Install new shingles and install an approved underlayment for the entire roof. Also remove the existing flashing, drip edge and roof vent boots and replace with new and in-kind. Completely remove one 10-inch stove pipe, and one 4-inch Vent pipe and two 2-inch vent pipes on the Warehouse that are obsolete and then patch and repair the holes in the decking. All measurements will need to be field verified by the contractor.

Exterior wood elements that are replaced will need to be painted to match existing. Park will provide paint for repainting. Coordinate with COR for paint and paint color. Contractor shall attempt to conduct work without disassembling the gutters and/or downspouts. If Contractor must detach the gutters and/or downspouts to conduct work, Contractor shall reattach the gutters and/or downspouts.

Work will include the replacement of approximately 100 linear feet of deteriorated soffit, fascia/crown molding on the southside of the Medical Directors Residence. The northside of the MDR should not need any work but should be inspected for verification. Replace approximately 150 square feet of deteriorated wood decking. Replace all deteriorated flashing, drip edge, vent boots, chimney flashing, and rake flashing with new, in-kind materials. The rake on the eastside and the westside should be inspected and replace any deteriorated wood as required.
