If a roof is installed properly and well-maintained, it can last for 20-25 years. However, if your roof isn't correctly ventilated or has only one layer of shingles, its lifespan will be affected. Typically, we recommend replacing a roof when it's 20+ years old. E & D Roofing, Inc. completes top-notch roof replacements in Waynesville & Springboro, OH and the surrounding areas.
