From the field observation report,the roof is made of Asphalt Shingle roofing over roof plywood supported by 2X6 Rafters at 16 inches.The slope of the roof was approximated to be 21 degrees. After review 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. Capacity calculations were done in accordance with applicable building codes.
