Project Snapshot 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. Because this was new construction, the work was less about removing an old roof and more about getting every detail right from the beginning. The design called for Owens Corning TruDefinition Duration shingles in Onyx Black, paired with standing seam metal accents on the small eyebrow roofs. The finished combination gave the ADU a clean, modern appearance while still fitting naturally with the surrounding residential neighborhood. What roofing materials were used on this Merrimack ADU? The main roof was installed with Owens Corning TruDefinition Duration shingles in Onyx Black. This deep black shingle color created a crisp roofline and gave the new structure a finished, substantial look. The eyebrow roofs were covered with standing seam metal, adding a different texture and a subtle architectural accent. Rather than using the same material across every section, the combination of asphalt shingles and metal helped break up the exterior and draw attention to the smaller roof details. Why use standing seam metal on eyebrow roofs? Standing seam metal works especially well on small accent roofs because it creates a clean, defined appearance and handles water efficiently on compact roof sections. On this project, the metal accents added visual interest without overpowering the main roof. The smooth metal panels contrasted with the dimensional texture of the Onyx Black shingles, giving the ADU more character from the street. These smaller roof sections are also places where careful flashing and edge work matter. The metal roofing was integrated into the surrounding exterior so that water could move cleanly away from the structure. What is different about roofing a newly constructed ADU? A new-construction roofing project provides the opportunity to build the entire system correctly from the start. The roof deck, underlayment, flashing, ventilation, shingles, and metal details can all be installed in sequence without having to work around layers of older materials or previous repairs. For this Merrimack ADU, our crew coordinated the shingle and metal installation so the different roof sections looked intentional and functioned as one complete roofing system. The straightforward main roof allowed the team to focus on clean lines, proper alignment, and the details around the eyebrow roofs. Those smaller accents ultimately gave the project its most distinctive feature. Who installs roofs on new ADUs in Merrimack, NH?
