Roof Replacement
A full tear-off on a Wilmington house almost always lands north of $20,000. Here that number is not just a budget line.
Roof Leak Diagnosis & Repair
Most leaks we trace in New Castle County start at a joint somebody else built, not at a hole in the open field of the roof. The usual suspects are a chimney, a wall return, a valley, or a vent boot that got caulked instead of flashed.
Storm Damage Response
The morning after a storm, Wilmington gets a different mix of trucks than most cities its size. Three state lines sit within a short drive of downtown, so crews from Pennsylvania, Maryland and New Jersey can work a New Castle County street all day and still be home for dinner.
Hail Damage Claims & Second Opinions
Northern Delaware is not a hail market the way the plains states are. We do get it, and when we get it we handle the claim properly.
Wind Damage Repair
Wind takes the edges first, every time. On the older Wilmington stock the failure point is almost always the rake and the eave, where the starter course was skipped entirely, laid backwards, or nailed too high to hold anything down in a gust.
Roof Inspections & Contractor Vetting
An inspection here does two jobs. One is the roof itself: what it is made of, how much service life is left, and what fails first.
Asphalt Shingle Roofing
Asphalt covers most of the roofs in New Castle County, and the honest truth is that the shingle itself rarely decides how long the roof lasts. Two houses on the same street with the identical product will fail twenty years apart based on nailing, ventilation and edge detail.
Standing Seam & Metal Roofing
Metal earns its money on the parts of a Wilmington house that were never good candidates for shingles: the low-slope porch roof, the bay window cap, the shed dormer, and the long back addition running at three in twelve where shingles simply are not rated to work. That is where we push metal hardest and where the payback is clearest to see.
Slate, Tile & Specialty Roofs
Wilmington has real slate, and a great deal more of it than most cities this size, because much of the housing stock went up while slate was still the ordinary choice rather than the expensive one. Plenty of what survives is at or past a century old.
Low-Slope & Flat Roof Systems
A lot of the low-slope roofing in this city is not on a commercial building at all. It is the back addition, the porch, the second-floor deck over a kitchen, and the small flat section behind a mansard.
Roof Coatings & Sealants
This page mostly exists to talk you out of something. Roof coatings have a genuine but narrow use, and outside of it they are the most oversold product in this trade.
Attic Ventilation & Intake Air
Ventilation is arithmetic, not opinion. The target is net free vent area of roughly a square foot for every three hundred of attic floor, and half of it belongs low at the eave.
Skylights & Roof Windows
A leaking skylight is usually not a broken skylight. It is a flashing kit nobody bought, or a unit dropped into an old roof and bedded in sealant instead of stepped into the courses.
Seamless Gutters & Downspouts
Gutters do far more work on an older Wilmington house than most people expect. The houses sit close together, the roofs are steep, and the ground slopes toward stone and brick foundations that were built well before anybody in the trade thought seriously about drainage.
Fascia, Soffit & Rake Trim
Fascia and soffit are the edge of the building, and nobody thinks about them. On the older houses across New Castle County they are reliably the first thing to rot, the first thing an inspector writes up, and the very last thing anybody puts in a budget.
Chimney & Wall Flashing
If your ceiling is staining near a chimney, the chimney is almost never the leak. The flashing around it is, and nine times out of ten that flashing turns out to be a thick bead of roof cement smeared over the joint where step flashing was supposed to go.
Emergency Tarping & Temporary Cover
Our rule on emergency work is simple, and in this trade it is unusual. The tarp is its own job, with its own price, its own invoice and no strings attached.
Commercial & Multi-Tenant Roofing
Commercial work in New Castle County is where Delaware's contractor rules stop being background and turn into a line item in the bid package. Nearly every commercial roof clears $20,000, so a bidder's residency status is a live question on essentially every award.
Insurance Claim Support
We document claims. We do not negotiate them for you, because negotiating a claim is adjusting, and in Delaware public adjusting is a separately licensed activity that a roofing contractor does not hold and should never pretend to.
Wilmington Roof Pros is a licensed, insured roofing contractor in Wilmington, Delaware, handling roof replacement, roof repair, roof leak repair, roof inspections and storm damage restoration for houses, twins, apartment buildings and commercial property throughout New Castle County. We work in asphalt shingle, standing seam metal, slate, EPDM, TPO and modified bitumen.
We spend the money on the parts nobody photographs, because those are the parts that decide how long a roof actually lasts here. Six-nail fastening inside the printed nail zone, capped-nail synthetic underlayment, self-adhered membrane at every eave and valley, brand-new step flashing and counterflashing at every wall and chimney, and a measured intake-air calculation before anybody touches a ridge vent.
One thing genuinely sets this market apart, and it is not the weather. Wilmington sits a short drive from Pennsylvania, Maryland and New Jersey, so a real share of the crews working these streets are not Delaware businesses at all. Delaware treats those firms differently under its bonding law, so we print our license and registration numbers on every proposal and tell you exactly how to check them.
What Wilmington Customers Say
Three bids, and this was the only one that came with a license number and a page telling me how to look all three companies up. Two of the others were not registered in Delaware at all. The roof took two days and the plank decking they replaced was itemized before they started.
Somebody knocked after the June storm offering a free tarp if I signed for a whole roof that night. These guys tarped it the next morning, charged me for the tarp, and told me to take a week on the roof decision. I did, and I still hired them.
I had already been quoted a coating for the flat section over the kitchen. They cut a core, showed me soaked insulation in the photo, and refused to coat it. Replaced that section only and left the shingle roof alone. First contractor who ever talked me out of spending money.
Hundred-year-old slate. I expected the usual push to tear it all off. Instead they reflashed the valleys in copper, reset about forty slates from their own salvage, and told me the roof has decades left. Matched so well I cannot find the patches from the street.
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.
- ✓We refuse coating work on wet or delaminated substrate instead of selling it, and we put the refusal in writing with the core photographs.
- ✓Sheathing is priced per sheet and flashing is a separate line from the field, so the number on the last page is the number you actually pay.
About Wilmington Roof Pros in Wilmington, DE
Wilmington Roof Pros is a Delaware roofing contractor working across New Castle County, from Claymont down to Townsend and west to Hockessin and Newark. We do replacement, repair, leak tracing, flashing, gutters and low-slope work on houses and on commercial buildings, and we keep a place of business in this state rather than driving in from another one.
That last part sounds like a small thing and it is not. Delaware draws a hard line between resident and nonresident contractors, with an extra bonding requirement on out-of-state firms above $20,000. In a city this close to three state lines, knowing which side of that line your roofer sits on is genuinely useful, so we put our license and registration numbers on every document we hand you.
When you should not hire us: if your roof is under fifteen years old and leaking in one spot, you need a flashing repair and not a replacement, and we will say so and quote the small number. If your low-slope roof cores wet, we will refuse the coating somebody else offered you. And if you want a designer shingle on an ordinary house because a salesperson said so, we will tell you where that money does more good.
How It Works
- 1
Free Inspection, Slope by Slope
We walk every slope we can stand on safely and use a pole camera for the rest, then go into the attic. You get dated photographs of each slope with anything we flag circled on the image, and that packet is yours whether or not you hire us.
- 2
The Four-Minute Contractor Check
With the estimate we hand you a page listing our Delaware business license number and our Department of Labor contractor registration number, plus the two free state searches that verify them. Run it on us and on every other bid on your table. It takes about four minutes.
- 3
A Written Scope With the Unknowns Priced
Sheathing is priced per sheet, flashing is a separate line from the field, and the ventilation calculation is in the document. Nothing gets renegotiated from your roof at eleven in the morning once the old shingles are already in the dumpster.
- 4
Install, Clean Up, Then Walk It With You
We magnet-sweep the property twice, photograph every completed detail, and walk the finished job with you before the final payment. The workmanship warranty is written, and the photographs go with it so you know what is under the shingles.
Commercial Roofing in Wilmington, DE and Across New Castle County
We roof and maintain office buildings, mixed-use blocks, apartment and condominium buildings, warehouses along the US 13 and I-95 corridors, and retail centers throughout New Castle County. Nearly every commercial roof clears the $20,000 mark where Delaware's nonresident bonding rule applies, and the rule reaches subcontractors as well as the general contractor, so we confirm that status in writing on every project we bid and every sub we carry.

