Work consists of the removal and replacement of existing low-slope roofing systems, including verification and supplemental topside sealing of concrete roof deck joints. Area A (7,814 SF) (Base Bid): Remove the existing adhered EPDM roofing and hot-mopped, multi-layer tapered polyiso insulation. Install a new roofing assembly consisting of a vapor barrier, tapered polyiso insulation, coverboard, and ballasted EPDM roofing system. * Area B (2,786 SF) (Alternate No. 1): Remove the existing adhered EPDM roofing and one layer of mechanically fastened polyiso insulation. Install a new roofing assembly consisting of a vapor barrier, two layers of polyiso insulation installed using low-rise foam adhesive, coverboard, and adhered EPDM roofing system. * Area C (2,437 SF) (Alternate No. 2): Remove the existing adhered EPDM roofing and one layer of hot-mopped polyiso insulation. Install a new roofing assembly consisting of a vapor barrier, two layers of polyiso insulation installed using low-rise foam adhesive, coverboard, and adhered EPDM roofing system. * Area D (4,470 SF) (Base Bid): Remove the existing ballasted EPDM roofing and EPS insulation. Install a new roofing assembly consisting of a vapor barrier, two layers of polyiso insulation, coverboard, and ballasted EPDM roofing system.
