Commercial Roof Cost Guide for Central PA: 2025 Edition

Commercial Roof Cost Guide for Central PA: 2025 Edition

If you're budgeting to replace the roof for your business, you've likely hit one major wall: "How much is this actually going to cost?"

It's one of the first and most important questions building managers, facilities directors, and business owners ask—and for good reason. Commercial roofs are a major investment, ranging from $50,000 to $500,000 depending on their size, materials, complexities, and warranties. 

For such a large cost, you’ll typically need to submit estimates for approval. This creates a back-and-forth between the contractor and your higher-ups, with you in the unfortunate middle. But what if you could get a range approved before you even began meeting with roofing companies? 

Equity Commercial Roofing has worked with hundreds of facility directors across Pennsylvania to navigate the cost complexities of commercial roof replacement. In this guide, we’ll walk through actual price ranges, materials, warranty options, and more—so you can plan and get approvals faster.

How Much is a Commercial Roof Repair? 

Roof repair costs vary widely depending on the size and complexity of your roof and repair issue. Leaks, in particular, can have a large cost range. 

Costs for Common Roof Repairs

Repair Typical Cost
Small Roof Leak $1,200 to $2,500+
Severe Roof Leak $5,000 to $10,000+
Pipe Boot $900 to $1,000+
Popped Nails $1,800+ 
Ridge Vent $1,500+
Wind Damage $800+

 

How Can I Calculate a Roof Replacement Cost? 

How Can I Calculate a Roof Replacement Cost? 

Below is a breakdown of price ranges by material type and building size:

Flat Roof Costs by Size

Material Small Buildings
(5,000–7,000 sq ft)
Medium Buildings
(20,000–40,000 sq ft)
Large Buildings
(100,000+ sq ft)
TPO: $8.00 per sq ft $42,000 to $60,000 $160,000 to $320,000 $800,000 to $1,200,000
EPDM: $8.50 per sq ft $45,000 to $75,000 $170,000 to $340,000 $850,000 to $1,275,000
PVC: $9.50 per sq ft $50,000 to $85,000 $190,000 to $380,000 $950,000 to $1,425,000


Flat roofs typically include insulation as part of the roof system itself.
This is different from pitched roofs, where insulation usually goes under the roof deck. The built-in insulation makes flat roofs more energy efficient compared to pitched roof systems. 

Note: PVC costs significantly more, but it's often the best choice when you need chemical resistance or higher fire ratings.

Pitched Roof Costs by Size

Material Small Buildings
(5,000–7,000 sq ft)
Medium Buildings
(20,000–40,000 sq ft)
Large Buildings
(100,000+ sq ft)
Shingle: $5-6 per sq ft  $25,000 to $42,000 $100,000 to $240,000 $500,000 to $900,000
Metal: $7-8 per sq ft $35,000 to $56,000 $140,000 to $320,000 $700,000 to $1,200,000


For pitched roofs, size doesn't affect price as much.
Whether you have a small building or a large building, shingle and metal prices stay fairly consistent. The material type and installation complexity matter more than square footage.

What Does a Commercial Roofing Estimate Include? 

What Does a Commercial Roofing Estimate Include? 

Standard commercial roofing estimates typically include the cost of materials and labor, equipment rental, and a basic membrane warranty. These form the foundation of most quotes and are essential for understanding your baseline budget.

However, there are several commonly excluded costs that can significantly impact your final price. These may include the tear-off and disposal of the existing roof, permits and inspection fees, and replacement of rusted or damaged decking, which can cost around $11.03 per square foot. 

Upgrades to insulation and additional safety measures for active facilities are also frequently left out of the initial estimate.

To avoid budget surprises, always ask your contractor which of these items are included in the quote and which are billed separately. A transparent estimate helps you plan more accurately and reduces the risk of unexpected charges later in the project.

What Makes a Commercial Roof More Expensive?

What Makes a Commercial Roof More Expensive?

These are the big-ticket items that can add thousands to your roof replacement:

  • Tapered insulation creates a slope on flat roofs so water drains properly instead of pooling, causing leaks.
    • Range: $15,000 to $30,000+
  • Every rooftop unit, vent, or pipe that goes through your roof means more detailed work and increased labor costs.
    • Range: $95 to $135 per roof penetration
  • Taller buildings require more safety equipment and take longer to complete.
    • Range: $0.20-$0.54 per sq ft of roof area
  • Decking that is rusted or damaged will need to be replaced.
    • Cost Range: $11.03 per sq ft of roof area 

Insulation per Building Type

Building Type Insulation Level Cost
Warehouse Basic $2.25 per sq ft
Office Building Superior $5.68 per sq ft
Cold Storage Facilities  Elite $7.42 per sq ft


Installation method:

The two most common commercial roof installation methods are mechanically attached and fully adhered. Mechanically attached systems are faster and more cost-effective, while fully adhered systems offer higher durability and are often required for specific wind ratings or manufacturer warranties. 

  • Mechanically attached
    • Cost Range: $6.50 per sq ft to $9.50 per sq ft
  • Fully adhered
    • Cost Range: $9.50 per sq ft to $14.50 per sq ft

Is a Commercial Roof Warranty Worth the Cost?

Is a Commercial Roof Warranty Worth the Cost?

When budgeting for a commercial flat roof, it’s easy to overlook the warranty and go with the cheapest option—but doing so can leave you exposed to major risks down the line. 

Warranty Type Typical Term Cost Range (per sq ft) Minimum Fee
Standard Material 10 to 20 years  Included with purchase of material None
Registered Membrane 10 to 20 years $0.15 to $0.30 $375 to $1,275
System (Edge-to-Edge or NDL) 20 to 30 years $0.30 to $1.00 $375 to $1,275


Coverage by Warranty Type

  • Standard Material: Covers roofing materials, specifically for any manufacturer's defects, but no labor
  • Registered Membrane: Stronger protection that often includes leak coverage and limited labor, but only for the membrane layer
  • System (Edge-to-Edge or NDL): Covers the entire roof system, including flashings and metal trim

Why edge-to-edge matters: Most roof failures start at the edges and corners, not in the middle of the roof. If you only have a membrane warranty and your edge metal fails, it will not be covered. 

What is the Value Engineering Process for Roofing?

What is the Value Engineering Process for Roofing?

When costs exceed your budget, contractors may offer to value engineer your project by:

  • Downgrading from a 30-year to a 20-year warranty
  • Removing tapered insulation
  • Reducing material thickness or quantity

Value engineering helps with budgeting but represents a trade-off in performance and longevity.

Is Roof Maintenance Worth It? 

Is Roof Maintenance Worth It? 

Commercial roofs should be inspected and maintained twice yearly at approximately $0.05 per sq ft annually for medium-sized roofs.

What maintenance can do for you:

  • Add 10 to 20+ years of roof life
  • Prevent warranty-voiding neglect
  • Catch small problems before they become expensive disasters
  • Keep your building dry and operational

Think of roof maintenance like oil changes for a delivery truck. Skip the maintenance, and you'll be replacing the whole thing much sooner than you should. Stay on top of it, and your roof can last decades longer than expected.

What's included in maintenance:

  • Clearing drains and gutters
  • Checking and repairing small membrane issues
  • Inspecting and maintaining flashings and seals
  • Documenting roof condition for warranty purposes 

What Should I Look for in a Roofing Estimate? 

What Should I Look for in a Roofing Estimate? 

The biggest red flag: No manufacturer involvement 

Good contractors get the manufacturer involved from day one. They create detailed specs, do inspections, and provide final sign-off on the completed work.

Why this matters: Manufacturers don't get paid unless the contractor buys their materials. So when a manufacturer spends time creating specs and doing inspections for free, it shows they believe in both the contractor and the project.

Other warning signs:

  • Warranties that only cover the membrane, not the details and flashings
  • No mention of the manufacturer's final inspection
  • Vague descriptions of fastener systems
  • Won't explain the difference between mechanically attached and fully adhered systems
  • Prices that seem too good to be true (they usually are)

Five Questions You Should Ask:

  • "Are you tearing off the existing roof or going over it?"
  • "What happens if you find deck damage?"
  • "Is tear-off included in this price?"
  • "How long will this roof last?"
  • "What about gutters and drainage?"
