Roofing, Siding, Decking & Window Contractors in Somerville, MA
Capital Construction Contracting has proudly served Somerville, Massachusetts, and Greater Boston since 2005. We specialize in durable, high-performance exterior upgrades that can handle New England’s demanding climate and accommodate the area’s older homes and compact lots.
From flat roof replacements to window upgrades in triple-deckers, we tailor every project to the needs of the neighborhood. Our fully licensed, insured, and certified crews install top brands like James Hardie, Alside, Trex, and GAF with unbeatable craftsmanship from start to finish.
Reliable Roofing Built for New England Weather
Shortcuts simply aren’t an option when it comes to roof installation in Massachusetts. As a GAF Master Elite® Contractor, we install premium asphalt shingle roofing systems that protect against wind, snow, and ice (and look great doing it). Our GAF systems include underlayment, ridge caps, starter shingles, and ventilation for lasting performance.
Whether you're restoring a historic Somerville home or a newer build, our team delivers stellar results backed by extended warranties. Want authentic slate roofing or a flat rubber system? We can do that, too.
Siding That Blends Performance with Curb Appeal
Capital Construction installs both James Hardie fiber cement siding and Alside vinyl siding, giving homeowners in Somerville flexible options for style and budget. James Hardie is ideal for weather resistance and historical aesthetic, while Alside offers excellent value with minimal upkeep.
Both siding solutions provide:
Excellent resistance to mold, moisture, and rot
Custom styles and colors suited to New England homes
Strong performance in Somerville’s dense, historic neighborhoods
Regardless of the type of siding you choose for your home, you can be assured that we’ll provide smooth, professional installation.
Energy-Efficient Windows & Secure Exterior Doors
Older homes in Somerville often have drafty, outdated windows and doors. Capital Construction offers custom-fitted solutions from top brands like Alside and ProVia that are engineered for tight seals, improved indoor comfort, and better energy efficiency. Not only do our ENERGY STAR®-rated windows and doors help reduce heating costs, but they also add security and lasting charm to your property.
