Why call us for chimney flashing repair

Chimney Flashing Repair in Washington, DC: Why Call Us

For chimney leak repair in Washington, DC, call (833) 583-1301. We weave new step flashing under each shingle course, set counter flashing into a ground mortar joint and rebuild flat crowns with a proper slope.

Chimneys are the whole job

Chimney flashing repair and chimney leak repair are what we do. We do not sell full roofs or siding.

Step and counter flashing

Each step piece overlaps the one below and nails to the deck, never the brick. Counter flashing goes into a ground reglet.

Crickets where code calls for them

A chimney wider than 30 inches needs a cricket on the uphill side. We build them when they are missing.

Masonry done right

Soft lime mortar on old soft brick. Sloped concrete crowns, not flat mortar caps.

Leaks without a chimney

Wall flashing, skylights, vent boots and valleys use the same methods, and we fix those too.

Photos of the work

You see what failed and what we replaced, which helps if you are talking to an insurer.

How a chimney leak job goes

Four steps to chimney flashing repair in Washington, DC

01

Call and describe the leak

Tell us where the water shows up and when. A stain that only appears in wind-driven rain points somewhere different than water in the firebox.

02

We find the entry point

Our crew checks the crown, the brick face and the step and counter flashing, because a leak at the chimney is not always a flashing problem.

03

You get a plain written scope

We tell you what failed, what we plan to replace and what it costs before any shingle comes off.

04

We fix it with metal, not caulk

New step flashing under each shingle course and counter flashing set into a ground mortar joint. Photos before and after.

Questions about chimney flashing repair

Questions Washington, DC homeowners ask about chimney flashing repair and chimney leak repair.

Call (833) 583-1301
Can you just seal my chimney flashing with caulk?
Caulk is a temporary patch, not a repair. Sealant bonds poorly to dusty brick and breaks down in the sun, so a caulked joint usually fails within a couple of years. A lasting fix is step flashing under each shingle course with counter flashing set into a ground mortar joint above it.
What is the difference between step flashing and counter flashing?
Step flashing is the set of small L-shaped pieces tucked under each shingle course along the side of the chimney. Counter flashing is the metal set into the brick that laps down over the step flashing. The two work as a pair. One without the other leaks.
Do I need a chimney cricket?
Building code calls for a cricket on the uphill side of any chimney wider than 30 inches, unless the chimney sits on the ridge. Even on a narrower chimney, a cricket helps if you see leaves piling up or water ponding behind the brick after a storm.
What metal do you use for chimney flashing?
On most asphalt shingle roofs we use aluminum or galvanized steel. On slate, cedar or historic homes we use copper, which lasts as long as the roof. We avoid pairing copper with galvanized steel or aluminum on the same detail because the two corrode each other.
Why does my chimney leak only in heavy storms?
Light rain runs off. Heavy, wind-driven rain gets pushed sideways into loose counter flashing, through open mortar joints and into an uncapped flue. If your leak only shows up in big storms, the flashing and the brick face are the first things we check.
