Most metal roofs come with a 30 to 50 year warranty that should cover any needed repairs. You may also be able to call the manufacturer of the roofing materials to ask for recommendations of contractors in your area. Metal roofing has the benefit of being nearly maintenance free and rarely require repair. However, certain instances may cause the puncture of metal roofing or other threats to water tightness, especially with older tin roofs. If you prefer to repair the roof yourself there are a couple of simple methods for applying a metal patch.

Your first consideration when working on a metal roof is to walk carefully so you don't dent or scratch the surface. If your roof has a very steep slope you may be better off hiring a professional than risking injury to yourself or the roof. If you feel comfortable tackling the project you will need the following tools: work gloves, safety goggles, an extension ladder, metal cutters, a wire brush, a piece of metal made from the same material as your roof, heavy stones or weights, a soldering gun, solder, and flux. You will want to cut the metal patch to a square or rectangle of the appropriate size (at least two inches larger than the area to be repaired) and then clip the corners off allowing you to fold under the edges ½ inch on each of the four sides. Next you should use the wire brush to clean the area needing repair. Now you are ready to apply the flux agent (which removes any oxidation) to ensure proper bonding. After applying the flux to both surfaces, weight down the patch with heavy stones or another heavy object over the area in need of repair. The next step is to use the soldering gun to heat the edges of the patch and apply solder around the circumference of the patch.

To create a patch without the use of a soldering gun you can use roofing mesh, a knife, and roofing cement. This method will work better on aluminum roofs but will not last as long as the soldered method. Like the method above you will need an extension ladder, safety goggles, work gloves, a wire brush, and metal cutters in addition to roofing mesh, a flat knife, and roofing cement. Your first step will be to cut two matching pieces of the roofing mesh using the metal cutters. You should be sure to wear work gloves and goggles while cutting any type of metal. Once again you'll use the wire brush to clean the area and then apply rubber cement to the entire area with the knife. You'll place the first patch over the damaged area and then cover with more cement working it down into the mesh. You're then ready to place the second patch over the first applying another layer of cement and working it into the mesh. When the roofing cement dries you will have a patch that corrects any leaks in your metal roof.
