reach out to discuss scope and scheduling. Every job starts with a free estimate based on the building plans, confirmed on site once framing is up.
Signs You Need New Eavestroughs
■ New Home Construction
A new home under construction that has reached the point where the roof deck is ready for a roofing system
■ Custom Home Builds
A custom home build where the roofing material and detailing are being chosen alongside the rest of the exterior finishes
■ Home Additions & Extensions
A home addition, second storey, or garage that needs its own roof section tied into the existing structure
■ Teardowns & Rebuilds
A rebuild following a teardown, where the new structure needs a full roofing system from the start
■ Commercial & Mixed-Use Builds
A commercial or mixed-use new build requiring a roofing system suited to the building type
What Is Included
- Installation of the roofing system chosen for the project, whether asphalt shingle or flat roofing, matched to the roof design and slope
- Ice and water shield, underlayment, flashing, and ventilation components installed as a complete system rather than added piecemeal
- Coordination with the builder’s schedule, since a new roof typically has to go on before interior work can proceed under a weathertight structure
- A written scope and price set from the plans, with any adjustment once actual site conditions are confirmed
- Site protection and full cleanup before the crew leaves
How the Job Runs
- Consultation. We review the building plans, discuss material and system options, and confirm timing with the build schedule.
- Detailed Proposal. A written scope covering the roofing system, materials, and price, based on the plans and confirmed once the deck is ready.
- Professional Installation. The crew installs the roofing system to manufacturer specification once the structure is ready to receive it.
- Final Inspection. A walk-through confirming the completed roofing system and site cleanup before the crew leaves.
What Most Homeowners Get Wrong
The most common mistake is leaving the roofing system as an afterthought in the build schedule, when it is actually a gating item: interior trades generally cannot proceed with confidence until the structure is weathertight. A second mistake is choosing a roofing material late in the process without checking it against the roof’s actual slope and design, since some systems are not suited to every pitch. A third is assuming a new roof does not need the same ventilation planning as a replacement; a new build with poor attic or roof assembly ventilation can develop the same moisture and ice damming problems as an older home, just sooner, if intake and exhaust airflow are not planned in from the start.
GTA Conditions That Matter
New construction in the GTA still has to be built for the same freeze-thaw cycling, ice damming risk, and spring wind exposure that affects every other roof in the region, so a new roofing system is not exempt from the local detailing that a replacement roof needs: proper ice and water shield at eaves and valleys, manufacturer-specified fastening for wind resistance, and a ventilation path that works with the home’s actual insulation plan rather than a generic assumption carried over from the framing drawings.

A written proposal before installation and a final inspection before the crew leaves apply to new construction the same way they apply to a full roof replacement.
FAQ
Do you install roofs on new home construction?
Yes. YS Roofing installs roofing systems on new residential builds, additions, and custom homes across Toronto and the GTA, working from the building plans and coordinating with the build schedule.
Do you work with builders and general contractors?
Builders and general contractors coordinating a roofing scope on a new-construction or addition project are welcome to contact us directly to discuss the project, timing, and a written proposal.
How much does new roof installation cost?
Cost depends on the roof size, pitch, design complexity, and material chosen. We do not publish a price online because these variables change the total meaningfully from project to project. A free estimate based on the plans gives a written figure, confirmed once the deck is ready.
Can you install a roof on a home addition without redoing the whole roof?
Yes. An addition or second-storey roof section can be tied into the existing roof, matching material and detailing where the two meet. This is assessed during the estimate.
Does a new roof need the same ventilation planning as a roof replacement?
Yes. Attic or roof assembly ventilation matters as much on new construction as it does on a replacement, since poor airflow can lead to moisture and ice damming issues over time regardless of how new the roof is.
