Manchester's humid continental climate brings heavy snow loads that demand reinforced curb framing and double-sealed flashing around every skylight curb. Homes in the North End and Rimmon Heights often feature steep asphalt-shingle roofs from the early 1900s that require sistering rafters before any curb is set. Installing without accounting for these loads leads to sagging and eventual leaks that travel down into plaster ceilings.
We route all new skylights through existing attic spaces in West Side and Bakersville colonials while preserving insulation depth to meet current energy codes. Tubular units work well in Hallsville capes where roof pitch limits full-size units. Every curb receives ice-and-water shield extending four feet up the slope, a step that prevents the ice dams common along the Merrimack River corridor near Amoskeag Falls.
Coordination with Manchester building inspectors is required when cutting through rafters in pre-1950 structures found around the Amoskeag Millyard and South End. We pull permits and schedule the required framing inspection before shingles are disturbed. This avoids the stop-work orders that occur when contractors skip the structural review on older balloon-framed homes.
Technician insight
In Manchester, the thing that catches most people out with Skylight Installation is underestimating snow load on the steep roofs common in the North End and Rimmon Heights. Older balloon framing often needs sistering that homeowners don't expect, and skipping it leads to sagging curbs after the first heavy winter.
West Side Colonial Skylight Addition
Homeowner wanted natural light in a second-floor hallway but the 1920s roof had 2x6 rafters spaced 24 inches. We sistered three rafters, built a 6-inch curb, and flashed with ice-and-water shield. The unit passed inspection and has remained leak-free through two winters.
