Commission continues request to replace dormer roof with standing-seam metal; staff worried about mixed roof materials
Summary
An application to replace a lower/dormer roof with red standing-seam metal was continued after staff recommended changing the roofing material or expanding metal across the connected roof to avoid a patchwork of materials; commissioners also raised concerns about low slope, penetrations and long-term performance.
A property owner seeking to replace a lower façade/dormer roof with red standing-seam metal at 80 East Williams Street (COA 2500988) was continued so the applicant can refine the scope and address concerns about mixing roof materials and the roof's low slope.
Applicant Mark proposed a red standing-seam metal roof. HPO staff recommended continuing the application because the main roof is slate and the dormer is a smaller, lower-slope area; mixing metal and slate could create an inconsistent appearance. Commissioners and staff also discussed the roof's low slope, multiple penetrations, and south exposure. Staff recommended specific assembly details (24-gauge metal for visible portions and attention to intake and ridge venting) and said a broader approach — replacing the entire adjoining low roof area or using an asphalt shingle more compatible with adjacent slate — could be appropriate.
Outcome: the commission voted to continue the application to give the applicant time to decide whether to expand metal across the addition or select an alternative shingle and to return with revised materials and scope.
Provenance: the item began with the applicant's presentation (transcript block starting ~5268.695) and the motion to continue was passed later (transcript block ending ~5776.185).
