What Flashing Is and Where It Fails

Flashing is shaped metal that directs water away from roof joints and transitions. Step flashing protects sidewalls, counter-flashing covers the upper edge of flashing, headwall flashing protects the top of a roof slope and valley metal carries water where two slopes meet.

Check every visible roof-to-wall joint for rusted, lifted or tarred-over metal. Gaps beneath siding, loose counter-flashing and a split or corroded valley are signs that the joint needs closer inspection.

Wall-to-Roof Joints: The Common Leak on These Houses

Sidewalls and dormers leak when step flashing is missing, poorly lapped or no longer covered correctly by siding or counter-flashing. Roof movement can open these joints, and water may then run behind the wall covering before it appears on a ceiling.

A sealant-only fix keeps failing because sealant cannot recreate the overlapping path formed by individual pieces of step flashing. Thick tar can also hide rust, loose metal and an incorrect lap. Check for sealant lines that have cracked or pulled away at the corners of a dormer or sidewall.

How a Flashing Leak Is Repaired

A flashing leak is repaired by opening the joint and rebuilding the water-shedding layers in the correct order.

Confirm the leaking joint from the attic side and note where the wall, roof deck and stain align.
Open the shingle courses next to the wall without damaging reusable roofing.
Remove and replace failed step flashing rather than sealing over it.
Weave counter-flashing into the masonry joint where that detail is required.
Reset the wall covering and re-lay the shingles so each course overlaps correctly.
Perform a controlled water test directly at the wall and check the attic side.

Flashing or the Shingle Field? How to Tell

The stain location can narrow the search, but the actual entry point is often higher than the visible interior damage.

Where the stain shows inside	Where water may enter	What to check
At the ceiling and wall line	A wall-to-roof joint above the stain	Step flashing, headwall flashing, siding clearance and lifted laps
Beside a chimney	The upslope or side flashing around the chimney	Step flashing, counter-flashing and open masonry joints
Below a roof valley	Higher along the valley	Split valley flashing, corrosion, debris and incorrect shingle laps
Around a plumbing vent	The pipe boot directly upslope of the stain	A split rubber collar, lifted flange or exposed fastener

A stain below the open shingle field may still come from a wall, valley or pipe boot because water can travel along the roof deck or a framing member.

Flashing Repair Costs Depend On

Flashing repair cost depends on how much of the joint must be opened and rebuilt.

Factor	Why it affects the work
Height	Higher joints require more access setup and material handling.
Wall type: masonry versus siding	Masonry may require a cut joint for counter-flashing, while siding may need to be loosened or removed.
Whether the joint must be opened	Hidden step flashing cannot be assessed or replaced without opening the shingles and wall edge.
Whether flashing is reused or replaced	Rusted, bent or incorrectly sized metal must be replaced rather than reset.
Access around dormers	Narrow sidewalls and intersecting slopes can increase the amount of careful removal and reassembly.
Whether shingles have to be re-laid	Shingles removed to reach the flashing must be reset or replaced with the correct overlap.

Frequently asked questions

Why does my roof leak at the wall?

A roof often leaks at the wall because step flashing is missing, loose, rusted or incorrectly lapped. Water can also enter behind siding or counter-flashing and appear below the actual opening.

What is step flashing?

Step flashing is a series of separate metal pieces woven between shingle courses where a roof meets a sidewall. Each piece overlaps the one below it so water stays on the roof surface.

Can you fix flashing without replacing shingles?

Sometimes sound shingles can be lifted and re-laid, but damaged or brittle shingles must be replaced. The correct approach depends on whether the joint can be opened without breaking the surrounding courses.

Why did the tar repair on my flashing fail?

Tar fails when it is used to cover loose metal, rust or incorrect flashing laps. It can crack as the roof and wall move, allowing water to return through the original defect.

Does a valley leak need the whole valley replaced?

Not always. A localized defect may be repairable when the surrounding valley metal and shingles remain sound. Widespread corrosion, split metal or repeated leaks can require the valley to be opened and replaced.
