EPDM roof coating turns a black rubber roof white and seals its seams under a new film. EPDM is a tough membrane, and a lot of commercial buildings in Moscow, ID still have the original sheet on them. The problems show up at the seams and at the edges as the rubber shrinks with age.
Seam tape and old adhesive let go first. Then flashings pull tight at the walls and corners, which is called bridging, and the membrane can tear there. We fix those spots first: open seams get cleaned and re-taped, bridged flashings get relieved and patched, and punctures get covered.
EPDM needs a specific primer before any coating will bond. The surface also has to be scrubbed clean of the oxidized layer, because coating over chalk is coating over dust. We test adhesion on your roof before we spray the field.
After prep, an EPDM roof coating system in Moscow, ID is usually silicone or a coating made for rubber roofs, applied in one or two passes with fabric at the seams. The roof goes from black to white, which cuts heat soaked up by the deck. Also see ponding water repair if water sits on your roof. Call (833) 441-4944.
