Wilmington Roof Pros provides professional chimney & wall flashing in Wilmington, DE for residential and commercial properties across New Castle County. 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.
Roof cement is a temporary material that has spent decades being sold as a permanent one. It is opaque, so from the ground it looks exactly like a completed repair, it lasts two or three winters, and every single reapplication makes the eventual proper fix more expensive than the last one, because somebody now has to chisel all of it back off the masonry before real work can start.
Done correctly, a chimney carries four separate pieces of metal, and all four have to be there. Step flashing woven into every shingle course up both sides. An apron across the front. A saddle or cricket behind it if the chimney measures wider than thirty inches. And counterflashing let into a raked mortar joint, sealed, and lapped over the tops of everything underneath it. Four pieces, no substitutes.
The cricket is the piece that gets left out of most bids. A wide masonry chimney sitting on the up-slope side of a roof holds snow, leaves and grit against its back wall all winter long, and without a framed cricket diverting water around both sides, that back joint is going to leak eventually no matter how good the step flashing beside it is.
Wall flashing follows exactly the same logic. Where a roof dies into a sidewall, we run step flashing up behind the siding and finish with a kickout diverter at the bottom so water leaves at the gutter rather than running down inside the wall. Missing kickouts are why so much of the rot we find around here is inside a wall instead of on a roof.
This is skilled, unglamorous work that gets quoted far too casually and priced as an afterthought. Ask any bidder to describe the four pieces above without looking anything up first, and then ask which state the company files its business license in. Both answers tell you something genuinely useful about who you are about to hire, and neither one costs you anything to obtain.
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 chimney & wall flashing
The difference between chimney & wall flashing that lasts and chimney & wall flashing 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.
