A roof is consistently exposed to the elements. If you don't take care of your roof, molds, mildew and debris can build up. It is important you have the correct tools to take care of your roof. First you will need a utility knife. Utility knives can be used to cut drywall, trim asphalt roof shingles, and slice through fiberglass insulation. Utility knives are relatively safe to use since they have a retractable razor blade. In addition to the utility knife, you'll also need a roofing hammer that will refasten shingles and other roof coverings. A roofing hammer has two different head styles: one has a curved claw and the other has a straight claw. Most Residential roofing repair Fenton recommend the straight claw hammer. To cut wood, shingles or roofing panels, a circular saw would be the best tool. This electrically-powered tool can cut roof panels and plywood sheathing into an array of different sizes. Roofing nail guns are very efficient tools for hammering nails in. Compressed air is used to force the nails from the loaded gun.
