What a repair usually runs
- How far the water got (shingles only, or decking too)
- Where it is: flashing, valley, chimney, skylight
- Roof material and how many storeys
- Whether it is leaking right now
Why a small leak never stays small
Water follows the decking. A flashing or pipe-boot fix caught this month is a few hundred dollars; the same leak left through a season soaks the deck and insulation underneath it, and that becomes a section replacement. If you are seeing a stain, it has already been leaking a while.
Most roof leaks don't start in the middle of a shingle field, they start at a joint where the roof meets something else: a chimney, a skylight curb, a wall, or a vent pipe. Precise Roofing repairs flashing across the Denver Metro area, from a reset chimney counter-flashing to a cracked pipe boot. We've done this for 20 years, and the fix is almost always the same idea: get water shedding off the joint the way it's supposed to instead of into it.
Is a stain showing up near your chimney, a skylight, or a wall that meets the roof?
That's a strong sign the flashing at that joint has failed, since chimneys, skylights, and side walls move separately from the roof and the flashing sealing those joints eventually works loose. Caulk-only fixes hold for a season or two before they crack open again. The lasting repair is metal flashing, step flashing woven into the shingles, and counter-flashing set into the mortar or siding, sometimes with a cricket added behind a wide chimney so water doesn't pool against it. Getting the metalwork right the first time is what keeps that joint dry for years instead of months.
Warning signs to watch for
Staining in the attic near a chimney chase
Water tracking down inside the attic close to a chimney almost always means the flashing or counter-flashing at the chimney has separated from the mortar joint. It's an easy fix while it's small.
Drywall staining below a skylight
Older skylights leak at the flashing kit around the curb, at the seal between the glass and frame, or both. Once a unit leaks in two places, replacing the flashing kit is usually a better repair than resealing it again.
A cracked or curling rubber collar at a plumbing vent
The rubber boot around a plumbing vent dries out and cracks 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 sidewall where the roof runs into it
Where a roof meets a wall, step flashing and a kickout at the bottom are supposed to throw water into the gutter instead of behind the siding. A missing kickout is a classic, hidden cause of rotted wall sheathing.
What is causing the problem
Flashing that has pulled away from the mortar or siding
Chimneys and walls settle and move at a different rate than the roof deck, so the flashing sealing that gap works itself loose over years. It needs to be reset or replaced, not just caulked.
A cracked pipe boot or a loose vent flashing base
Rubber ages faster than shingles do, so boots and vent seals fail on their own timeline. Replacing the boot or reseating the vent flashing usually solves it without touching the surrounding shingles.
A missing kickout flashing at a wall
Some roofs were never fitted with a kickout where the roof runs into a wall, which sends water behind the siding instead of into the gutter. It's a small piece of metal that prevents a lot of hidden rot.
Shingles nearby that have also aged out
Flashing can be sound while the shingles around it are curling or cracking, and vice versa. If the whole roof is showing its age, a repair-only approach stops making sense.
What to expect during the visit
We inspect every flashing line and penetration on the roof, not just the one near the stain, since a joint that's failed once usually has neighbors in similar shape. That includes the chimney, skylights, vent boots, and any wall the roof runs into. We check the attic side for staining that confirms where water is actually getting in, and where the source isn't obvious we'll water-test the area. From there we reset, reflash, or replace the failed section and seal it, and we clean up before leaving the job site.
Related services you may need
If flashing damage traces back to a storm, it may be worth a Storm & Hail Damage inspection to document it. And if the roof surface around the flashing is aging out too, Roof Replacement is worth discussing before we're back for another flashing repair.
The cost of waiting
A flashing leak that's easy to dismiss because it's slow ends up doing the most damage, since it runs quietly behind walls and in attics for months before anyone notices. Wood framing rots, insulation gets ruined, and what would have been a metalwork repair turns into a repair that includes replacing sheathing or drywall. Flashing is cheap to fix early and expensive to fix late.
How much does flashing repair cost in the Denver Metro area?
It depends on how many joints are affected and whether there's hidden rot behind the flashing. A single pipe boot swap is a small job, while a chimney reflash with rebuilt masonry work or a rotted wall sheathing repair costs more because of the extra labor involved.
Can flashing be repaired without replacing the whole roof?
Yes, in most cases flashing repair is its own job separate from the shingles around it. It only turns into a bigger conversation if the roof itself is also near the end of its service life.
Do skylights always need to be replaced when they leak?
Not always, but older units that leak at both the flashing and the glazing seal are usually better served by a new flashing kit than another resealing attempt. We'll tell you honestly which one your situation calls for.
