DAA JDESIGN ARCH ITECTURE+INTER IORS 1. An attic access hatch should be installed in the ceiling per code with access provided to all attic areas. 2. The roof structure should be fully evaluated by a licensed structural engineer once access is provided. 3. Hurricane clips (or toe -nails) may need to be added where roof framing members bear on exterior walls to meet the minimum IBC code requirements of today. 4. Collar ties may need to be added in compliance with current IBC code for prescriptive roof framing. 5. Diagonal braces and purlins may need to be added to strengthen the existing rafters to be in compliance with the current IBC code for prescriptive roof framing. 6. v� Additional beams may need to be added in the attic area to support the above -mentioned diagonal braces and purlins. This is mainly needed approximately at the mid -span of the roofs. These beams will require support in the wall system and likely would require new foundation support in the crawlspace and basement. This must be coordinated with a licensed structural engineer. 7. Attic insulation should be added to achieve an R-value as close as possible to current code standards. The maximum insulation possible should be added at the perimeter of the roof as the roof depth in this location does not allow for the minimum required by code. Any energy upgrades, such as increased insulation in the attic, could result in prolonged snow retention on the roof and could ultimately affect roof performance without first completing structural reinforcement. 8. It is not recommended to add additional roofing materials such as an additional layer of shingles, or solar panels without the additional structural support mentioned above. Part of the interior was vaulted in 2023. Steel column in the basement likely supports the exposed ridge beam. 921 MAIN PAGE - 26
