Attn: Mr. Paul Greene, Operations Manager
Re: Structural Assessment Report for Roof Mounted Photovoltaic(Solar)Panel
Installations—Tavares Residence, 4 Marion Road, Salem, MA
AR#3584986
Dear Paul:
` We are providing you with this structural assessment report of Vivint Solar's photovoltaic(solar)
roof installations to be completed at the above referenced dwelling. The assessment criteria are
based upon Vivint's recent dwelling site visit including roof framing photographs and field
notes. We have also reviewed Vivint's PV Solar Permit Submittal, calculations, installation
layouts and notes, PV 1.0 "Site Plan",PV 2.0 "Roof Plan", and PV 3.0, "Mounting Details". All
were supplied for information on the proposed solar panels installation on the dwelling's roof
framing members for our assessment summary.
The dwelling is timber framed of older construction age with an"A"framed main roof, 5% 6"+/-
high,built from nominal 2" x 6" dimensional lumber joists at 16" o/c, typical. There are no other
attached roofs receiving solar panels. The maximum roof joist span length is 14' — 9" +/-
excluding reductions for collar ties supports. Two layers of roof shingles are assumed. Materials
are assumed as minimum Hem-Fir 92 grade, conservatively (low allowable stresses), with
standard construction components (better grade lumber may have been used). 1" x 8" collar ties
are installed at 32" +/- o/c spacing on the joists, set 20" +/- below the top of the 2" x 8" ridge
beam in the main "A" roofs'/attic's full length, in panel installations areas, for minimal roof
reinforcing. There are no other roof joists or ridge beam supports, the full length of roof, down
to framing below. The main attic and roof framing were mostly accessible by access panels at the
site inspection and evaluation, therefore a complete assessment and confirmation of framing
spacing, sizes and condition was able to be performed for this roof.
No architectural drawings were available at the time of this report preparation. Refer to plans
and documents prepared by Vivint for dwelling dimensions, locations and sizes of solar panel
units. The roof framing members were reviewed and checked for their capacity of new loadings.
A. CAPACITY OF EXISTING ROOF TO SUPPORT PROPOSED SOLAR PANELS:
1. Our assessment included using the proposed solar panels dead load that were given to
us in the ZEP calculation sheets and the live and dead loads described below. Our
review of the roof information shows that there are no visible undulations or
unevenness, indicating that the roof framing members are not visibly overstressed
or weakened by past heavy snow loads:
Mr. Paul Greene March 12, 2014 Page 2
2. Given the dwelling's roof construction and condition, the existing roof joists' load
carrying capacity will be able to carry the added dead and redistributed live loads from
'the new solar panels if installed correctly. The dwelling's roof members will also
redistribute the snow live loads, and additional solar panels dead load to the adjacent
framing members. These additional loads should not produce stresses beyond the
allowable stress range for roof framing members assumed as Hem-Fir 42 materials.
Considering the lower roof slopes, array sizes; full access to confirm roof joists' size,
spacing, condition; and smaller collar ties, the panel supports shall be set/attached to
every second joist for lateral installations over joists. No panel supports ap cina shall
be greater than two (2)roof joist spaces, or 32"+/- o/c, to be shown in the PV 2.0
_Roof Layout plan(s). Note—Layout Array Drawing#I submitted for review, shows
every four joists, 64" o/c maximum panel support spacing, and which needs to be
revised to the above spacing. The panel supports do not need to be installed in a
staggered pattern to ensure the proper load distribution, if no more than two rows of
panels are placed on any single roof section, as shown on the plan. After revising,this
layout can be used for permit submittals and installations.
All panels shall be installed as shown on the layout plans with 32"+/- o/c maximum
support spacing, or two ioist spaces and'optionally staggered red to be shown in the final
revised PV 2.0 Roof Layout plan(s), as stated above. Framing member sizes, spacing
_and condition must be properly verified by Vivint installers,prior to any installations.
Send any differing information to this engineer for review and approval, prior to
continuing with any installations.
3. This assessment meets current Massachusetts Building Code, 8`h Edition—Residential
—Amendments to International Residential Code, (IRC), 2009 Edition, for one and
two family dwellings.
B. SOLAR PANEL ATTACHMENT TO ROOF STRUCTURE:
I. The solar panels shall be mounted in accordance with the latest"ZEP Company's
Code Compliant Installation Manual" found on the ZEP website and not included
herein. No additional reinforcing requirements are required for these installations.
However, if during solar panel installations,the roof framing members feel unstable,
or show interior or exterior evidence of minor or excessive movement, then this
engineer should be notified as soon as possible prior to proceeding with installations.
2. Vivint should notify the homeowners that long term build-up of accumulated snow in
the event of extreme snowfall conditions, may produce some roof deflections.
These deflections will be temporary in nature and will not affect the roof s structural
integrity. The solar panels do not need to be cleared of such accumulated snow.
C. WIND UPLIFT LOAD:
1. Refer to attached ZEP calculation sheet for ASCEISEI 7-10 Minimum Design Loads
Mr. Paul Greene March 12, 2014, Page 3
For Buildings and Other Structures, for wind speed at this location of 100 miles per
hour* for Exposure Category `B", and 22 degree roof slopes on the dwelling's roof
areas. Ground snow load is 40 p.s.f* for Exposure `B",Zone 1 (per ASCEISEI 7- 10)
of the roof s interior portion, and effective wind speed of 100 mph*, uplift is shown.
2. Total area subject to wind uplift is calculated for the Interior,Edge and Corner Zones.
A maximum and user selected support(foot) spacing is shown for each location zone.
D. PANEL ANCHORAGES:
1. Maximum allowable pullout per lag screw=235 #/inch from National Design
Standards (NDS)timber construction specifications for Hem-Fir -North lumber
(assumed). Using 4 lag screws, the pullout value is less than 235 #/inch of screw
thread and OK. Considering the variable factors for the existing roof framing
members, and installation tolerances, use a 2 '/2" threaded depth with a minimum
5/16" lag screw per attachment points in roof joists("rafters") components for panel
anchor mounts. This should give a sufficient factor of safety.
E. LIVE,DEAD AND SNOW LOADS:
1. Live load=40 p.s.f. ground snow load; 10 p.s.f attic storage (trusses only)
Dead Load= 10 p.s.f- roofing/framing; 5 p.s.f. -panels, mounting hardware
Total Live Load=40 p.s.f.; Total Dead Load= 15 p.s.f.
2. These values are within acceptable limits of recognized industry standards for similar
structures. The roof members will be able to sustain the solar panel attachments without
damage, if installed in a workmanship like manner according to the above criteria.
We have based our structural capacity determination on applicable building codes, professional
engineering inspection and design experience, opinions and judgments. This report covers this
dwelling's assessment for only the areas for solar panel installations that were made according to
generally recognized structural analysis standards and procedures. The normal structural
engineering industry standard of care utilized for this type of work was used during this report
preparation. The assessments and recommendations in this report were reviewed to ensure a
proper level of quality and uniformity. This report adheres to accepted State and National
practices for current building code standards and can be used for construction purposes.
