- 1). Clean the roof surface of all shingle debris and nails. Re-fasten any loose roof boards.
- 2). Fill any gaps larger than 1/4 inch with wooden strips. The EPDM cannot span gaps of more than 1/4" without risk of failure.
- 3). Start at the bottom of the roof and roll out the EPDM from one side of the roof to the other and let it sit for 30 minutes. Fold bottom half of the membrane onto the top half and use a broom to sweep the exposed roof deck and EPDM membrane.
- 4). Apply the adhesive to both the exposed roof deck and the EPDM membrane using a roller. Slowly fold the EPDM roofing membrane back into place. To ensure a good bond, use a stiff bristled push broom and force the membrane into contact with the roof deck. Repeat the process on the other half of the EPDM membrane.
- 5). Roll out the next piece of membrane, allowing a six inch overlap on the piece below it. This overlap is crucial to allow proper adhesion between the two pieces and to allow the water to flow from the upper part of the roof down to the roof edge.
- 6). Adhere this section in the same manner as the first section. Continue adding sections until you have covered your roof.
