What Our Dormer Roof Leak Repair Includes
Every dormer repair starts with a full inspection and ends with a hose test. Here is what is covered in a standard visit, and what we quote separately if we find it.
Full Dormer Inspection
We inspect the dormer from the roof and from inside the attic. Moisture meter readings on the sheathing, infrared thermal camera on the ceiling, and a visual check of the step flashing, valley, and pipe boot. You get a clear diagnosis before any repair starts.
Step Flashing Replacement
We remove the old flashing, install new metal, and set it under the shingles and against the wall per manufacturer spec. New Grace Ice & Water Shield goes behind it where it is missing.
Sealant and Underlayment
We seal every lap with Henry or Sika roof sealant and replace torn underlayment with new synthetic felt. If the ice and water shield at the dormer wall is gone, we install new material before the flashing goes back down. This is what makes the repair last.
Shingle Reset and Nailing
We reset the shingles around the dormer with a nail gun using ring-shank nails, and replace any that cracked during removal. Ridge cap and field shingles are checked for nail pops and lifted tabs while we are up there. Most repairs use 15 to 30 shingles.
Hose Test and Photo Report
We run a hose test kit at the dormer wall for 10 to 15 minutes with a second tech watching inside. If it stays dry, we clean up with a magnet sweep and send you photos of the repair plus a written summary of what we replaced.
Cleanup and Haul-Away
Old flashing, torn underlayment, and broken shingles go in the truck, not your yard. We magnet-sweep the lawn and driveway for nails before we leave. You get a dry dormer and a clean property, not a pile of debris by the garage.

What Dormer Roof Leak Repair in Knoxville Actually Involves
A plain-language look at what Dormer Roof Leak Repair involves and when it is needed.
See how it worksDormer Roof Leak Repair in Knoxville means chasing water back to where it enters, not just where it drips. Dormers have two roof-to-wall joints, a valley on each side, and step flashing that takes the brunt of wind-driven rain. We pull the shingles back, inspect the underlayment and step flashing, then rebuild the layers in the right order. Most dormer leaks trace to failed flashing, not the shingles themselves.
Knoxville gets 50-plus inches of rain a year, and dormers on older homes in Fountain City and Sequoyah Hills take the worst of it. Ice dams form on north-facing dormer slopes in January, and summer storms drive water sideways into flashing joints. If you have been searching for dormer roof leak repair near me Knoxville, we handle the whole repair, not just a patch.
A dormer leak is almost always a flashing failure, not a shingle failure.
- What it is
- Repair of the flashing and underlayment at a dormer wall joint to stop water entry.
- When you need it
- When you see a ceiling stain, wall water, or attic moisture near a dormer.
- What to expect
- Inspection, flashing replacement, shingle reset, and a hose test before we leave.
Our Dormer Leak Repair Process, Step by Step
Here is exactly what happens from your first call to the final hose test. No surprises, no vague timelines.
-
Phone Triage
When you call, we ask where the water shows up, how long it has been leaking, and whether the ceiling is bulging. That tells us if you need an emergency tarp or a scheduled repair. We give you a window, not a four-hour maybe. Most calls get a tech on site within 24 hours.
- Phone triage
- Leak history
- Schedule window
-
Roof Inspection
We climb the dormer with a roof ladder, run a moisture meter across the sheathing, and use an infrared thermal camera on the ceiling inside. That combination finds the entry point even when the shingles look fine. Inspection takes 30 to 45 minutes on a typical dormer.
- Roof ladder
- Moisture meter
- Thermal camera
-
Leak Diagnosis
We pull back shingles at the dormer wall joint, check the step flashing, pipe boot, and valley. If the underlayment is torn or the ice and water shield is missing, we note it. You get a clear explanation of what failed and what it takes to fix it before we start.
- Shingle lift
- Flashing check
- Underlayment check
-
Repair and Seal
We replace the failed step flashing, install new Grace Ice & Water Shield where it is missing, and reset the shingles with a nail gun. Every lap gets Henry or Sika sealant. A standard dormer repair runs two to four hours depending on how much flashing has to come out.
- Flashing replace
- Sealant apply
- Shingle reset
-
Hose Test and Cleanup
We run a hose test kit at the dormer wall for 10 to 15 minutes while a second tech watches inside. If it stays dry, we button up, magnet-sweep the yard for nails, and send you photos of the repair. If it leaks, we are still on the roof and we fix it before we leave.
- Hose test
- Photo report
- Magnet sweep
Tools and Methods We Use on Dormer Leaks
Move across a circle, or focus it and press Enter, for an illustrative thermal view of the photograph.
Infrared thermal camera
Finds wet sheathing and insulation behind the drywall without opening the ceiling. We use it on every dormer inspection to map how far the water has spread.
