Ethylene propylene diene monomer (EPDM) is a synthetic rubber membrane that offers extreme durability. An EPDM roof is designed to provide protection for a lengthy period, while also offering insulating benefits.

Deciding to repair or replace your roof depends on the type of damage and the installation. Ballasted installation, mechanical attachment or fully adhered installation systems are typically used.

When to Repair Your EPDM Roof

Ballasted or mechanically attached EPDM roofing systems are easier to remove in sections. If your roof only has damage in a small section, having that area repaired is the best choice. Sealants and adhesives, specifically designed for EPDM roofs, will be used to provide a quality repair. Patches are designed to install over defective sections, however this work is best left to professionals.

On a ballasted or mechanical installation, an entire section can be removed and replaced if required. In fully adhered applications, patching and sealing is the recommended repair procedure.

When to Replace Your EPDM Roof

If the membrane has become contaminated through the use of the wrong repair products, all of the EPDM material will require replacement. This situation occurs if asphalt-based products or roofing cements are used to attempt a repair.

If your roof is nearing the end of its expected useful life, has been subject to significant damage or the cost of repairs is close to that of a new EPDM roof, you should consider roof replacement. Get a professional roof inspection to determine the amount of damage to your existing roof and weigh the costs of repairs or replacement.

You can select an EPDM roof for both new and existing roofing projects. This material is an excellent choice for low sloping, commercial applications. Warranties are available that range from five to 30 years with additional options for hail or puncture damage.
