Description
The King County Housing Authority will accept Bids from Qualified General Contractors to furnish labor, materials and necessary equipment to complete removal and replacement of eleven roofs as listed in the bid documents.
Scope of Work
Work will include the removal and disposal of the existing asphalt roofing system, metal ridge vent, wood framed chimney, metal soffits, gutters, and downspouts. The existing bath and range venting that is piped through the soffit overhangs will be relocated and hard-piped directly through the roof sheathing.

The existing furnace piping inside the existing chimney will need to be extended and piped through with a new B-Vent. The roof overhang and cantilevered beams at the carport roof will each be cut back to an 18”overhang in order to remove the existing rot from the beams. Contractor will repair areas of rot as needed. New 2x6 PT sub fascia and barge board will be installed and blocked accordingly. All existing barge and fascia boards will be removed and replaced with 5/4 x8” Hardi. The new roof assembly will be mechanically-fastened, TP membrane and cover board over the existing sheathing. Contractor to budget five sheets of ½” plywood per roof for any unforeseen repairs.
