Older roofing shingles and wood shakes have a life span of 15 to 30 years. Factors that affect the lifespan are shingle quality, location and tree coverage, and how well the roof was installed. Some warning signs of roof problems are: curling or loose shingles, water leaks on your ceiling, wind damage, and broken shingles. Finyl Vinyl carries and installs a wide variety of residential roofing shingles for any budget and taste.
