Historic Commission reviews proposal to replace slate roofs with asphalt shingles in Bangor

The Bangor Historic Preservation Commission faced a pivotal discussion on April 19, 2025, regarding the proposed replacement of slate shingles on the Pitcher House and its stable with asphalt shingles. The applicant argued that the slate shingles are beyond repair, citing significant deterioration and leaks that render reinstallation impractical. "The majority of the existing shingles will most definitely break and deteriorate even further during removal," the applicant stated, emphasizing that nearly 90% of the shingles are damaged.

Commission members expressed concerns about the sustainability of asphalt compared to slate, with one member noting that slate roofs are generally more durable and environmentally friendly. The applicant countered that modern asphalt shingles come with a lifetime warranty and are more cost-effective, stating, "The cost to replace the slate would exceed 3 to 4 times that of the pro slate line with no warranty as to workmanship."

The discussion highlighted the tension between preserving historical integrity and addressing practical maintenance challenges. While some commission members advocated for retaining slate roofs wherever possible, the applicant maintained that the financial burden of maintaining slate was unsustainable. "The cost required to maintain and preserve such a home is significant," the applicant noted, underscoring the risk of losing historically valuable homes if upkeep becomes financially unfeasible.

As the commission deliberates, the outcome could set a precedent for future preservation efforts in Bangor, balancing the need for historical authenticity with the realities of property maintenance. The decision on the Pitcher House's roofing will be closely watched by both preservationists and homeowners in the historic districts.
