Flat Roof Lifespan: The Importance of Materials & Maintenance

Flat roofs are a popular choice for both residential and commercial buildings in Montreal, thanks to their modern look and efficient use of space. However, the lifespan of flat roofs varies according to the materials used and how well you take care of it. To better understand this, René Perron Couvreur offers you this comparison of flat roof materials and provides key maintenance tips that can help extend your flat roof’s lifespan.

Asphalt and Gravel 

Asphalt and gravel roofs have been a traditional choice for decades. Their lifespan generally ranges from 15 to 20 years, but with proper maintenance, they can last up to 25 or even 30 years. The gravel layer protects the asphalt membrane from UV rays and extreme weather, but it’s crucial to ensure the gravel stays evenly distributed. Over time, asphalt can dry out and crack, so regular inspections and timely repairs are key to extending its life.

Elastomeric Bitumen Membrane

Elastomeric bitumen membranes are a more modern alternative to asphalt and gravel. They typically last between 25 and 30 years and sometimes longer with diligent maintenance. These membranes are flexible, resistant to temperature fluctuations, and easier to repair than asphalt roofs. Regular biannual inspections to check for punctures or seams coming loose will help you get the most out of this roofing system.

White Flat Roofs

White roofs are gaining popularity because they reflect sunlight, reducing heat absorption and energy costs. These roofs often use materials like TPO or PVC membranes, which can last 20 to 30 years. Their reflective properties not only improve energy efficiency but also help protect the membrane from UV degradation, contributing to a longer lifespan.

Tips to Maximize Your Flat Roof’s Durability

At René Perron Couvreurs, we emphasize that proper maintenance is just as important as choosing the right material. Here are some expert tips to help your flat roof reach or exceed its expected lifespan:

• Schedule regular inspections: Aim for at least twice a year - in spring and fall - to catch minor issues before they become costly problems.
  

• Ensure proper drainage: Standing water is the enemy of flat roofs. Make sure drains and scuppers are clear of debris to prevent pooling. 
  

• Maintain protective layers: For asphalt and gravel roofs, keep the gravel layer intact to shield the membrane from sun damage.
  

• Clean your roof: Remove leaves, dirt, and other debris regularly to avoid clogged drains and surface wear.
  

• Choose quality materials and professional installation: Investing in high-quality membranes and expert installation pays off in the long run.
