The representative from Coastal emphasized that the CertainTeed brand solar shingles would require the removal of existing roofing materials as they are part of a complete roofing system. The commission members delved into the details, comparing this technology to competitors like Tesla and discussing the necessity of adhering to Massachusetts’ specific regulatory and installation requirements, such as those concerning water runoff, debris collection, and power storage limitations.

Another focal point of the meeting was the proposal to update the commission’s guidelines to address mechanical elements like air conditioning units and generators.

The conversation also extended to the topic of extending the commission’s oversight to include walls, fences, and the color of roofs. This idea received a polarized response when presented at a neighborhood association meeting.

Moreover, the commission’s $50 application fee for a certificate of appropriateness came under scrutiny. Suggestions were made to explore a percentage-based fee structure relative to the proposed work’s cost to make the process fairer and more accessible.

The meeting also touched upon the broader challenges faced by the commission, such as the approval process for alterations to historical structures and the search for new commission members. The effectiveness of endorsements from local organizations, such as the Historical Society, the American Institute of Architects, and the Board of Realtors, was discussed in the context of recruiting new members.

In reviewing the commission’s governing documents, including bylaws and the commission’s powers in surveying historic buildings and sites, members acknowledged the need for careful coordination with the Town Council, especially in light of a lawsuit the town faced in 2015.

The meeting concluded with a reminder to the members about the importance of mindful communication and discretion during discussions, considering the public nature of the meeting records.
