When it is time to replace a roof, one question comes up again and again: should you stick with asphalt shingles or switch to a metal roof? Both are common on homes and chalets in the Laurentides, and both can perform well in a cold, snowy climate when installed correctly.
The right choice depends on your home, your budget, how long you plan to stay and the look you want. This guide compares the two options on the points that matter most for Quebec winters.
Asphalt shingles: the familiar choice
Asphalt shingles are the most common residential roofing material in Quebec. They consist of a fibreglass mat coated with asphalt and topped with mineral granules that protect against UV rays and give the shingles their colour.
Advantages of asphalt shingles
- Lower upfront cost than most metal roofing systems
- Many roofers are experienced with installation, which makes scheduling easier
- Wide choice of colours and styles, including architectural shingles with a dimensional look
- Repairs are usually simple, since individual shingles can be replaced
- Quiet under rain and hail
Disadvantages of asphalt shingles
- Shorter lifespan than metal
- More vulnerable to wind uplift, granule loss and ageing from sun exposure
- Snow tends to stay on the roof longer, increasing the importance of good attic ventilation to limit ice dams
- Moss and algae can grow in shaded, humid areas, which is common under trees in the Laurentides
Metal roofing: the long-term investment
Metal roofs are made of steel or aluminum panels or shingles with protective coatings. The most common types for homes are standing seam panels and metal shingles designed to look like traditional materials.
Advantages of metal roofing
- Long lifespan when properly installed and maintained
- Snow slides off more easily, reducing the load on the structure
- Resistant to rot, moss and many types of weather damage
- Lightweight compared to many other roofing materials
- Can be recycled at the end of its life
- Modern, clean look that suits contemporary homes and chalets
Disadvantages of metal roofing
- Higher upfront cost
- Requires installers with specific expertise; a poor installation can lead to leaks at seams and fasteners
- Snow sliding off the roof can be dangerous near entrances, walkways and parked cars, so snow guards are often needed
- Can be noisier during rain if there is little insulation or no solid deck beneath
- Dents are possible with some thinner panels in severe hail
How each performs in Quebec winters
Snow load and shedding
Metal roofs shed snow more readily, which is a real advantage in areas with heavy snowfall. However, large sheets of snow can fall all at once. Plan snow guards over doors, decks and walkways.
Shingle roofs hold snow longer. That is not a problem in itself, as long as the structure is designed for local snow loads and the attic is well insulated and ventilated.
Ice dams
Neither material is immune to ice dams. The main cause is heat escaping into the attic. Good insulation, air sealing and ventilation are essential whatever roof covering you choose. Our guide on common causes of roof leaks explains how water can find its way into the house.
Freeze-thaw cycles
Repeated freezing and thawing stresses roofing materials. Quality installation, proper flashing and a waterproof membrane at the eaves and in valleys help both types of roof last longer.
Comparing other key factors
Appearance and neighbourhood rules
Some municipalities or neighbourhood associations have rules regarding roof colours or materials, especially in heritage areas. Check with your municipality before choosing.
Resale value
A newer roof in good condition is an asset when selling a home, whatever the material. Buyers often appreciate the durability of metal, while shingles remain a familiar and accepted choice.
Maintenance
Both roofs require periodic inspections. Shingle roofs need attention to damaged or missing shingles and moss. Metal roofs need checks on fasteners, seams, sealants and flashing.
How to decide
Ask yourself these questions:
- How long do you plan to stay in the home? A longer horizon can justify the higher initial cost of metal.
- Is your roof shaded and humid, or exposed to strong winds?
- Do you have entrances, decks or driveways where sliding snow could be a hazard?
- Does your roof structure have any condition issues that need to be addressed first?
- What look do you want for your house or chalet?

Get a roofing quote
Prices vary a lot depending on the size and slope of your roof, its complexity, the condition of the deck and the material you choose. The best way to compare is to request detailed quotes for both options.

FAQ: asphalt shingles vs metal roofing
Is a metal roof louder than shingles?
A metal roof installed over a solid deck with proper insulation is usually not much louder than shingles inside the home. Noise is more noticeable on structures with little insulation, such as sheds or open porches.
Can a metal roof be installed over existing shingles?
In some cases, but it depends on the condition of the existing roof, local building rules and the manufacturer’s instructions. A roofer should inspect the deck before recommending this approach.
Does a metal roof attract lightning?
Metal roofs do not attract lightning more than other materials. If lightning strikes, a metal roof is non-combustible.
Which roof is better for a chalet in the Laurentides?
Many chalet owners choose metal for its snow shedding and durability, especially for chalets that are not occupied all winter. Shingles remain a good option for smaller budgets.
Do I need a permit to replace my roof?
Requirements vary by municipality. Some require a permit for any roof replacement or change of material. Check with your municipality before starting work.
