Columbia MO Roof Pros provides professional chimney flashing in Columbia, MO for residential and commercial properties across Boone County and mid-Missouri. Columbia has a great many brick chimneys that no longer do anything. The furnace was vented out a sidewall two owners back, the fireplace was closed off, and the stack simply stays where it is, penetrating the roof and needing flashing forever for no benefit at all.
On a rental, our first question is whether the chimney is live. If nothing vents through it and nobody burns anything in it, taking it down below the roofline and framing and decking over the opening is often cheaper than rebuilding the flashing properly, and it retires a leak point and a masonry maintenance item permanently. Owners are usually surprised that removal is the cheaper of the two options.
Where the chimney stays, the flashing has to be a two-part assembly. Step flashing woven into the shingle courses at the sides, an apron across the front, a cricket behind anything wider than about thirty inches, and counterflashing let into a cut reglet or a raked mortar joint. Surface-mounted counterflashing sealed to brick is a two-year repair. Sealant on brick has a working life measured in seasons rather than decades.
The masonry comes first in the sequence, not afterwards. Bedding new counterflashing into crumbling mortar means the joint fails and takes the metal with it. Repointing the courses that will receive the metal, and rebuilding a cracked crown, happens before anything is cut in. That ordering surprises people and it is not negotiable here. Doing the metal first means paying for the metal twice within a few years.
The cricket is the detail most often skipped. Without one, the uphill side of a wide chimney collects debris and holds water against the brick through every wet spell, and the brick spalls. Framing and flashing a saddle costs a fraction of rebuilding a face of masonry that has taken ten years of standing water. Spalled brick is a masonry bill, and it is a much larger one.
Interior staining beside a chimney is not always flashing. Condensation inside an unlined flue, and rain entering an open uncapped top, both stain the same stretch of wall. We look at the crown and the cap before selling a flashing job, because rebuilding perfectly sound metal fixes nothing if the water is coming down the inside. A stainless cap with a cross break sheds the rain and keeps the birds out.
Our licensed and insured team brings the right materials and equipment to every job — self-adhered ice barrier turned two feet inside the heated wall line, hemmed 26-gauge drip edge lapped over a gutter apron, hot-dipped galvanized step flashing woven course by course, coil-wrapped fascia over primed and sound sub-fascia, vented soffit panels sized to the existing overhang, six-inch K-style seamless gutter carried on hidden hangers — and backs the work with a written workmanship warranty. We serve Columbia and nearby communities including Ashland, Centralia, Hallsville, Sturgeon.

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 self-adhered ice barrier turned two feet inside the heated wall line, hemmed 26-gauge drip edge lapped over a gutter apron, hot-dipped galvanized step flashing woven course by course, coil-wrapped fascia over primed and sound sub-fascia, 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 Columbia 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 Boone County and mid-Missouri means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Columbia Chooses Columbia MO Roof Pros
- ✓We ask when your certificate of compliance expires before we quote, because the renewal date shapes the schedule more than the weather does
- ✓Every report is written against the property maintenance code sections an inspector actually cites, section by section, rather than as a sales sheet
- ✓A code correction and a storm loss are kept in separate documents, because a violation notice is not a claim and presenting it as one gets it denied
- ✓We will tell you to delete a skylight or take a dead chimney below the roofline instead of selling the replacement, where that ends a repeat finding for good
