Metal roof is no doubt stronger and safer than any other roof. The top of your home is protected with metal roofing. The rooftop if provided with regular maintenance will remain intact for a span from 40 to 50 years. Regular maintenance, timely repairing and handling roofing problems will ensure you maximum longevity of your home rooftop. Roof repairing systems vary depending on metal roofing types. Use only compatible roofing materials to repair a particular metal roof. 
Many roof repairing materials of caustic nature cause corrosion. Make sure to have a read of the manufacture’s care instructions on every roof repair product before using it. Roof maintenance and repairing steps vary. The following are general and common repairs that almost every metal roof requires –
• Pulling and re-nailing loose nails
• Looking for holes, leaks, fungal buildups and rust patches
• Sealing leaks and holes with urethane roof cement
• Re-calking the edges of the roof
The Process to Patch Holes in a Metal Roof -
• It is better to use repairing metals of the same type as that of the roof. Or else, the metal used in repairing the roof can cause corrosion. At first, clean the part of the roof to be repaired using an all-purpose cleaner and brush it and then, leave it to dry.
• The patch must be larger than the damaged part by two inches. Remove the corners as well using tin snips. Get the edges folded under half inch. Sand the folded area until it looks shiny. Put flux on the part where will be the patch. Put a brick on the patch to weight it down.
• Hold solder along the seam. Heat it with soldering iron so as to melt it and make it go under the patch. Repeat the process around the patch, leaving no open space.
• Cut two or three more patches. The patches should not be smaller than the hole. Rather, they must be larger. With cement, coat the damaged roof area. Apply the other coat pressing one patch.
