EPDM Flat Low Slope

Let’s delve into the differences between repairing EPDM (ethylene propylene diene monomer) roofs and asphalt roofs:

1. Material Compatibility:

• EPDM Roof: EPDM is a synthetic rubber roofing material. It’s relatively easy to repair because it can be patched using compatible EPDM materials.
• Asphalt Roof: Asphalt shingles roofs are not directly compatible with EPDM. In fact, EPDM is completely incompatible with solvent-based asphaltic roofing materials like roofing cement or roofing mastic1.

2. Maintenance and Repair:

• EPDM Roof: EPDM roofs are easier to maintain and repair. However, specialized tools and materials may be required for effective repairs.
• Asphalt Roof: Asphalt shingles require regular maintenance and repair to prevent weather damage and leaks. While they are easier to replace than EPDM, the repair process can still be involved2.

3. Durability:

• EPDM Roof: EPDM generally lasts longer than TPO (thermoplastic olefin) and about the same or longer than a similarly-installed PVC (polyvinyl chloride) roof. Well-maintained EPDM roofs can last over 50 years.
• Asphalt Roof: Asphalt shingles are durable but may not match the longevity of well-maintained EPDM roofs13.

In summary, EPDM roofs offer longevity and ease of repair, while asphalt roofs are simpler to replace but require regular maintenance. Remember to use EPDM-compatible materials when repairing EPDM roofs!
