How To Repair A Hole In The Metal Roof On A Mobile Home

Holes in manufactured or mobile homes can be created by falling tree limbs or large hail. Once the hole begins, it can, over time, become larger. Repair should be done as soon as possible. Inspect the roof thoroughly before climbing on top of it, as the underlying wood frame may also contain damage. Even if the roof appears to be structurally sound, use a piece of ½-inch plywood as a steeping surface when walking on the roof.

  • Place the ladder in a secure location to gain access to the roof. Set the plywood pieces on the roof. Use the plywood as your steeping structures and work your way to the hole on the metal roof.

  • Scrape away any loose paint or rust around the hole with the metal paint scraper. Use the wire brush and work down to bare metal around the hole. Remove the paint from around the hole to permit installing the butyl tape in a square shape around the hole.

  • Secure the self-adhesive butyl tape around the hole. Cut the galvanized steel patch material with the tin snips to match the area of the butyl tape. You will want the metal patch to fully cover the butyl tape.

  • Press the metal patch firmly into place with your hand. Secure the metal to the roof with the self-tapping screws and the powered screwdriver. Pattern the screws around the perimeter of the metal patch, approximately 2 inches on center.

  • Paint over the patch and the surrounding roof area with the roofing paint. Extend the painting area to approximately 1 foot around the new roof patch.

    Fix Small Holes

    Metal roofs are thinner than other roofing materials and prone to getting bent or even punctured when you walk or stand on them. Not only that, but foot traffic can cause low spots and water ponding on near eave and at panel endlaps which will encourage leakage. Also, each one of those dings and dents, even minor ones add up and alter the beauty of the roof.

    So, if someone must walk on the roof make sure they know to walk on the flat part of the panels for exposed fastener and standing seam systems, using the joists or purlins for support. The fancier architectural styles of metal roofing will need to be evaluated on a case-by-case basis. Now for a safety warming. Metal roofs, every one of them, are dangerous. The metal is slick under dry conditions. When wet, frosted, icy, or snow-covered, trying to walk them is likely to be followed by a trip to the emergency room. The general rule of thumb is to stay off it entirely, if possible.

    Remember, metal roof repair isn’t the only solution to improving your roof’s performance and durability. While a simple repair will answer many problems in the middle of a storm, it isn’t a long-term solution that only professional roofers in Clinton Township MI can provide.

    When a metal roof system is installed properly, its life expectancy is second to none. According to the National Association of Home Builders, asphalt shingles last, on average, about 20 years, composite shingles about 25 years, and wood shakes or shingles about 30 years. Aluminum or steel roofs, on the other hand, can easily last 50 years or more, and zinc roofs have been known to last 80 years or more.

    But no building material, especially one that faces the constant weather battering of a roof, lives forever. Like all roofing systems, a metal roof requires regular maintenance and repair. Any roofing repair can be a hit-or-miss proposition. Done properly, repairs can last as long as the roof system itself. Done improperly, those same repairs can quickly break and fail, leaving the homeowner or building owner with a recurrent or constant leak. A recurring leak can be aggravating, but more serious is the interior damage and mold growth it can cause. It is always best to fix a roofing problem quickly and correctly.

    If this is happening to your building, a great place to start is by contacting a roofing contractor who can evaluate the current situation.

    How To Repair A Flat Roof

    Flat roofs are frequent on older structures and arid climates since they are typically level. These roofs are safe, but you should regularly inspect the cracks and problems that cause degradation.

    Most flat roofs are road surfaces, rubber, polyvinyl chloride, or synthetic material.

    Asphalt can be resealed with bitumen or caulked, so although elastic and synthesised membranes are frequently simple to fix with adhesive patches, only if your canopy is in very poor shape will being diligent with repair work prevent severe damage extend the life of your roof.

    Scour The Metal Surface

    Once youve cleaned the metal panel surface, scour the repair point using a wire brush. The purpose of scuffing the metal panel is to ensure that the sealant bonds well to it. However, you should only scour the surface to be patched. Otherwise, the wire brush may peel off the protective coating on the other parts of the metal roof surface.

    Install The Repair Patch

    Apply a color-matched urethane sealant to the surface of the metal panel being repaired, staying just inside the marked pencil line. Apply the sealant liberally in the area, so that there are no gaps or voids at the leading edge of the patch.

    Press the patch into place over the damaged area. The sealant should squeeze out from the edge of the patch along all sides. If there are areas where the sealant is not oozing, these are areas where moisture may later penetrate under the patch, causing a deterioration of the patch. Apply a little more sealant here to eliminate any gaps.

    Place The Patch Over The Repair Area

    Once youve cleaned the metal panel, apply urethane sealant on the surface to be repaired, ensuring there are no gaps. Dont spread the adhesive to the unaffected areas, as that may interfere with your roofs integrity. Next, place the sheet metal patch over the damaged surface. Youll notice the sealant squeezing out from the patchs edges.

    Prepare The Area To Patch

    Inspect the damage to ensure nothing is extruding up that would interfere with the patch laying flat on the repair area.

    If anything is obstructing the patch, cut or pound it flat if possible. If a flat surface is unobtainable, then replace the panel or make the patch larger.

    Once the surface is deemed repairable, clean the area thoroughly with the cleaner. Make sure the surface is free from residue.

    How Metal Roofs Get Damaged

    Metal roofs can get damaged in the same ways that other roofs can, even if they seem to be more resistant to damage.

    • Poor installation such as poor caulking, sealants, and flashing can lead to roofing damage.
    • Weather and age can damage the roof. Seams separate, the roof rusts, coatings come off, and sealants fail. Ice dams move water under the roof, and branches and wind loosen or damage the roof.
