Seams and existing patches
Cleaning, primer and the specified compatible repair materials affect adhesion. Failed earlier patches complicate the connection.

Get help with EPDM rubber roof seams, flashing details and repair or replacement decisions.
EPDM is a rubber roofing membrane. Its seams, patches and flashing details use compatible materials and preparation methods that differ from TPO welding. A loose seam or a failed penetration needs a sound repair connection, not a generic coating spread over the symptom.
We look at existing patches, surface condition, edge attachment and drainage along with the reported leak. If water has reached insulation, the repair may need material opened and replaced below the membrane. A dry top surface does not rule out moisture underneath.

A rubber roof needs room to remain securely connected at transitions while the membrane changes with temperature and age. The detail around a curb can demand different work from an open seam across the field.
Cleaning, primer and the specified compatible repair materials affect adhesion. Failed earlier patches complicate the connection.
Flashings and terminations hold the system where the continuous membrane is interrupted. Loose attachment or deteriorated details need correction.
System area, seam work, wet insulation, attachment and access determine the cost. A residential shingle price does not establish a budget for this roof.

The roof system, the room below the leak and the access route all affect the work. Start the building's repair or restoration plan with a free roof walk.
