Ontario shingle roofing — by the numbers
Architectural shingles carry manufacturer warranties of up to 50 years under proper installation conditions.
The Ontario Building Code requires ice and water shield to extend at least 900 mm beyond the interior wall line at eaves — a standard MKT always exceeds.
A typical 1,800 sq ft Ontario home has roughly 20–24 roofing squares — the standard unit for material and labour estimation.
Shingle types compared
| Shingle type | Lifespan | Cost range (avg. home) | Best for |
|---|---|---|---|
| 3-Tab asphalt | 15–20 years | $6,000–$12,000 | Budget-conscious projects |
| Architectural asphalt | 25–30 years | $8,000–$16,000 | Most Ontario homeowners |
| Impact-resistant asphalt | 25–30 years | $10,000–$18,000 | Wind / hail-exposed areas |
| Rubber (TPO/EPDM) | 30–40 years | $10,000–$18,000 | Complex geometry, cold climates |
| Cedar | 30–35 years | $14,000–$24,000 | Aesthetics, heritage properties |
| Metal shingles | 40–50 years | $18,000–$30,000 | Long-term value, cottages |
Cost ranges are estimates for a typical Ontario home (1,800–2,200 sq ft, standard pitch). Final price depends on roof complexity, decking condition and access.
Signs your shingles need attention
- Curling, cupping or cracking — common after 15–20 years of freeze-thaw cycling
- Granule loss in eavestroughs — UV breakdown accelerating toward failure
- Missing shingles or exposed decking after wind events — infiltration risk within 24–48 hours
- Recurring interior leaks that can’t be traced to a single entry point
- Visible sagging, soft spots or interior staining below the roofline

As a GAF Certified Preferred Contractor, we’ve met the strict criteria of one of Canada’s leading shingle manufacturers, and we keep that standing through ongoing training in the GAF learning program.

Frequently asked questions
What is the difference between 3-tab and architectural shingles?
3-tab shingles are flat and uniform — the entry-level option. Architectural (laminated) shingles are thicker, dimensionally varied and carry warranties up to 50 years. Most Ontario homeowners now specify architectural for the combination of looks and durability.
How long does shingle installation take?
Most residential re-roofs complete in one to two days depending on size, pitch and weather. We provide a clear schedule before starting.
Can you repair a few shingles without replacing the whole roof?
Yes — targeted repair is the right call when damage is isolated and surrounding shingles are structurally sound. We match existing profiles and colours as closely as possible.
What shingle brands does MKT Roofing use?
GAF and Owens Corning exclusively — two of North America’s most trusted manufacturers, with industry-leading warranty programs transferable to future homeowners.
Does ice and water shield make a difference in Ontario?
Significantly. Ontario’s freeze-thaw cycles and ice damming create conditions where standard underlayment is insufficient at the eaves and valleys, so we always install self-adhering ice and water shield well beyond the code minimum.
