Durability
Risks
- 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 homeo…
Resources
- Most of the tools and materials you'll need can be found at any home center or hardware store, but you may need to seek some of these items from a roofing store that carries a range of roofing materials and repair products.
Use
- After cleaning the surface of the metal panel, use a wire brush to scuff the surface where the repair will be made. Scuffing the surface will help the sealant bond to the metal. Use the wire brush only in the area to be patched; wire brushing beyond that may remove the protective coating from the metal panel surface, causing later deterioration. Ap...
Prevention
- Cut the chosen sheet metal to a size that matches the area to be patched. The sheet metal patch should overlap onto the metal panel at least 2 inches past the edges of the damaged area. After the sheet metal patch has been cut and fit to size, round the corners of the patch with a file or emery cloth to prevent any sharp corners from becoming a catching spot for snow or ice.
Preparation
- Once the patch has been measured, place it over the hole being repaired. Take a pencil and outline the patch onto the roofing. Remove the patch and examine the outline to make sure the patch will overlap by at least 2 inches in all directions past the edges of the damaged area.
Treatment
- Press the patch into place over the damaged area. The sealant should squeeze out from the leading 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. If the hole or damage to the roof is …
Safety
- Safety is a major concern when completing any roof repair project. A hole in a roof system may indicate 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. If there are concerns about completing your roof repair safely, c…
