An asphalt shingle roof is a widely used option for protecting homes and buildings from the elements. Made with a fibreglass or organic base coated with asphalt and protective granules, asphalt shingles are popular for their affordability, ease of installation and durability. Their ability to withstand a variety of weather conditions makes them a versatile, economical option for both homes and commercial buildings.

Fibreglass Asphalt Shingles
Most modern asphalt shingles are made with a fibreglass mat coated with asphalt and mineral granules. Lighter than older organic shingles, they also offer good dimensional stability and improved fire resistance.
Options include traditional three-tab shingles and architectural or laminated shingles, which are thicker and provide greater visual depth.
What About Organic Shingles?
Organic-mat shingles are mainly associated with older generations of roofing products and may still be found on some older homes. However, in the Canadian market, fibreglass shingles have replaced them.
When replacing a roof, it is therefore more useful to compare modern shingle products based on their wind and impact resistance, warranty, composition and suitability for local climate conditions.
How Much Does an Asphalt Shingle Roof Cost?
Asphalt shingles are one of the most affordable roofing materials in Quebec. In 2026, you can generally expect to pay $6 to $12 per square foot, including installation. The final cost varies depending on roof size, slope, complexity, shingle type, roof deck, and any additional work required before installation.
For example, a 2,000 sq. ft. roof may cost approximately $12,000 to $24,000, while a 3,000 sq. ft. roof may cost approximately $18,000 to $36,000.
Prices can also increase if several layers of old shingles need to be removed, plywood must be repaired, flashing needs to be replaced, or the roof has multiple slopes, valleys, dormers or chimneys.
Prices vary across Canada because of differences in labour costs, climate, shingle specifications and local market conditions. The following 2026 ranges provide general planning estimates for major Canadian cities:
Major Canadian Market | Approximate Installed Cost |
Toronto / GTA | Approximately $7.50 to $9.90/sq. ft. for architectural asphalt shingles |
Vancouver | Approximately $7.35 to $9.75/sq. ft. for architectural asphalt shingles |
Calgary | Approximately $5.20 to $7.20/sq. ft. for architectural asphalt shingles, with impact-resistant products generally costing more |
Edmonton | Approximately $6.15 to $8.20/sq. ft. for architectural asphalt shingles |
Ottawa | Approximately $7.00 to $9.25/sq. ft. for architectural asphalt shingles |
Halifax | Approximately $5.80 to $7.70/sq. ft. for architectural asphalt shingles |

Benefits
Overall, one of the main advantages of asphalt shingles is that they are widely available and relatively affordable. They are also fairly easy to install, and maintenance requirements are generally limited to minor repairs and an annual inspection.
Drawbacks
Because asphalt shingles are petroleum-based and many products are dark in colour, they can cause the roof surface temperature to climb. In addition, poorly installed shingles can lead to water infiltration and premature deterioration.
How Long Does an Asphalt Shingle Roof Last?
An asphalt shingle roof generally lasts 15 to 25 years, depending on the product, installation quality, and the conditions it is exposed to.
Several factors can accelerate deterioration:
Poor attic ventilation
Repeated freeze-thaw cycles
Strong winds
Significant sun exposure
Snow or ice accumulation
Improper installation
Lack of maintenance
Poor water drainage
Regular inspections can help identify lifted, cracked, or missing shingles, as well as flashing and waterproofing problems, before they become more serious.
Which Colours and Finishes Should You Choose?

Asphalt shingles are sold in a wide range of colours, textures, and finishes. Grey, black, brown, and beige are the most common choices, but some manufacturers also offer shades of blue, green and red.
Architectural shingles can also add depth and, to some extent, reproduce the appearance of materials such as wood or slate.
Before choosing a colour, consider the home's exterior cladding, doors, windows and other architectural features. You should also check applicable municipal regulations, particularly if the property is located in a heritage district.

Here are the general steps involved in installing a shingle roof. Keep in mind that the process may vary depending on your climate, local building codes, as well as other factors.
Follow proper safety measures: Before starting, use appropriate protective equipment, such as a harness and guardrails. Make sure the ladder is stable and that weather conditions are suitable.
Remove the old roofing: Remove the existing shingles and underlayment to inspect the roof deck. Replace any damaged sections to provide a solid base for the new roof.
Install the drip edge: Secure metal edging along the eaves and rakes to direct water toward the gutters and help prevent water infiltration.
Install the underlayment: Roll out the roofing underlayment, starting at the eaves and working upward toward the ridge. This layer provides additional protection against moisture and improves waterproofing.
Apply the starter strip: Install a starter strip or starter shingles along the eaves. This first row helps direct water away from the roof and provides an even base for the following courses.
Install the shingles: Begin laying shingles at the bottom of the roof and work horizontally. Overlap each course according to the manufacturer's recommendations and secure the shingles with the appropriate number of nails.
Install flashing around roof features: Install flashing around chimneys, vents, dormers and other roof penetrations to help prevent water infiltration.
Install ridge cap shingles: Once all the field shingles are in place, install ridge cap shingles along the roof's peak. These specialized shingles protect the ridge from water and provide a finished appearance.

What Roof Pitch Is Required for Asphalt Shingles?
Asphalt shingles are designed for sloped roofs. A 2:12 pitch is generally considered the minimum for this type of roofing.
Additional waterproofing measures may be required, particularly for the underlayment if the slope is between 2:12 and 4:12. Always follow the manufacturer's installation instructions and the requirements applicable to the roofing system being used.
The lower the slope, the more slowly water drains from the roof, and the more important the overall waterproofing system becomes.
Can You Install Asphalt Shingles on a Flat Roof?
No. Asphalt shingles are not designed for flat roofs.
They work as a watershedding system, featuring overlapping courses that rely on slope and gravity to ensure the water glides away from the roof. On a flat surface, water can remain between the shingles and significantly increase the risk of leaks.
For a flat roof, systems designed to provide continuous waterproofing are generally preferred, including:
TPO membranes
EPDM membranes
Certain built-up asphalt roofing systems
How to Maintain an Asphalt Shingle Roof

Inspect your roof once a year to help prevent premature deterioration of your shingle roof. Ideally, the inspection should be performed at the end of winter. Pay particular attention to the condition and adhesion of the flashing, as well as the attic insulation and ventilation. Also, check the shingles for cracks or other visible damage.

How to Repair Damaged Asphalt Shingles
A small number of cracked, torn or lifted shingles can generally be replaced without reroofing altogether.
Ideally, keep a few shingles from the original installation so that future repairs match the existing product and colour.
Repeated damage, leaks, significant granule loss or several areas with warped shingles may indicate a more serious problem. In this case, a professional inspection can determine whether a localized repair is sufficient or whether replacing the roofing material is the better option.
