Anthony,
The Versico VersiWeld TPO root system installed at the above referenced location was installed per
standard Versico specifications and details. At this time the Verslco roof should be performing as
intended and designed. Care should be taken to maintain the VerslWeld roof membrane since It was
noted that the roof had tree branches, broken battles and cigarette butts on the membrane that could
be harmful to the long term performance it.
Please feel free to call me should you have any further questions at 303-469-8400.
Sincerely,
Y

Dear Mr. Simpson,
Q'IV O ■'•J)r-I..n.:
-/3
Per your request, we conducted a site visit to the above referenced site on February 25, 2013. The
purpose of this site visit was to observe the newly installed flat roof system and review the design
strength of the existing roof framing.
The new roof consists of a flat roof covered with a membrane roof system. This new roof system
does not slope to the perimeter scuppers like the original roof system sloped. The new roof system
was installed flat with two interior roof drains with secondary over flow drains. The original scuppers
are still in place.
There was melted snow on the roof at the time of our observation. We observed about 'A" of
ponding occurring around the primary drain. The secondary drain is approximately 1"higher then the
primary drain. The overflow scuppers are approximately 4` higher then the primary drain.
Based on these ponding depths, the maximum roof deflection and the weight of the rain water, the
maximum ponding depth does not exceed the weight of the snow load in this area so the roof
framing is still adequate for the anticipated loading.
This report is based upon our site observations, a review of the documents provided (if any), and our
experience with projects of this type. Our observations were limited by the presence of backfill, wall
and ceiling coverings, and other finishes. Unseen defects may exist which could affect the
performance of the structure. We believe this investigation was conducted with the level of skill and
care used by structural engineers practicing in this area at this time. No warranty, express or
implied, is made.
Thank you for selecting CTLITHOMPSON for your engineering needs. When we can be of
additional service. please contact the undersigned.
Very truly yours,
