Most full asphalt roof replacements in Westchester County land between $12,000 and $25,000 in 2026 — roughly $450–800 per square (100 sq ft) installed, tear-off included. Metal and slate sit well above that and have their own guides. The spread on asphalt is mostly three things: how steep and cut-up the roof is, what the deck looks like once the old shingles come off, and which shingle tier you choose.
Here is where the money goes on a typical 20–30 square single-family home. Every Summit Roofing Co estimate is a fixed written number after we have been on the roof — these ranges are what jobs actually run across Westchester County this year.
| Line item | Typical range | What drives it |
|---|---|---|
| Tear-off & disposal | $1,500–3,500 | One layer is standard. A second layer underneath adds labor and dumpster weight — and is common on homes that were last roofed cheaply. |
| Architectural shingles & accessories | $5,000–10,000 | Shingles, starter, hip and ridge cap, and matched ridge vent. Designer or impact-rated shingles push the top of the range. |
| Underlayment & ice-and-water shield | $1,200–2,500 | Ice-and-water membrane at eaves, valleys, and every penetration; synthetic underlayment everywhere else. Non-negotiable in this climate. |
| Deck repair | $0–3,000 | Priced per sheet only where plywood is soft. Most roofs need a few sheets; roofs with long-ignored leaks need more. |
| Flashing, chimney & skylights | $800–3,000 | New step and counter-flashing, pipe boots, and chimney cricket. Reusing old flashing is where most premature leaks come from. |
| Labor, permits & cleanup | $3,500–7,000 | Certified installation crew, municipal permit, and magnetic nail sweep of the property. |
Typical asphalt roof replacement: $12,000–25,000 installed ($450–800 per square)
A simple gable roof installs fast. Steep pitches, multiple dormers, valleys, and hips add staging time and waste — a cut-up roof can cost 30–40% more than a plain one of the same size.
A second layer, rotten decking, or missing ventilation all show up during tear-off. We photograph what we find and price deck work per sheet in writing before it is replaced.
Standard architectural shingles carry a 30-year to lifetime limited warranty. Designer and Class 4 impact-rated lines cost $1,500–4,000 more on a typical home and can lower insurance premiums.
Spring and fall book out weeks ahead. Late-fall and winter installs are possible in dry weather and often price better.
Most single-family asphalt roofs run $12,000–25,000 installed — about $450–800 per square. Larger, steeper, or cut-up roofs and premium shingles sit above that; metal and slate are separate price tiers.
Always. We strip to the deck on every replacement — overlays hide rot and void most manufacturer warranties. Disposal is in the number.
Only if the roof was damaged by a storm event. Age and wear are not covered. If there is storm damage, we document it and meet your adjuster on the roof.
Yes. Financing is available on every replacement, and the fixed written price means the amount you finance is the amount you pay.
