Elastomeric Membrane

Elastomeric coatings stand out for their stability, resistance to extreme weather conditions, and energy efficiency. Used in various construction applications, they provide a reliable barrier against moisture and water infiltration while reducing maintenance costs.

White elastomeric membranes reflect sunlight, helping to mitigate urban heat islands and lower cooling expenses during summer. These benefits make them an excellent choice for roofing projects.

What Is an Elastomeric Roofing Membrane?

An elastomeric membrane is a waterproof roofing material designed to withstand extreme temperatures and ensure long-lasting durability. Made from a rubber-like polymer, it is manufactured in rolled sheets for easy installation.

This roofing system is particularly suited for flat and low-slope roofs and is available in two primary types:

Traditional Elastomeric Membrane

Also known as modified bitumen membrane, the traditional elastomeric membrane is installed using torches. This heat-sealing method ensures seamless waterproofing by fusing the joints together.

Composed of two layers:

  • The base layer provides adhesion to the roof structure.
  • The top layer serves as the finishing coat, ensuring long-term durability.

Once fused, these layers create a highly durable, waterproof barrier. Due to its robustness, this membrane is commonly used on large flat roofs.

Self-Adhesive Elastomeric Membrane

Unlike the traditional method, the self-adhesive elastomeric membrane is installed without the use of torches, making it a safer, cold-applied solution.

This cold application method allows for a quicker, more secure installation while maintaining excellent waterproofing performance. It is particularly beneficial for projects where fire safety and speed are top priorities.

Advantages and Disadvantages of Elastomeric Membranes

Superior Leak Protection

Elastomeric membranes offer exceptional waterproofing, significantly reducing the risk of water infiltration—a common issue for flat roofs. This enhances building protection and longevity.

UV and Heat Resistance

These membranes withstand high temperatures and UV exposure. Reflective coatings, such as white membranes, help lower cooling costs by reducing heat absorption.

High Tear Resistance

Reinforced with fiberglass or polyester layers, elastomeric membranes resist tearing and can endure foot traffic without damage.

Easy Installation

Available in roll form, elastomeric membranes are straightforward to install and provide seamless coverage.

Weatherproof Durability

Designed for year-round weather resistance, they offer excellent performance against temperature fluctuations, rain, snow, and wind.

Extended Lifespan

When properly installed, elastomeric membranes last over 30 years, making them a cost-effective investment for flat and low-slope roofs.

Minimal Maintenance

Compared to other roofing materials, elastomeric membranes require little upkeep. An annual inspection is recommended, and minor damages can be repaired using bitumen patches.

Potential Drawbacks

Despite their many benefits, elastomeric membranes have a couple of downsides:

  1. Fire Risk During Installation
    Traditional elastomeric membranes require torch application, increasing the risk of fire hazards. While self-adhesive options exist to mitigate this risk, it is essential to hire a contractor with proper fire safety insurance.
  2. Non-Recyclable in Quebec
    Elastomeric membranes are not currently recycled in Quebec, which poses an environmental concern.

Installation and Maintenance of Elastomeric Roofing Membranes

Installation Guidelines

Before installation, proper roof surface preparation is essential:

  • The roof must be clean, dry, and free of debris to ensure strong adhesion.
  • The membrane’s flexibility allows for seamless installation in any season, whether in warm or cold weather, without compromising performance.

Routine Maintenance for Longevity

To maximize its lifespan, biannual inspections are recommended:

  • Spring and fall check-ups, along with post-storm inspections, help detect and repair potential damage early.
  • Special attention should be given to drains, gutters, flashing, joints, folds, and bubbles in the membrane.

Drainage System Maintenance

During inspections:

  • Clear drains and remove debris to prevent blockages that could cause water accumulation and damage.
  • Ensure gutters and downspouts remain unclogged for efficient water drainage.

Winter Roof Management

In snowy regions, removing excess snow prevents structural overload. Professional snow removal is advised to avoid tearing the membrane. Expert roofers have the proper equipment and knowledge to safely clear flat roofs without causing damage.

Why Choose an Elastomeric Roof for Your Project in Montreal?

Elastomeric roofing is an ideal choice for flat roofs in Montreal, offering superior durability and resistance to the city’s fluctuating climate. This high-performance roofing material, often applied using a torch, ensures optimal waterproofing and protection against moisture-related damage.

A Modern Alternative to Traditional Shingles

While asphalt shingles remain a popular roofing option, elastomeric membranes provide a more advanced solution for renovations and new construction projects involving flat roofs. If you’re looking for a long-lasting, high-quality roofing material, elastomeric membranes exceed expectations.

A Cost-Effective and Reliable Solution

Although elastomeric roofing may have a higher initial cost compared to asphalt shingles, its excellent long-term value results in fewer repairs and lower maintenance expenses.

Additionally, in Montreal, hiring an experienced roofing contractor ensures a high-quality installation, maximizing the membrane’s lifespan and performance.

Designed for Flat Roof Challenges

Flat roofs face several challenges, including:

  • Drainage issues
  • Snow accumulation
  • Extreme temperature variations

An elastomeric membrane, applied with a torch, provides a durable and weather-resistant solution to overcome these challenges.
