Removing old roofing materials can cost between $1 and $5 per square foot, depending on the number of layers and the type of material. Disposal fees may also apply.

If your roof deck is damaged or deteriorated, it will need to be replaced, which will add $2 to $7 per square foot.
5. Labor and Permits
Labor costs in Westchester tend to be higher than national averages. Permits can cost anywhere from $150 to $500, depending on your municipality.

Residential vs. Commercial Roof Costs: Key Differences Explained
Understanding the distinction between residential and commercial roofing costs is essential when planning a new installation or replacement.
Residential Roofs
Residential roofs typically involve steeper slopes, smaller surface areas, and more aesthetic considerations such as color, texture, and curb appeal.
- Standard Materials: Asphalt shingles, wood shake, or synthetic roofing.
- Accessibility: Easier access leads to lower labor costs.
- Design Complexity: Features such as chimneys, skylights, and dormers may add to complexity.
- Average Cost Range: $6,500 – $20,000, depending on the size and materials used.
Best for: Single-family homes, townhouses, and small multi-unit properties.
Commercial Roofs
Commercial roofs are often flat or low-sloped and span larger surface areas, requiring specialized materials and equipment.
- Standard Materials: TPO, EPDM, PVC, or modified bitumen.
- Installation Requirements: More complex due to the presence of HVAC units, drainage systems, and safety regulations.
- Durability & Access: Built for foot traffic and long-term durability.
- Average Cost Range: $10,000 – $40,000+, based on square footage and system type.
Best for: Warehouses, office buildings, schools, and retail centers.
Types of Commercial Roofing Materials & Their Costs
When planning a commercial roof replacement in Westchester, understanding the materials available is essential. Your roof’s design—flat or sloped—will largely determine your choices. Below is a guide to the most popular commercial roofing materials, their pros and cons, and estimated installation costs in 2025.
Flat Roofing Systems
Flat roofs are common in commercial buildings due to their cost-effectiveness and ease of installation. However, material choice plays a big role in durability and maintenance needs.
| Material | Pros | Cons | Average Cost/Sq. Ft. |
| EPDM (Rubber) | Easy to install, affordable, long-lasting | May shrink or puncture over time | $3.25 – $14.75 |
| TPO (Thermoplastic) | UV resistant, energy-efficient, lightweight | Quality may vary by manufacturer | $3.50 – $14.00 |
| PVC Roofing | Chemical-resistant, fire-retardant, durable | Higher cost than EPDM | $4.00 – $12.00 |
| BUR (Built-Up Roof) | Proven track record, multiple protection layers | Heavier, longer installation time | $4.00 – $10.00 |
| Modified Bitumen | Durable, suitable for high-traffic areas | Needs heat application, costlier option | $11.50 – $14.50 |
| Green Roofing System | Eco-friendly, improves insulation & aesthetics | Expensive, needs structural planning | $10.00 – $30.00 |
Additional Cost Factors for Commercial Roofing in Westchester
Beyond the materials, your total project cost is influenced by building accessibility, structural needs, and site-specific challenges.
Roof Access
- Property Access: Limited access to the roof can increase equipment and labor costs.
- Building Height: Taller structures (four or more stories) often require cranes or lifts, which significantly increase costs.
- Occupancy Status: Projects on hospitals, offices, or apartments often need off-hour labor to minimize disruptions, which adds to labor costs.
- Material Storage: Sites without nearby storage or “lay-down” areas may face logistical challenges, impacting time and cost.
What’s Underneath the Roof Matters
Every roof has multiple layers beneath the surface. These impact both performance and pricing.
- Roof Structure (Decking): Wood, or concrete decks may need repairs or full replacement. Costs can spike if damage from moisture or age is present.
- Insulation: Upgrading or replacing insulation (recommended every 15 years) improves energy efficiency and can lower utility bills.
- Cover Boards: These boards add strength and fire resistance. Skipping this step can reduce durability.
- Other Substrate Materials: Additional layers, such as plywood, solid timber, or spray foam, may be required depending on local building codes or the type of structure.
Alternatives to Full Roof Replacement
Not every situation requires a complete tear-off and replacement. Here are cost-saving alternatives:
Roof Re-Covering
- Adds a new layer on top of the existing one.
- Suitable if your roof has only one layer and no water damage.
- Lower cost than full replacement, but limited by local building codes (typically, a maximum of two layers).
Roof Coating
- Involves applying a liquid membrane to the existing surface.
- Extends the roof’s lifespan by enhancing its resistance to weather and UV.
- Ideal for structurally sound roofs without insulation issues.
Final Thoughts: Choosing the Right Commercial Roofing Option
Each commercial roofing system has its strengths, but the best choice depends on your building type, budget, and long-term goals. Material selection, roof access, and what’s beneath the surface all play critical roles in determining the final cost.
