Although masonry and metal roofs generally last longer than other types of roofs, they do still sometimes need repairs. Leaks are one type of problem that can develop on masonry and metal roofs, and damage to tiles and panels is another. Because slate, concrete tile and all types of metal roofing require more skill and tools to work on than asphalt roofing does, homeowners should turn to a professional Fort Worth roofing company for repairs.
Simply using plastic roofing cement works fine to patch up small cracks and holes in slate and other masonry roofing. In such cases, roofers use a wire brush to clean out damaged areas before applying the roofing cement. However, if a crack in a masonry tile has spread to the overlap of the course of shingles below it, using plastic cement is not enough, and the best procedure is to remove and replace the entire tile.
It's simple to remove and replace a masonry tile that has been laid down directly over the roof sheathing. Roofers usually use a prybar or shingle ripper to gently remove the tile and then spread some roofing cement to put down a new tile.

The process is trickier, however, if the damaged tile is attached to a batten. In this case, the surrounding tiles must be removed first using a prybar. Then, the tile attached to the batten is broken up with a hammer.
As with masonry roofing, small holes in metal roofing can be simply patched with plastic roofing cement. However, any hole with a diameter more than a half an inch must be patched with the same type of metal as the rest of the shingle. Using a different type of metal could cause corrosion where the two materials overlap.
When patching metal shingles, the hole is first rubbed down thoroughly with a wire brush or rough sandpaper. The patch itself should be about two inches larger than the hole it is covering on all sides and is attached using plastic roofing cement. The procedure is to apply cement, hold down the patch for a few minutes and then cover the entire area with a final layer of cement.
When a metal panel is dented, usually the entire panel has to be replaced. How this is done depends on the interlocking system used by the manufacturer of the panel. With metal panels, it's usually best to return to the same roofers who did the installation when a replacement needs to be done.
