Bismarck Roof Pros provides professional chimney flashing in Bismarck, ND for residential and commercial properties across central North Dakota. A masonry chimney barely moves. The metal flashed against it moves a great deal, all year, in both directions. That mismatch, repeated across a 159-degree range, is the reason the chimney is the leak you have already paid to fix three times and still have.
Brick and mortar have a very low coefficient of expansion and enormous mass, so the stack sits essentially still through the year. The step flashing woven into the shingle courses beside it is thin steel doing the full travel of the roof. Anything that rigidly bonds those two surfaces together is being asked to absorb the difference, and eventually it stops absorbing and starts tearing.
That is exactly what surface-mounted counterflashing sealed with mastic does. It is quick, it looks finished from the driveway, and in a mild market it lasts a respectable number of years. Here it typically gives up in three or four seasons, and the failure is invisible from the ground because the bead is still sitting there. It simply is not bonded to anything anymore.
We cut a reglet instead. A saw kerf into the mortar joint, counterflashing folded and set into that kerf, wedged and then pointed, lapping down over the step flashing without ever being fastened to it. The step flashing is left free to slide behind the counterflashing as the roof travels through the year, which is the entire point of the detail and the only version of it we have seen survive here long-term.
A stack more than roughly thirty inches across gets a saddle on its up-slope side, framed and metal-clad rather than simply shingled flat. Snow and ice sit against a flat back wall for months at a time in central North Dakota, and a saddle that sheds that load is a great deal cheaper than the deck and framing repair that follows when it does not.
We also look at the crown while we are up there, along with the chase cover on factory-built units and the storm collar on the flue. Those three fail quietly, get blamed on the flashing, and account for a surprising share of the chimney leaks we are called out to. A chase cover with a standing seam and a proper drip edge is a twenty-year part rather than a five-year one.
Our insured and bonded team brings the right materials and equipment to every job — floating-clip standing seam with one defined fixed point, SBS polymer-modified shingle mat, ring-shank roofing nails in a six-nail common bond, a sawn mortar reglet that lets step flashing slide, published low-temperature flexibility of roofing sealant, hemmed and cleated drip edge in ten-foot lengths — and backs the work with a written workmanship warranty. We serve Bismarck and nearby communities including Mandan, Lincoln, Wilton, New Salem.

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 floating-clip standing seam with one defined fixed point, SBS polymer-modified shingle mat, ring-shank roofing nails in a six-nail common bond, a sawn mortar reglet that lets step flashing slide, 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 Bismarck 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 central North Dakota means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Bismarck Chooses Bismarck Roof Pros
- ✓We specify for a 159-degree annual range rather than for one season, which changes the nail, the underlayment and the flashing detail
- ✓SBS polymer-modified shingles recommended over plain impact-rated laminate, because rating tests are run at room temperature
- ✓Floating-clip standing seam only on houses; we will argue against exposed-fastener panel and put the reasoning in writing
- ✓Counterflashing set into a cut reglet instead of surface-mounted in mastic, so step flashing stays free to move

If a contractor cannot tell you which standard a detail comes from, that is worth asking about before you sign.
