Chittenden County, residential-and-commercial mix. Suburban-pattern lots make most projects straightforward — fewer historic constraints than Burlington proper. Roofing in Williston runs at 1.05-1.15× statewide median. Get bids that know the Williston reality, not generic Vermont pricing.
Williston runs 1.05-1.15× of statewide median for roof replacement work. Mid-2026 numbers, with Williston adjustments.
Asphalt shingle roof replacement — $8,000-20,000 statewide median (architectural shingles preferred for Vermont wind/ice loads; 1,500 sq ft ranch in Burlington runs $9,000-13,000). Standing seam metal roof — $20,000-40,000 statewide median (sheds snow naturally, resists ice dams, 40-70 year lifespan).
In Williston, multiply by 1.05-1.15×.
The cost driver in Williston is the age of the housing stock — pre-1960 homes need supplementary scope (electrical service upgrade, plumbing modernization) on top of the headline service. Get three written bids and ask each one to break out the supplementary scope they expect.
GMP territory. Standard GMP and EVT rebate stack applies. Most Williston homes built 1985-2010 — newer construction, fewer surprise weatherization items, but also less dramatic weatherization payback.
Roofing itself rarely qualifies for rebates, but if you are planning solar in the next 10 years, this is the moment. Vermont solar+battery stacks the federal Section 25D 30% credit plus EVT $0.40/Wh battery incentive plus Net Metering Group 2 — and replacing the roof first avoids $4,000-12,000 in solar removal/reinstall costs later.
Trap: the contractor whose bid quotes a rebate stack from a different utility territory. Ask them to break out each rebate by name and confirm in writing which ones apply to Williston (Green Mountain Power (GMP)). Bids that show "$X off after rebates" without naming the rebates are the ones that lose money on the actual paperwork.
Vermont roofing season is late April through mid-October. Mud season ends and crews can stage materials; first snow makes most asphalt installs impractical by late October. Booking a roof in May for July is realistic; booking in July for September is risky.
Vermont winters punish roofs differently than other regions — snow load, ice dam pressure, and freeze-thaw cycles. Ask about Vermont-specific experience: ice dam mitigation, ventilation upgrades during reroofs, and snow-load engineering for steeper pitches. The cheaper out-of-state crew that doesn't know Vermont winters costs more long-term.
Vermont-specific: Williston has stronger contractor density than rural Vermont, so expect 4-6 serious bids in a typical project. Use the variance to identify the bid that's missing scope (cheapest, often) and the bid that's overpriced for Williston (most expensive, often).
