If your roof is leaking, showing signs of age, or has suffered storm damage, it may be time to consider a full replacement. One of the first and most important questions homeowners ask is: “How much will a new roof cost me?”
In Delaware, the cost of a new asphalt shingle roof generally ranges from $8,500 to $15,000, depending on a number of factors such as the size of your home, the type of shingles you choose, and the complexity of the roof itself.
Below, we break down exactly what goes into that cost so you can make an informed decision and plan your budget with confidence.
Shingle Roofing Replacement: How Much Does a New Roof Cost?
When planning for a roof replacement, understanding the average cost in your area is an important first step.
In Delaware, pricing for a new asphalt shingle roof typically falls within a moderate range—but several factors can push the total cost higher or lower. Whether you own a modest single-story home or a larger multi-level property, the overall cost will be shaped by your roof’s size, complexity, and the materials you choose.
Below is a general breakdown to help you get a realistic sense of what a roof replacement might cost in today’s market.
Average Roof Replacement Cost in Delaware
Asphalt shingle roofs remain the most popular and cost-effective option for Delaware homeowners. Here’s what you can expect to pay in 2025:
- Small home (1,200–1,500 sq. ft.): $6,500 – $10,000
- Mid-size home (1,800–2,200 sq. ft.): $8,500 – $13,000
- Large home (2,500+ sq. ft.): $12,000 – $17,000+
What Affects the Cost of a New Roof?
1. Roof Size
Roofing is priced by the square foot—specifically, by “roofing squares,” where one square equals 100 square feet.
Larger homes have more surface area to cover, which means more materials and more labor. On average, you’ll pay between $4 to $6 per square foot for a full asphalt shingle roof replacement, fully installed.
2. Roof Pitch & Complexity
A straightforward roof is quicker and easier to replace than one with:
- Steep slopes (which require extra safety gear and time)
- Multiple levels or intersecting planes
- Architectural features like dormers, valleys, or gables
- Chimneys, skylights, or ventilation systems that require careful flashing
3. Shingle Type & Material Quality
Not all shingles are created equal. The price of your roof will also depend on the style and grade of the materials you choose.
Most common types of asphalt shingles:
- 3-Tab Shingles (least expensive, flat look, shorter lifespan)
- Architectural Shingles (dimensional appearance, longer lifespan, better warranty)
- Designer/Luxury Shingles (premium aesthetics, high durability, often mimic slate or wood shake)

4. Tear-Off & Decking Repairs
Before installing your new shingles, your roofer will remove the old roofing material and inspect the underlying decking.
If your roof has multiple layers or if the wood decking is damaged or rotted, that will need to be replaced, adding to the cost. Expect to pay an additional:
- $1,000–$2,500 for tear-off and disposal
- $70–$100 per sheet if plywood replacement is needed
5. Labor & Installation
Labor costs depend on:
- The size and experience of the roofing crew
- Access to the roof (e.g., limited space, steep driveways)
- Time of year (spring and fall are peak season)

If you’re considering a new roof, the best place to start is hiring an experienced roofing contractor to do a thorough roof inspection or request a re-roofing estimate directly.
Remember that the lowest estimate you get isn’t necessarily the best! Consider multiple estimates, and make sure any potential contractor provides several local client references, serves the area from a permanent location, and presents you with valid licensing and insurance information. Ask to see a copy of the roofer’s proof of insurance.
