Great to know the material holds up so well. After seeing a sample of it and seeing how strong it was I suspected it would last for many years. Mine is stapled to the sheeting directly under the metal roof so it's worst abuse probably comes from the heat. The metal is warrantied for either 30 or 40 years and if it lasts 40 years someone else will likely be putting the next roof on since I'd be 91 years old and likely be dead. Do you have any idea what the percentage savings it made in your energy costs were? We've already had days in the mid 90's this year, but the house stayed comfortable until late in the afternoon even without using the a/c.
