To Whom It May Concern,
A jobsite observation of the condition of the existing framing system was performed by an audit team of Direct Energy-MA at
the request of AOstructures, Inc..All attached structural calculations are based on these observations and the design criteria
listed below and only deemed valid if provided information is true and accurate.
On the above referenced project,the roof structural framing has been reviewed for additional loading due to the installation of
the solar PV addition to the roof.The structural review, including the plans and calculations only apply to the section of the roof
that is directly supporting the solar PV system and its supporting elements.The observed roof framing is described below. If field
conditions differ, contractor to notify engineer prior to starting construction.
The roof structure of(All Roof's)consists of composition shingle on roof plywood that is supported by 2x8 rafters @ 20"o.c..The
rafters support a vaulted ceiling with a slope of 30 or 15 degrees.The rafters are supported at the ridge by a ridge beam or load
bearing wall and at the eave by a load bearing wall. The max allowed projected horizontal span is 14'-3". Contractor shall verify
all span are less than 14'-3" prior to starting construction and contact engineer if field conditons differ.
The existing roof framing system of(All Roof's) is judged to beadequateto 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.
Design Criteria:
• Applicable Codes= Massachusetts Residential Code,8th Edition,ASCE 7-05,and NDS-12
• Roof Dead Load= 12 psf(All Roof's)
• Roof Live Load =20 psf
• Wind Speed = 100 mph, Exposure B
• Ground Snow Load=40 psf - Roof Snow Load=28 psf
Please contact me with any further questions or concerns regarding this project.