- ✓Delaware business license and Department of Labor registration numbers supplied with every bid package
- ✓Written confirmation of resident or nonresident status for every subcontractor on the job

- ✓Walkway pad routed to every rooftop unit a mechanical contractor has to reach
- ✓Staging, working hours, dumpster location and tenant communication written into the scope
- ✓Infrared and core-cut moisture surveys before any recover or coating is proposed

Frequently Asked Questions
Does Delaware license roofing contractors?
Not as a trade. Delaware licenses electricians, plumbers and HVACR through the Division of Professional Regulation, but there is no state roofing license. What a roofer here must have is a business license from the Division of Revenue and a contractor registration certificate from the Department of Labor, and both are publicly searchable. Anyone advertising a Delaware roofing license is describing something the state does not issue.
What is the nonresident contractor bond, and why does it matter to me?
Under Title 30, Section 375 of the Delaware Code, a contractor that does not regularly keep a place of business in Delaware has to file a surety bond with the Division of Revenue worth 6% of the contract price on any job of $20,000 or more, before construction begins.
It also aggregates: two or more contracts totaling $20,000 in one calendar year trigger it. If the company doing your roof is from out of state and never filed, the remedy the law built for you does not exist.
How do I check a roofing company in Wilmington, DE?
Two free searches. The Division of Revenue business license search at revenue.delaware.gov returns the license number, the activity, the valid dates and the business address, and that address tells you which state they file in. The Department of Labor registry at contractorregistry.delaware.gov shows the contractor registration. If a company appears in neither, call the Department at the number listed on that site before you sign.
Why are so many roofing trucks here from other states?
Geography. Wilmington sits close to the Pennsylvania, Maryland and New Jersey lines, so a crew can work a New Castle County street all day and sleep at home. Plenty of those companies are good. The point is not that out-of-state is bad, it is that the paperwork requirements are different, and you should know which category your contractor falls into before money moves.
How old are the roofs in Wilmington, and does that change the price?
It changes what is under them. The Census Bureau's 2023 five-year estimates put 15,521 of the city's 35,772 housing units at 1939 or earlier, which usually means plank decking rather than plywood. Plank decks are sound but uneven, and some boards will need replacing. That is why we price sheathing per sheet in the written scope instead of discovering it mid-tear-off.
Should I take a free tarp after a storm?
Take the tarp, but pay for it and get an invoice. A free tarp tied to a signed replacement contract is the oldest sales technique in this trade, and it is common here for a reason: the tarp is far below the state's $20,000 bonding threshold and the replacement it leads to is well above it. Our tarps are billed as their own job with no strings, and you can hire somebody else for the roof.
