About this file
This document is a site layout and associated plans PDF for the Buttrick Cottage and Carriage House Roof Replacements project at Minute Man National Historical Park in Concord, Massachusetts, dated 6/22/2025. The plans provide detailed technical specifications for a comprehensive roof replacement, including:
Key technical details include replacing roof shingles with 3-tab asphalt shingles, installing waterproof self-adhering underlayment, replacing wood gutters with 5-inch 16-20oz copper half-round gutters, and implementing copper flashing and downspout modifications. The project involves meticulous preservation of historical elements, with specific instructions to minimize damage to original building components. The site plan shows the location of the Buttrick Cottage and Carriage House, staging areas, contractor parking, and designates an area to remain open for park staff during construction.
