Where Brick Meets Roof: The Joint That Decides Whether Your Chimney Leaks
Every February, after the third or fourth freeze-thaw cycle, our phone starts ringing about the same leak: water tracking down the inside wall beside the chimney, or a damp ceiling patch that hugs the flue. The shingles usually get accused, but the culprit is almost always the metal collar where brick meets roof. Raleigh Roof Pro has spent 11 years pulling those failed systems apart and rebuilding them, and chimney flashing replacement is the job we hold to the tightest standard, because it is the joint two trades historically got wrong by blaming each other. We work Raleigh first, then the ring around it: west toward Cary and Morrisville, south into Garner and Apex, north up to Wake Forest, east out to Knightdale.
Two Materials Moving Against Each Other
Brick and wood keep separate schedules. The deck expands and contracts with every summer and every soak, the chimney settles on its own footing, and the mortar stiffens while the shingles flex. Whatever metal sits between them has to absorb that argument for decades, and most original flashing loses it quietly: a seam opens a sixteenth of an inch, wind-driven rain finds it, and the water travels down inside the masonry until it meets your drywall. By the time the stain shows, the metal has been failing for seasons.
Four Sides, Four Different Jobs
A chimney is not one leak point; it is four. The uphill side takes runoff from the whole field above it, which is why chimneys wider than about thirty inches need a cricket to split that water around the brick. The two sides need step flashing woven into the shingles so sideways rain rides out instead of in. The downhill side needs an apron that sheds water off the roof and away from the brick face, not behind the next course. We build each side for its own job, to the NC Residential Code, and we treat a missing cricket as an unfinished system, not an upgrade.
What Comes Out Before Anything Goes In
The teardown is where chimney jobs are won or lost. Old step flashing gets pulled with the shingle courses it is buried in, the counter flashing comes out of its groove, and every smear of tar and roofing cement gets ground off the brick and deck until both surfaces are clean and true. It is slow, loud, unglamorous work, and skipping it is exactly why “new” flashing jobs leak again in a year. We tarp the gutters, board the flower beds, and bag the debris as we go, because the chimney is usually above somebody’s favorite part of the yard.
Sequencing the Trades That Share the Chimney
A chimney belongs to the roofer, the mason, and sometimes the painter, and the flashing fails when those trades work in the wrong order. We set the sequence: sweep and crown inspection before the metal goes on, masonry repairs while the joint is open, base and step flashing woven as the shingles return, counter flashing folded in last, and sealant only at the fold. When a job needs a mason we do not carry, we schedule ours around yours and keep the chimney weather-tight between visits, so nobody’s calendar leaves your house exposed.
One Crew Owns the Whole Joint
The reason chimney flashing fails so often is not the metal; it is the handshake. The roofer points at the mason, the mason points at the roofer, and the homeowner pays for a third opinion. Raleigh Roof Pro ends that argument on our jobs: one crew owns the joint from teardown to final seal, forms its own flashing on its own brake, and answers for every side of the brick. If something we built ever performs badly, there is exactly one company to call, and it is the one already in your file.
The care shows up in the details too. Gutters get covered, shrubs get boarded, the ground gets tarped, and a magnet sweep closes every day. Brick that has stood for sixty years deserves a lighter hand than a demo crew, so we cut shallow, fold once, and never let a grinder kiss the face of a brick that will show from the street.
The Work, in the Order We Do It
Teardown to clean brick and sound deck. New ice and water shield up the uphill side. Step flashing woven in as the shingle courses return. A cricket built or rebuilt where the width demands one. Counter flashing folded into a fresh cut groove and dressed tight to the brick. Apron and side seams sealed at the fold only. Final water test from the top, photos of every stage, and a walkthrough at the ladder before we load the truck.
- Old metal, tar, and cement stripped completely to bare brick and true deck
- Step flashing woven course by course, never face-nailed over shingles
- Counter flashing folded into a fresh groove and sealed at the fold only
- Cricket built or rebuilt on wide chimneys so uphill water splits around the brick
Reading the Stain Before We Climb
The stain’s location tells us which side failed before the ladder leaves the truck. Water on the ceiling downhill of the chimney usually means a broken apron or lifted side flashing. A stain on the wall beside the flue, or damp mortar inside the attic, points uphill, at runoff getting behind the counter flashing or a missing cricket. We confirm the read on the roof, then price the actual failed sides instead of replacing metal that was still doing its job.
When the Chimney Itself Is the Problem
Sometimes the flashing is honest and the masonry is not: a crown cracked into a map, spalled brick wicking water, a missing cap letting rain pour straight down the flue liner. New metal over a sick chimney is a donation, not a repair. We flag the masonry with photos, explain what the City of Raleigh expects on historic properties when that applies, and sequence the masonry work so the chimney closes up dry in one coordinated pass.
Pricing a Chimney the Honest Way
Chimney pricing follows the brick, not the house: how many sides need work, whether the old tar has to be ground out, whether a cricket needs building, and what the roof pitch allows us to stand on safely. The on-site look costs nothing, and the number we hand you is broken out by side and by component, so trimming a line later is a decision you make with eyes open. Copper, painted aluminum, or galvanized: we price the metal your house actually needs. If the chimney leak sits inside a wider roof problem, the related roof repair is quoted in the same visit.
The Questions We Answer on Every Chimney Quote
The crown and the flashing fail in different signatures. A cracked crown usually sends water down inside the masonry, so you see damp mortar joints in the attic or a stain hugging the flue. Flashing failure shows up on the ceiling below the roof line, or on the wall where brick meets the house side. We confirm which one you have with an attic read and a roof check, and we price only the side of the problem that is real.
Almost never, and we explain why on site. Old step flashing is buried in shingle courses that have to come up anyway, and once it is bent out it will not lie true again. Counter flashing that has rusted or been tarred over has lost its fold. Reusing tired metal to save an hour is how a replacement inherits a leak, so new metal goes in on all four sides, formed to your chimney's exact dimensions.
Your call, and we show you samples against the brick before anything is cut. Painted aluminum can match trim or brick tone, galvanized weathers to a quiet gray, and copper goes from bright penny to a deep brown that suits older Raleigh brick beautifully. On historic homes we follow the neighborhood's guidelines on finish, so the chimney sheds water like new and still looks like it has always been there.
We replace flashing year-round, because a leaking chimney in January will not wait for April. Cold weather changes the sequence: sealants need above-freezing cure windows, so we plan folds and seals around the warm hours and keep the joint tarped and dry between stages. What we will not do is cut open a chimney ahead of a freeze with no dry close, so winter jobs get tighter daily scheduling.
They get protected before the first shingle lifts. Gutters are covered so tar chunks and nail scatter never reach the downspouts, shrubs and beds get boarded or tarped, and the ground crew bags debris as it comes down instead of raking it out of the mulch at five o'clock. A magnet sweep closes every day. The chimney gets fixed; the yard you planted stays yours.
Usually not on its own. Carriers treat worn flashing as maintenance, the same as worn shingles. The exception is sudden damage: if a named storm lifts the apron or a fallen limb tears the counter flashing, that event-driven damage can be claimable, and we document it with dated photos and a written cause report so your carrier can judge it fairly. Wear plus time is a homeowner item, and we price it accordingly.
