CHIMNEY REFLASHING SERVICES
Chimney flashing is one of the most common failure points on a roof. Our chimney reflashing services focus on rebuilding proper step and counter flashing systems that manage water correctly and perform in New England conditions.
Why C.M.L. Is the Best Chimney Reflashing Company in ME & NH
Chimney leaks are tricky because the “problem” often isn’t the chimney. Instead, it’s the roof-to-chimney transition where water sneaks in through tired flashing, failed sealant, or missing step flashing. At CML Roofing & General Contracting, we focus on accurate diagnosis, clean waterproofing details, and repairs that hold up through Southern Maine and New Hampshire winters, not quick patches that fail after the next storm.

Our 5-Star Chimney Reflashing Options
Chimney leaks are one of the most common “mystery water” problems in New England because moisture can travel along framing before it shows up as a ceiling stain. Our chimney reflashing services in Southern Maine and New Hampshire are tailored to your roof type, chimney condition, and exposure to wind-driven rain, snow, and freeze-thaw movement.

We rebuild step flashing at chimney-to-roof transitions so water sheds properly and stays out.
Counterflashing Repair / Rebuild
We repair or rebuild counterflashing to seal chimney joints and prevent water intrusion behind metal.
Leak Diagnosis at Chimney Transitions

Common Problems We Fix With Chimney Reflashing Services
Chimney leaks rarely come from one obvious spot. Most start at failed flashing details where the roof meets the chimney, allowing water to enter, travel along framing, and spread into insulation, decking, and interior finishes. Our chimney reflashing services focus on correcting these failure points at the source so the repair actually holds.
Common chimney flashing problems we fix include:
- Failed or improperly installed step flashing at the chimney-to-roof transition
- Loose, missing, or deteriorated counterflashing allowing water behind the system
- Cracked or separated sealant that no longer protects critical flashing joints
- Rusted or aging metal flashing that has lost its ability to shed water properly
- Shingle and roof surface breakdown surrounding the chimney area
- Water intrusion caused by poor water-shedding design around wider chimneys
- Ice dam-related leakage at chimney edges during freeze-thaw cycles
- Hidden moisture intrusion affecting decking, rafters, and attic insulation near the chimney
- Recurring leaks from past patch repairs that never addressed the root cause
- Improperly integrated flashing with siding, trim, or chimney structure
- Soft or rotting roof decking at the chimney intersection
- Water tracking along framing that shows up away from the actual entry point
In Southern Maine and New Hampshire, heavy snow loads, coastal rain, and freeze-thaw movement put constant stress on chimney flashing systems. Our approach focuses on rebuilding these details correctly so water is directed away from the roofline, not into it.
Chimney Reflashing Built for New England Homes
Chimney leaks in Southern Maine and New Hampshire are often caused by the roof to masonry transition, not the shingles alone. Portland, Maine averages about 68.7 inches of snow per year, and Concord, New Hampshire averages about 67.7 inches, which means chimney flashing has to handle heavy snow, ice buildup, meltwater, and repeated freeze thaw movement.
Wind driven rain, coastal moisture, and seasonal temperature swings can also break down old sealant, loosen metal flashing, and open gaps around the chimney. That is why proper reflashing matters. We install step flashing with the shingle courses, cut and secure counterflashing into the chimney, add ice and water protection where needed, and use crickets when the chimney size or roof slope requires better water diversion.
The goal is to stop water at the source and build a chimney flashing system made for New England weather.
Specialized Tools, Materials & Trained Crews for Chimney Reflashing
Chimney reflashing is precision work where small details determine long-term performance. At CML Roofing & General Contracting, our crews are trained to rebuild chimney flashing systems correctly using professional-grade tools and materials designed for New England conditions.
We install properly sized step flashing integrated with shingle courses, custom-fit counterflashing secured to the chimney, and use high-performance sealants only where they belong. When needed, we incorporate water-diversion details like crickets to reduce pressure on the upslope side and prevent repeat leaks.
Safety and property protection are built into every job, with proper harness systems, controlled staging, and care taken around siding, gutters, and landscaping. Every project includes in-process quality checks and photo documentation to confirm that flashing, fastening, and water flow are handled correctly.

