GSM Roofing

On behalf of everyone at LancasterHistory, we are very grateful to GSM for the quality craftmanship your team has demonstrated on the restoration of President James Buchanan's back porch roof. Thank you and happy holidays!

Troy & his co-worker went above and beyond while working the past few weeks at our administrative building, Berwick Industrial Development Association (B.I.D.A.). These two gentlemen were not only courteous, professional and friendly, but they were willing to go that extra mile. We highly recommend them and hate to see them go!

GSM Roofing is very lucky to have Troy and his co-worker as part of their team!! 5 stars +

ALSO - after seeing several other reviews, we must note, the guys ALWAYS wore their masks while in and out of our building! Very respectful.
