Oshkosh Premium Roofing provides professional flat & low-slope roofing in Oshkosh, WI for residential and commercial properties across the Lake Winnebago basin. A low-slope roof is designed for water that falls straight down and then runs to a drain. Beside a lake ten miles wide, a meaningful share of the water does not arrive straight down, and the roof behaves differently than the drawing says it will.
In a hard east wind, water on a flat roof does not simply pond in the low spot. It gets pushed. It piles against the upwind parapet and stands there, against the exact detail that assumed it would only ever see splash. Meanwhile the drain sitting where the tapered layout says the low point is may be several inches out of the water for the duration of the storm.
So we survey the roof for where water actually goes, not only for where it is supposed to. That means looking at stain lines and debris rings on the deck after a blow, checking the coping and cleat on the windward parapet before checking the field, and asking the building owner which wall the ceiling tiles stain under. Those answers are more reliable than a slope reading.
The details that follow from that are ordinary, and they get skipped anyway. Base flashing carried high enough up the upwind wall that a standing head of water cannot reach the termination bar. Coping joints made with concealed splice plates instead of surface sealant. Scuppers sized and set so that when the drain is out of the water, the water still has somewhere to go. Curbs raised wherever a short one sits in the pile.
On residential low-slope, which in this city means porch roofs, additions and the flat backs of older commercial-fronted buildings downtown, the failure is nearly always the tie-in to the wall above rather than the membrane. We price that tie-in as its own line and photograph it before it gets covered.
Recover versus tear-off gets decided with core cuts and a moisture survey, never by eye and never by what the budget would prefer. If the existing assembly is dry we will recover it and tell you exactly what that saves. If two of six cores come back wet, a recover simply buries the problem under a fresh warranty, and we will not sell you that no matter how the numbers look on the day.
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 flat & low-slope roofing
The difference between flat & low-slope roofing that lasts and flat & low-slope roofing 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
