Chimney & Skylight Flashing Leaks in New Braunfels, TX: Find the Real Source

0:00 / 1:05

Key takeaways

Step flashing and counterflashing seal where the roof meets a wall, chimney, or skylight.
Sun-cracked sealant and loose metal are common failure points.
A ceiling stain can sit feet away from the real opening.
Rebuild the flashing. More caulk on top is not a lasting fix.

Read the transcript

0:00 Intro. This guide explains why chimneys and skylights leak so often in New Braunfels, Texas, and how a roofer finds the exact spot.

0:11 Why flashing fails. Flashing is the metal that seals the joint where a roof meets a wall, chimney, or skylight. Step flashing is woven in with each shingle row. Counterflashing covers the top. Old sealant cracks in the Texas sun, and loose pieces let water slip behind.

0:30 Hidden water paths. Water that gets past flashing rarely drips straight down. It runs along the deck, rafters, or skylight frame first. That is why the stain on your ceiling can be several feet away from the real opening.

0:46 Pinpoint repair. A careful roofer traces the path from the attic and the roof above the stain. The fix is to rebuild the failed flashing the right way, not to smear more caulk on top. Ask for photos before and after the repair.

Start with what you see

What is happening with your roof?

Choose a symptom for likely causes and a safe next step. This guide does not replace an on-roof inspection.

Likely places to check

Ceiling leak

Common causes include a pipe boot, roof valley, vent, skylight, or damaged shingle above the wet area.

Do this now: Move valuables, catch the water, turn off power near wet fixtures, and photograph the stain.

Find the true entry point

Step flashing

Small metal pieces weave into each shingle course where a roof meets a wall.

Counterflashing

The upper metal sheds water over base flashing at masonry and wall joints.

Skylight kits

The correct flashing kit must match the skylight, roof pitch, and roofing material.

Old sealant

Caulk can crack in heat and movement. It should not replace correctly layered flashing.

Built for this area

New Braunfels heat, hail, wind, and hard rain

Comal County roofs face long sun exposure, fast temperature changes, strong storms, and wind-driven rain. A sound flashing and skylight leak repair plan must manage water at every joint, allow materials to move with heat, and keep attic airflow balanced.

Roof anatomy

Five places where roof systems fail

Ridge and vents

Heat and moisture leave through balanced exhaust. Loose caps and failed vent flashing can admit rain.

Roof field

Shingles or panels shed water. Cracks, punctures, lifted seams, and worn surfaces reduce protection.

Valleys

Two slopes collect water here. Debris, poor laps, and damaged underlayment can create fast leaks.

Walls and chimneys

Step and counterflashing must move water over the roof instead of relying on surface caulk.

Eaves and gutters

Drip edge, starter material, intake airflow, and clear drainage protect the roof perimeter.

Make the right-sized choice

Repair or replace?

Repair may fit

One failed flashing joint, seal, skylight part, or nearby roofing area that can be rebuilt into sound materials.

Replacement may fit

A failed skylight body, widespread flashing errors, rotten decking, or an older roof with several connected leak paths.

The roof age, damage spread, deck condition, material match, and written scope should decide the recommendation—not a sales shortcut.

How the leak is narrowed down

Step 1
Read the stain
Check the ceiling and attic for the highest wet point, dark wood, and fastener marks.
Step 2
Inspect the outside
Look for lifted metal, missing laps, cracked corners, and debris channels.
Step 3
Use controlled water
When safe and useful, wet one small roof zone at a time while someone watches inside.
Step 4
Repair the layers
Rebuild the failed flashing detail and replace damaged nearby roofing as needed.

What changes the cost of flashing and skylight repair in New Braunfels?

Every roof is different. Your exact price comes after the roof is checked.

Factor	Smaller job	Bigger job
Where it leaks	One pipe or small vent	Chimney or large skylight
Flashing type	Reseal good metal	New step and counter flashing
Skylight	Reflash the frame	Replace the skylight unit
Chimney masonry	Solid brick	Cracked mortar to fix first

Repair, reflash, or replace

Reseal

Best for a small failed exposed seal where the main flashing is still correct.

Reflash

Needed when metal is missing, lapped wrong, loose, corroded, or buried behind bad layers.

Replace the skylight

Worth considering when the frame, glass seal, or skylight body has failed, not just the roof joint.

Common questions

Why does my skylight leak only in hard rain?

Wind-driven rain can reach a weak side or head-flashing joint that normal rain does not test.

Can caulk stop a chimney leak?

It may stop a small surface gap for a time. Missing or badly layered flashing usually needs to be rebuilt.

What is a controlled water test?

One small roof area is wet at a time while someone watches inside. It can help isolate a leak when conditions are safe.

Could the skylight glass be the problem?

Yes. Condensation, a failed glass seal, frame trouble, and roof flashing can create different symptoms.

Will nearby shingles need removal?

Often, yes. Correct flashing sits under and between roofing layers, so nearby material may need careful removal and replacement.
