Introduction

Replacing a roof is one of the largest home improvement expenses most homeowners will face. In the DMV (Washington, D.C., Maryland, Virginia), costs vary widely based on location, materials, labor, and roof complexity. This guide uses data from authoritative local and national sources to show what homeowners really pay, why, and how to budget effectively.

Roof Replacement Costs in Washington, D.C.

Average total cost: around $18,000 for most homes with a range of $10,000 to $25,000.

By roof size:

1,000 sq ft: $5,200–$16,400
1,500 sq ft: $7,800–$24,600
2,000 sq ft: $10,400–$32,800

Material costs (per sq ft):

Asphalt shingles: $3–$11
Metal: $5–$22
Slate: $10–$30
Rubber: $3–$13
Wood: $6–$18

Flat roofs typically run $15–$20 per sq ft, while pitched shingled roofs average $6–$7.20 per sq ft.

Why D.C. runs high:
Labor makes up 40–60% of total cost. Permitting, historic preservation rules, and tight urban job sites increase both time and cost.

Roof Replacement Costs in Maryland

Average total cost: $10,000–$21,000 for a 2,000 sq ft roof, with larger or complex projects reaching $45,000+.

Cost per square foot:

Asphalt shingles: $5.50–$7 installed
Flat roofing: $15–$20 installed
Metal roofing (materials only): $9–$10

A typical 3,000 sq ft architectural shingle roof costs about $21,000. Smaller townhouse roofs may run $8,000–$10,000. Montgomery and Howard counties tend to be at the high end due to larger homes and design complexity.

Roof Replacement Costs in Virginia (Northern VA Focus)

Average total cost: $6,774–$19,409, with most homeowners paying about $8,315.

Cost per square foot:

Asphalt shingles (budget): $4.50–$10
Composite/wood shakes: $7.50–$15
Premium (metal, clay, slate): $12–$45

Size-based estimates:

1,000–1,500 sq ft: $5,000–$7,000
1,500–2,500 sq ft: $7,000–$10,000
2,500+ sq ft: $10,000–$15,000+

Material choice, roof complexity, disposal fees, and accessibility all influence Virginia pricing.

What Drives Roof Replacement Costs

Labor and Permits – Labor is often 40–60% of the total, and D.C. and Maryland permits can be costly.
Materials – Asphalt shingles are the most budget-friendly; slate, metal, and cedar carry higher upfront costs but often last longer .
Structural Repairs – Rotten decking, sagging, or water damage can add thousands to a project.
Roof Complexity – Multiple levels, steep pitches, and skylights require more time and skill.
Timing – Spring and fall are peak seasons; off-peak scheduling can sometimes save money.

Smart Strategies for Homeowners

Get an independent roof inspection – A certified inspection ($600–$1,500) gives you an unbiased condition report before hiring a contractor.
Collect multiple estimates – Aim for at least three bids from reputable contractors, comparing warranties, materials, and timelines.
Understand material lifespan – Higher-cost materials may offer better long-term value.
Budget for contingencies – Include permit fees, debris disposal, and unexpected structural work.
Time your project – Off-season work may be cheaper and more flexible because of material cost and availability.
