Asphalt roofs can last for over three decades with proper maintenance, but eventually, these roofs all begin to show signs of serious aging. Timing your roof replacement based on the signs of wear and tear allows you to get as much life as possible out of the current roof without risking damage to the rest of the structure.
If you notice distinctive waviness or unevenness among the asphalt shingles when looking at your home’s roof, schedule a professional inspection. This kind of distortion of the shingles indicates the roofing materials are near the end of their lifespan.
New roofs can develop a wavy appearance due to wrinkles in the underlayment or a lack of adhesion between the individual tabs. If your roof has looked smooth for years and has only developed an uneven appearance with age, the change is likely due to damage instead.
