On roofs that are flat or have a very low slope, an EPDM rubber roof is a great option to ensure against leaks from water, or snow. When water sits on a roof, it can easily find ways to enter into your roofing structure. An EPDM rubber roof will prevent these leaks by causing the water to run off the roof. Installing this type of roof system is easy, but will require some time. The roofing will cost $5 to $8 a square foot.
Step 1 - Clean Off the Roof
Before doing anything with your rubber roof, take the time to thoroughly clean the roof. Remove any loose shingles and any debris that has gotten on top of the roof. This could be branches, leaves, rocks, or anything like that. Fill in any gaps in the roof with wood strips. A rubber roof will not hold up to spans of more than 1/4 inch in size.
Step 2 - Roll Out Rubber Membrane
Starting at one side of the roof, roll out the rubber roofing materials. Let is sit on the roof for 30 minutes. After the time has expired, fold the lower half of the rubber strip on top of the upper section and run a broom over the exposed rubber and roof.
Step 3 - Apply Adhesive
Apply the adhesive to both the EPDM rubber roof material and the roof itself with a roller. Carefully fold the membrane back over the section and roll flat. Repeat this process with the other half of the rubber roof. Continue in this manner until you have completed the entire roof.
