Choosing a flat roof covering: an important decision
Selecting the right covering for a flat roof can be complex due to the many available options. A flat roof requires special attention and specialized skills to ensure its longevity and efficiency. Engaging professional roofers is essential to ensure that the installation or repair meets the industry's strictest standards.
Popular types of flat roof coverings
In Montreal, where flat roofs are common on residential, commercial, and industrial buildings, four types of coverings stand out: elastomeric membrane, asphalt and gravel roof, TPO membrane (vinyl), and EPDM membrane (synthetic rubber). Each material offers unique characteristics adapted to the varied needs of property owners.
Why choose elastomeric membrane for your flat roof?
Known for its durability and resistance to Quebec's weather conditions, elastomeric membrane can last up to 35 years with minimal maintenance. Its multi-layer design, fused by thermofusion, ensures excellent waterproofing. This choice is very popular in the residential and commercial sectors of Montreal, Laval, and the South Shore.
Advantages of single-ply membranes for flat roofs
TPO and EPDM membranes, although less durable than multi-ply membranes, offer specific advantages. These recyclable coverings are particularly suitable for industrial and green roofs. Their cost is often lower, making them an affordable solution for specific projects while offering good protection against bacteria and mold.
Comparative advantages of multi-ply and single-ply roofs
Multi-ply coverings, such as elastomeric membrane and asphalt-gravel, offer a longer lifespan and increased resistance, but at a higher cost. Single-ply membranes, like TPO and EPDM, are ecological and economical, although they require special precautions to prevent tears or premature wear.
