That is the modeled cost to deliver plus a fair contractor margin, not a sales quote. Built from BLS metro wages, Craftsman labor hours, a real bill of materials, and hand-verified permit data. 2026-08-28
Mid-range here means the reroof most homeowners actually buy: full tear-off and asphalt shingle replacement on a typical single-family roof, disposal included, with up to two sheets (64 sq ft) of decking replacement in the base price. Additional decking prices per sheet. Metal, tile, and slate are the premium rungs of the same job.

The margin is the gap between break even and a typical quote, not a markup we invent. Fair margin moves with trade and market. Most land at a 15 to 22 percent margin on the bid, roughly 18 to 28 percent over the cost to deliver, and free labor does not exist. Full methodology.

Boston roofing sits 20.9 percent above the national average. That gap comes straight from union wage pressure and the endless headaches of working on houses built before 1939. The tools on this page let you check your own quote against real local numbers.
Numbers on this page come from Craftsman labor hours, BLS OES May 2025 wages for Boston, FRED material prices, and the verified local permit fee. Population, income, home values and housing age come from the U.S. Census Bureau (QuickFacts and the American Community Survey); unemployment from the BLS Local Area Unemployment Statistics; building permits from the Census Bureau via FRED. How we calculate
Local Market
Boston roofing costs more because union prevailing wage rates set a high floor for skilled labor. That pressure bleeds straight into residential work. The index shows 71.8 craftsman hours at a loaded wage of $55.71 per hour. That alone puts labor at $4,000. Materials add another $5,077 after FRED PPI adjustment. Add the $196 permit from PermitCalculator.com plus $4,382 in overhead and disposal and you land at a cost to deliver of $13,655. Still, the city average of $17,610 leaves 22.5 percent contractor margin. Boston's median home value of $731,700 keeps demand steady even as the population has declined 0.8 percent since 2020. Contractors here know the old stock will throw surprises. The numbers reflect that reality. (BLS OEWS wage input) (FRED PPI, 2026)
Boston shows almost no population growth and only 521 permits in March. That keeps steady pressure on the existing stock instead of a boom. The labor number reflects those union rates bleeding into residential work. I'd call the a bit more than seventeen five average a steady honest market for what the old houses throw at you. Take a bid right around the floor and I'd say that's fair for what the work is.
Understanding Your Bid
Your bid lands at $17,610 on average for a 2500 square foot asphalt shingle roof replacement (TheFatBook cost index, 2026). The verified floor sits at $15,375. That leaves $2,235 of potential savings between the average and the lowest realistic price. The cost to deliver comes in at $13,655. The 22.5 percent contractor margin is the spread between that delivery number and the city average. Not every bid above the $17,610 average is gouging, but plenty sit too far above the floor. Pre-1939 housing stock creates massive lead abatement and structural leveling demands that newer cities never see. It'll tell you fast whether the numbers add up or if someone padded the unknowns that come with century-old framing.

Cost Breakdown
A typical Boston asphalt shingle roof replacement breaks into clear pieces (Craftsman, 2026). Labor takes 71.8 hours at the local loaded wage of $55.71 per hour which equals $4,000. That loaded rate starts from a $36.53 base BLS wage plus the 52.5 percent burden for taxes insurance and benefits. Materials run $5,077 after tracking the FRED PPI. The permit fee lands at exactly $196. Overhead and site costs add $4,382 for disposal and keeping the business running. Those inputs total $13,655 cost to deliver. The union prevailing wage rates push the labor line higher than most cities. Pre-1939 houses mean crews often find rotted decking or improper step flashing around old chimneys once they start tearing off layers. The city average of $17,610 includes the lean margin on top of that delivery number. Anything well above it deserves hard questions about what exactly is included.
Seventy two hours of labor sounds about right for a full tear off and shingle job on a right about twenty five hundred square foot roof. Especially when you figure the old decking you often find underneath. The loaded wage near fifty six an hour tracks with what union pressure does here. The materials and permit look clean too. Sounds about right.
How to Negotiate
Shop your roofing job in late fall or early spring when demand eases after the insurance rush. Boston winters create a tight window so bids climb when everyone scrambles before the first hard freeze. Know the $15,375 floor and the $13,655 cost to deliver before you talk price. Then ask for the line items on labor hours and material brands. A fair contractor will show the ice and water shield at the eaves for the first six feet plus valleys and penetrations because code requires it. Push gently on the overhead allocation if the total feels heavy. You won't get the floor price but you can close much of the $2,235 gap once you know what the job should cost.
Any bid that leaves off the ice and water shield at the eaves and valleys is a red flag in this town. A fair contractor includes it without being asked because the code is clear. Late fall gives you the best shot at trimming the fat before the spring rush. Ignore the floor and you'll pay more than you should. Walk away if they fight you on the line items.

What Makes This Market Different
Boston roofing carries costs you won't find in newer cities. The combination of a 35.5 percent home ownership rate and a 1947 median build year means most renovation money flows through a small group of owners who will spend on century-old systems. That concentrates pricing power. Union rates set the labor floor and the old timber framing plus multi-layer roofs from the 1920s turn a simple tear-off into a structural puzzle. Even so. Ice and water shield is required by code at the eaves for the first six feet plus all valleys and penetrations. Skip that and the bid is a red flag. I sat with the numbers and the $17,610 average started to make sense only after I saw how often crews hit lead paint or hidden rot that sunbelt crews never touch. The permit is only $196 but the surprises buried in these old houses are what really drive the spread. Still, this market doesn't bid like Atlanta or Phoenix. It bids like a city built before most of us were born.
