ADU Roof Pairs Onyx Black Shingles with Metal Accents — Merrimack, NH

Project Overview

Compass Exteriors completed the roofing system on a newly constructed accessory dwelling unit in Merrimack, New Hampshire, located in a neighborhood behind Souhegan Woods Golf Club. This project was different from a standard home reroof because the structure was new construction, which means the crew was working directly from bare decking rather than tearing off old materials. For the roofing, the homeowners selected Owens Corning architectural shingles in Onyx Black with standing seam metal accent panels on specific roof sections.

The combination of dimensional asphalt shingles and standing seam metal gave the ADU a sharp, modern look that complemented the main home on the property. Standing seam metal roofing is a premium upgrade that works particularly well on accent sections, shed dormers, and lower roof pitches where water management and long-term durability matter most. On this project, the metal panels were integrated cleanly into the overall roofing system so the transitions between materials were handled correctly. Onyx Black is one of the stronger shingle color choices for a property that wants a bold, intentional appearance. On a smaller structure like an ADU, a dark roof with metal accents creates a high-end finished look that holds up next to the main home without competing with it. Because this was new construction, the project timeline was driven by the builder's schedule rather than the homeowner's preference, which required Compass Exteriors to coordinate closely with the other trades on site. Roofing on new construction has to be completed at the right point in the build sequence so the structure can be dried in and the interior work can proceed on schedule.
