Learn How To Install A Rubber Membrane Over Your Tool Shed’s Leaky Roof

If your tool shed has a leaky roof, installing a rubber membrane over it can be beneficial. A rubber membrane will prevent water from penetrating the roof and is easy to maintain. The following steps will teach you how to apply the membrane to the roof and how to care for it throughout the year.

Clean The Roof And Prepare The Membrane

Remove debris from the roof by hand or with a broom. Remove debris that is stuck on the roof's surface with soapy water and a scrub brush. Rinse the roof off and wait for it to dry. Measure the length and width of the roof. Use a pair of scissors to cut the rubber membrane so that it is slightly larger than the measurements of the roof.

If the membrane is a little bit larger than the roof, you won't have to worry about any parts of the roof being exposed if the membrane isn't lined up perfectly. After you have installed the membrane, excess material can be trimmed off with a utility knife. 

Apply The Membrane

Line up the membrane with the roof and fold one side of it back. Pour roofing adhesive in a paint tray. Apply the adhesive directly to the roof with a paint roller that has a thick nap. Move the roller along the roof's surface in straight lines, making sure that the adhesive is evenly applied. Press the folded back half of the membrane onto the roof.

Push a squeegee firmly across the membrane's surface to remove wrinkles and to assist with flattening out the material. Apply adhesive to the other side of the roof and apply the membrane to the roof. Wait for the adhesive to dry. This may take a few hours. 

Secure And Trim The Edges

Use a nail gun or hammer to insert a couple roofing nails in each corner of the roof. The nails will help hold the membrane in place. Trim excess pieces of material around the edges of the roof with a utility knife. The membrane will last for several years as long as you take care of it on a regular basis. Rinse it off with a water hose whenever it appears dirty. Remove stains with a natural bristle scrub brush and detergent. Contact a company like A-1 Roofing & Siding for more information.
