Scope of Work • Roof Areas: The Upper Roof is Tar and Gravel built over 2” perlite insulation board over a metal deck, approximately 250 sq ft. The Lower Roof is single ply TPO over insulation board on a metal deck, approximately 7,700 sq ft. • Materials Required: Upper & Lower Roofs one layer of 1.5” Polyisocyanurate insulation board to be fastened over existing roofing for additional R-Value.
