Serving Wilmington, DE & New Castle County
Roof Replacement
When a roof reaches the end of its life, patching it again just delays the inevitable. A full roof replacement in Wilmington, DE protects your home, lowers energy bills, and resets the clock with a fresh manufacturer warranty. We remove the old roof down to the decking, inspect and repair any rotted sheathing, then install your new roof to manufacturer specifications so the warranty stays valid.
Most Wilmington homes use architectural asphalt shingles for the best balance of cost and lifespan, but we also install three-tab and standing-seam metal roofing depending on your budget and goals.
Wilmington is one of the oldest cities in the country, and it shows on the rooftops. Many homes in Quaker Hill, Trinity Vale, and Brandywine Village were originally topped with slate, wood shake, or standing-seam metal, then covered with asphalt as those materials aged out. Tearing off a roof like that often reveals plank decking, two or three old layers, and hidden rot at the eaves — none of which a phone quote will catch.
Out in the post-war suburbs — Bear, Prices Corner, parts of Newark — the original 3-tab asphalt roofs from the building boom are now well past their 20-to-25-year life and reaching replacement age in waves, while newer construction around Middletown runs architectural asphalt. Whatever the era, a proper Wilmington replacement means a full tear-off to the deck, replacing rotted sheathing, correcting attic ventilation, and installing ice-and-water shield at the eaves and valleys — critical here, where winter ice dams and Delaware River nor’easters drive water uphill under the shingles.
Not every roof needs replacing. If the deck is sound and the shingles have life left, targeted roof repair is the smarter spend — you’ll get an honest read either way, not an automatic push toward the biggest job. Not sure where your roof stands? See our signs you need a new roof guide.
In most cases, no. New Castle County does not require a building permit for roof covering replacement as long as the work does not involve repairing or replacing more than 25% of the roof sheathing (decking). That rule comes from the county’s official Work Exempt from Permit document (Dept. of Land Use, revised 1/1/2026), item 1(e). The same rule is in the county code at New Castle County Code §6.03.012(C)(1)(e).
A few important conditions apply even when no permit is required:
City of Wilmington: The City of Wilmington is its own permitting jurisdiction with separate rules from New Castle County. If your property is within Wilmington city limits, check with the City of Wilmington Department of Licenses and Inspections for their specific permit requirements rather than relying on the county’s exemptions.
Most homes are a one-to-two-day job, but Wilmington’s older housing changes the math. Century-old city homes with plank decking, two or three old layers to strip, or rot hidden around chimneys and dormers can run to three days once the surprises surface. That’s why an honest estimate accounts for what might be under the shingles, not just the square footage. The deck is inspected the moment the old roof is off, and you’re told about any added decking or structural work before it’s done — no mid-job surprises added to the bill.

Yes — we work in slate and standing-seam metal, not just asphalt, which matters on Wilmington’s historic homes where the roofline is part of the character and, in some districts, part of the rules. A proper slate or metal repair matches the profile, gauge, and detailing of the original so it looks right and sheds water for decades. Where full slate replacement isn’t in the budget, there are synthetic slate and metal options that carry the look at a lower cost and pass in most historic districts. We’ll walk you through what fits the home and the budget.
In Wilmington, a full roof replacement typically runs $7,000 to $18,000, and where a home lands depends on its size, roof pitch, the shingle type you choose, and what the tear-off uncovers. Architectural asphalt is the most popular choice for the balance of cost and lifespan, while slate or metal restoration on a historic home runs higher. On older city homes, plank decking, multiple old layers, or rot around the chimneys can add to the number — which is why the deck is inspected once the old roof is off and any added cost is confirmed before the work proceeds.

In New Castle County, no permit is required for roof covering replacement as long as no more than 25% of the roof sheathing (decking) needs repair or replacement — per the county's Work Exempt from Permit document (Dept. of Land Use, revised 1/1/2026). Even exempt work must still comply with all applicable construction and zoning codes. Properties in a Historic overlay zoning district require additional review under Section 40.15.161. The City of Wilmington is its own separate permitting jurisdiction — if your home is within Wilmington city limits, check with the City of Wilmington rather than relying on the county exemption.
