Traditional manufactured homes often are constructed with metal roofs for added strength and protection. Metal roofs are designed to seal out water, shed snow and withstand high winds. While metal roofs are durable and resistant, they occasionally become damaged due to harsh weather, deterioration and rust. Leaks on manufactured home roofs typically occur at the seams, flashing, J-rails and rumble buttons. Damaged and worn areas of metal roofs can develop holes. You should make repairs to your manufactured home's metal roof promptly to prevent permanently damaging your walls, woodwork, flooring and other interior components. Does this Spark an idea?
Instructions
1. Scrape the damaged area of the metal roof with a putty knife to remove all loose dirt, roof coating and caulk. Sweep the debris off the roof with a broom.
2. Adhere 1-inch-wide strips of butyl tape around the perimeter of the hole. Cut the tape to length with a utility knife. Form a square with the tape strips.
3. Place a galvanized metal patch over the butyl tape strips. Make sure the patch covers the hole by 3 inches on all sides. Cut the patch with tin snips if necessary to get the right size.
4. Drill holes every 2 inches along the perimeter of the metal patch and into the roof. Use a drill bit slightly smaller than your metal screws. Place the screws in the holes and screw them in with the drill outfitted with a driver bit.
5. Place a tube of roofing tar into a caulk gun. Cut off the end of the tube at an angle with your utility knife. Squeeze the gun's trigger to apply roofing tar around the edges of the metal patch. Release the trigger to stop the flow. Coat the screw heads with roofing tar. Allow the tar to dry according to the label directions.
6. Cover the entire patch with rubber roof coating, applied with a roller brush. Allow the roof coating to dry according to the manufacturer's directions.
7. Clean all of the seams, J-rails and flashing on the roof with the putty knife. Cover the seams, J-rails and flashing edges with a coat of urethane roof cement, using a stiff-bristle paintbrush. Allow the roof cement to dry according to the label instructions.
