A roof is consistently battling the elements. If your roof isn't taken care of, mold and mildew can build up. It is important you have the proper tools to take care of your roof. First you will need a utility knife. They can be used to cut drywall, trim asphalt roof shingles, and slice through fiberglass insulation. They are pretty safe to use since the razor-sharp blade can be retracted. Besides a utility knife make sure you invest in a roofing hammer with a straight claw. Invest in a circular saw to cut singles or panels. 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 push the nails from the loaded gun strip unto the sheathing or shingles.replacement roofing services Leesburg VA
