Rubber roofing, also known as EPDM (ethylene propylene diene monomer), has become increasingly popular for both commercial and residential buildings due to its durability and cost-effectiveness. However, when it comes to repairs, many property owners make critical mistakes that can lead to further damage and expensive fixes down the line. This article highlights the most common rubber roof repair mistakes and how to avoid them.

Rubber Roof Repair Mistakes to Avoid
Using Incorrect Materials
One of the biggest mistakes in rubber roof repair is using incompatible materials. Standard roofing products like asphalt-based sealants can damage EPDM membranes by breaking down the rubber over time. Always use products specifically designed for rubber roofs, such as EPDM-compatible adhesives, sealants, and patching materials. These specialized products ensure proper adhesion and maintain the integrity of your rubber roofing system.
Improper Surface Preparation
Before applying any repairs to a rubber roof, proper surface preparation is essential. Many DIYers skip this crucial step, leading to failed repairs. Always clean the area thoroughly with an appropriate EPDM cleaner to remove dirt, debris, and oils. Any moisture trapped between the repair materials and the roof surface will prevent proper adhesion. Allow the surface to dry completely before proceeding with repairs.
Ignoring Small Problems
Small punctures or tears in a rubber roof might seem insignificant, but they can quickly escalate into major leaks. Water can penetrate these small openings and damage the underlying insulation and deck. Inspect your rubber roof regularly and address even minor damage promptly. Early intervention prevents more extensive and costly repairs later.
Incorrect Application Techniques
Many property owners apply patching materials incorrectly, either using too much or too little adhesive, or failing to properly seal the edges of patches. When applying rubber roof patches, ensure they extend at least 2-3 inches beyond the damaged area on all sides. Press firmly from the center outward to eliminate air bubbles and create a watertight seal around all edges.
Walking on Rubber Roofs Improperly
EPDM roofing can be damaged by improper foot traffic, especially in extreme temperatures. Wearing inappropriate footwear with hard soles or sharp edges can puncture or tear the membrane. If you need to walk on your rubber roof, use soft-soled shoes and walk carefully, avoiding dragging your feet or shifting your weight suddenly.
Neglecting Professional Inspection
While minor repairs can be DIY projects, attempting complex repairs without proper knowledge can cause more harm than good. Have your rubber roof professionally inspected annually and consult with roofing professionals for complex issues or large repair areas. Professional roofers have the tools, materials, and expertise to accurately assess and repair your rubber roof.
Overlooking Flashing Details
The areas where your rubber roof meets walls, chimneys, vents, or other roofing structures are particularly vulnerable to leaks. Many repair attempts fail because these critical flashing details are overlooked. Ensure that all flashing is properly sealed with appropriate rubber roof sealant and that termination bars are secure.

FAQ
How long does a rubber roof typically last?
With proper installation and maintenance, EPDM rubber roofing can last 20-30 years. Regular inspections and prompt repairs of any damage can help maximize its lifespan.
Can I patch a rubber roof in cold weather?
It’s not recommended to apply repairs when temperatures are below 40°F (4°C). Cold weather makes the rubber membrane less flexible and adhesives less effective. For best results, perform repairs on warm, dry days.
What’s the best cleaner to use before repairing a rubber roof?
Use cleaners specifically formulated for EPDM rubber roofing. Avoid petroleum-based products, harsh abrasives, or citrus cleaners as these can damage the membrane. Many manufacturers offer compatible cleaning solutions.
How can I tell if my rubber roof needs repair or complete replacement?
Signs that repair might be sufficient include isolated tears, punctures, or separated seams. Consider replacement if your roof shows widespread deterioration, multiple leaks, significant shrinkage, or if it’s nearing the end of its expected lifespan.
Is it normal for a rubber roof to have small bubbles?
Small bubbles or blisters in a rubber roof often indicate trapped moisture or air beneath the membrane. While not always an immediate concern, these should be monitored as they can grow larger and eventually lead to leaks if left unaddressed.
