RE: Roof Access Hatch – 203 E Hallam, Aspen, CO 81611
Craig,
We reviewed the as-built framing configuration around the new access hatch opening through the roof in the
upstairs south-east bedroom, as shown in photographs received via email on April 7, 2020. The roof framing
utilizes the south interior wall of the stair to support the short span rafters north of the adjacent existing roof
beam. This interior wall bears down on the existing floor framing below. We understand a new parapet wall will
be framed around the hatch opening, approximately 3’-0” in height, to support the new hatch assembly.
Upon completion of our review of the as-built framing, we find that the roof framing around the hatch is
structurally acceptable as-constructed, and the south interior wall of the stair will provide adequate support for
the tributary roof load. Should you have any further questions regarding this matter, please feel free to contact
our office.
Sincerely,
Evolve Structural Design LLC
