Repairing a Hole in a Metal Roof System. By Christophor Jurin. When properly installed, a metal roof system's life expectancy is second to none. But like all roof systems, they require regular maintenance and repair. Roofing repairs can be a very puzzling process.
Done properly repairs can outlive the roof system that they have been applied to. Done improperly, those same repairs can continue to break and fail leaving the homeowner or building owner with a continual leak condition. A recurring leak condition can be a source of aggravation but also can lead to interior building damage and potential mold growth. It is always best to fix the problem right the first time and be assured that your solution will deliver your goal of a watertight roof system for a long period time. Repairs to the surface of a metal roof system can prove to be one of the more difficult repairs to complete.
Metal roofing repairs are prone to premature failure due to the difference in the expansion and contraction of the metal roofing panels in comparison to the applied repair. This difference in expansion and contraction between the two products places stress on the repair and leads to cracking, splitting and ultimately failure of the patch. The following is a recommended process for completing a repair for a hole in a metal roof system. Tools needed: Metal snips. Cordless drill. Wire brush. Caulk gun. Paint brush.
Pencil. Materials needed: Sheet metal . The hole may be from deterioration and rust or it may be from something falling onto the roof surface such as a large branch.
No matter what the cause of the hole, the area of the roof where the hole has occurred is most likely dirty and requires cleaning. Clean the surface of the metal panel using Simple Green or other cleaner. Clean the surface of the roof panels until any dirt, film or algae growth is completely removed.
Any residue will compromise the integrity of the roof repair. After cleaning the surface of the metal panel, use the wire brush to scuff the surface of the metal panel where the repair will be installed.
The wire brush scuffs the surface to allow the sealant being applied to attach to the surface and not to simply sit on the surface of the metal panel. The wire brush is to be used only in the area where the patch will be installed. Wire brushing beyond that may remove the protective coating from the metal panel surface causing deterioration of the panels. Step Two - - Cut Repair Area and Patch.
Cut the sheet metal to a size that matches the area to be patched. The sheet metal patch should bear on metal panel a minimum two inches past the leading edge of the damaged area. After the sheet metal patch has been cut and fit to size, round the corners of the patch to prevent any sharp corners from becoming a catch for snow or ice. Once the patch has been measured place it over the hole being repaired. Take your pencil and outline the patch. Remove the patch and ensure that there is a minimum of two inches in all directions past the leading edges of the hole in the roof system. Step Three - - Install Repair Patch.
Apply the sealant to the surface of the metal panel being repaired. The sealant should be applied so that it is just inside of 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.
Take the patch and press it into place. The sealant should bleed from the leading edge of the patch along all sides. If there are areas where the sealant is not extending from the edge moisture these are areas where moisture can penetrate under the patch causing a deterioration of the patch. Step Four - - Secure Patch.
Once the patch has been pressed in place, attach the patch to the surface of the metal roof panel using the pan head sheet metal screws. Apply the screws at a rate of three to four inches on center around the perimeter of the patch. The screws should be applied within one inch of the leading edge of the patch so that they apply uniform pressure to the leading edge of the patch and the sealant beneath the patch. As necessary after the patch has been attached, retool the sealant that is bleeding from the edge of the patch. This will ensure that the sealant properly seals the leading edge of the patch and prevents moisture from penetrating the leading edge. Step Five - - Paint Patch to Match Roof.
If desired, the surface of the patch can be painted to match the color of the metal roof panels. In order to complete this, lightly wire brush the surface of the metal patch and the metal panel just past the leading edge of the patch. Apply the paint to the surface of the patch and onto the surface of the underlying panel. Be aware that it may be necessary to wait for the sealant used under the patch to cure before applying paint to the surface of the sealant.
In addition, confirm that the paint selected is compatible with the sealant that was selected. Closing. Safety is a major concern with completing any roof repair project. A hole in a roof system may be an indicator that there are other concerns about the overall structure including decking deterioration.
Be sure to conduct a proper under deck safety review and roof analysis before attempting to complete this or any roof repair.
