Roofs are continuously exposed to the weather. All roofs require constant maintenance that can be taken care of by the owner or a roofing repair service. Here are some supplies homeowners can use to make sure their roofs are maintained correctly. A utility knife can be used to trim shingles or 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 regular maintenance tasks.roofing companies in Iowa
