Replacing a roof is one of the biggest home improvement investments for Ontario homeowners. Whether your shingles are curling, leaking, or simply reaching the end of their lifespan, planning your roof replacement budget is essential. The total cost depends on your roof size, the materials you choose, labour rates, roof pitch, and the contractor you hire.
If you own a 2000 sq ft home, understanding the current market pricing will help you avoid surprises and choose the best roofing option for your budget. In Ontario, roofing prices have increased slightly due to labour shortages, inflation, and higher material costs, but asphalt shingles still remain the most affordable option.
Below is a clear breakdown of how much it costs to replace a 2000 sq ft roof in Ontario, what affects the price, and how to estimate your exact roofing cost with confidence.
Average Cost to Replace a 2000 sq ft Roof in Ontario:

For a standard 2000 sq ft home, the typical roof size is usually 2,000 – 2,200 sq ft, depending on roof pitch and design.
✔ Average cost in Ontario:
$8,000 – $16,000 (asphalt shingles)
This range includes:
- Removal of old shingles
- Installation of new asphalt shingles
- Labour costs
- Underlayment, ice & water shield, and ventilation
- Disposal of old roofing material
Cost per sq ft
Ontario roofing companies generally charge:
$4.50 – $8.00 per sq ft for asphalt shingles.
So, for a 2000 sq ft roof:
2000 × $4.50 = $9,000
2000 × $8.00 = $16,000
Homeowners with a simple roof fall on the lower side of the range, while homes with steep pitches, multiple valleys, skylights, or chimneys fall on the higher side.
Cost Breakdown by Roofing Material
While asphalt shingles are most common, many homeowners ask how the price compares to other materials. Here’s a breakdown:
1. Asphalt Shingles (Most Popular & Affordable)
Cost:
$8,000 – $16,000 for a 2000 sq ft roof.
This includes:
- Architectural laminates (most common)
- 25–50 year manufacturer warranty
- Fast installation
- Lower repair costs
Asphalt shingles remain the top choice for Ontario due to affordability and good performance in cold weather
2. Metal Roofing
Cost:
$20,000 – $40,000 for a 2000 sq ft roof.
Metal roofing is long-lasting (40–70 years), energy-efficient, and durable, but the upfront cost is significantly higher. Many homeowners compare asphalt vs metal, and in almost every case, asphalt is cheaper upfront.
Which is cheaper?
✔ Asphalt shingles are much cheaper than metal roofing.
3. Cedar Shakes
Cost:
$25,000 – $50,000 for a 2000 sq ft roof.
Cedar offers a luxury look but requires maintenance and is not as common in Ontario.
4. Slate or Premium Roofing
Cost:
$40,000 – $80,000+
Slate is extremely durable but very expensive and typically used on high-end homes.
Factors That Affect the Cost of a 2000 sq ft Roof

Roofing prices vary case by case, depending on several key factors:
1. Roof Pitch & Complexity
Steep roofs (8/12 or higher) cost more due to safety requirements and longer installation times.
- Low-slope: Lower cost
- Medium pitch: Average cost
- Steep & complex roofs: High-end pricing
Homes with many valleys, dormers, skylights, or chimneys require more labour.
2. Tear-Off vs Overlay
Ontario roofing standards recommend complete tear-off, which costs more but lasts longer.
Tear-off adds:
✔ $1,000 – $3,000 depending on layers and disposal fees.
Overlay (installing shingles over old ones) is cheaper but usually not recommended due to warranty limitations.
3. Underlayment & Ice/Water Shield
Ontario’s climate requires:
- Ice & water membrane (mandatory for cold regions)
- Synthetic or felt underlayment
- Drip edge protection
These components add material cost but are critical for preventing leaks and extending roof life.
4. Ventilation
Proper airflow prevents heat buildup and shingle deterioration.
Ventilation upgrades may add:
✔ $300 – $800
5. Roofing Contractor Experience
Hiring experienced roofers may cost more upfront but prevents future repairs and ensures proper installation.
Companies like Professional Roofers follow Ontario Building Code requirements and use certified installation processes, which leads to better long-term results.
How to Estimate Your Roof Replacement Cost
Here are the steps homeowners can follow:
1. Measure Your Roof Size
Roof size is typically 1.1 – 1.3× your home’s square footage to account for pitch and overhang.
For a 2000 sq ft home:
✔ Roof size ≈ 2000 – 2200 sq ft
2. Multiply by Cost Per Sq Ft
Ontario average: $4.50 – $8.00 per sq ft
Example calculation:
2000 sq ft × $6.00 per sq ft = $12,000
3. Add Extra Costs (If Applicable)
- Old roof removal: $1,000 – $3,000
- Wood deck repair: $300 – $2,000
- Skylight replacement: $800 – $1,500 each
- Chimney flashing: $200 – $600
4. Compare at Least 2–3 Quotes
Different contractors include different materials and warranty terms. Price shouldn’t be the only factor always check material quality and installation standards.
How Much Does a Roof Cost on a 1200 sq ft Home?
Since this keyword is relevant, here’s a quick answer:
1200 sq ft roof replacement cost in Ontario:

✔ 30 bundles of shingles (approx.)
What Is the Lifespan of Asphalt Shingles?
The average lifespan in Ontario:
- Architectural shingles: 20–30 years
- Premium shingles: 30–50 years
- 3-tab shingles (older type): 15–20 years
Cold weather, ice dams, and poor ventilation can shorten lifespan.

Conclusion
Replacing a 2000 sq ft roof in Ontario typically costs between $8,000 and $16,000 for asphalt shingles, making it the most affordable and practical choice for most homeowners. The final price depends on your roof’s pitch, design complexity, material quality, underlayment, and the contractor you choose.
