Roofs are constantly exposed to the weather. All roofs require consistent maintenance that can be taken care of by the owner or a professional roofer. Here are a few supplies homeowners can use to make sure their roofs are maintained properly. A utility knife can be used to trim shingles and also to expose nail heads. Invest in a circular saw, a roofing hammer, roofing nails, a roofing nail gun, and a pry bar. These tools will help you complete routine maintenance on your roof.home roofing replacement estimate Hillsboro OR
