Rusted flashing

Rust on flashing tells us two things: what the metal is, and how long it has been wet. Light rust on a galvanized piece that is otherwise intact can be left and watched. Rust that has eaten holes along the roof line, or flakes when touched, means the piece has failed.

Rusted flashing on a chimney in O'Neil sends us looking for why water stood against it, such as a debris dam or a flat back pan, because replacing rusted metal without fixing the reason it stayed wet sets the new piece up to fail the same way. Roof-line checks in O'Neil cost nothing; call (904) 920-5495 to book the first dry day.

O'Neil is in Nassau County. O'Neil lies near the coast.

How chimney flashing repair runs

Attic and roof line read
Stains on the rafters and the state of each flashing side tell us which pieces failed before anything comes apart.
Old joint taken apart
Tar and loose metal come off, the roofing beside the chimney is lifted, and open mortar joints are repointed.
Base, then counter flashing
Steps, apron and back pan go in under the roofing, then the counter flashing is set into a sawn reglet and sealed.
Roofing reset and rain check
The roofing goes back over the new metal, and after the next heavy rain we check the attic side.

Flashing just back from the beach

O'Neil lies near the coast, close enough for salt to settle on roof metal. Galvanized flashing and plain steel nails rust sooner there than they would farther inland.

On chimneys in O'Neil we fit stainless or copper flashing with matching fasteners, so the joint does not rust out around its own screws.

Stainless steel flashing

Stainless steel resists corrosion and heat and does not stain the masonry below it. The Brick Industry Association recommends Type 304 stainless for chimney flashing, ordered to ASTM A240, and describes it as a good water barrier with excellent chemical resistance.

It is stiffer than copper, so bending it neatly into steps, hems and tabs takes more care, and soldering it needs the right flux. Around masonry it is a strong all-round choice. We name the grade and thickness we plan to use, so proposals can be compared on the metal as well as the labor. Its fasteners are stainless as well, so the joint does not corrode at the screws.

Checking the flashing from inside the attic

From the attic, with a light, we can see the underside of the roof deck around the chimney. Daylight showing through at the chimney edge, dark staining or soft wood on one side, or water trails on the rafters all point to specific pieces of flashing.

We also check that the roof deck stops short of the chimney with the clearance the chimney needs, rather than being jammed against the brick. The attic check is repeated after the first heavy rain following the repair, as the simplest confirmation that the new flashing is doing its job. Any wet insulation found against the chimney is pulled back to dry.

Flashing metal on chimneys near salt water

Close to the coast, salt settles on flashing and holds moisture against it, and metals that last well inland corrode faster. Galvanized steel loses its zinc coating sooner, and fasteners that do not match the flashing metal corrode at the contact point.

For chimneys in this band we choose stainless steel or copper for flashing and fasteners of a compatible metal, following the Brick Industry Association's guidance and each maker's exposure notes. We also look harder at existing flashing along the roof line, because salt-driven corrosion can hide under the lap where the metal stays wet longest. Fasteners there are checked one by one.

Before your chimney is reflashed

Can you reflash my chimney without a roofer?

On a shingle roof in good condition, that is possible, because the shingles right along the chimney are lifted and reset as part of the flashing detail. Tile, metal and membrane roofs can need a roofer for the roofing itself. The estimate names who does what.

Could only one side of the flashing be replaced?

Yes, when the other sides are sound. A counter flashing that has pulled loose on one side can be reset, or one run of steps replaced. The estimate says what stays and why.
