When your roof starts showing signs of damage, it may be hard to determine whether a simple roof repair or a replacement is better. If you are looking to replace a damaged roof, you may want to get a quote from at least three roofing contractors before you make your final decision. First, you need to find a good contractor. You can start by asking for a list of potential contractors to give you a starting point for choosing one. Check out their credentials and ask for references from friends and family.
