Chimney reflashing and flashing repairs in Hillsboro Beach

Choosing the metal for the new pieces

Flashing metal has to resist corrosion and hold its shape where the chimney meets the roof. Brick industry guidance favors stainless steel and copper for chimney work. It advises against aluminum set into fresh mortar, because the alkalis in mortar attack it. Copper can stain the masonry below it.

We explain which metal we propose and why it suits your chimney and roof. If an earlier repair mixed metals, we point that out, because some metals corrode faster where they touch. The metal named in the estimate is the metal that goes on the roof.

Flashing at a framed chimney chase

Some chimneys are a metal flue inside a framed box covered with siding or stucco. Where that chase passes through the roof, the flashing ties into the wall covering and its weather barrier rather than into masonry. The detail looks more like a wall flashing than a brick one.

We check the base pieces, the wall covering above them and how the barrier behind the siding laps over the metal. If the framing inside the chase has softened, that is chase repair, which is written as a separate scope. The flashing work stays with the roof junction.

What to mention when you book

A few details make the first visit more useful. Share what you know, even if some answers are rough guesses.

If you have papers from past roof or chimney work, keep them handy for the visit. We use them as background and still check the junction in person, because a past invoice cannot show how the metal looks today.

• Where the water or stain appears inside the house
• Whether it shows during rain or some time after
• The roof covering and roughly when it was installed
• Any earlier repair at the chimney and who did it

Crown flashing is a separate job

Brick industry details also place flashing under the crown at the top of a chimney, to keep water out of the space around the flue. That flashing belongs with the crown, not with the roof junction. It is built or repaired when the crown is.

We mention it because the two are sometimes confused in quotes. Flashing repair here means the roof junction. If the crown needs attention, it appears as a separate item under its own name, with its own reasons, so you can decide on each.
