We recommend removing all loose items from walls and shelves that may suffer damage if dislodged, especially if your job involves a roof removal. A good example would be your Great-Grandmothers china displayed on a plate shelf in your kitchen! The ongoing work may cause enough vibration to shake these items down. While we are careful, keep in mind we are moving items around on your roof that can weigh in excess of 100 lbs, so some shaking and vibration will occur. Make sure to clear your driveway and items directly surrounding your home. At any time if you are unsure of just what needs to be moved, please feel free to contact us.
