What a full replacement costs in 2026
These ranges assume a typical single-family home, single-layer tear-off, new underlayment and flashing, and a Connecticut-registered installer. Fairfield County labor runs among the highest in the state, so county quotes typically land in the upper half of statewide ranges.
| Material | Typical full replacement | Life in CT |
|---|
| Three-tab asphalt | $9,000–$15,000 | 15–20 years |
| Architectural asphalt | $11,000–$20,000 | 25–30 years |
| Designer architectural shingles | $16,000–$30,000+ | 30–50 years |
| Standing seam metal | 2–3× asphalt on the same roof | 50+ years |
| Flat / low-slope membrane (TPO, EPDM) | Priced per square; varies widely by system | 20–30 years |
Published Connecticut guides put a typical architectural asphalt job for a 2,000-square-foot roof in the $11,200–$20,700 band, and Stamford-specific guides put the same job near $12,600–$18,500 — consistent with the ranges above once pitch, dormers, and shoreline detailing are counted.
What moves your quote
- Roof size and pitch. Contractors measure in squares (100 square feet of roof surface). Steep pitches and cut-up roofs with dormers and valleys add labor and waste, sometimes 20% or more over a simple gable.
- Tear-off layers. Two old layers cost more to remove and dispose of than one, and dumpster and disposal fees are a real line item in Fairfield County.
- Deck repair. Rot found under old shingles — common around chimneys, valleys, and bathroom vents — is replaced per sheet. Get the per-sheet price in writing before tear-off day.
- Coastal detailing. Corrosion-rated fasteners and flashing add roughly a few hundred dollars per roof near the Sound; high-wind shingle upgrades add roughly $2,200–$3,600 over standard architectural.
- Ventilation and insulation fixes. A new roof over a poorly ventilated attic will ice-dam again. Ridge vents, soffit intake, and baffles are cheap during a replacement and expensive afterward.
- Permits. Town permit fees in the metro run roughly $150–$700 depending on the town and the job; check your town's current schedule rather than trusting a quote's estimate.
What to demand in every written quote
- Shingle brand, line, and wind rating — not just "architectural shingles."
- Nails per shingle and fastener type, especially within a mile of the Sound.
- Ice-and-water shield coverage: eaves, valleys, and every penetration, with the eave run carried past the interior wall.
- Underlayment type (synthetic is the Connecticut standard; felt is the budget option).
- Flashing scope: all new step, chimney, and valley flashing, or exactly what is reused.
- Ventilation plan and warranty terms: manufacturer warranty versus the contractor's workmanship warranty, in years, in writing.
Watch out for the low outlier. A bid thousands below the rest usually omits something — deck repair allowance, new flashing, ice-and-water shield scope, or permit fees. Compare line items, not just totals.
