What a new roof costs in Delaware

The average cost to replace a roof in Delaware is about $12,553. This is based on the average roof size (with pitch) in Delaware of 2,402 sqft (24.00 squares) and the area's most common material, Asphalt Shingle, which runs about $5.23 per sqft ($ 523/square).
The roof area behind Delaware's cost estimate is 2,402 square feet, or 24.02 roofing squares. A roofing square is 100 square feet of roof surface, not 100 square feet of indoor living space. That is 98 square feet smaller than a 2,500-square-foot roof. At the asphalt shingle rate shown here, each additional 500 square feet adds about $2,615 to the calculated replacement cost. This helps explain why a smaller roof can come in below the $12,553 statewide estimate even when the contractor's rate is the same. Use your measured roof area, including pitch, rather than your home's listed floor area to compare estimates.
Material choice changes the budget for the same Delaware roof. The asphalt shingle estimate is $12,553 for the roof area used on this page. Metal comes to $27,282, about $14,729 more (117% higher). Designer Shingle comes to $16,822, about $4,269 more (34% higher). These are comparisons of the material estimates listed below, not a promise that every contractor will quote the same difference. Keep the roof area and scope of work the same when comparing materials so a change in size does not look like a change in price.
For a size-based budget in Delaware, a 2,000-square-foot roof at $5.23 per square foot works out to about $10,460 for asphalt shingle. A 3,000-square-foot roof at that same rate works out to $15,690. Both examples use roof surface area and the rate displayed on this page; they are not separate averages for homes of those sizes. Before choosing a roofer, compare written quotes for tear-off, disposal, underlayment, flashing and any decking repairs. Ask which items are included and which would add to the price. The statewide figure is a starting point for budgeting, while the final quote depends on your roof and the work it needs.
Pitch matters as much as size. The average roof slope in Delaware is 6/12 Pitch, or about 26.57 Degrees. A steeper roof has more surface area than the footprint of the home beneath it, and it usually takes longer and costs more to work on. Two homes with identical floor plans can carry noticeably different roof areas if one has a steeper pitch, which is why the measurements behind these estimates include pitch rather than treating every roof as flat.
Location inside Delaware moves the number too. Across the 20 Delaware communities tracked on this page, estimated replacement costs run from about $11,812 in Selbyville, DE to about $13,407 in Bear, DE. Local labor rates, material delivery distances and demand all feed into that spread, so the city figures are estimates built from the same statewide pricing data, not separate surveys. If your town is not listed, the statewide average is the most reliable starting point.
These estimates come from 62,400 roofs measured in Delaware and pricing entered by 190 contractors using the Instant Roofer app, alongside 0 verified homeowner reviews. Because the figures refresh as new measurements and pricing arrive, treat them as a current snapshot rather than a fixed quote. The most accurate number for your home comes from measuring your own roof, which you can do free with the calculator at the top of this page.
