Kansas City MO Premium Roofing provides professional chimney flashing in Kansas City, MO for residential and commercial properties across Kansas City and the Northland. Before we quote flashing on an older Kansas City house, we ask a question most roofers skip. Is this chimney still doing anything. On a great many of these houses the honest answer is no, and that changes the whole recommendation.
The prewar stock here was built around coal, then converted to gas, then reworked again when furnaces moved to sealed combustion and vented out a sidewall. What frequently survives all of that is a masonry stack that no appliance uses, still standing through the roof, still collecting water, still needing flashing, and still costing money every time the roof gets replaced.
So the cheapest correct answer is often removal rather than repair. Drop the stack to below roof level, frame and sheathe across the hole, and the leak is finished rather than managed once every fifteen years. It also deletes the most demanding detail on the roof, removes a masonry maintenance liability, and usually costs less than rebuilding a crown and reflashing properly.
The catch is that decking over a removed chimney is decking, and a stack of any size puts you past thirty-two square feet immediately. That means a permit, and if any framing is involved the city wants a scope and a Residential Contractor license behind it. We tell people that up front, because it turns a same-week job into a filed one and the schedule has to reflect it.
Verify it is genuinely abandoned before anybody swings anything, though. Water heaters in particular are still vented into masonry on plenty of these houses, and a hot water tank orphaned in a chimney that no longer has a furnace drawing with it is its own separate problem. That is a call for a mechanical contractor to make in writing, not a judgment anybody should be making from up on the roof with a flashlight.
Where the chimney stays, flashing means metal in two independent layers and never sealant. Step pieces go in with the courses on either side, each one tucked beneath the shingle above it and bent up hard against the brick. Then counterflashing, cut into a mortar joint and hanging over those steps, so roof movement and masonry settlement never tear each other's seal. Stacks much wider than thirty inches get a framed saddle behind them.
Our licensed and insured team brings the right materials and equipment to every job — one-by-six board sheathing laid with wood-shingle gaps, half-inch plywood overlay screwed across original boards, ring-shank roofing nails landing in solid wood every course, rough-sawn rafters at spacing that never repeats, cut nails withdrawing from ninety-year-old yellow pine, self-adhered ice barrier bonded to a continuous substrate — and backs the work with a written workmanship warranty. We serve Kansas City and nearby communities including Liberty, Gladstone, Excelsior Springs, Smithville.

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 one-by-six board sheathing laid with wood-shingle gaps, half-inch plywood overlay screwed across original boards, ring-shank roofing nails landing in solid wood every course, rough-sawn rafters at spacing that never repeats, 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 Kansas City 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 Kansas City and the Northland means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Kansas City Chooses Kansas City MO Premium Roofing
- ✓We put a square-foot decking number on the estimate. It is the figure that decides your permit, your price and half your arguments, and it is missing from nearly every other quote you will collect in this city.
- ✓We go in the attic before we go on the roof. On a prewar Kansas City house the entire question is what the covering is nailed to, and there is no answer to that from a ladder, a drone or a photograph you emailed us.
- ✓We will tell you when your job needs no permit. Under the city's threshold plenty of roofing here is lawfully unpermitted, and pretending otherwise to look careful would just be theater you paid for.
- ✓We decline standing seam over original board sheathing. The clips need continuous wood and honest fastener withdrawal, and ninety-year-old boards at irregular spacing supply neither one reliably.
The standards behind chimney flashing
Quality here is not a matter of opinion — it is written down. The chimney flashing work we do in Kansas City 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.
Every chimney flashing project in Kansas City gets the same attention, whether it is a single room or a full commercial job. We show up on schedule, keep the site clean, and stand behind the work — the estimate is free and there is no pressure.
