Chimney Flashing Repair in Greensboro, NC

Your chimney is one of the most vulnerable points on your entire roof. Where masonry meets shingles, water is constantly looking for a way in — and the only thing standing between your home and a slow, expensive leak is the flashing. When that flashing fails, the damage rarely announces itself until it's already spread into your ceilings, walls, and framing. At Arthur's Roofing, we've spent over 30 years repairing and rebuilding chimney flashing across the Triad, and we know exactly where these systems break down and how to make them watertight again.

What Is Chimney Flashing and Why It Matters

Chimney flashing is the layered metal system that seals the joint between your chimney and your roof deck. A properly installed system isn't a single piece of metal — it's an assembly. Step flashing is woven into each course of shingles along the sides of the chimney. Base or apron flashing protects the front, where the chimney faces downslope. Counter flashing (also called cap flashing) is set into a cut groove in the mortar joints and folds down over the step flashing to shed water away from the seam. Behind the chimney, a cricket or saddle diverts water around the masonry instead of letting it pool against the back wall.

When all of these pieces work together, water sheds cleanly off your roof and away from the chimney. When even one element is corroded, improperly lapped, or sealed with nothing but caulk, water finds the gap. Because the chimney penetrates the roof at a high-traffic drainage point, a small flashing failure here causes disproportionate damage compared to almost anywhere else on the roof.

Signs You Need Chimney Flashing Repair

Most homeowners don't think about flashing until they see a stain. Here's what tells us — and should tell you — that your flashing needs attention:

  • Water stains on ceilings or walls near the chimney, especially on the upper floor or in the attic.
  • Rusted, lifted, or separated metal visible where the chimney meets the roof.
  • Cracked or crumbling mortar joints, which can pull counter flashing loose or open the reglet where it's seated.
  • Peeling paint or damp drywall in rooms adjacent to the chimney chase.
  • White efflorescence or staining on the brick — a sign moisture is wicking through the masonry.
  • A "quick fix" of tar or caulk slathered over the flashing by a previous contractor. Roofing cement is not a permanent seal; it dries, cracks, and fails within a few seasons.
  • Daylight or drafts visible around the chimney from inside the attic.

If you're seeing any of these, don't wait for the next hard rain. Trapped moisture rots roof decking and framing, invites mold, and turns a modest flashing repair into a structural project.

Our Chimney Flashing Repair Process

We approach every chimney the same disciplined way, whether it's a straightforward reseal or a full rebuild.

1. Thorough Inspection. We start on the roof and in the attic. We identify exactly where water is entering, assess the condition of every flashing component, and check the surrounding shingles, decking, and mortar for hidden damage. You get an honest diagnosis — not a scare tactic.

2. Removing the Failed Flashing. We carefully lift the surrounding shingles and remove corroded or improperly installed flashing. This is where cutting corners shows: we don't seal over old failures, we take them out.

3. Installing New Step and Base Flashing. We install fresh, properly lapped step flashing woven into each shingle course, along with new apron flashing at the front. We use durable, corrosion-resistant metal sized correctly for your roof pitch.

4. Setting True Counter Flashing. Rather than relying on surface caulk, we cut a clean reglet into the mortar joint, seat the counter flashing into it, and lock it with masonry-grade sealant. This is the detail that separates a repair that lasts decades from one that fails in a year.

5. Adding a Cricket When Needed. On wider chimneys, we build a properly pitched cricket behind the stack to divert water. It's a step many contractors skip — and a common reason back-of-chimney leaks keep coming back.

6. Sealing, Finishing, and Verifying. We reintegrate the shingles, finish all seams with the right sealant in the right places, and water-test the repair. We clean up completely and walk you through exactly what we did.
