A roof is constantly exposed to the elements. If your roof isn't taken care of, mold and mildew can build up. It is important you have the right 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 will 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 roof repair specialist crownsville, md 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 various different sizes. To hammer nails in, abandon the manual hammer and opt for a nail gun. Compressed air is used to force the nails from the loaded gun.