How Much Do Chimney Reflashing Services Cost in Southern Maine & New Hampshire?
Chimney reflashing cost depends on how the chimney is built, how the roof ties into it, and what we find once we open up the transition points. In Southern Maine and New Hampshire, steep pitches, tall chimneys, and repeated freeze-thaw movement can turn a “small leak” into a bigger repair if the surrounding decking or trim has started to rot.
On average:
- Minor chimney flashing repairs often start around $400–$900
- Full chimney reflashing (most common) typically ranges $1,000–$2,500
- Complex reflashing + repairs (crickets, steep access, hidden rot) can range $2,500–$5,000+
These ranges are meant to help you plan, not to quote your home. The only accurate way to price chimney reflashing services is an on-site inspection, because roof access, chimney condition, and hidden water damage can’t be confirmed from the ground.
Factors That Affect Chimney Reflashing Cost
- Severity of the leak and how long it’s been active
- Roof pitch/height and access (staging, safety setup, time on roof)
- Flashing scope (step flashing, counterflashing, apron/backpan, chimney saddle/cricket)
- Chimney condition (mortar joints, crown issues, siding/brick interface)
- Hidden rot or water damage in decking, framing, or chimney surround
- Number of sides/rooflines tying into the chimney (valleys, dormers, complex layouts)
- Material matching and component availability (especially on older roofs)
- Seasonality and weather windows (winter leaks, storm response, scheduling)
- Local requirements that affect how the detail must be rebuilt
Online averages are a rough starting point as chimney leaks are detail-driven, and the real scope is often only visible once we inspect the flashing system up close. A professional inspection is the best way to confirm the cause, avoid repeat repairs, and get honest pricing for a lasting fix.
HOW TO TELL IF YOUR ROOF NEEDS ATTENTION:
Chimney leaks rarely start as a dramatic “water pouring in” moment. More often, water sneaks in at the flashing line then spreads into the roof deck, attic insulation, and interior ceilings before you realize what’s happening. In New England, freeze-thaw movement and wind-driven rain can turn a small flashing gap into fast, expensive damage.
Signs it’s time to call now include:
- You have an active leak near the chimney during rain or snowmelt
- Water stains on ceilings/walls around the fireplace or chimney chase
- Dripping, damp wood, or dark staining visible in the attic near the chimney
- Musty odors in the attic or upper rooms (early moisture/mold warning)
- Bubbling paint, soft drywall, or peeling plaster near the chimney area
- Flashing looks lifted, rusted, cracked, or patched repeatedly with sealant
- Shingles or roof material around the chimney look warped, loose, or deteriorated
- You’re seeing mortar/crown deterioration that may be letting water run behind the flashing
- A recent storm or heavy wind caused sudden leaking at the chimney line
If any of these sound familiar, schedule an inspection right away! Chimney flashing leaks can soak insulation, rot roof decking, and lead to interior repairs if they’re left to “wait and see.” If you have active leaking, call now so we can help prevent the damage from spreading.

CHIMNEY REFLASHING FAQ'S
Chimney reflashing typically includes inspecting the chimney-to-roof transition, removing failed flashing/sealant as needed, and rebuilding the water-management details so water sheds properly. This may involve step flashing, counterflashing, ice-and-water protection in vulnerable areas, and new sealing where appropriate. We’ll confirm what your roof system needs during a photo-documented inspection.
If you have active water coming in around your chimney or another emergency, this falls under our emergency roofing services, which we are happy to provide. We can often prioritize an evaluation to help stabilize the situation and prevent further interior damage. Depending on conditions, we may recommend a short term solution first, followed by permanent chimney reflashing when it can be completed safely and correctly.
A properly installed chimney reflashing system should hold up for years, but longevity depends on roof age, chimney condition, exposure, and installation quality. In Southern Maine and New Hampshire, freeze-thaw cycles and wind-driven rain can punish weak details fast. Our goal is to build a tight transition that sheds water reliably through storms and winter conditions.
Yes. We use photo documentation so you can see what we’re seeing, especially at areas that are hard to view from the ground.

Most chimney reflashing projects don’t require a permit, but requirements can vary by town and by scope, especially if the work expands into structural repairs or larger roof sections. If permits or inspections are required for your situation, we’ll help you understand what applies and keep the process straightforward.
We stand behind our workmanship with warranty-backed service specific to the scope performed.
