I'm a Metal Roofing Fabricator located in central PA. I have been re-roofing existing mobile home roofs for about 11yrs. I have a system, I use, that is less then 1 lb. per sq. ft. It is ventilated and also strenghthens the existing roof structure. There are 13 beautiful colors to choose from. Putting this system on will assure the end to any and all roofing issues.(814)224-4268 or email: [email protected] so if you would like to have more info. please contact me. thanks.
