A Chicago Housing Authority Building is in need of removal and replacement of clay tile roofing. The removal will go all the way to the structural slab, along with existing concrete topping slab and existing flashing at all existing penetrations. They will be replaced with new flashing at eaves, and roof edges, and new masonry flashing will be provided at masonry walls and chimneys. 2-layers asphalt-impregnated roofing felt and self-adhering sheet underlayment ice and water shield will be installed. All gutters will be reconnected to existing downspouts.
