Pittsburgh Premium Roofing provides professional chimney flashing in Pittsburgh, PA for residential and commercial properties across Allegheny County. Chimneys leak more than any other detail on a Pittsburgh roof, and the reason is structural rather than cosmetic. A masonry chimney is a heavy independent column, and in older housing it very often carries its own footing separate from the framing around it.
That means the chimney and the house do not necessarily move together. Seasonal frost, ordinary settlement and, on some lots, slow downslope creep move the frame a little while the masonry mass sits differently. Every millimeter of that difference works the joint between roof and brick, which is exactly where the flashing lives. It is also why the same chimney will leak again five years after a sealant repair, and again five years after the next one.
The durable fix is a two-piece assembly that is designed to tolerate the movement rather than resist it. Along the sides, step flashing runs one piece to a course, woven in with the shingles, and nothing gets face-nailed into the brickwork. A base and apron at the front. A counterflashing let into a sawn reglet, held with lead wedges and sealed at the top only, so the two halves can slide against each other without opening a path.
Any stack broader than roughly thirty inches earns a cricket. A framed and flashed saddle behind the stack sheds water and, more importantly here, sheds the wet leaves and grit that otherwise build into a dam against the back wall and hold moisture against brick through a freeze-thaw winter. Skip it and the back of the stack becomes a bathtub with a slow drain.
We look above the flashing as well. Water gets into a stack from above as well: through a split crown, through spalled face brick, through open head joints, through a flue nobody ever capped. Flashing cannot stop any of that. Unused flues on old Pittsburgh houses are worth capping properly or removing from the roof plane entirely rather than maintaining forever.
Sealant appears in this scope exactly once, at the top edge of the counterflashing, where it is a joint filler and not a structural element. If somebody has previously smeared roof cement over the whole assembly, it comes off, because it hides the failure and traps water against the masonry. Old roof cement comes off in stubborn pieces and it takes time we quote for.
Our licensed and insured team brings the right materials and equipment to every job — weak red claystone weathering under hillside colluvium, a leader carry line dimensioned in feet on the estimate, boxed cornice eaves with no soffit cavity to vent, plywood keyed into sound one-by plank decking, counterflashing set into a sawn mortar reglet with lead wedges, a framed cricket behind any stack wider than thirty inches — and backs the work with a written workmanship warranty. We serve Pittsburgh and nearby communities including Mount Lebanon, Bethel Park, Penn Hills, Ross Township.

Materials, equipment and how we do chimney flashing
The difference between chimney flashing that lasts and chimney flashing that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with weak red claystone weathering under hillside colluvium, a leader carry line dimensioned in feet on the estimate, boxed cornice eaves with no soffit cavity to vent, plywood keyed into sound one-by plank decking, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Pittsburgh job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of roofing work in Allegheny County means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.
