Dayton Roof Pros provides professional chimney flashing in Dayton, OH for residential and commercial properties across the Miami Valley. A masonry chimney is the textbook casualty of repeated freezing, and the counterflashing keeping your roof dry sits in the mortar joints that suffer first. Mortar takes on water, the water expands as it freezes, the joint face spalls, and the metal it held drops a quarter inch.
So chimney work in Dayton is masonry work as much as it is roofing work. We tuckpoint the courses that will receive the metal before any flashing goes in, because bedding fresh counterflashing into a joint that is already crumbling produces a repair with a two-year life expectancy, and we would simply be back on the same roof doing it again at your expense. That sequence adds a day and decides between twenty years and two.
The assembly is two separate pieces, always. Base flashing goes in course by course, every piece turned up against the brick, and a separate counterflashing is then saw-cut into a mortar reglet, folded down over it, wedged with lead and sealed along the top edge alone. Surface-mounted metal caulked flat to brick is the single most common failure we open up here, and it does not survive one full Ohio winter.
Chimneys wider than roughly thirty inches get a cricket on the upslope side. Without one, meltwater and snow bank up behind the stack and sit through crossing after crossing, and water standing that long always finds the single lap that was not perfect. Ohio's residential code requires that cricket at that width, and in our experience it is skipped more often than it is built.
We look at the crown and the cap as part of the same visit, because they are part of the same problem. A cracked concrete crown admits water into the chimney's own core, where it freezes inside the stack and pushes the top courses apart from the inside, and no flashing detail on earth compensates for that. A stainless cap over the flue keeps the same water out of the liner.
Copper or lead-coated copper is worth the money on a chimney you can see from the street. It weathers rather than corrodes, it moves without fatiguing, and it outlives the roof around it comfortably. Where a chimney is no longer used for anything, we will price removing it below the roof line and framing and sheathing over the opening. That is frequently the cheapest permanent answer available and almost nobody offers it.
Our licensed and insured team brings the right materials and equipment to every job — cold-flexible SBS-modified shingle mats, self-adhering underlayment turned up behind the sidewall siding, lead wedges holding counterflashing in a repointed joint, hemmed 26-gauge valley metal bedded on membrane, lead-sleeve pipe boots in place of bare neoprene collars, kickout diverters where a roof dies into a sidewall — and backs the work with a written workmanship warranty. We serve Dayton and nearby communities including Kettering, Beavercreek, Huber Heights, Fairborn.

Materials, equipment and how we do chimney flashing
The difference between chimney flashing that lasts and chimney flashing that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with cold-flexible SBS-modified shingle mats, self-adhering underlayment turned up behind the sidewall siding, lead wedges holding counterflashing in a repointed joint, hemmed 26-gauge valley metal bedded on membrane, 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 Dayton 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 the Miami Valley means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Dayton Chooses Dayton Roof Pros
- ✓We price the deck before we price the shingles, because in a climate that crosses freezing this often the sheathing is what decides the job
- ✓Every proposal names the shingle line, underlayment, flashing metal and gauge, fastening pattern and ventilation plan, so two bids can actually be compared
- ✓We will tell you a roof has six good years left and put that in writing, rather than quoting a replacement you do not need yet
- ✓Chimneys get tuckpointed before any counterflashing goes into the joint, because bedding new metal in crumbling mortar is a two-year repair
The standards behind chimney flashing
Quality here is not a matter of opinion — it is written down. The chimney flashing work we do in Dayton 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.
