• polyisocyanurate board insulation
• corrugated metal roof deck
The building photovoltaic system is located on three areas of the roof. Above the staff wing of the building the panels are mounted on racks that are supported by spaced wood frame fin walls standing up from the roof below, allowing the tapered roof system below to pitch to drains. Above the main reading room, the panels are mounted to TPO-wrapped wood sleepers anchored to the roof deck below.
At the steep-sloped section of A and B, install a new double locked standing seam coated metal roof system that is similar to existing Roof Area G. New standing seam roof will include high temperature underlayment, eave and rake flashing. and transition to TPO roof system. Existing PV system will be secured to stand seams utilizing PV clamps.
PROPOSED SCHEDULE
District wishes to complete remedial roof work in the Spring of 2024. However, if a different timeline is needed due to other commitments, please submit a proposal detailing a timeline that would work.
