Completed projects in Somerville: real photos, real prices, one local crew.
Somerville’s mix of triple-deckers, two-family homes and older wood-frame houses all face the same coastal New England weather. We start with a free measurement at your house and finish with a walk-through of the completed work, so you know exactly what to expect.

Somerville’s housing stock is a mix of triple-deckers, wood-framed colonials and capes built between the 1890s and the 1950s, with some newer infill. Most houses sit shoulder to shoulder on small lots, so wind-driven rain off the Mystic River valley and winter ice dams affect rows of homes the same way. The first things we see wearing out are original cedar clapboards that have been painted too many times, asphalt shingle roofs approaching twenty years of nor’easters, and old single-pane windows that let moisture into the wall cavities.
On a typical Somerville house the south and west exposures take the most weather. Siding on those walls fades faster, and roof planes that face the prevailing wind lose granules sooner. Because many homes here share party walls, a roofing or siding job often means coordinating flashing at the property line so water does not find its way between the buildings.
Every job starts with a visit to your house, where a project manager measures the roof or walls and talks through what you want to change. The steps stay the same whether the work is asphalt shingles, James Hardie siding, or both.
In Somerville’s dense neighborhoods, siding has to handle tight lot lines, shade from neighboring buildings and winter moisture. We have installed James Hardie fiber cement on houses here in Mountain Sage and a medium blue. Both colors hold up through freeze-thaw cycles without warping or fading and meet the fire-resistance requirements common in attached and closely spaced homes.
Color and profile affect how the house reads from the street. In a city where many homes sit close to the sidewalk, the choice of lap or shingle makes a noticeable difference in curb appeal. Homeowners we work with in Somerville often want a color that fits the block but stands apart from the tan and white vinyl that dominates some streets. Prefinished Hardie siding arrives with the factory color already baked on. There is no painting on site and no peeling to worry about after a nor’easter.
Roofs here wear out from ice dams at the eaves, wind-driven rain in nor'easters and freeze-thaw cycles, so the details under the shingles matter as much as the shingles themselves. We install GAF and CertainTeed asphalt shingle systems with ice and water barrier along eaves and valleys, synthetic underlayment, and ridge venting to keep the attic dry.

We file it ourselves before the start date. A full roof replacement in Somerville requires a building permit, and we meet the inspector at each required visit. The same applies to siding, window and door replacements that involve structural changes.
Fiber cement siding, such as James Hardie lap or shingle, handles the freeze-thaw cycles and coastal moisture we see in Somerville without warping or rotting. It also meets the fire-resistance requirements that matter on closely spaced multi-family homes. We have installed it on several Somerville projects in colors like Mountain Sage and medium blue.
Most asphalt shingle roofs on Somerville two- and three-family homes are completed in a matter of days once materials are on site, though the schedule depends on the season and the scope. We strip the old roof, install the ice and water barrier and synthetic underlayment, lay the new shingles, and haul away all debris. The town inspection follows the same week.
Yes. When we replace siding or trim on older wood-frame houses in Somerville, we often use AZEK PVC trim boards to replicate the original profiles. The material resists moisture and does not rot, so the details last without the upkeep that wood requires in a coastal climate.
We install GAF and CertainTeed asphalt shingle roofing systems. Every roof we do in Somerville includes ice and water barrier along the eaves and in the valleys, synthetic underlayment over the whole deck, and continuous ridge venting to keep the attic dry through New England winters.
