Chimney Flashing Repair in Stroudsburg, PA

If water is showing up near your fireplace, the fireplace is rarely the problem. In most of the leaks we open up around Stroudsburg, the culprit is the flashing — the metal that seals the joint where the chimney passes through the roof. We repair and completely replace chimney flashing across Stroudsburg, East Stroudsburg and the Poconos, from one failed corner to a full tear-out and rebuild of the entire assembly. Free inspection, and the price in writing before we start: (570) 426-3505.

About Our Chimney Flashing Repair Services in Stroudsburg, PA

Chimney flashing is not one piece of metal. It is a system: step flashing woven into each shingle course along the sides, counter-flashing set into the mortar joints, an apron at the front, and a cricket or back-pan behind the chimney to divert water around it. A leak can start at any one of those, which is why smearing sealant over the top so often fails by the next thaw.

We handle the full range, because the right fix depends on what we find:

Targeted repair — resealing counter-flashing, replacing a corroded apron, or re-bedding counter-flashing into a fresh mortar reglet.
Complete flashing replacement — stripping the old assembly out entirely, replacing step and counter-flashing, and shingling it back in properly.
Cricket installation — for wide chimneys on the upslope side, where snow and debris pile against the back wall with nothing to move water around it.
Roof work the leak uncovers — rotted decking, ruined underlayment or damaged shingles around the chase, handled as part of roof repair in Stroudsburg.

In the Poconos this work is seasonal in a way it is not further south. Freeze-thaw cycling is what kills flashing here: water works into a hairline gap in a mortar joint, freezes, widens it, and does it again a few dozen times over a winter. Add ice damming at the chimney — snow melting against a warm masonry mass and refreezing at the roof edge — and water gets pushed uphill under the shingles, past flashing that would have been fine in a straight rainstorm.

Signs Your Chimney Flashing Is Failing

Water stains on the ceiling or wall near the chimney chase, often a foot or two to the side rather than directly below it.
A damp or musty smell in the attic after a thaw, with no visible drip.
Rust streaks or white mineral staining running down the chimney brick.
Flashing metal that is lifted, wavy, or pulling away from the masonry.
Crumbling mortar where the counter-flashing is set into the joint.
Sealant or roofing tar smeared around the base — a sign someone already tried the cheap fix.
A damp firebox, or a fireplace that smells strongly after rain.

Not sure which of these you are looking at? Call (570) 426-3505 and describe where the stain sits. We can usually tell you over the phone whether it is worth a visit.

Our Chimney Flashing Repair Process in Stroudsburg, PA

1. We start in the attic, not on the roof. Water travels along rafters and decking before it shows on a ceiling, so the wet spot inside is almost never under the entry point. Tracing it uphill from the stain is the only reliable way to find where water actually gets in — and it is how we tell a flashing leak from a cracked crown, a failed chimney cap, or a bad vent boot nearby.

2. We inspect the flashing and the masonry together. Step flashing, counter-flashing, apron, the mortar reglet, and the condition of the brick and crown above it. A flashing repair on a chimney whose crown is shot will leak again, and we would rather tell you that up front than come back twice.

3. You get findings and a written price before any work starts. Photos of what we found, what we recommend, what we would leave alone, and the cost. No pressure and no verbal-only numbers.

4. We repair it so the metal does the work, not the caulk. New step flashing woven course by course, counter-flashing cut into a clean reglet and sealed, shingles replaced around it. On a correct assembly sealant is the last line of defense — never the assembly itself.

5. We water-test and clean up. On any leak we can reproduce, we run water on it before calling the job done, and we haul the debris off your property.

Chimney Flashing Repair Cost in Stroudsburg, PA

Here is the honest version. According to HomeGuide, chimney flashing repair runs roughly $300 to $1,800 nationally, and Angi puts the typical range at $400 to $1,600. Those are market figures, not a quote — but they mean you are not calling around completely blind.

