NFL Building Sloped Roof Replacement

Summary of Scope of Work The NFL Building has sloped asphalt shingle roofs and flat roofs, this project includes the replacement of the sloped main roofs and small canopy type sloped roofs only, no work is to be done on the flat roofs. The existing roof has asphalt shingles over asbestos shingles. Work under this contract includes having a licensed asbestos and lead abatement contractor strip the shingles both asphalt and asbestos and remove the deteriorated molding, fascia and soffit which are coated with peeling lead based paint as well as the existing gutters and leaders. The contractor that is awarded this contract will be required to coordinate work with the abatement contractor that will do the removals and the crew that will install new soffits, fascia, roofing, gutters downspouts, vents etc. The abatement contractor is to work nights and remove as much roofing as can be replaced in one day. The installation crew will work days and replace the woodwork and roofing on the section of roof that was stripped the previous evening and all materials removed to be disposed off to a legally approved site. This contract includes new gutters, downspouts, soffits and fascias. Lead and asbestos abatement The abatement contractor must be licensed to perform lead and asbestos abatement projects in Suffolk County and must comply with all pertinent federal, state and local regulatory requirements for the removal of asbestos containing material and lead. The college will hire an independent environmental testing firm to monitor the abatement activities and perform the requisite testing. Products to be used This specification is based on GAF products, equivalent products by other manufacturers may be used if the substitution is approved by the college.

Shingles – Timberline HD or approved equal

Starter strip – Weather Blocker Eve/Rake starter strip or approved equal

Leak Barrier – Weather Watch or approved equal to be used at all valleys, ridges, and eaves.

Shingle Underlayment – Deck Armor Premium breathable deck protection or approved equal

Flashing .032 inch aluminum painted white

Fascia and blocking – pressure treated #2 or better.

Soffits – perforated vinyl or aluminum soffit material.

Drip edge - .032 inch minimum, aluminum painted white. Installation specification As per GAF spec sheet included with this document. Air intakes and vents The three air intake louvers that penetrate the roof (shown in the photo below) are to be replaced with aluminum goose neck screened air intakes that are raised so that they are at least 18 inches above the roof so that they are above the snow line.

Exterior louver and ductwork to be painted aluminum, submit shop drawing for approval. Roof Deck The existing roof deck is constructed of tongue and groove lumber and appears to be in good condition, however bidders are required to provide a unit cost (per square foot) to replace decking that is found to be unsound. Dimensions The drawing provided below is provided as a guide actual dimensions should be verified by bidders prior to submitting bids. Fascias, Gutters and Soffits The existing wood fascias and soffits are decayed and covered with peeling lead based paint. They will be removed by the abatement contractor and replaced by the installation contractor as part of this bid. When originally constructed the building did not have gutters, instead it has decorative molding applied to the fascia (as shown in the attached drawings). The molding prevented the proper installation of the gutters. The contractor is to replace the fascia removed by the abatement contractor and add continuous pressure treated wood blocking (as shown in the attached drawings) to which the new gutters will be installed. The replacement soffits are to be perforated vinyl (white).
