Roof
- Adaquate to support the additional imposed loads. No structural upgrades are required.
The following structural design regarding the proposed alterations have been prepared from these assumptions.
The verification of the field observations is the responsibility of the contractor. Prior to commencement of
work, the contractor shall verify the framing sizes, spacings, and spans noted in the sealed plans,
calculations, and/or certification letter and notify the Engineer of Record of any discrepancies.
After review of the field observations and based on our calculations and in accordance with the applicable
building codes and current industry standards, the existing roof structure supporting the proposed
alterations consisting of the solar array has been determined to be:

The existing structure is assumed to have been designed and constructed following appropriate codes at the
time of erection and assumed to have appropriated permits. The calculations performed are only for the roof
framing supporting the solar array installation referenced in the stamped plans and were completed according to
generally recognized structural analysis standards and procedures, professional engineering, and design
experience opinions and judgements. Existing deficiencies which are unknown or were not observed during the
time the site observation are not included in this scope of work. All solar panel modules, racking, and mounting
equipment shall be designed and installed per the manufacturer's approved installation specifications. The
Engineer of Record and the engineering consulting firm assume no responsibility for misuse or improper
installation. This analysis is not stamped for water leakage. Framing was determined on information in provided
plans and/or photos, along with engineering judgement. Prior to commencement of work, the contractor shall
verify the framing sizes, spacings, and spans noted in the stamped plans, calculations, and/or certification letter
and notify the Engineer of Record of any discrepancies prior to starting construction. If during solar panel
installation, the roof framing members appear unstable or deflect non-uniformly, our office should be notified
before proceeding with the installation. The contactor shall also verify that there are no damage/deficiencies
(i.e., dry rot, water damage, termite damage, framing member/connection damage, etc.) to framing that was not
addressed in the stamped plans, calculations, and/or certification letter and notify the Engineer of Record of any
concerns prior to starting construction.
Lucent Engineering, P.C.May 16, 2022
Should you have any questions regarding this letter or if you require further information, do not hesitate to
contact me.
Considering the existing roof's slope, size, spacing, condition, and calculated loads, the panel bracket
supports shall be placed no greater than 48 in. o/c.
Panel supports connections shall be staggered to distribute load to adjacent trusses.
Solar panels shall be designed, mounted, and installed in accordance with the most recent ''Ironridge
Manual'', which can be found on the Ironridge website (http://ironridge.com).
Based on the information supplied to us at the time of this report, on the evaluation of the existing structure, and
solar array panel bracket connection, it is our opinion that the roof system will adequately support the additional
loads imposed by the solar array. This evaluation conforms to 2018 IRC and current industry standards.
