Starting Over With a New Roof
A full replacement means every old layer comes off, the wood deck gets a close look, weak boards are fixed, and a new roof goes on from there. Many Buffalo homes add a steep Victorian or Queen Anne gable, dormers, and sometimes three generations of shingles.
Many owners here live in one half of a two-family double, so a single roof covers two households. Some older city houses still wear slate, which costs far more to replace than shingles. This site is a free referral service, not a roofing company: the roofer who gets your request does the inspection, the estimate and any work you hire it for.
When Homeowners Ask for Full Roof Replacement
- Old layers piled up. Taking every layer off shows the true state of the deck and lifts extra weight off the rafters.
- Ice dams every winter. A new roof is the moment to fix the eave protection and attic airflow behind them.
- A dip in the roofline. A sagging ridge or soft spots can mean a damaged deck, so ask for a close check before any quote.
Rough Numbers for Full Roof Replacement
These installed costs per square foot come from a statewide New York guide for 2026. Nobody has published a Buffalo-only figure, so treat the rows as a starting point.
| Cost row | Figure | Source (year) |
|---|---|---|
| New York 3-tab shingles, per sq ft | about $6.70 | RoofObservations, 2026 |
| New York architectural shingles, per sq ft | about $7.40 | RoofObservations, 2026 |
| New York premium shingles, per sq ft | about $9.20 | RoofObservations, 2026 |
| New York exposed-fastener metal, per sq ft | about $9.90 | RoofObservations, 2026 |
| New York standing-seam metal, per sq ft | about $15.30 | RoofObservations, 2026 |
Steep gables, dormers and slate removal lean toward the upper half, and extra layers, ice-and-water shield, new decking or a permit can each be a separate line. The cost calculator turns your home size and pitch into a rough range.
What Happens on the Day
- Tear-off. Every layer comes off down to the deck, with the old underlayment and tired flashing.
- Deck check. Ask for photos of the bare boards. Rotted sections get replaced, usually as a priced extra.
- Eave protection. Ice-and-water shield runs along the eaves and valleys before the underlayment goes down.
- Airflow. Soffit intake and ridge exhaust keep the attic cold, which helps head off ice dams.
- New roof and cleanup. Shingles or metal go on with fresh flashing, then a magnet sweep for nails and a walk-through with you.
Sort out permits before the dumpster arrives. Ask your roofer if a City of Buffalo permit applies and which of you will apply; Permit & Inspection Services (716-851-4972) can confirm. In Amherst, NY the roofing permit has to clear before anyone starts, and re-roofing in the Town of Tonawanda, NY calls for a building permit. Elsewhere, ask the town, or your village office first. Landmarks and houses in the city's preservation districts may also need Preservation Board review.
Why Start Your Request Here
- One company calls you back. A single independent roofer gets your request, not a list.
- Room to change your mind. New York requires a signed, plain-English contract for jobs over $500, and a written notice sent by midnight on the third business day after you sign ends the deal.
- No cost to you. A roofer may pay this site for the referral. You pay nothing and get nothing in exchange.
At the inspection, request the company's City of Buffalo contractor license number (for Amherst or Town of Tonawanda homes, its town registration) and verify it with the issuing office. Also ask for proof of liability and workers' comp coverage, references, and written manufacturer and labor warranties, with the manufacturer warranty registered.
Frequently Asked
Can the new roof go over my old one?
It depends on the town and the layers already there. Amherst caps an overlay at two layers in total. The Town of Tonawanda allows a new roof over only one existing layer; past that, it gets stripped to the sheathing. Even where an overlay is allowed, a tear-off is the only way the roofer can see the deck itself.
How does a replacement work on a two-family double?
One roof covers both flats, so give your tenants or the other household the dates early. The roofer may need attic access through the upper unit. Ask whether the low-slope rear roof is part of the job and what material it gets.
My house has slate. Does it have to go?
Not always. Broken slates can often be swapped one by one, while a whole new slate roof costs far more than shingles. On a landmark or in a preservation district, switching materials may also need review. See roof repair for the repair side.
How much should I pay before work starts?
A New York roofer can't require a deposit. Materials may be billed on delivery if that cost was disclosed in writing. Anything you hand over before the work is done has to sit in a trust account, unless a bond or letter of credit covers it instead.
