Average Price to Replace an Asphalt Shingle Roof In Ontario
What is the average cost to replace an asphalt shingle roof in Ontario? The average cost to replace an asphalt shingle roof in Ontario typically ranges from $5,000 to $15,000, with most homeowners paying between $7,000 and $12,000 depending on roof size, materials, and complexity. Larger or more complex roofs may exceed this range.
Understanding what goes into that price is key. Labour, tear-off and disposal, underlayment, ventilation, and roofing accessories all influence the final cost. Ontario’s climate and building requirements can also impact installation methods and pricing.
In this guide, we break down the average cost of roof replacement in Ontario, including price per square foot, key cost drivers, and what homeowners can expect when planning a roofing project.
Roof Size
The overall size of the roof contributes to the price of replacing a roof for many reasons. The larger the roof, the more material it requires. It will also take longer to reconstruct the roof, thus adding to the labour cost.
Inclination
The roof pitch plays an important factor since the steeper the roof, the more difficult it is to work on. Additional safety equipment is required as the inclination increases to ensure all contractors are well protected. As well, materials cannot be stacked on higher pitched roofs thus adding a degree of complication to the project.
Accessibility to the Roof
Roofs that are not easily accessible and require special equipment to transport roofers and materials onto the roof will increase labour hours as well as equipment cost.
Type of Shingle
The most popular shingles are the ones made with asphalt. They are versatile, affordable and easy to install compared to other materials. Asphalt shingles come in 2 styles: 3-tab & architectural. The 3-tab shingles, which is the most widely used and least expensive, is very flat and have cut-outs along the bottom edge, making it look 3 separate pieces. On the other hand, the architectural style gives a 3-dimensional look and is heavier and more durable.
Considering the factors listed above, asphalt shingle roof replacements for residential properties range as follows:
| Size in Square Feet | Typical Price Range |
| 500 -1000 | $2,100 - $4,700 |
| 1500 – 2500 | $6,000 - $11,800 |
| 2500 – 3500 | $9,400 - $16,400 |
| +4000 | $16,500+ |
In general, pricing usually includes the removal and disposal of 1 layer of old shingles as well as any underlayment, accessories and necessary building permits.
Noteworthy items:
- Hire only insured roofing contractors. Using uninsured contractors mean all liability will be transferred to the homeowner in the event the worker is injured, property is damaged and/or the home insurance policy will no longer be valid.
- Roof replacement estimates that are unusually lower than other roofing companies may be an indication of uninsured roofers, inexperience or uncertified contractors.
- Check reviews from past customers of the roofing company. Make note of projects similar to your request and the corresponding testimonials.
