Wilmington Roof Pros provides professional roof replacement in Wilmington, DE for residential and commercial properties across New Castle County. A full tear-off on a Wilmington house almost always lands north of $20,000. Here that number is not just a budget line. It is the exact figure Delaware law uses to decide what the company on your driveway has to file before anyone touches the roof.
Under Delaware Code Title 30, Section 375, a nonresident contractor has to post a surety bond with the Division of Revenue worth 6% of the contract price on any job of $20,000 or more. Nonresident means a firm that does not regularly keep a place of business in Delaware. The bond has to be on file before construction begins, and the rule aggregates across two or more contracts in the same calendar year.
We keep our place of business here, so that bond never applies to us. What we do instead is print our Delaware business license number on the proposal and tell you to run it yourself through the state's own search at revenue.delaware.gov. The address that comes back tells you which state the company actually files in, which is the one fact a glossy brochure will never give you.
The technical work on a tear-off in this city is mostly about what the last roof hid. Housing here is genuinely old. The Census Bureau's 2023 five-year estimates put 15,521 of Wilmington's 35,772 housing units at 1939 or earlier, which usually means plank decking under the shingles rather than plywood, with gaps between the boards and a hundred years of nail holes in the same framing.
So we price sheathing by the sheet in writing before the tear-off starts, rather than renegotiating from your roof at eleven in the morning when the old shingles are already in the dumpster. Everything else we do the ordinary way, properly: synthetic underlayment across the field, self-adhered membrane at the eaves and in the valleys, and brand-new step flashing at every wall. We never reuse flashing.
The part nobody tells you is that a fifteen-year-old roof leaking in one spot is a repair, not a replacement, and we will say that on the first visit even though it costs us the bigger ticket and the better week. Ask every bidder for a Delaware business license number and a Department of Labor contractor registration number. A company that files here hands both over without being asked twice.
Our licensed and insured team brings the right materials and equipment to every job — capped-nail synthetic underlayment over plank decking, sixteen-ounce copper valley pans reset on slate hooks, closed-cut valleys laid over W-profile valley metal, kickout diverters at the roof-to-wall gutter return, framed crickets behind masonry chimneys wider than thirty inches, lead vent boots in place of dried-out rubber collars — and backs the work with a written workmanship warranty. We serve Wilmington and nearby communities including Newark, Middletown, Bear, Glasgow.

Materials, equipment and how we do roof replacement
The difference between roof replacement that lasts and roof replacement that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with capped-nail synthetic underlayment over plank decking, sixteen-ounce copper valley pans reset on slate hooks, closed-cut valleys laid over W-profile valley metal, kickout diverters at the roof-to-wall gutter return, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Wilmington job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of roofing work in New Castle County means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Wilmington Chooses Wilmington Roof Pros
- ✓Every proposal carries our Delaware business license number and our Department of Labor contractor registration number, plus the two free state searches that verify them.
- ✓We are a resident contractor under Delaware law, meaning we keep a place of business in this state, so the nonresident surety bond never applies to us. We will tell you plainly when it applies to somebody else's bid.
- ✓We tell you when another bid on your table is from a Pennsylvania, Maryland or New Jersey company. That changes what has to be on file before work starts, not what the roof is worth.
- ✓Tarping is billed and closed as its own job with its own invoice. It is never the deposit on a replacement you have not agreed to.
The standards behind roof replacement
Quality here is not a matter of opinion — it is written down. The roof replacement work we do in Wilmington follows published industry standards: NRCA publishes the Roofing Manual, the industry's reference for details and slope minimums, and Asphalt Roofing Manufacturers Association sets the shingle application and ventilation guidance the warranties reference. If a contractor cannot tell you which standard a detail comes from, that is worth asking about before you sign.
Every roof replacement project in Wilmington gets the same attention, whether it is a single room or a full commercial job. We show up on schedule, keep the site clean, and stand behind the work — the estimate is free and there is no pressure.
