Attach A Rubber Roofing Membrane To A Tool Shed's Metal Roof

If your tool shed's metal roof often becomes rusted after being exposed to wet conditions and you have grown tired of repeatedly removing the corrosion with sandpaper or other abrasive scrubbing tools, attach a rubber roof membrane to the existing roof. A rubber roof will provide a protective barrier that will prevent moisture from penetrating. Rubber roofing is also attractive and easy to clean.

Clean The Roof And Remove Thick Sections Of Rust

Purchase a rubber roofing membrane that is the same size as the tool shed's roof. Set up a ladder next to the tool shed. Clean the metal roof off with soapy water and a long-handled scrub brush. If there are any thick sections of rust on the roof's surface, eliminate them by moving a hand sander that has a piece of low-grit sandpaper attached to it or a scouring pad firmly back and forth over each one.

The rubber roofing membrane will lay flat and will adhere the proper way once the rooftop has a smooth surface. Rinse the metal roof with a water hose and wait for its surface to dry.

Attach The Rubber Roofing Membrane

Line up the rubber roofing membrane on top of the metal roof. Fold back one side of the membrane so that the metal roof is exposed. Use a paint roller to apply a thin, even coat of roofing adhesive to the metal in straight lines. Press the side of the membrane that was folded back firmly against the adhesive-covered roof.

Fold back the other side of the membrane and apply roofing adhesive to the metal in the same manner. Press the rest of the rubber roofing membrane against the roof's surface. Move a squeegee firmly across the roofing membrane to eliminates wrinkles.

Secure The Corners Of The Membrane And Maintain The Roof Covering

Use a hammer or nail gun to drive roofing nails into the corners of the membrane. Maintain the rubber membrane by removing debris from it and rinsing its surface off with a water hose. If visible staining appears on the rubber membrane's surface, eliminate it with soapy water and a scrub brush. Rinse the roof covering off afterwards. These basic steps will prevent damage to the membrane and will maintain its appearance.