Moisture meter
Confirms whether the sheathing and framing are wet and how wet. Readings tell us if the leak is active or has been dry for a while.
Hose test kit
Simulates wind-driven rain at the dormer wall so we can reproduce the leak on demand. We use it again after the repair to confirm the fix.
Roof ladder and roof snake
Gets us onto the dormer safely and lets us lift shingles without tearing them. The roof snake slides under shingles to set nails without damaging the course above.
Pry bar, hammer, and nail gun
Removes old flashing and shingles and sets the new ones with ring-shank nails. We use a nail gun for speed and consistency on the shingle reset.
Thermal views are illustrative, generated from the photographs.
Methods
Caulking gun
Applies Henry and Sika roof sealant at the flashing laps and wall joint. Clean, controlled beads are what keep water out of the joint long term.
Drone inspection
Lets us check steep or tall dormers and the surrounding roof without walking the whole slope. Useful for documenting storm damage before we get on the roof.
GAF Master Elite installation standards
That means the right underlayment, the right nailing pattern, and the right flashing detail at the wall.
Grace Ice & Water Shield at the wall joint
We install Grace Ice & Water Shield behind the step flashing at the dormer wall. It is the layer that stops ice dam water and wind-driven rain from getting under the shingles. If it is missing, the flashing alone will not hold.
Step flashing per manufacturer spec
Step flashing has to be woven into the shingle courses, not face-nailed over them. We set each piece under the shingle above and over the one below, then seal the laps. Done right, it sheds water for decades.
Hose test verification
We do not call a dormer repair done until it passes a hose test. A second tech watches inside while we run water at the wall joint for 10 to 15 minutes. If it stays dry, the repair is complete.
When Knoxville Homeowners Call Us for Dormer Leaks
Fountain City flashing
A ceiling stain appears under the dormer after a heavy spring storm in West Knoxville.
We inspect the dormer wall joint and valley, run a moisture meter on the sheathing, and replace the failed step flashing. If the underlayment is torn, we replace that too. The repair usually takes two to three hours.
Outcome: The stain stops growing after the next rain, and you have photos of the new flashing for your records.
Bearden ice dam
Ice dam water backs up under the dormer shingles in January in Fountain City.
We remove the shingles at the eave, replace the ice and water shield, and reset the flashing that the ice pried loose. If the dormer has no ice and water shield, we install it while we are there.
Outcome: The dormer handles the next freeze without water backing into the wall, and the ceiling stays dry.
Cedar Bluff pipe boot
Water runs down the inside of the dormer wall during a wind-driven rain in Bearden.
We hose test the dormer wall to reproduce the leak, then replace the step flashing and seal the laps with Henry sealant. If the pipe boot nearby is cracked, we replace that in the same visit.
Outcome: The wall stays dry through the next storm, and the repair is documented with photos and a written summary.
Sequoyah Hills pre-sale
A home inspection before sale flags a dormer leak in Sequoyah Hills.
We inspect the dormer, document the failed flashing with photos, and complete the repair before closing. The written summary and photo report go to the buyer and the agent.
Outcome: The sale moves forward with a documented repair, and the new owner has a record of what was replaced.
Halls Crossroads repeat leak
A dormer leak returns every winter in Halls Crossroads and no one has found the source.
We use an infrared thermal camera inside and a moisture meter on the sheathing to trace the water path. The leak usually traces to a valley or pipe boot, not the shingles. We repair the actual entry point.
Outcome: The leak stops recurring, and you stop paying for patches that never solved it.
How Dormer Leak Repair Runs in Knoxville
Knoxville sits in a valley with 50-plus inches of rain a year and a freeze-thaw cycle that works flashing loose every winter. Dormers on older homes in Old North and Sequoyah Hills were often built with minimal step flashing and no ice and water shield, which is why they leak first. Newer homes in Cedar Bluff and Hardin Valley have better details, but UV still breaks down the sealant within five to seven years. When you call for a dormer leak fix Knoxville TN, we bring step flashing, Grace Ice & Water Shield, and Henry sealant on the truck so most repairs are done in one visit.
- Old North: Many 1920s bungalows here have dormers built with minimal flashing and no ice and water shield. These are the dormers that leak first in a hard rain.
- Sequoyah Hills: Steep dormer slopes and mature trees mean more debris in the valleys. We clear the valley and check the step flashing on every visit.
- Cedar Bluff: 1990s two-story homes with dormers that are now 30 years old. The original sealant is usually gone, and the step flashing has started to lift.
- Fountain City: North-facing dormer slopes here catch ice dams in January. We add ice and water shield at the eave when it is missing.
- Farragut: Larger homes with multiple dormers and complex valleys. We inspect each dormer separately because the flashing details differ from one to the next.
