About this service
What Chimney Flashing Repair in Milford, Connecticut Involves
Chimney flashing repair in Milford, Connecticut is the work of resealing or rebuilding the metal that bridges your roof surface and your chimney walls. That metal comes in layers: base flashing woven into the shingles, step flashing up the sides, counter-flashing cut into the masonry, and a cap or apron at the front. When any layer lifts, cracks, or rusts through, rain finds the gap. We remove the failed sections, replace them with new metal, and reset the counter-flashing into fresh mortar so the joint sheds water instead of drinking it.
Most flashing failures we see in Milford start with age, not storms. A 20-year-old roof has been through hundreds of freeze-thaw cycles, and the sealant under the counter-flashing dries out and pulls away from the brick. That is when you get a chimney leak, and it usually shows up as a brown ring on the ceiling or rust streaks on the firebox. Homeowners searching for chimney flashing repair near me Milford CT usually find us after the second or third rain that leaves a bucket on the floor. We stop that cycle.

What's included
What Our Chimney Flashing Repair Includes
Every flashing job we do in Milford includes the same core scope, so you know exactly what you are paying for. If we find rot, a failed crown, or a damaged liner while we are up there, we quote it separately and let you decide. No surprise line items.
✓
Full Leak Inspection
Roof-side and attic-side inspection of the base flashing, step flashing, counter-flashing, and the mortar groove. We use an inspection camera inside the flue and check the roof deck for water staining so we know the full extent of the damage.
✓
Old Flashing Removal
We cut back the shingle courses, pull the rusted step flashing, and grind the old counter-flashing out of its groove. Rotted decking or sheathing gets replaced before anything new goes down. This is the step that separates a real repair from a smear of sealant.
✓
New Metal Installation
New copper or stainless step flashing woven into the shingles, new counter-flashing set into a fresh mortar groove, and a new apron at the front of the chimney. We use flashing tools and fasteners rated for exterior masonry and coastal air.
✓
Sealant and Mortar Work
We pack the counter-flashing groove with refractory mortar and seal the edges with ChimneySaver or Rutland flashing sealant. The joint is built to shed water, not just sit there. This is where most DIY flashing jobs fail.
✓
Water Test and Photos
We hose the chimney from multiple angles and check the attic side for drips before we call the job done. You get before-and-after photos, a written workmanship warranty, and a reminder to have the sealant checked each spring.
How it works
How Our Flashing Repair Process Works
01
Roof and Attic Inspection
We start on the roof and finish in the attic. Up top we check the base flashing, step flashing, and counter-flashing for rust, lifting, and missing fasteners. Inside, we look for water staining on the roof deck and rafters. This takes about 30 minutes and tells us whether you need a repair or a full chimney flashing replacement Milford CT homeowners can count on.
02
Leak Source Confirmation
Flashing is not the only thing that leaks. We run a smoke test kit and a controlled water test to confirm the water is coming in at the flashing and not through a cracked chimney crown or open mortar joints. Confirming the source first keeps you from paying for the wrong repair.
03
Old Material Removal
We cut back the shingles, pull the rusted step flashing, and grind out the old counter-flashing groove with an angle grinder. Any rotted roof decking gets replaced before new metal goes down. This is the messy part, and it usually takes one to two hours.
04
New Flashing Installation
We set new copper or stainless step flashing, weave it into the shingle courses, and seat the counter-flashing into a fresh mortar groove. We use a masonry trowel and refractory mortar to lock it in, then seal the edges with ChimneySaver or Rutland flashing sealant. Every fastener gets covered by the next shingle course.
05
Water Test and Cleanup
We hose the chimney from three angles and watch the attic side for drips. If it is dry, we clean the roof, haul away the old metal, and walk you through photos of the repair. You get a written workmanship warranty and a reminder to re-check the sealant each spring.
Tools & methods
Tools and Methods We Use on Flashing Jobs
Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.
Flashing Tool and Masonry Trowel
Used to bend and seat step flashing and counter-flashing, and to pack fresh mortar into the counter-flashing groove so the metal sits tight against the brick.
Angle Grinder
Cuts the old counter-flashing out of the masonry groove and grinds the joint clean so new mortar and metal bond properly. A clean groove is the difference between a seal and a smear.
Inspection Camera
Lets us see inside the flue and behind the chimney chase without tearing anything apart. We use it to confirm whether water has reached the liner or the insulation.
Smoke Test Kit
Confirms the leak path by tracking smoke and air movement through the chimney. It separates a flashing leak from a crown or mortar joint leak before we quote the repair.
Mortar Mixing Paddle
Mixes refractory mortar and tuckpointing mortar to the right consistency for the counter-flashing groove and any masonry repair that comes up during the job.
ChimneySaver and Rutland Sealants
Exterior-grade flashing sealants that stay flexible through Milford freeze-thaw cycles. We use them on the counter-flashing edges and any exposed fasteners.
Real results
Before and after.
Counter-Flashing Reseal in Woodmont
Before
A 1940s brick chimney in Woodmont had counter-flashing sealant that had dried and pulled away from the brick on all four sides. Every hard rain sent water down the chimney chase and left a brown stain on the ceiling below.
After
We ground out the old sealant and mortar, reset the counter-flashing into a fresh groove, and sealed it with ChimneySaver. A three-angle water test ran dry. The repair took three hours and cost $520.
Full Flashing Replacement in Devon
Before
A Devon home had step flashing rusted through in two places, with water staining the roof deck and a soft spot in the sheathing. The homeowner had already patched it twice with roof cement, which had failed both times.
After
We pulled the shingle courses, replaced the rotted decking, and installed new copper step flashing and counter-flashing. The job took six hours and cost $1,850. Two winters later the attic is still dry.
Coastal Metal Upgrade in Walnut Beach
Before
A Walnut Beach cottage had galvanized flashing that had corroded to the point of flaking apart. Salt air had done the damage, and the chimney leaked into the attic every time the wind blew rain against that side of the house.
After
We replaced the galvanized metal with stainless steel step flashing and copper counter-flashing, then reset the mortar groove. Cost was $1,400, and the chimney has not leaked through two storm seasons.
Problems we solve
Chimney Leaks We Fix in Milford
Most chimney leaks trace back to one of a handful of failures. Here are the ones we see most often on Milford roofs, and what happens if they are left alone.
Ask a pro →↗
Step flashing rusted through at the roof line
We pull the shingle courses back, replace the step flashing with new copper or stainless, and weave it in so every fastener is covered. Rotted decking gets replaced at the same time.
Flashing lifted by ice damming along the roof edge
We reset the flashing, re-secure it to the deck, and rebuild the seal. On problem roofs we add a proper ice-and-water detail so the same thing does not happen next winter.
Cracked chimney crown letting water in above the flashing
We test the crown and flashing separately with a smoke test kit and controlled water test, then fix the actual source. If the crown is cracked, we rebuild it with crown sealant and refractory mortar.

Most flashing repairs in Milford run $350 to $900 in 2026, depending on roof pitch, chimney size, and whether the counter-flashing groove needs to be reground.

The counter-flashing sealant has failed, or the step flashing has rusted through. In Milford, salt air and freeze-thaw cycles speed both up. Water gets behind the metal, runs down the masonry, and shows up as a ceiling stain or rust in the firebox. A smoke test kit and water test confirm the exact entry point before we quote the repair.
