Roof Cost Calculator

This calculator provides a rough estimate based on average Long Island pricing for 2025-2026. Your actual cost will depend on specific conditions like decking condition, access difficulty, permit requirements, and current material pricing. For an exact quote, schedule a free on-site inspection with ERS Roofing & Siding.

The main factors are roof size (square footage), material choice (3-tab vs architectural vs designer shingles vs metal), roof complexity (pitch, valleys, dormers), and add-ons (gutters, skylights, ice shield). Labor costs on Long Island are also higher than national averages due to licensing requirements and cost of living.

Most Long Island roof replacements cost between $8,000 and $25,000 for a standard home with architectural shingles. Smaller homes (Cape Cods, ranches) are typically $8,000-$14,000, while larger colonials run $14,000-$22,000+. Metal roofing and complex roofs can exceed $30,000.

Permit fees are not included in the calculator estimate. Both Nassau and Suffolk County require roofing permits, which typically cost $150-$400 depending on the municipality. ERS Roofing handles all permit applications as part of our service.
