Whereas other pricing guidelines are national, this one focuses on what Boston siding and roofing contractors are observing on current projects being undertaken in the Greater Boston region in 2026. This guide does not attempt to predict the cheapest renovation but provides realistic numbers for a full exterior remodel budget.
What Counts as a Full Exterior Renovation?
A full exterior remodel normally includes four major changes in one remodeling project: roofing, siding replacement, new window installation, and entry door replacement. Combining all of these improvements often helps avoid delays and do all exterior remodeling in one construction schedule.
Cost by Component: Roofing, Siding, Windows, and Doors
Roofing constitutes the largest share of the exterior renovation cost in Boston. Roofing replacement in a house of 1,500–2,500 sq. ft. costs approximately $8,000-$18,000.
The siding is generally the second-most expensive element of the project. The cost of combined projects like roofing and siding in Massachusetts today varies. For siding, it is approximately between $4–$9 per square foot for vinyl siding and $9–$14 per square foot for fiber cement siding, inclusive of labor.
In most cases, the window and door replacement cost in Boston will be defined by the choice of materials rather than by the installation process itself. Thus, double-hung replacement windows normally cost $600–$1,100 each, and a typical entry door normally ranges from $1,500 to $3,500. Custom glass options make the prices higher.
As a result, when these elements are put together, home renovation costs in Boston in 26 usually end up between $35,000 and $75,000 or even higher.

As you consider what needs to get done prior to starting construction, permits need to be included in the cost planning process. In Boston, a complete tear-off of the roof will probably involve seeking the permission of the Building Department, but like-for-like window replacement may not necessarily entail a permit if existing openings are maintained.
Many people also opt to do their projects in phases, completing the roof now and then planning to do siding and windows in future seasons. For individual planning needs, the expertise of Boston siding and roofing contractors could prove invaluable.
FAQ
How much does a full exterior renovation cost in Boston in 2026?
A complete exterior renovation—including the roof, siding, windows, and entry door—typically costs between $35,000 and $75,000+ in the Boston area. The final investment depends on home size, material selection, and whether premium products are included.
Do I need a permit for a full exterior renovation in Boston?
Usually, yes, for the roofing portion of the project. A full roof tear-off generally requires a Boston Building Department permit, while replacing windows within their existing openings typically does not, unless structural changes are made.
Should I renovate my roof, siding, and windows together or in phases?
Both approaches can work, but phased renovations are common. Many homeowners replace the roof first because it protects the rest of the structure, then schedule siding and windows as a separate project when the budget allows.
