Flashing and chimney leak repair, done right.
When water finds its way in around a chimney, skylight, or vent, it's almost always the flashing, not the roofing material itself. We track down the failure point and repair it correctly across the Denver Metro and Northern Colorado.
Virtuous Roofing and Exteriors repairs failed flashing at chimneys, skylights, walls, and vents across the Denver Metro and Northern Colorado. Flashing is the metal and sealant that ties a roof plane to anything that pokes through it, and it's the single most common place a roof actually leaks. We inspect the flashing, the framing behind it, and the attic side before we touch anything, then repair or replace what's failed. Most flashing repairs are handled in a single visit.
Is water showing up near a chimney or skylight in your Colorado home?
Most leaks near a chimney, skylight, or vent trace back to flashing, not a failure in the surrounding shingles. Chimneys move independently of the roof structure, so the metal and sealant that bridge the two work loose over time and let water past on the next hard rain. Skylights leak at the flashing kit around the curb or at the seal between the frame and the glass, often at both once a unit gets older. A stain on the ceiling below rarely sits directly under the entry point, since water travels along the decking before it drips through, so tracing it back takes a hands-on look at the roof and the attic.
Warning signs to watch for
Staining around the chimney chase
A brown ring on the ceiling or attic decking near the chimney usually means the counter-flashing has pulled away from the mortar joint. It gets worse with every rain once the seal opens up, and it can spread into the wall cavity if it's ignored.
Water stains below a skylight
Discoloration on the drywall under a skylight points to the flashing kit or the seal around the glass letting go. Older skylights often fail at both points at once, which is why resealing the same spot again rarely holds.
Cracked or lifted pipe boots
The rubber collar around a plumbing vent dries out and splits years before the shingles around it wear out. It's one of the most common leak sources on any roof, and it's easy to miss from the ground.
Rot at a wall-to-roof transition
Where a roof runs into a sidewall, missing step flashing or a missing kickout lets water track behind the siding instead of into the gutter. That hidden path is a classic cause of rotted sheathing that doesn't show up until years later.
What is causing the problem
Chimney movement over time
Chimneys settle and shift separately from the roof framing, so flashing that was tight at installation works loose over years of freeze and thaw. Caulk alone buys a season or two, but the lasting fix is step and counter-flashing set into the mortar joints.
An aging or undersized skylight kit
Older skylight flashing kits weren't built for Colorado's freeze-thaw cycles, and the glazing seal ages at a different rate than the metal around it. Replacing the flashing kit, and sometimes the skylight itself, is often the better repair than resealing it again.
Cracked pipe boots and worn vent flashing
Rubber boots and metal vent flashing have a shorter lifespan than the shingle field around them. When enough of them fail across the roof, spot repairs turn into a pattern worth reviewing during a full inspection.
Missing kickout flashing at a wall
Some homes were built without a kickout where the roof meets a sidewall, so water has been running behind the siding since the day it was framed. Once we find it, the fix is straightforward: install the kickout and reseal the transition.
What to expect during the visit
We start by inspecting every flashing line and penetration on the roof, chimney, skylights, wall transitions, and vents, along with the attic side to see where water has actually been getting in. If the source isn't obvious from the outside, we'll water-test the area to confirm it before we recommend anything. Once we've pinpointed the failure, we repair or replace the flashing, reset counter-flashing into the mortar joints where needed, add a cricket or kickout where one is missing, and reseal the transition. We'll walk you through what we found and what it took to fix it before we leave, and we're reachable at (303) 808-6888 Monday through Saturday if anything comes up afterward.
Related services you may need
If the flashing failure turned out to be storm-related, our Storm Damage & Insurance team can document it for your claim. A roof nearing the end of its life with flashing failing in more than one spot is often a sign it's time to talk through Roof Replacement, and a full Roof Inspection is worth scheduling if you haven't had one in a while.
The cost of waiting
A flashing leak that gets ignored doesn't stay small. Water that's finding its way past a chimney or skylight keeps tracking down the same path every time it rains, soaking insulation, staining drywall, and eventually rotting the decking or framing underneath. What starts as a repair you can do in an afternoon turns into a decking replacement, a mold remediation, or a bigger tear-off once the wood underneath has been wet long enough. Flashing problems also tend to be at their most affordable to fix before the surrounding materials are damaged, so catching it early saves more than just the ceiling.
Can flashing be repaired without replacing the whole roof?
Yes, in most cases flashing repair is a standalone fix. Flashing is a separate system from the shingles or roofing material around it, so we can repair or replace a chimney, skylight, or vent flashing without touching the rest of the roof, unless the surrounding decking has been damaged by the leak.
How much does flashing repair cost in Denver Metro and Northern Colorado?
The cost depends on how many penetrations need attention and whether the framing or decking behind the flashing was damaged by the leak. A single pipe boot or vent flashing repair is a much smaller job than resetting counter-flashing into a chimney's mortar joints or rebuilding a kickout at a sidewall. We'll give you a clear estimate after we've inspected the specific failure.
How do I know if it's flashing or the shingles that are leaking?
The location of the leak is the biggest clue: leaks near a chimney, skylight, vent, or wall are almost always a flashing problem, while leaks in the open field of the roof are more likely a shingle issue. We inspect both the roof surface and the attic side to trace the water back to its actual entry point rather than guess from the ceiling stain.