- 50-plus inches of annual rain: Dormer flashing takes constant water exposure, so small failures turn into active leaks fast. We check the wall joint on every inspection.
We walk the dormer and explain what we see We protect the area and set up the ladder We hose test and send photos after
From problem to finished result.
Fountain City Dormer Flashing Replacement
Before: A homeowner in Fountain City had a ceiling stain under the dormer that grew after every rain. Two prior roofers had patched the shingles without fixing the flashing. The step flashing was rusted through and the ice and water shield was missing at the wall joint.
After: We replaced the step flashing, installed new Grace Ice & Water Shield, and reset 22 shingles with a nail gun. The hose test ran 15 minutes with no water inside. The ceiling stain stopped growing after the next storm.
Check the dormer wall joint each fall and reseal the flashing laps every five to seven years. Keep the valley clear of leaves so water does not back up under the shingles.
Bearden Ice Dam Dormer Repair
Before: An ice dam in January pried the dormer flashing loose in Bearden. Water ran down the inside of the wall during the thaw and wet the insulation. The homeowner called after noticing a musty smell in the attic.
After: We replaced the flashing, added ice and water shield at the eave, and reset the shingles. The moisture meter readings on the sheathing dropped to dry within a week. No new water entered during the next freeze.
Keep the attic ventilated and the eave clear of debris. If ice dams form again, call before the thaw so we can check the flashing before water gets in.
Cedar Bluff Pipe Boot and Dormer Leak
Before: A Cedar Bluff homeowner had water running down the dormer wall during heavy rain. The pipe boot near the dormer was cracked and the step flashing had lifted. The leak had been active for months and the drywall was soft.
After: We replaced the pipe boot and the step flashing in one visit, sealed the laps with Sika, and hose tested the wall for 12 minutes. The drywall dried out and was patched by the homeowner. Total repair time was about three hours.
Inspect the pipe boot and dormer flashing each spring. Replace cracked boots before they fail, and keep the dormer valley clear of debris.
Dormer Leak Problems We Solve in Knoxville
Dormer leaks show up in a handful of predictable ways. Here are the ones we see most in Knox County and how we fix them.
- Growing ceiling stainCeiling stain under the dormer that grows after every rainThe drywall softens, paint peels, and mold can start within a few weeks. If the leak runs long enough, the ceiling board has to be replaced, not just dried out. We trace the stain back to the dormer wall joint, replace the failed step flashing, and hose test the repair. Most ceiling stains stop spreading after one visit. We document the repair with photos so you have proof for insurance or resale.
- Wall water in stormsWater running down the inside of the dormer wall during stormsWind-driven rain pushes past old flashing and runs down the wall cavity. That wets insulation, framing, and sometimes the electrical box. It is a bigger repair the longer it runs. We inspect the dormer wall joint and the valley on the windward side. New step flashing, fresh ice and water shield, and sealed laps stop the water at the exterior. We tarp the same day if the leak is active.
- Winter ice dam leakIce dam water backing up under the dormer shingles in winterIce dams force meltwater under the shingles and into the dormer wall. This is the leak that shows up in January and February and disappears in spring, which makes it easy to ignore until the damage is done. We replace the flashing that the ice dam pried loose and install new ice and water shield at the eave and wall joint. If the dormer has no ice and water shield at all, we add it. That is the layer that stops ice dam water.
- Wind-driven rain leakDormer leak that only shows up in heavy wind-driven rainIntermittent leaks are the hardest to diagnose and the easiest to put off. Each storm wets the sheathing a little more, and the damage accumulates behind the drywall where you cannot see it. We use a hose test kit to simulate wind-driven rain at the dormer wall. That reproduces the leak on demand so we can see exactly where water enters. Then we repair that detail, not the whole roof.
- Attic mold smellMold smell in the attic near the dormerA dormer leak that has been running for months wets the sheathing and insulation. Mold follows, and so does the smell. By the time you notice it, the leak has usually been active for a while. We inspect with a moisture meter and infrared camera to map how far the water has spread. Then we repair the dormer flashing and recommend what to do about the wet insulation and sheathing. The repair stops new water from feeding the problem.

Dormer Leak Questions Knoxville Homeowners Ask
A simple step flashing replacement with new sealant sits at the low end. If the underlayment and ice and water shield are gone, or the dormer needs new shingles on both slopes, you are at the higher end. We give you the number before we start.
The most common cause is failed step flashing at the dormer wall joint. Knoxville gets 50-plus inches of rain a year, and that joint takes wind-driven rain from the southwest. Ice dams in January pry flashing loose, and UV breaks down the sealant within five to seven years. A moisture meter and infrared camera confirm the entry point before we open anything up.
