What our flashing leak repair includes
Every flashing repair starts with a full inspection of the leak area and the attic side. We then rebuild the failed flashing with new metal, seal the joints with manufacturer-grade caulk, and test the repair with water before we leave. Here is what is covered in a standard visit.
Full leak inspection
We check the roof surface, flashing details and attic with a moisture meter and infrared thermal camera. You get photos of what failed and a clear explanation of why it leaked, not just a verbal guess.
New flashing installation
We remove the old step flashing, pipe boot, counter-flashing or valley metal and install new material sized to your roof. Shingles get reset with proper nailing, and the new flashing ties into the existing courses.
Sealant and underlayment
Seams get Sika or Henry polyurethane sealant, and we add Grace Ice & Water Shield where the old underlayment has failed at valleys or wall transitions. That combination handles Knoxville's rain and temperature swings.
Hose test verification
Before we pack up, we run water over the repaired area with a hose test kit and watch the attic side for drips. If anything is still wet, we keep working until it is dry. You see the test result.
Photo report and cleanup
We email you before-and-after photos of the repair, magnet-sweep the yard for nails, and haul off the old flashing. You get a written record of the work for your home files.
Homes and businesses.
The approach is the same for a home and a business. What changes is the access, the schedule and who needs the paperwork.

Roof flashing leak repair Knoxville TN done right
A plain-language look at what Roof Flashing Leak Repair involves and when it is needed.
See how it worksRoof flashing leak repair Knoxville TN is the trade of rebuilding the metal and sealant joints that keep water out of your roof's weak spots. Flashing is the aluminum, copper or galvanized steel that wraps chimneys, walls, valleys, vents and pipe penetrations. When caulk shrinks, nails back out, or step flashing rusts through, water walks straight into your attic. We pull the failed pieces, replace them with new metal, and tie them back into the shingles so the roof sheds water the way it was built to.
Knoxville gets about 50 inches of rain a year, plus summer thunderstorms that drive water sideways under lifted flashing. Homes in Fountain City and Holston Hills often have 20- to 40-year-old chimneys with original flashing that has finally given up. If you have been searching for flashing leak repair near me Knoxville, that is usually the moment a stain shows up on the ceiling. We handle roof flashing repair Knoxville Tennessee wide, from single pipe boots to full chimney re-flashing.
Flashing leaks start at the metal, not the ceiling stain.

Tools and methods we use
Move across a circle, or focus it and press Enter, for an illustrative thermal view of the photograph.
Infrared thermal camera
Finds wet decking and insulation behind ceilings without tearing into the drywall. We use it to trace the leak path from the attic side.
Moisture meter
Confirms which framing and sheathing is wet so we know how far the repair needs to extend. It also tells us when the area has dried.
Hose test kit
Applies controlled water to the repaired flashing while we watch the attic side. It is the final check before we call the job done.
Roof ladder and roof snake
Gets us safely onto steep pitches and lets us lift shingles without tearing them. Both are standard on every truck.
Caulking gun and pry bar
Applies Sika and Henry sealants precisely and removes old flashing without damaging the surrounding shingles.
Thermal views are illustrative, generated from the photographs.
Methods
Drone inspection
Checks tall chimneys and steep roofs from the air when walking them is not safe. We use it to document conditions before and after repairs.
Layered flashing rebuild
We rebuild flashing in the same layered order the roof was designed for: ice and water shield first, then step flashing, then shingles, then counter-flashing. Each layer sheds water to the next, so a single failed seal does not become a leak.
Water-test verification
Every flashing repair gets a controlled hose test before we leave. We watch the attic side for drips and do not consider the job finished until the area stays dry under running water.
Photo documentation
We photograph the failed flashing, the new installation and the test result. You get the images by email, which gives you a record of the work and helps with any future roof questions.
Manufacturer-spec fastening
We follow GAF, Owens Corning and CertainTeed nailing patterns for shingles around flashing. Correct fastener placement keeps shingles from lifting and reopening the leak path.
