The roof junction flashing, face by face
Counter flashing that has pulled away
Counter flashing can pull out of its joint when the mortar softens, when a ladder or roof work bends it, or when strong wind lifts its edge. Once the top edge stands away from the brick, rain can run straight behind the metal.
If the piece itself is sound, it may be refitted into a cleaned or recut joint and sealed again. If it has been bent more than once, it may not sit flat and is better replaced. We explain which applies after handling the metal, not from the ground.
The sealant in the joint
The sealant used at a chimney has to bond to both metal and masonry, stay flexible and handle sun on the roof. Its maker's data sets the surfaces it suits, how it is applied and how long it needs before rain. We choose it from that data, not from what happens to be in the truck.
Ask which sealant we plan to use and where. It should appear at the reglet and at hidden laps, not smeared across open seams. The written record names the product, which helps anyone who has to maintain the joint later.
A chimney on the outside wall
Some chimneys run up the outside of the house, and the roof meets only the side facing the building. The rest of the stack stands clear of the roof. Flashing is needed only where roof and chimney touch, often along one face and part of two others.
The joint between the chimney and the house wall below the roof also has to be sealed. We look at where the roof flashing ends and where that wall joint begins. If either has opened, the findings say which, because each has its own repair and its own line in the estimate.
Stainless grade where salt settles
Not all stainless steel resists salt air equally. Industry guidance on stainless for exterior use ties the grade to the exposure. Places where sea salt settles and rain does not rinse it off are harder on the metal than open faces.
Flashing tucked under roofing and behind counter pieces stays sheltered, which can trap salt deposits. We choose the metal with that in mind and name the grade in the estimate. If you have seen rust-colored staining on existing stainless near the chimney, mention it, because it tells us something about the exposure.

Common questions on reflashing a chimney
Which metal do you use for new chimney flashing?
We choose it for the chimney and the roof, and brick industry guidance favors stainless steel or copper for chimney work. The code sets a minimum thickness for metal flashing. The estimate names the metal, so you know what goes on before you approve.
Does a new roof come with new chimney flashing?
Not necessarily. Some roofers replace the base pieces and leave the counter flashing, and some reuse old metal. Ask your roofer what is planned for the chimney. We can assess the counter flashing before the new roofing goes on.
Do you seal chimney flashing with roof cement?
Not as the main seal. Roof cement is a roofing patch material, and a flashing joint should rely on lapped metal with sealant at the reglet and hidden laps. Where old cement hides the metal, we clean it back to see what is underneath.
