Are you thinking of redoing your roof and metal roofing has caught your eye? It's a material increasingly chosen in Quebec, and for good reason. Before making a decision, it's still worth weighing the pros and cons, because metal roofing isn't the right choice for everyone in every situation.
Here's what you need to know to make your decision.
The best reason to choose a metal roof, is its longevity. A properly installed metal roof lasts between 40 and 70 years, compared to 15 to 25 years for standard asphalt shingles. This means a single replacement can cover the entire lifespan of a house, completely changing the long-term calculation.
Maintenance is also much less demanding. Metal roofing doesn't crack or warp, and its smooth surface naturally sheds snow. There's no need to replace sections after every harsh winter; periodic cleaning and a few inspections are enough to keep it in good condition for decades.
In terms of durability, the Association des consommateurs pour la qualité dans la construction (ACQC) confirms that metal roofs are renowned for their exceptional longevity in extreme weather conditions.
For comfort, metal reflects some of the sun's rays, which helps stabilize indoor temperatures in summer and reduce air conditioning bills. And for safety, Natural Resources Canada recommends metal tiles as fire-resistant roofing materials to enhance homes' resilience against fires.
While metal roofing is strong, it's not without its limitations. The first hurdle for many homeowners is the upfront cost of installation: metal roofing is more expensive than asphalt shingles initially. This difference often evens out in the long run, but you need to have the budget available from the start.
Noise is another reality to anticipate. Without adequate acoustic insulation beneath the roofing, rain on metal can be heard more distinctly indoors, and this is one of the most frequent complaints from homeowners who skipped this step. The good news: properly installed insulation usually solves the problem during the initial installation.
Thermal expansion can also cause surprises. Metal expands and contracts with temperature changes, and if panels aren't properly secured, noises or slight movements can appear over time. The same applies to warping: panels installed on uneven supports can form waves or bumps on the surface. Choosing thicker panels and working with an experienced roofer significantly reduces these risks.
Specialized installation is perhaps the least visible drawback, but it often has the most impact. Installing a metal roof requires skills that not all roofers possess. Poor initial workmanship can lead to problems for years.
First and foremost, have your current roof inspected by a qualified roofer. Depending on its condition, you might still have a few good years left. There's no need to rush a decision of this magnitude.
When it's time to request quotes, ask specific questions about the insulation planned for under the metal roofing. This detail, often overlooked, will make all the difference in terms of noise and thermal performance. And be sure to compare roofers who regularly work with this material, not just with shingles. Specific experience with metal truly changes the final outcome.
Once installed, metal roofing is low-maintenance.
After major storms, a quick check around flashings and seams is enough to detect a problem before it worsens. It's also worth removing branches or debris that accumulate, as they trap moisture against the metal. Keep your gutters clear so that meltwater drains properly, and consult a roofer as soon as you notice a discolored, warped, or suspicious area: it's better to act early.
Metal roofing is one of the most robust coverings for Quebec homes. Its longevity, weather resistance, fire-retardant properties, and low maintenance make it a solid investment for those thinking long-term. The points of vigilance (initial cost, acoustic insulation, installation quality) are all manageable with the right professionals.
