a. A four-ply fiber glass hot applied built-up roofing system.

b. A single-ply ethylene propylene diene monomer (EPDM) which can be loose laid, adhered or mechanically attached.

c. A modified bitumen system which can be heat welded, hot bitumen, or adhered; and with a surfacing which shall completely cover the membrane.

d. A standing seam metal roof system shall be from a single manufacturer with a minimum of 24 gauge galvalume sheets attached to slip clips for expansion and all seams double locked or pittsburged rolled.

Roofs shall be specified, as well as guaranteed, as a system and shall include vapor retarders, insulation, bitumen, felts, membranes, flashings, metals, decks, and/or anyother items where required by the proposed roof design. All manufacturer's materialsused in the roofing system shall be specified to meet the latest available ASTM standards for individual components of the roofing system. Certification from the roofing manufacturer shall be furnished at the pre-roofing conference as well as when the material is delivered to job site. 2. GUARANTEE

a. The four-ply built-up roof system shall have a 20-year unlimited manufacturer's guarantee for water tightness covering material and workmanship on the entire system.

b. The single-ply EPDM system shall have a 15-year manufacturer's guarantee for water tightness covering material and workmanship on the entire system, limited to the installation cost of the roof system.

c. The modified bitumen roof system shall have a 20-year manufacturer's guarantee for water tightness covering material and workmanship on the entire system, limited to the installation cost of the roof system.

d. The standing seam metal roof shall have a 20-year, 6-month unlimited manufacturer's guarantee for water tightness covering material and workmanship on the entire system.

e. In addition to the above guarantee, the general contractor and/or the roofing contractor shall provide a written guarantee agreeing to keep the roof free of leaks for a period of two (2) years starting at the time of acceptance of the project by owner.

3. ROOF SLOPES a. All roof construction on new buildings shall have a built-in minimum slope to drains or eaves of 1/4 inch per foot. b. All replacement roofs shall have a minimum slope of ¼ inch per foot where feasible; but in no case shall the slope be less than 1/8 inch per foot. Justification must be requested and approved by the State Department of Education for roofs less than 1/4 inch per foot.

4. SUBSTRATE The type roof system selected shall be compatible with the substrate and shall be approved by the roofing material manufacturer. All decking material used for roofing shall be UL fire rated.

5. INSULATION a. Roof insulation shall be of the type approved by the roofing manufacturer for the roof assembly in which it is to be used. The required minimum "R" value shall be specified. b. On replacement roof projects that do not have a sloping deck, tapered insulation shall be used where feasible.

6. ROOF TOP EQUIPMENT a. Roof top equipment on new construction is not desirable, and the building should be designed to eliminate the use of this equipment. However, where equipment must be installed on a roof, it shall be approved by the State Department of Education and shall be installed in accordance with NRCA (National Roofing Contractors Association) design details which shall be such that roofing can be easily accomplished without the removal of the equipment. b. Where equipment on the roof must be periodically serviced, easy access and traffic pads shall be provided.
