From a field inspection of the property,the existing roof support structures were observed as follows: The roof structure of(Roof A)consists of composition shingle on roof plywood that is supported by fink trusses that are spaced at @ 24"o.c..The trusses have a max projected horizontal span of approximately 26'-0" between exterior load bearing walls, and a slope of 40 degrees.The top chords are 2x4 sections,the bottom chords are 2x4 sections and the web members are 2x4 sections.The truss members are connected by steel gusset plates.The max unsupported projected horizontal top chord span is approximately 7'-0". The existing roof framing system of(Roof A)is judged to be adequate to withstand the loading imposed by the installation of the solar panels. No reinforcement is necessary. The spacing of the solar standoffs should be kept at 48"o.c.with a staggered pattern to ensure proper distribution of loads. I further certify that all applicable loads required by the codes and design criteria listed below were applied to the Unirac Solarmount solar rail system and analyzed. Furthermore,the installation crews have been thoroughly trained to install the solar panels based on the specific roof installation instructions developed by Unirac Solarmount for the racking system and Ecofasten for the roof connections. Finally, I accept the certifications indicated by the solar panel manufacturer for the ability of the panels to withstand high wind and snow loads. Design Criteria: • Applicable Codes=Massachusetts Residential Code,8th Edition,ASCE 7-05,and 2005 NDS • Roof Dead Load=7 psf(Roof A) • Roof Live Load=20 psf • Wind Speed=90 mph, Exposure C • Ground Snow Load=40 psf - Roof Snow Load=28 psf Please contact me with any further questions or concerns regarding this project.
