From the field observation report, the roof is made of Composite shingle roofing over roof plywood supported by 2X4 Trusses at 24 inches. The slope of the roof was approximated to be 19 degrees. After review of the field observation data and based on our structural capacity calculation, the existing roof framing has been determined to be adequate to support the imposed loads without structural upgrades. Contractor shall verify that existing framing is consistent with the described above before install.Should they find any discrepancies, a written approval from SEOR is mandatory before proceeding with install.
