I live at 8425 feet elevation in Boulder County Colorado. I have had GAF Woodruf Shingles on my home for 11 years. They are fine! My wife and I want to sell our home and build another. Our Realtor told us if we want to sell our home we will have to replace a perfectly good roof. I had never heard of this problem other people are having. She told us that there was a class action lawsuit against Masonite Woodruf shingles. My shingles are GAF Woodruf Shingles. Does anyone know if thes are included in the lawsuit. Anything sent to my E-mail address will be appreciated.
