One secret to a long-lasting rubber roof is prepping the surface properly before you install it. When all of the new Dicor roofing supplies arrived, it was time to install the new rubber roof on the project trailer.
Here’s how we did it. Make sure all of the roof seams are as tight and as level as possible. All of the screw heads need to be level or slightly below the surface of the roof decking. If any of the seams are wider than 1/16 of an inch, you can apply seam tape to cover the seams and the screw heads. To avoid any sharp edges from damaging the roofing membrane, you can either bevel the edge of the roof decking using a sander or you can use fleece tape over the edges. Next, sweep and/or blow compressed air over the entire roof prior to starting on the installation.
After you measure the roof, cut the roofing membrane to fit. Be sure and allow some excess on the ends and the sides that can be trimmed later. Lay the roofing membrane over the roof and make sure the excess is evenly spaced at the front and rear and side to side. Fold the membrane in half, exposing the roof decking on one half. Apply the adhesive, using a roller attached to a handle. Carefully roll both ends of the membrane over the adhesive, trying to avoid any wrinkles. Now fold the other side back and repeat the process. Finish by sweeping out any air bubbles in the roofing membrane, starting in the middle of the roof and working towards the sides.
