Chimney Flashing Repair in New Canaan, CT
Flashing is the metal that seals the joint where the chimney comes through the roof. When water shows up on a ceiling near the chimney and only in driving rain, this is almost always why.
Leave the building and call from outside — that is an emergency services call, not a service call. A blocked or failed flue is one of the ways carbon monoxide reaches a living space, and headaches that clear when you leave the house point the same way. If you have had a chimney fire — a roaring sound, dense smoke, or debris on the roof — do not light another fire until the flue has been inspected.

Chimney Flashing Repair in New Canaan
Equipment in New Canaan has to cover a wider range than most of the country asks for — hard winter cold at one end and humid stretches in the eighties and nineties at the other. A system sized for the middle of that range disappoints at both ends of it.
About 18% of homes in New Canaan were built before 1940 — old enough to have been built with radiators and no ductwork at all; 45% of them still heat with oil, and oil condensate is acidic enough that those flues deteriorate from the inside where nobody looks. (US Census ACS 2022)
Why the shoreline sees more of this
Wind-driven rain behaves differently from rain falling vertically. It gets under laps, drives up the face of a flashing, and finds gaps that hold perfectly well in ordinary weather. Along the Sound and the southeastern shoreline that is most of the serious rain, which is why flashing failures cluster on the coast.
If it leaks only in storms
That is the signature. A cracked crown leaks in any rain; a flashing gap leaks when the wind drives water at it. Telling the two apart before anyone starts work saves repairing the wrong thing.
Coordinating with a reroof
The best moment to redo chimney flashing is when the roof is off, and the worst outcome is a roofer bedding tiles or shingles over the old flashing to save time. If a reroof is coming, raise the chimney detail before the work starts.
What proper flashing is, and what it is not
Correct flashing is two separate layers. Step flashing is a series of L-shaped pieces woven in with the roof courses as they go up the side of the chimney. Counter-flashing is a second layer let into a groove cut in the mortar joint, folded down over the step flashing so water running down the masonry is thrown clear.
What is very often there instead is roof cement or sealant troweled across the joint. It looks like a repair for a season or two, then it shrinks, cracks and lets water straight in. Any quote that describes the fix as sealing or caulking the joint is describing a patch.
The reglet is the detail that lasts
Counter-flashing has to be cut into the mortar, not stuck to the surface. Surface-mounted metal held with sealant fails when the sealant does, which is a matter of a few years. A reglet cut and the metal wedged and pointed in lasts as long as the roof.
Roof material changes the job
On asphalt shingle this is routine. On slate it is skilled work, because slates have to be lifted and relaid rather than nailed through, and a broken slate becomes the next leak. On cedar shingle the detail again differs. Ask what experience they have with your roof, not just with chimneys.

Chimney Flashing Repair in New Canaan — FAQs
How often should a chimney be inspected?
Annually, whatever it vents — that is the NFPA 211 standard and it covers gas and oil appliances as well as wood. Sweeping frequency is separate and depends on what and how much you burn. An appliance used twice a year still needs the annual look, and those are the ones where neglected faults turn up.
Do we need a chimney liner?
If a camera survey finds cracked tile, washed-out joints or a separated liner, yes. You also need one whenever the flue is the wrong size for the appliance now venting into it, which is the common case after any change of fuel or appliance. A liner is sized from the appliance manufacturer venting tables, not from what happens to fit down the chimney.
What does a Level 2 inspection include?
Everything in a Level 1 visual check, plus a camera survey of the entire flue and an examination of accessible attic, crawl space and basement areas. It is required on a property transfer, on any change of fuel or appliance, and after a chimney fire. A general home inspection does not include it.
Is chimney waterproofing worth doing?
On sound, porous, exposed masonry it genuinely slows the water absorption that destroys brick. On masonry that has already started to flake it is worse than doing nothing, because it traps water behind the damaged face. And it has to be a breathable repellent rather than a film-forming sealant — the film is what causes the damage people then blame on waterproofing.
What qualifications should a New Canaan chimney company have?
Ask for three things and check them: current liability insurance, CSIA certification from the Chimney Safety Institute of America, and whatever license or registration your state requires for the work in question. Ask to see the documents rather than taking the logo on the van as proof. For anything involving gas appliance venting, ask separately who is pulling the permit.
Can you work on a rental or multi-family property in New Canaan?
Yes. Ask for the findings in writing so a landlord or managing agent can act on them. In multi-family buildings the usual complication is the stack itself — one chimney frequently carries flues for several units with different owners, so establishing whose flue is whose comes before anyone quotes work.
How do I know it is the flashing and not the crown?
Timing. Flashing leaks appear with wind-driven rain and often stop in ordinary showers. Crown leaks appear whenever it rains. A hose test from the roof, working upward in sections, settles it.
Can flashing just be sealed?
As a temporary measure before proper work, yes. As the repair, no — sealant over a flashing joint is the single most common failed chimney repair, and it usually hides the actual gap.
