Prices reflect Long Island market rates as of 2025. Actual quotes depend on roof pitch, waste factor, number of layers removed, deck condition, and local permitting costs.
What's Included in a Roof Replacement
A quality roof replacement from a licensed Long Island contractor includes:
- Tear-off and disposal of existing shingles (price varies if multiple layers)
- Deck inspection and repair of any rotted or damaged sheathing
- Ice and water shield along all eaves, valleys, and penetrations
- Synthetic underlayment over the full deck
- Drip edge on all rakes and eaves
- Shingles with manufacturer's material warranty
- Ridge cap installation with proper ridge vent
- Flashing replacement at chimney, skylights, and walls
- Cleanup and haul-away of all debris
- Workmanship warranty
What Affects the Final Price
- Roof pitch (steepness). Steeper roofs require more safety equipment. Pitch multipliers can add 15–40% to base costs.
- Number of layers being removed. Nassau County code generally allows a maximum of two layers before full tear-off is required.
- Deck condition. Rotted plywood decking adds $70–$120 per 4x8 sheet replaced.
- Chimney and skylights. Every penetration requires custom flashing work.
- Permits. Most Long Island municipalities require a roofing permit ($150–$400).
