How to Install a Rubber Roof Membrane Around Posts
- 1). Prepare the surface of the roof by rinsing away any loose dirt or debris. Then follow up with a high grade roof cleaner.
- 2). Unroll the EPDM rubber and allow it flatten for 30 minutes. The material will be easier to manage once it has relaxed.
- 3). Use measuring tape to get the diameter of the top and base of each metal post. This will determine the size of the holes that you'll need to cut into the rubber.
- 4). Measure the surface area of the rooftop and use the scissors to cut sections of the rubber into manageable sizes. Use chalk to draw the larger of the two diameters (top or base) of each post onto the rubber.
- 5). Indicate the diameter in the form of crosshairs, then draw a complete circle to the best of your ability. It is most important that the sheet of rubber fits over the post.
- 6). Stir the can of neoprene liquid adhesive with the application brush for at least five minutes. Fold back each section of rubber and apply it to both the backside and onto the surface of the roof itself in order to reinforce the bond.
- 7). Permanently press the EPDM rubber sheets over the posts and onto the surface of the roof. Flatten any wrinkles and air bubbles with a roller or push broom depending on the size of your roof.
- 8). Apply the seam tape to the spaces between each sheet of rubber in order to insulate the roof. Allow the EPDM rubber to completely cure in a dry climate for 48 hours.