When Knoxville homeowners call us
Storm stain traced
A ceiling stain appears after a heavy thunderstorm in South Knoxville.
We inspect the attic with a moisture meter, trace the wet path to a failed pipe boot, and replace the boot the same day. A hose test confirms the fix before we leave.
Outcome: The stain stops growing and the ceiling dries out. You get photos of the old boot and the new one for your records.
Chimney re-flash
An older home in Old North has original chimney flashing that has never been replaced.
We rebuild the chimney flashing with new counter-flashing and step flashing, then seal the masonry joint. The repair is tailored to the brick and roof pitch.
Outcome: The chimney stops leaking and the attic stays dry through the next rainy season. The new flashing should last 20 years or more.
Rental roof block
A property manager in West Knoxville needs several rental roofs inspected after a windstorm.
We inspect each roof, document lifted flashing and missing shingles, and provide a photo report with repair pricing per unit. Repairs are scheduled in one block.
Outcome: All the flashing issues are corrected and the manager has documentation for each property. No surprise leaks at turnover.
Skylight curb seal
A homeowner in Farragut notices water dripping near a skylight during a storm.
We check the skylight curb flashing and find the sealant has failed. We re-flash the curb, replace the sealant, and test with water.
Outcome: The skylight stops leaking and the ceiling below stays dry. The repair costs far less than replacing the skylight.
Wall flashing repair
A homeowner in Cedar Bluff sees a water stain spreading on the ceiling two days after rain.
We trace the leak to a failed roof-to-wall flashing detail, replace the step flashing and counter-flashing, and seal the joint. A hose test verifies the repair.
Outcome: The stain stops spreading and the wall cavity dries out. The repair is documented with photos for the homeowner's records.
How flashing repair runs in Knoxville
Knoxville's climate is hard on flashing. We get roughly 50 inches of rain a year, plus freeze-thaw cycles in January that work caulk loose and ice dams that push water under flashing at the eaves. Summer storms drive rain sideways, which finds every lifted step flashing and cracked pipe boot.
Homes in older neighborhoods like Old North, Lonsdale and Chilhowee Hills often have original chimney flashing that has finally rusted through. Newer builds in Hardin Valley and Turkey Creek tend to have pipe boot failures first. We work to Tennessee code requirements and use materials rated for the local temperature range.
If you need a flashing leak fix Knoxville homeowners trust, we know where these roofs fail and how to correct them.
- Fountain City: Many homes here have brick chimneys with original flashing. We see a lot of rusted counter-flashing and failed masonry joints.
- Holston Hills: Steep pitches and mature trees mean valleys collect debris. We often find corroded valley metal and debris-damned water backing up.
- West Knoxville: A mix of older ranches and newer builds. Pipe boot failures and roof-to-wall flashing leaks are the most common calls.
- Farragut: Larger homes with complex rooflines mean more flashing transitions. Dormers and skylights are frequent leak sources.
- UT Campus: Older rental housing with deferred maintenance. We see missing shingles and nail pops that open flashing seams.
- Freeze-thaw cycles in winter: Ice expands under flashing and pushes it loose. We check for lifted metal and reseal joints before spring rains find them.
We walk the roof and attic, explain what failed, and show photos. We protect your landscaping and set up safely before starting work. We hose-test the repair, clean up, and email the photo report.
From problem to finished result.
Chimney flashing rebuild in Fountain City
Before: A 1950s brick chimney had original counter-flashing that had rusted through. Water ran down the chase and stained the ceiling in the room below. The attic insulation was wet in a two-foot circle around the chimney.
After: We removed the old flashing, installed new step flashing and counter-flashing, and sealed the masonry joint. The hose test ran clean. The ceiling stain stopped growing and the insulation dried out within a week.
Check the chimney flashing each spring for lifted metal or cracked sealant. A quick sealant touch-up every few years keeps the joint watertight.
