6 mil uv stablized it runs about $3 a foot about 25ft wide so i need about 3 runs out it plus the ends. i'm told it lasts 4 years no problem and if i keep it tight and clean it will go two or three more. everything else was to much money for the ease of installing plastic i'll do the extra work every so many years. plus it may get better with time. I dont think wiond is the issue with the plastic i think its more on how its installed. i've seen on you tube large snow loads setting on roofs as well as crushed so common sense and a shovle or heat goes a long ways.
