Siena College Friary Roof Reconstruction Design
Loudonville, New York
Siena College drew upon Mosaic’s services for a reconstruction design plan for the batten seam metal portion of the building that houses the college’s Franciscan Friars.
The one-story brick masonry building, built in 1981, had an inverted-roofing membrane system. The center portion had previously been updated to an adhered EPDM system.
The outer portions of the roof portion had a zinc alloy batten seam roofing system that did not provide for venting and had discontinuous insulation at the perimeter roof edge. In the winter, icicles at the eaves grew to more than five feet long, blocking windows and curling back toward the building.
Mosaic plan provided appropriate venting under the roof panels, minimized icicle formation, recycled the existing zinc alloy roof materials and exceeed the current energy code standards – all without disrupting the occupants of the Friary during construction. Mosaic performed field verifications and studied record drawings, then identified the roof system problems, such as corrosion caused by adjacent dissimilar materials. The design team laid out a project schedule with probable costs and specifications for the complete tear-off of the existing deck, and installation of new vented composite-board insulation, a vapor barrier, barrier board and standing seam aluminum roof panels with a kynar finish.