Pipe boot replacement in Bearden
Before: A cracked rubber pipe boot was dripping water onto the hallway ceiling every time it rained. The stain had spread to about 18 inches across. The homeowner had tried roof cement as a temporary fix, but it failed within weeks.
After: We cut out the old boot, installed a new one sized to the pipe, and sealed it into the shingles. The hose test showed no drips. The ceiling dried and the stain stopped spreading.
Inspect the rubber collar on your pipe boots once a year. If it looks cracked or brittle, replace the boot before it starts leaking.
Valley metal repair in Holston Hills
Before: Corroded valley metal and trapped leaves caused water to back up under the shingles. The decking along the valley was soft and the attic showed a long wet streak. The homeowner noticed a stain spreading across the ceiling after a storm.
After: We cleared the debris, replaced the valley metal, and installed new ice and water shield under the shingles. The valley now drains freely. The decking was replaced and the attic dried out.
Keep valleys clear of leaves and debris. An annual roof check in the fall prevents water from backing up under the flashing.
Flashing problems we fix in Knoxville TN
Flashing leaks show up in a handful of predictable ways. Knowing which one you have helps us bring the right materials and finish the repair in one visit.
- Rusted chimney flashingChimney flashing rusted throughWater runs down the brick and into the attic, soaking insulation and staining ceilings near the chimney chase. We remove the old counter-flashing and step flashing, install new metal, and seal the masonry joint with polyurethane caulk. The chimney gets a new water-shedding detail that matches the roof pitch.
- Cracked pipe bootPipe boot collar crackedA cracked rubber collar lets water drip straight down the pipe into the ceiling below, often showing up as a ring stain. We cut out the old boot, install a new one sized to the pipe, and seal it into the shingles. Most pipe boot leaks are fixed in under an hour once we are on the roof.
- Loose step flashingStep flashing pulled loose at a wallWind driven rain gets behind the siding and rots the wall sheathing and framing over time. We replace the step flashing and counter-flashing, then reseal the wall joint. The repair restores the layered drainage path so water cannot get behind the siding.
- Corroded valley metalValley metal corrodedWater backs up in the valley and finds seams, leaking into the attic and soaking decking along the valley line. We rebuild the valley with new metal and ice and water shield, then reset the shingles on both sides. The valley drains properly again and the leak path is closed.
Why Knoxville homeowners call us for flashing leaks
A proper flashing repair stops the leak and protects your decking and ceilings.
Stop the leak today
Most flashing leak repairs take two to four hours once we are on the roof. We carry step flashing, pipe boots, ridge cap and Henry roof cement on every truck, so a typical chimney or vent leak gets sealed the same visit instead of waiting on a parts order.
Find the real source
Water can enter at a pipe boot leak and show up eight feet away at a ceiling fan. We use a moisture meter and infrared thermal camera to trace the path, then confirm with a hose test kit before we cut or seal anything. No guesswork, no repeat callbacks.
Protect the deck and insulation
A slow flashing leak soaks decking and insulation for months before you see a stain. We replace rotten sheathing and wet underlayment while we are in there, which protects the structure and keeps mold from taking hold in your attic.
Work that holds up to Tennessee storms
We install Grace Ice & Water Shield at valleys and wall transitions, then seal with Sika or DAP polyurethane caulk rated for the temperature swings Knoxville sees. That combination handles ice dams in January and 95-degree July afternoons without cracking out.

Frequently asked questions about flashing leaks
A single pipe boot replacement sits at the low end. Chimney re-flashing with new counter-flashing and step flashing lands higher because it takes more time and material. We give you the flat price after the inspection, before any work starts.
The usual cause is failed sealant or rusted metal at a penetration. Tennessee sun bakes caulk until it cracks, then wind driven rain pushes under the lifted edge. Nail pops and missing shingles around the flashing make it worse. We see it most on chimneys and pipe boots older than 15 years.
