Wilmington Roof Pros provides professional slate, tile & specialty roofs in Wilmington, DE for residential and commercial properties across New Castle County. 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.
The first thing to establish on an old slate roof is whether the slate is dead or the metal around it is. Slate that rings when you tap it and does not flake or delaminate along the edges has decades of service left in it. The copper valleys and chimney flashing installed at the same time usually do not, and that tired metal is what is actually leaking into your plaster.
So the right answer here is frequently not a new roof at all, which is not what a canvasser will tell you. It is reflashing: strip the valleys, set new sixteen-ounce copper, reset the surrounding slate on hooks or copper nails, and rebuild the chimney counterflashing into a properly raked mortar joint. That buys decades of service for a fraction of what a full replacement costs.
Individual broken slates get replaced with a slate hook or a copper bib, matched from salvage stock for color, thickness and weathering. We keep salvage on hand because newly quarried slate almost never matches a hundred-year-old roof, and a bright patch of the wrong gray on a front slope is a worse outcome than the crack it was meant to fix.
The warning specific to this market is about who shows up. Slate draws genuine specialty crews from across the Pennsylvania line, which is fine and often welcome, and it also draws people who will nail a slate flat and tar the head lap, which is not. Tarred slate is the most expensive mistake on this entire page, because undoing it breaks more slate than it saved.
So before anyone sets a ladder against a slate roof, take a minute and look them up. The Delaware Department of Labor contractor registry and the Division of Revenue business license search are both public and both free, and between them they tell you which state the company files in. On a hundred-year-old roof you are buying judgment rather than labor, and judgment is worth checking before the ladder goes up.
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 slate, tile & specialty roofs
The difference between slate, tile & specialty roofs that lasts and slate, tile & specialty roofs 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.
