Wilmington Roof Pros provides professional commercial & multi-tenant roofing in Wilmington, DE for residential and commercial properties across New Castle County. 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.
Two things follow directly from that. A nonresident bidder has to file a surety bond worth 6% of the contract price with the Division of Revenue before construction begins on site, not at closeout. And the requirement aggregates rather than resetting with each job: two or more contracts totaling $20,000 inside a single calendar year trigger the bond exactly as one large contract would.
It reaches subcontractors as well, which owners and managers routinely miss. Section 375 names the subcontractor right alongside the contractor, so a Delaware general contractor carrying an out-of-state roofing sub has not solved the problem simply by being local itself. On a tenant-occupied building that is worth confirming in writing before anybody mobilizes equipment or sets a crane in the parking lot. We ask our own subs for it and we expect an owner to ask us.
The roofing side of our commercial work: sixty-mil fully adhered TPO and EPDM, self-adhered modified bitumen wherever open flame is unacceptable, tapered polyisocyanurate cut to real measured drainage rather than to a generic spec sheet, edge metal detailed to the wind zone, and walkway pad routed to every rooftop unit a mechanical contractor is ever going to need to reach.
For owners and property managers we run scheduled maintenance instead of waiting for the phone. Twice a year, plus after any significant storm, with a photographed condition report per building and a running repair log that follows the asset through ownership changes. Small failures caught in April cost a fraction of the identical failure discovered in January with three inches of snow on the deck and a tenant calling.
We bid tenant-occupied and mixed-use buildings with the disruption written into the scope: staging locations, working hours, where the dumpster sits, how the ground-floor businesses stay open, and who talks to the tenants. That part is usually what decides between two similar prices, and it is usually the thing missing entirely from the cheaper of the two bids. A number without a plan attached to it is not really a number.
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 commercial & multi-tenant roofing
The difference between commercial & multi-tenant roofing that lasts and commercial & multi-tenant roofing 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 commercial & multi-tenant roofing
Quality here is not a matter of opinion — it is written down. The commercial & multi-tenant roofing 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.