What they cannot tell you is where your chimney lands in that range. These are the things that actually move the number:

How far the water got. Flashing metal is cheap. Replacing soaked decking and insulation around the chase is not.
The condition of the masonry. Counter-flashing has to be bedded into sound mortar. If the joints are crumbling, that has to be dealt with first.
Chimney size and position. A wide chimney on the upslope side may need a cricket built. A small one near the ridge usually does not.
Roof pitch, height and access. A steep third-story chimney takes more setup and more labor hours than a low ranch.
Roof covering. Flashing on slate — common on older homes toward Bangor and the Slate Belt — is specialist work and prices differently than asphalt.
Urgency. An active leak in February is not the same job as planned work in September.

So we will not quote your chimney over the phone, and you should be skeptical of anyone who does — that number is a guess, and guesses get corrected upward once someone is actually on your roof. We inspect for free and then give you a firm written price. Sometimes it comes in well under what people expect: if the leak is one failed corner of counter-flashing and the rest of the assembly is sound, that is what we will tell you, and we will not sell you a full replacement you do not need. Call (570) 426-3505.

Benefits of Professional Chimney Flashing Repair

A chimney leak is one of the cheapest problems to fix early and one of the most expensive to ignore. Water running down the outside of a chase spreads into framing, insulation and drywall, and it does its worst damage where nobody is looking.

You stop the damage at the metal instead of paying for framing. Wet insulation stops insulating and wet sheathing rots — both cost multiples of a flashing repair.
Correct flashing survives our winters. Woven step flashing and properly bedded counter-flashing handle freeze-thaw and ice damming. Surface sealant does not survive a Poconos February.
Documentation for your insurer. Photographed findings matter if a leak turns into an interior damage claim.
No mystery leaks. Diagnosing from the attic means we fix the actual entry point instead of sealing everything nearby and hoping.

Why Choose Allesson Roofing for Chimney Flashing Repair in Stroudsburg

We are based at 312 Sarah Way in East Stroudsburg, so Stroudsburg, East Stroudsburg and most of Monroe County are a short drive rather than a scheduling problem — which is why we can reach an active leak quickly. We are licensed and insured, we work Monday through Saturday from 7am to 7pm, and we handle chimney flashing across the Poconos: from Mount Pocono and the higher-elevation snow belt to the seasonal-home communities around Bushkill and Dingmans Ferry, where a leak that starts in January often is not discovered until spring.

Chimney flashing is not a side job for us. It is the single most common real cause of the leaks we find, which is why we diagnose it from the attic first and why we rebuild assemblies instead of caulking them.

If you have a stain near the chimney, do not wait for the next thaw to see whether it spreads. Call (570) 426-3505 or request a free inspection, and we will tell you exactly what is failing and what it will cost — in writing, before any work begins.

Frequently Asked Questions About Chimney Flashing Repair

Is my leak the flashing or the chimney itself?
Both are common and they look identical from inside. Flashing leaks usually appear after wind-driven rain or a thaw and stain a foot or two off the chase. A cracked crown or spalling brick tends to leak more steadily and often leaves white mineral staining on the masonry. We check both from the attic before recommending anything.

Can you just seal it instead of replacing the flashing?
Sometimes, and we will say so when it is true — a sound assembly with one failed joint can be re-bedded and sealed. But sealant over a corroded or badly installed assembly is a one-winter fix. If that is what your chimney has, we will tell you rather than take the easy money.

How long does chimney flashing repair take?
Most flashing repairs are a single visit. A full replacement that involves masonry work or decking repair can run to two days. We tell you which one it is after the inspection, not after we start.

Do you repair chimney flashing on slate roofs?
Yes. Slate is common on older homes toward Bangor and Northampton County and has to be handled differently — slate breaks if you walk it wrong, and the flashing details are not the same as asphalt.

Will my homeowners insurance cover a chimney leak?
Insurers generally cover sudden storm damage rather than gradual wear or deferred maintenance. Interior damage from a sudden failure is often covered even when the flashing itself is not. We document our findings with photos so you have what you need to file.

Do you offer free estimates for chimney flashing repair?
Yes. The inspection and the written estimate are free, with no obligation.
