Choosing the flashing metal

Copper, stainless steel, galvanized steel and aluminum all turn up as chimney flashing, and they do not behave alike next to wet masonry, a roof covering and its fasteners. Copper and stainless steel hold up best against brick. Aluminum is kept out of contact with fresh mortar, whose alkalis attack it, and galvanized steel is not what the Brick Industry Association recommends for chimneys.

The roof on your Brentwood house also shapes the choice. The metal has to be compatible with a metal roof and with the fasteners, so we name the flashing metal and explain the choice. Roof-line checks in Brentwood cost nothing; call (904) 920-5495 to book the first dry day.

Brentwood sits away from the coastline. Brentwood is a neighborhood inside Jacksonville city limits.

From attic check to sealed reglet in Brentwood

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.

Debris behind the chimney on Brentwood roofs

The uphill face of a chimney catches leaves, twigs and shingle grit washing down the roof. Packed against the back pan, that debris holds water and lets it back up under the metal in heavy rain.

On Brentwood roofs we clear the dam, check the back pan for rust, and say whether a cricket would keep the area clear.

Hemmed edges on the flashing

The exposed lower edge of counter flashing is folded back on itself, a hem, rather than left as a raw cut edge. The hem stiffens the metal so it lies flat against the base flashing instead of curling, and it gives water a clean edge to drip from.

A raw edge can ripple, lift in wind and let water wick back underneath. On aprons and counter flashing we hem the exposed edges where the metal allows it. It is a small thing that makes the joint last longer and look finished from the ground. Hems are formed on the bench before the piece goes up.

Why aluminum stays away from fresh mortar

Aluminum flashing is light, cheap and easy to bend, and it turns up on chimneys for those reasons. The problem is contact with masonry. According to the Brick Industry Association, fresh mortar is alkaline enough to corrode aluminum, so aluminum is not a flashing metal for brickwork.

Aluminum set into a reglet with fresh mortar, or lying in constant contact with wet brick, corrodes where it touches. We use copper or stainless steel for anything set into the masonry, and where a roof requires aluminum for compatibility, the detail keeps the aluminum away from the brick with a separate counter flashing.

Copper flashing and the staining below it

Copper is a durable flashing metal for chimneys. It handles the temperatures, it can be set into fresh mortar, and it solders into clean corners. The Brick Industry Association lists one drawback: runoff from copper can stain the crown or the brick below it.

That stain is a greenish or dark streak, and on light brick or stucco it can be visible from the ground. Where staining would be a problem, stainless steel is the alternative. If you choose copper, that possibility is mentioned up front, so staining does not come as a surprise a year later. Copper also darkens as it weathers, which some owners like and some do not.

What decides the flashing detail

Failed pieces identified by side: apron, steps, back pan or corners
Roof covering type, and the maker's or manual's flashing detail
Counter flashing method, reglet or through-wall, with the reason
Removal of old tar, cement and caulk so the joint can be judged

Flashing questions from Brentwood

Does a little rust mean the flashing has to be replaced?

Not necessarily. Light surface rust on otherwise sound metal can be watched. Holes, flaking or rust along the roof line mean the piece has failed and should be replaced.

Is flashing work eligible for the 10% off?

Yes. Book the flashing work in the 72 hours after your free inspection and it comes 10% off, like any other service. Mention it when you book.
