Understanding EPDM Roof Bubbles

EPDM (ethylene propylene diene terpolymer) roofing is a popular choice for commercial and residential buildings due to its durability and cost-effectiveness. However, one common issue that can arise with EPDM roofs is the formation of bubbles. These bubbles can be caused by a variety of factors such as poor installation, trapped moisture, or extreme weather conditions. While these bubbles may not always lead to immediate leaks, they can cause problems over time if not properly addressed.

Assessing the Situation

If you notice bubbles forming on your EPDM roof, the first step is to assess the situation. Are the bubbles small or large? Are they scattered across the roof or concentrated in one area? It’s important to determine the extent of the problem before deciding on the best course of action.

Dealing with Small Bubbles

If the bubbles on your EPDM roof are small and relatively few in number, they may not require immediate attention. Small bubbles are often caused by air trapped during installation and may not necessarily lead to leaks. In these cases, monitoring the bubbles for any changes and ensuring proper roof maintenance can help prevent any future issues.

Repairing Large Bubbles

Large bubbles on an EPDM roof can be a more serious problem as they are more likely to trap moisture and eventually lead to leaks. Repairing large bubbles involves several steps:

1. Clean the area: Use a broom or brush to remove any debris or dirt around the bubble.

2. Make an incision: Carefully cut a small slit at the base of the bubble to release any trapped air or moisture.

3. Apply adhesive: Lift the EPDM membrane and apply a specialized adhesive to the roof substrate. Press the membrane back down firmly to ensure a proper seal.

4. Roll the area: Use a seam roller to ensure the membrane is securely bonded to the adhesive and substrate.

Preventing Future Bubbles

Proper installation is key to preventing EPDM roof bubbles. Hiring experienced professionals and ensuring the roof is properly prepared before installation can help minimize the risk of bubbles forming. Additionally, regular roof inspections and maintenance can help catch any potential issues early on and prevent them from escalating.

By understanding the causes of EPDM roof bubbles and taking proactive measures to address them, you can ensure your roof remains durable and leak-free for years to come.
