Service Offerings: the exterior work a Massachusetts house asks for
The six exterior jobs that come up on a house in northeastern Massachusetts, what each one does, and where each one tends to stall.
Six jobs, one house, and an order to think in
Most exterior questions come down to one of six jobs: the roof covering, the gutters, the siding, the windows and doors, the decks, and the winter work that keeps ice off the eaves. The jobs overlap more than their names suggest. A leak at a window can look like a roof problem, and an ice dam can be fed by heat escaping from the attic. This page describes the work itself, not any company that does it.
Where each job tends to stall
The roof covering
Basic three-tab asphalt shingles need replacing about every 20 years, according to a 2010 Fine Homebuilding article. The same piece says modern shingles are marketed at 40 to 50 years but gives no field data for that, so we treat the higher figure as a claim. A lifetime warranty is prorated after the first 10 years.
Gutters and downspouts
A 5-inch K-style gutter is sized for up to 5,520 square feet of drainage under moderate rain, according to This Old House. The same guide allows about one square inch of downspout for every 100 square feet of roof, and two outlets on any run of 60 feet or more.
Siding
The 2025 Cost vs. Value report prices a New England vinyl siding replacement at an average of $17,590, and fiber cement at $20,678. Installed below 40 degrees Fahrenheit, vinyl needs its corner gaps widened to 3/8 inch, as the vinyl industry's installation manual sets out.
Windows and doors
A Mass Save rebate pays $75 per window when single-pane windows are replaced with ENERGY STAR Most Efficient windows certified for the north region. Purchases must fall in 2026, with applications in by February 28, 2027, and double-pane replacements do not qualify. The sources behind this page do not price doors, so none are priced here.
Decks
The same report puts a composite deck addition at an average of $25,817. That is the cost of a new deck, not of replacing one that already stands. Whether a deck needs a permit is a question for the town building department.
Winter roof work
An ice dam needs snow on the roof, heat from the house and cold at the eave, as UMass Amherst puts it. Remove one and the dam stops, which is why the fix starts in the attic. The model residential code asks for an ice barrier reaching 24 inches inside the exterior wall line, as Fine Homebuilding explains. Heat cable manages the symptoms rather than curing them, according to NDSU Extension.
Putting the list to work, in order
Start with the job that lets water in, then the parts that only show. Before any contract is signed, ask the town's building department whether the work needs a permit, because each town decides whether a roofing, siding or window job counts as an ordinary repair.
Then read the written contract. For an owner-occupied home of one to four units in Massachusetts, the home improvement contract law requires it to be in writing, to carry the contractor's registration number and a scheduled completion date, and to cap the deposit at one-third of the price, with an exception for certain special-order materials. If a judgment goes unpaid, the Guaranty Fund can pay up to $25,000, but only to an owner who signed a written contract with a registered contractor.
Watch a flat commercial installation, in sequence
Flat commercial roofs are the one kind of roof this page touches only at the edge. The clip below is a roofing channel's recording of a commercial installation, labelled step by step. It shows a flat roof on a commercial building, not a pitched house roof, so the steps for a house will differ.
The figures a reader can check against the sources
Each figure below is a regional average for one defined reference job, from the 2025 report named in its row. None is a quote, and none describes a particular house.
| Job | Average cost | Resale value recouped | Period | Source |
|---|---|---|---|---|
| Asphalt shingle roof replacement | $35,701 | 62.6% | 2025 | Cost vs. Value 2025, New England |
| Vinyl siding replacement | $17,590 | 92.7% | 2025 | Cost vs. Value 2025, New England |
| Fiber-cement siding replacement | $20,678 | 144.9% | 2025 | Cost vs. Value 2025, New England |
| Vinyl window replacement | $21,922 | 71.2% | 2025 | Cost vs. Value 2025, New England |
| Composite deck addition | $25,817 | 95.8% | 2025 | Cost vs. Value 2025, New England |
| Recouped is the resale value the report returns, as a share of the job cost. A deck addition is a new deck, not the cost of replacing one. | ||||
