🤔 What Is Rubber Roofing?

Rubber roofing, commonly referred to as EPDM (ethylene propylene diene terpolymer), is made from synthetic materials designed to achieve a waterproof and weather-resistant barrier. It is highly durable, can last over 30 years with proper maintenance, and is an eco-friendly choice as it often incorporates recycled materials.

While ideal for flat and low-pitched roofs, rubber roofing is also favored for its UV resistance and ability to withstand extreme temperatures, making it a reliable option for commercial properties.

👉 Preparation is Key

Before installing rubber roofing, thorough preparation is crucial to ensure proper adhesion and to avoid issues like leaks or uneven surfaces in the future.

Key Preparations Before Installation

  • Inspect the Roof’s Surface: Check that the roof deck is completely clean, dry, and free of any dirt, debris, or leftover roofing materials. Any residue or damage left behind can interfere with the rubber’s ability to bond securely.
  • Address Structural Damage: Look for cracks, uneven spots, or water damage on the roof deck. These issues can compromise the integrity of your roofing if not repaired beforehand, leading to long-term structural concerns.
  • Gather Required Tools and Materials: Have everything you need ready to avoid delays. This includes EPDM rubber sheets, adhesive, a roller to smooth the surface, a utility knife for precise cuts, edge trims for finishing, and safety gear like gloves and goggles to protect yourself during the installation.
  • Check Weather Conditions: Choose a day with dry weather and temperatures above 40°F. Wet or cold conditions can prevent the adhesive from bonding properly, which may lead to weak spots or early wear and tear.

🛠️ 7 Steps to Install a Rubber Roof

Installing commercial rubber roofing requires precision and attention to detail to ensure a durable and effective result. By carefully following these seven steps, you can achieve a long-lasting rubber roof that provides excellent protection against the elements.

1. Prepare the Surface

The first step in installing a rubber roof is to prepare the surface properly. Begin by thoroughly sweeping and cleaning the roof to remove all debris, dirt, and dust. Any leftover debris can interfere with the adhesive and the placement of the rubber membrane, compromising the final result. Ensure that the roof deck is completely even, without any dips or bumps, as an uneven surface can cause water pooling over time. Additionally, make sure the roof is completely dry and free from any moisture or grease, as these can weaken the adhesive bond and lead to issues with the membrane’s performance.

2. Measure and Cut Rubber Sheets

Once the surface is ready, roll out the EPDM rubber membrane and measure it against the dimensions of your roof. This step is crucial because precise measurements will ensure a snug and secure fit. Lay the rubber sheet flat and use a measuring tool to mark where it needs to be trimmed. When cutting the rubber sheets, leave a slight overhang along the edges to allow for adjustments and trimming later during installation. This overhang will give you some flexibility as you position the membrane during the adhering process.

3. Apply Adhesive

Applying adhesive is a process that requires care and consistency. Spread the adhesive evenly across the roof surface using a paint roller, ensuring full and uniform coverage. Be careful not to apply too much adhesive, as excess amounts can create lumps under the membrane. Allow the adhesive to sit for a few minutes until it becomes tacky to the touch. This ensures that the rubber membrane will bond properly to the roof without sliding out of place during installation. Take your time during this step, as the quality of the adhesive application can directly affect the durability of your rubber roof.

4. Position and Adhere the Membrane

With the adhesive in place, carefully position the pre-cut rubber sheet over the roof surface. This step requires precision, as the adhesive will create an immediate bond when the rubber sheet is placed down. Begin by aligning one edge of the sheet with the roof, then slowly lay it down across the surface. Use a broom or a roller to smooth out the sheet, starting from the center and working outward. This will help eliminate any air bubbles or wrinkles, ensuring the membrane lies flat and evenly across the roof. Taking your time to achieve a smooth finish is essential for a professional and watertight installation.

5. Seal Seams

Where two rubber sheets meet, it is critical to seal the seams properly to create a watertight barrier. Use seam tape and adhesive to join the sheets together securely. Apply the adhesive to the overlapping edges and press down firmly with a roller or seam tool to create a strong bond. Sealing the seams correctly prevents water from seeping through the roof, which is vital for the long-term performance of the rubber roofing. Double-check all seams for any gaps or loose areas and make adjustments as needed to ensure a perfect seal.

6. Trim Excess Material

Once the rubber membrane is adhered and all seams are sealed, trim any excess rubber along the edges of the roof. Use a utility knife or sharp scissors for a neat and precise cut. Trimming not only improves the appearance of the roof but also prevents the overhanging material from flapping in the wind or collecting debris over time. To further enhance the durability of your roof, install edge trims along the perimeter. These trims provide additional protection and give the roof a polished and professional finish.

7. Install Flashing

The final step in the installation process is to apply flashing to vulnerable areas of the roof. Flashing is essential for protecting edges, corners, and areas around vents or other roof penetrations where leaks are most likely to occur. Carefully apply the flashing, ensuring it is securely bonded to the surface. Inspect all seams and edges to confirm they are fully sealed and watertight. By addressing these critical areas, you can prevent future leaks and extend the life of your rubber roof.

🚫 Common Mistakes to Avoid

Avoiding common mistakes during rubber roof installation is crucial for ensuring durability and preventing leaks. Proper installation saves time, money, and costly repairs in the future.

  • Skipping Roof Preparation: Failing to clean and repair the roof surface before installation prevents the adhesive from bonding properly. Dirt, debris, or cracks left untreated can weaken the roof and lead to premature issues.
  • Applying Adhesive Incorrectly: Adhesive must be applied evenly to avoid air pockets, which can cause water pooling and compromise the roof’s integrity over time. Proper attention to detail during this step is essential for a long-lasting seal.
  • Overlooking Seams: Seams are a vulnerable point in any rubber roof. Improper sealing or not double-checking the seams can allow water to seep in, leading to leaks and water damage over time.
  • DIY Errors: While it may seem cost-effective to oversee or attempt installation yourself, rubber roofing requires expertise. Hiring professionals ensures proper installation and reduces the risk of expensive mistakes.
