A field observation was performed to document the existing framing of the above mentioned address. From
the field observation, the existing roof structure was observed as:
Metal roofing supported by 2x6 Rafter @ 24 in. OC spacing. The roof is sloped at approximately 12
degrees and has a max beam span of 8 ft between supports.
Metal roofing supported by 2x4 Truss @ 24 in. OC spacing. The roof is sloped at approximately 30
degrees and has a max beam span of 6 ft between supports.
