Desired Work shall consist of a total roof replacement with a 60 mils TPO, which means completely removing the existing roof system and replacing it entirely with a new TPO (thermoplastic Polyolefin) membrane, essentially tearing off the old roof and installing a new one made entirely from TPO material. 1. Complete tear-off involves removing all existing roof layers, including the underlayment and any existing membrane, before installing the new TPO. 2. Heat reflective: 3. TPO membranes shall be white, which helps reflect heat and can keep the building cooler. 4. Installation process: The new TPO membrane shall be mechanically heat-welded to create a seamless roof system. (hand weld 1.5 overlaps, spec weld, no stitching appearance with no bleeding out) • Deck Preparation: • Thorough cleaning of the roof deck • Inspection and repair of any damaged roof deck components, such as rotted wood or cracked concrete • Installation of new roof deck sheathing if required • Insulation Installation: • Installation of the specified insulation material (typically polyisocyanurate (polyiso) or expanded polystyrene (EPS)) on the roof deck • Proper attachment of insulation boards to the deck using mechanical fasteners • All roof systems in this scope of Work shall be designed and installed to withstand a minimum of a 100 MPH wind load.
