Summary
Provide roof replacement at school. The project consists of a full tear off and replacement of low slope roof within the scope of work areas. The existing roof consists of areas of TPO single-ply roofing, which will be removed to the existing deck and replaced with a new fully adhered EPDM roofing system. Existing flashings, roof edge metal, coping and roof expansion joints will be replaced. The existing roof decks consist of areas of steel roof decking and one area of concrete deck at the connector to the north wing. Roof drains will be removed for the installation of new roof drains and new overflow roof drains. Some roof drain locations will be abandoned, and some will be moved, new storm piping will be required to connect back to the existing storm drain stack/line. A secondary roof overflow piping system, overflow scupper or gutter system will be installed to provide primary and secondary drainage. New steel roof decking will need to be added to patch holes for the removal of roof top equipment, roof drains, and at existing skylight locations. Through the wall secondary drainage overflow scuppers will be installed at all bifunctional roof drains. There is serviceable equipment within 10' of the roof edge and skylights so a portable roof safety railing system will need to be installed. Some of the abandoned existing roof top equipment will be removed. The new EPDM roofing system will require provisions for roof edge heights and the associated roof flashings. Masonry restoration will be required at the existing gym walls to provide new flashing and counter flashing.
