Triple-deckers and pre-war duplexes make up the vast majority of Somerville's housing stock, and each of these multi-story structures presents distinct roofing demands. Steep-pitched slate roofs sit alongside flat membrane systems on the same block, often sharing party walls that complicate flashing details and water management. Freeze-thaw cycling hammers these aging roof systems every winter, cracking sealant joints and pushing ice under shingles at the eaves. For property owners managing buildings that were constructed decades before modern ventilation standards existed, keeping the roof watertight requires an understanding of how these older structures breathe and shed moisture through every season.
Compact lot sizes throughout Somerville mean scaffolding and material staging require careful planning, especially on narrow side yards between buildings. Mature street trees along residential corridors drop heavy leaf loads that clog gutters and accelerate standing water problems during fall and winter months. Ice dams remain a persistent concern on multi-family buildings where heat escaping through shared walls and poorly insulated attic spaces creates uneven snowmelt across the roof deck. Addressing these conditions before they escalate into interior water damage is the difference between a routine maintenance visit and a costly emergency repair.
Replacing a roof on a Somerville triple-decker is a different scope of work than a standard single-family tearoff. Multi-story buildings require additional safety staging, longer material lifts, and close coordination with tenants across multiple units. Decking beneath decades-old shingles often reveals hidden moisture damage that must be addressed before new materials go down. Every replacement project starts with a thorough inspection of the existing roof structure, ventilation pathways, and flashing connections so the finished system performs properly against the heavy snow loads and wind-driven rain that define New England winters.
When a nor'easter tears shingles off a ridgeline or ice dams push water into upper-floor ceilings, Somerville property owners need fast and effective intervention. Emergency tarping prevents further water intrusion while a permanent repair plan takes shape. Ice dam removal using low-pressure steam protects roofing materials from the mechanical damage caused by chipping or salting. These time-sensitive situations demand a crew that can mobilize quickly, assess the full scope of damage, and execute repairs that hold up through the rest of the season without compromising any manufacturer warranties on existing materials.
Flat roofs are everywhere in Somerville, covering the tops of commercial buildings, mixed-use properties, and many older multi-family structures. TPO, EPDM, and modified bitumen membranes each respond differently to ponding water, UV exposure, and temperature extremes. Flashing failures where the roof meets parapet walls, vent pipes, and chimney structures account for the most common leak sources on these systems. Routine inspection and targeted repair of membrane seams, drain assemblies, and perimeter flashing keeps flat roofs performing reliably and extends their useful service life well beyond the point where neglect would force a full replacement.

Frequently Asked Questions
Roofing can be complex, and we’re here to provide answers to common questions. Here are some frequently asked questions from our clients.
Most roofing projects in Cambridge take between one and three days for a standard residential home. Larger multi-family buildings like triple-deckers may require additional time depending on the scope of work, weather conditions, and whether structural repairs are needed beneath the surface material. We always provide a specific timeline during your free estimate so there are no surprises.
Common signs include missing or curling shingles, granule buildup in your gutters, visible daylight through the attic, water stains on interior ceilings, and sagging along the roofline. In Cambridge, freeze-thaw cycling and nor'easter wind damage accelerate wear on asphalt shingles especially on older homes built before modern building codes were adopted.
Yes, most roofing work in Cambridge requires a building permit through the Cambridge Inspectional Services Department. This includes full replacements, structural modifications, and certain repair scopes. We handle all permit applications and ensure your project meets Massachusetts building code 780 CMR requirements so you stay fully compliant.
An asphalt shingle roof in the Cambridge climate typically lasts between 20 and 30 years depending on material grade, ventilation quality, and exposure to coastal weather patterns. Architectural shingles tend to outperform three-tab options by five to ten years. Regular maintenance and prompt repairs after storm events can help maximize the full lifespan of your investment.
Absolutely. If your roof was damaged by a nor'easter, hail, or high wind event, your homeowners insurance policy may cover part or all of the repair or replacement cost. We work directly with insurance adjusters, provide detailed damage documentation, and help Cambridge homeowners navigate the claims process from start to finish.
We recommend scheduling a professional roof inspection at least once per year, ideally in the spring after winter weather has passed. Cambridge homes take a beating from ice, snow, and freeze-thaw cycles each season, and catching small issues early prevents costly repairs down the road. Post-storm inspections are also a smart move after any major weather event.

They replaced our entire roof on our triple-decker in East Cambridge and the crew was professional from start to finish. They handled the permit, cleaned up every day, and the new roof looks incredible. Highly recommend them to anyone in the area.

After a bad nor'easter tore shingles off our roof, they were out within a day to tarp and assess the damage. They walked us through the insurance process step by step and made the whole experience far less stressful than we expected. Excellent work.

We called about an ice dam that was causing leaks into our second floor. They removed it safely the same week and gave us a clear plan to prevent it from happening again. Fair price, honest crew, and they actually showed up when they said they would.
