1. Provide tie-offs at end of each day's work to cover exposed roofing sheets and insulation with a course of coated felt set in roofing cement or hot roofing asphalt, with joints and edges sealed.
2. Complete terminations and base flashings, and provide temporary seals to prevent water from entering completed sections of roofing system.
3. Remove and discard temporary seals before beginning work on adjoining roofing.
3.5 INSTALLATION OF BASE SHEET
A. Before installing, unroll base sheet, cut into workable lengths, and allow to lie flat for a time period recommended by manufacturer for the ambient temperature.
B. Loosely lay one course of sheathing paper, lapping edges and ends a minimum of 2 inches (51
mm) and 6 inches (150 mm), respectively.
C. Installation of SBS-Modified Self-Adhered Fiberglass-Mat Base Sheet:
