If you’re a homeowner in Philadelphia, Bucks County, Montgomery County, or Delaware County, one of the first questions you’ll ask before starting a roofing project is: How much does a new roof cost?
The answer depends on roof size, material type, and the condition of your existing roof—but below is a clear, local breakdown to help you plan with confidence.
⸻
What Is a Roofing Square?
Roofing is priced by the square, not by the square foot.
👉
1 roofing square = 100 square feet (100 ft²)
So, a 1,800 sq. ft. roof equals 18 squares. This measurement helps contractors provide accurate, transparent pricing.
⸻
Shingle Roof Costs in Philadelphia
Asphalt shingles are the most common roofing system for homes throughout Philadelphia and the surrounding suburbs due to durability, curb appeal, and value.
Average cost per square (100 ft²):
• $550 – $750 per square
What affects shingle roof pricing?
• Type of shingles (architectural vs standard)
• Removal and disposal of old roofing materials • Roof pitch and accessibility
• Chimneys, skylights, vents, and flashing
• Exposure to Philadelphia’s wind, snow, and ice
Example:
A 20-square shingle roof typically ranges from $11,000 to $15,000, depending on complexity and material choice.
⸻
Flat Rubber Roof Costs (EPDM)
Flat and low-slope roofs are common on Philadelphia rowhomes, additions, and commercial buildings. EPDM rubber roofing is a popular option due to longevity and performance.
Average cost per square (100 ft²):
• $400 per square
Flat roof pricing often includes:
• Tear-off of existing roofing
• Surface preparation and insulation (if needed)
• EPDM rubber membrane installation
• Proper drainage and edge detailing
When installed correctly, rubber roofing provides long-term protection and excellent value.
⸻
Why Roofing Costs Vary Across Philadelphia & the Suburbs
Roof replacement costs can vary due to:
• City vs suburban property access
• Permit requirements
• Tight rowhome layouts
• Seasonal demand
• Hidden wood damage found during tear-off
That’s why a professional inspection is essential for accurate pricing.
