Flashing, Chimney & Skylight Repair in Columbia, MO

Columbia sits on rolling glacial-till hills above the Missouri River valley, and that ground moves with every wet spring and freeze-thaw winter. The brick chimneys on the 1890s Foursquare and Craftsman homes in Benton-Stephens and the Old Southwest have been settling for a century, pulling their counter-flashing loose one season at a time. The 1990s subdivision roofs out in Cherry Hill and Rock Bridge carry skylights and furnace vents set into architectural shingle, and the first place those roofs leak is almost never the field of shingles. It is the flashing. Flashing, Chimney & Skylight Repair in Columbia is the work we do most, because it is the number one leak point on a Columbia roof. We bend our own metal in-house, so the flashing fits your chimney, curb, or valley instead of getting close and caulking the gap. If water is already coming in, start with our metal roof leak repair page and we will trace it back to the source.

Why Flashing Fails First on Columbia Roofs

Boone County gets hail and straight-line wind in spring supercells, hot humid summers, and winter ice storms that refreeze overnight. Flashing takes all three. Sealant shrinks in the summer heat, hail dents and opens the laps, and ice works under the edge and lifts it. On the older homes near downtown, the bigger problem is settlement: the brick chimney and the roof plane move at different rates, and the flashing has to allow for that movement instead of fighting it.

• Chimney counter-flashing pulls out of brick mortar joints and lets water run behind it into the attic.
• Skylight curbs on 1990s subdivision roofs crack at the sealant line and stain the ceiling below.
• Step flashing along dormers and sidewalls rusts through where it was nailed instead of woven into the courses.
• Valley metal on low-pitch brick ranches in Grasslands and Lenoir corrodes and traps debris.
• Boots around plumbing vents split after a decade of UV and heat.

Every one of these is a small piece of metal doing a big job, and every one of them is cheaper to fix before the decking under it rots.

Key info: On a 1920s brick Foursquare in North Central, we pulled a chimney that had been sealed with three generations of caulk. The counter-flashing had never been cut into the mortar. We cut a reglet, bent new copper counter-flashing, and the leak stopped without touching a shingle.

Roofing permits and inspection requirements in Columbia and Boone County vary by jurisdiction and scope, so confirm the rules with the City of Columbia building department before work starts.

How We Repair Flashing, Chimneys and Skylights Around Columbia

We do not start by quoting. We start by finding the actual entry point, because water travels along framing and shows up feet from where it got in. On a metal roof we check the panel laps, the fastener rows, and the penetration details together, since a leak at a chimney is often a fastener problem two feet away. Then we fabricate the flashing to the measurement we took on the roof, not to a stock size from a shelf.

1. We inspect the roof, attic, and ceiling stains to trace the water path before we quote anything.
2. We remove the failed flashing, old sealant, and any rotted decking or sheathing underneath.
3. We bend new flashing in-house from galvanized, painted steel, or copper to match your roof and climate exposure.
4. We cut a reglet into brick or mortar where the detail calls for it, so counter-flashing sits in the wall instead of on top of it.
5. We weave step flashing into shingle courses or set it against metal panels with the correct lap and closure.
6. We seal, fasten, and water-test the repair, then photograph the finished detail for your records.

That sequence is why the repair holds through the next ice storm instead of the next rain.

Key info: A stone-coated steel roof on a home outside Rocheport had a skylight curb leaking into the kitchen. The original install had relied on surface caulk at the curb. We fabricated a new curb cap and back-pan flashing in matching steel, set it with proper laps, and the ceiling has stayed dry through two hail seasons.

If the damage runs past the flashing into panels or fasteners, our metal roof repair service covers the rest of the assembly.

Flashing Repair Approaches We Use on Columbia Roofs

Not every leak calls for the same fix. A lifted step flashing on a shingle roof and a rusted valley on a 1950s ranch are different jobs with different materials, and matching the approach to the roof is what keeps the repair from coming back. Here is how we sort them.

We choose the approach on the roof, not over the phone, because the detail that failed tells you what the replacement has to do differently.

Flashing, Chimney & Skylight Repair Cost in Columbia: What to Expect

Most single-detail flashing repairs in Columbia start around $600, and that figure covers the common cases: a vent boot, a small step flashing run, or a skylight reseal with new metal. The price moves with access and height, the material you choose (copper costs more than painted steel), how much rotted decking we find once the old flashing comes off, and whether the chimney needs a reglet cut into brick. Emergency work after a spring hail event or a winter ice storm carries a premium because the schedule fills fast.

Two or three estimates is the right move, and not only on price. Ask each contractor what they found and how they plan to fix it. If one bid says "caulk it" and another says "cut new counter-flashing into the mortar," you are looking at two different jobs, and the cheap one will leak again. Our pricing page lays out the full range so you can compare line by line.

Flashing, Chimney & Skylight Repair Near Me: How to Choose a Contractor Near Columbia

Flashing work is detail work, and the crew you hire matters more than the material. Ask for the license and insurance certificate, and confirm the policy covers roofing work, not just general contracting. Get two or three written estimates that describe the repair, not just a number. Ask for references from jobs in Columbia and the surrounding towns, and call one. If your home is in a historic district or an HOA, check the design review rules before anyone orders metal, because profile and color can be restricted.

Permits for a repair are often not required, but a full re-roof or a structural change usually is, and the rules vary by jurisdiction. We tell you what we know and defer to the local building department for the final word. Reach out through our contact page and we will look at the roof before we quote the fix.
