Historic Preservation Commission <br />Meeting Minutes <br />7 December 2020 <br />Page 3 of 5 <br />Ritchie stated that when a property was landmarked whatever worked with the building code did <br />not necessarily translates to the Alteration Certificate process. <br />Root added that when there are changes in the field during a typical build there could be a letter <br />from an engineer to verify that the change is to the engineer's specifications. Sometimes staff <br />would ask for an engineer letter if they saw something abnormal or not to exact specifications. <br />Those letters generally addressed concerns about structural items like foundations or framing, <br />for issues like snow and wind load. And he noted that if it was cosmetic they would have an <br />architect and planning and zoning take a look at it. <br />Haley asked when the metal roof was noticed in this case. <br />Ritchie stated that she realized there was a metal roof when she did the final inspection. <br />Root added that he did not think the change was noted. He stated that roofing materials were <br />not usually specified in plans unless it was an asphalt roof. <br />Haley clarified that inspectors were not looking for preservation standards. <br />Ritchie confirmed. <br />Root added that inspectors would note if something was not to plan, and he thought that the <br />roof could have been finished at two different times, leading to this issue. <br />Klemme stated that she did not support the color because there was no evidence of painted <br />metal roofs from the time. She thought that there was not strong evidence that there was a <br />metal roof historically on this structure. She added that several manufacturers provided <br />instructions on how to install the shingles at a low slope and offered at least limited warranties. <br />She was not convinced that there wasn't a way to install the asphalt shingles correctly. She <br />noted that with a historic property you may not get the brand -new -house warranty on everything <br />because you were doing preservation and restoration work. <br />Haley and Planner Ritchie discussed that the staff -consulted roofer had stated that it was not an <br />ideal installation product for the situation but it was not greatly concerning. <br />Dunlap stated that the structural integrity of the asphalt roof wasn't in question and the letter <br />from the engineer probably wasn't relevant if the pitch wasn't the same and it wasn't inspected <br />locally. He noted that staff had originally recommended denying the Alteration Certificate and <br />had made it clear that the front 10 feet and the porch should be left intact. <br />Parris stated that she thought it was a dangerous precedent to set if they went with the metal <br />roof because it's already there, without really strong evidence for its being there. <br />Keller stated that he did not think that the metal should be painted. He stated that he was also <br />not convinced that the asphalt would not work. He was torn. <br />Haley stated that there was a lot of compromise as far as the historical structure in the first <br />place, and while this was a small part of the structure, it was a large percent of what was saved. <br />She thought it was reasonable that it could be shingled. She had not heard any evidence that <br />3 <br />
