7 Mistakes to Avoid When Installing a Rubber Roof

Rubber roofing, particularly EPDM (Ethylene Propylene Diene Terpolymer) membranes, is known for its durability, flexibility, and ease of installation.

However, even with its straightforward application process, there are common mistakes that can compromise the integrity and longevity of the roof. Here, we outline the most critical mistakes to avoid when installing a rubber roof to ensure a successful, long-lasting installation.

1. Inadequate Surface Preparation
One of the most crucial steps in rubber roof installation is preparing the surface properly. Failing to clean and smooth the substrate can prevent the adhesive from bonding correctly, leading to potential leaks and reduced roof lifespan. Ensure the surface is clean, dry, and free of debris, and consider using a primer if recommended by the manufacturer.

2. Incorrect Adhesive Application
Using too much or too little adhesive can cause issues with the roof’s performance. Applying an even, adequate layer of adhesive is vital for secure bonding. Follow the manufacturer’s guidelines for adhesive application, including the appropriate curing time before laying down the EPDM membrane. Rushing this process can lead to poor adhesion and potential roof failure.

3. Improper Membrane Handling
EPDM membranes are durable but can be damaged if not handled correctly. Avoid dragging the membrane over rough surfaces or sharp edges, which can cause tears or punctures. Additionally, ensure the membrane is stored properly before installation to prevent creasing or other deformities that could affect its performance.

4. Overlooking Seams and Edges
Seams and edges are the most vulnerable parts of a rubber roof. Ensure all seams are overlapped and use the appropriate seam tape and/or adhesive. Pay careful attention to corners and edges, where improper sealing can lead to water infiltration and damage.

5. Ignoring Temperature Guidelines
Installing EPDM roofing in extreme temperatures can affect the QuickBond adhesive’s performance and the membrane’s flexibility. Ideally, install the roof in moderate weather conditions. If you must work in cold temperatures, ensure the adhesive and membrane are kept at a workable temperature, and be aware that adhesive curing times may be longer.

6. Lack of Proper Training
Even though EPDM roofing is relatively easy to install, proper training is essential to avoid mistakes. Investing in professional training can significantly reduce the risk of installation errors. Plytech offers Approved Installer Training programs that provide hands-on experience and detailed knowledge of EPDM installation techniques.

7. Not Using Recommended Tools and Accessories
Using the wrong tools or accessories can lead to improper installation and potential damage. Always use the tools and materials recommended by the EPDM manufacturer to ensure compatibility and optimal performance.
