Roofing is a major cost, so it's important to be able to evaluate the condition of your roof. When you're looking at your roof, it's important to remember that it needs to be cleaned up from time to time. AZ Shingle Pros, LLC full-service roofing companies in Phoenix are committed to serving you and your home. If it's dirty and in need of cleaning, then you should consider hiring professionals for this task. The first step in evaluating your roof is making sure that the shingles are still on the roof. If you have had them replaced and they have been removed, then there may be water damage underneath them. The best way to determine whether or not there is water damage under your shingles is to determine if they are sticking up at all in some places or if they are even overhanging at all.
