Oshkosh Premium Roofing provides professional chimney flashing in Oshkosh, WI for residential and commercial properties across the Lake Winnebago basin. We flash chimneys correctly and we still tell a fair number of customers that flashing was never their problem. On the lumber-era masonry in this city, the water is frequently coming through the brick itself, and no amount of metal work fixes that.
Oshkosh has a lot of old chimney stacks built with soft brick and lime mortar. Those materials were chosen to be permeable on purpose so a stack could dry. On the lakeward face of a house, that same permeability meets rain arriving sideways and driven into the wall at pressure for hours at a stretch, and the masonry saturates through to the inside face.
The tell is the location and the timing of the stain. Flashing failures stain the ceiling immediately around the chimney chase, and they leak on any sustained rain at all. Saturated masonry stains further down instead, often on the chase wall a full floor below, and it shows up only after a long blow from the water side of the house. We check for both before we quote either one, because they cost very different money.
When it is the flashing, the work is specific. Step flashing woven into every course with a vertical leg taller than the shingle exposure. Two-piece counterflashing let into a raked joint and locked, not a bib of sealant smeared on the brick face, which is what we pull off most often. A cricket behind any stack over about thirty inches wide, so water is split around it instead of collecting on the upslope side.
When it is the masonry, the answer is a masonry answer: a proper overhanging crown with a drip edge cut into it, a rain cap, repointing on the exposed elevation, and a vapor-permeable repellent that still lets the stack dry outward. We will name what needs doing and hand you two mason names, because that is not our trade and pretending otherwise costs you twice over.
The one thing we will not do is flash a chimney, take your money for it, and let you find out in November that the stain was never coming from the roof in the first place. If we believe the masonry is the source, we say so at the estimate, in writing, and before you have paid us anything at all.
Our licensed and insured team brings the right materials and equipment to every job — reduced shingle exposure on the lakeward planes, gutter apron tucked behind the trough and over the fascia, self-adhered ice barrier carried the full run of a lakeward slope, step flashing formed with a taller vertical leg than the shingle exposure, two-piece counterflashing bedded in a raked masonry joint, hemmed rake metal with a closed end at the eave return — and backs the work with a written workmanship warranty. We serve Oshkosh and nearby communities including Fond du Lac, North Fond du Lac, Taycheedah, Black Wolf.

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 reduced shingle exposure on the lakeward planes, gutter apron tucked behind the trough and over the fascia, self-adhered ice barrier carried the full run of a lakeward slope, step flashing formed with a taller vertical leg than the shingle exposure, 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 Oshkosh 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 the Lake Winnebago basin means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Oshkosh Chooses Oshkosh Premium Roofing
- ✓We ask what direction the wind was blowing when you saw the stain, because on this shore that answer separates a driven-water path from an actual hole faster than an hour on the roof does
- ✓Hose testing is done up the slope and up the wall, never just straight down, since water that entered sideways will not reproduce under a test that respects gravity
- ✓We will quote two planes rather than four when the lakeward side is spent and the street side is not, and we will tell you plainly what a two-plane roof costs you in color match
- ✓Underlayment run and headlap are line items you can compare between bidders, not assumptions folded into a price per square
The standards behind chimney flashing
Quality here is not a matter of opinion — it is written down. The chimney flashing work we do in Oshkosh follows published industry standards: NRCA publishes the Roofing Manual, the industry's reference for details and slope minimums, and Asphalt Roofing Manufacturers Association sets the shingle application and ventilation guidance the warranties reference. If a contractor cannot tell you which standard a detail comes from, that is worth asking about before you sign.
