Duluth Roof Pros provides professional chimney flashing in Duluth, MN for residential and commercial properties across northeastern Minnesota. Chimney flashing is the most common real leak we find in this city, and it is nearly always the same three mistakes. A surface-mounted counterflashing held on with sealant, no cricket behind a wide stack, and step flashing that was reused from the previous roof.
Sealant is a maintenance product with a service life of a few years, and it is holding a joint on the most exposed masonry on the house. On a windward elevation, with driven rain arriving horizontally for six or eight hours, that joint gets tested harder than anything else on the roof. Counterflashing belongs in a reglet cut into the mortar joint, folded, set, and only then pointed, so the water path is mechanical rather than adhesive.
The cricket is the part people argue about and it is not optional. Measure the stack across the slope; past roughly two and a half feet it wants a saddle upslope of it, framed and sheathed as roof rather than patched in metal, because that face otherwise becomes a dam. In Duluth the dam fills with snow, holds it against the masonry through a long winter, and feeds meltwater straight to the joint least able to cope.
Step flashing is per-course, formed, and new. It cannot be reused, it cannot be replaced with a continuous strip of metal up the side of the stack, and it has to be woven into the shingle courses rather than laid over them. Where a chimney meets a sidewall, a kick-out at the bottom is what stops water running behind the siding, and its absence explains a startling number of rotted wall cavities.
We look at the masonry as well, since no flashing detail will save a stack that is taking water through a cracked crown or open bed joints. Where the brick is spalled or the crown is cracked we say so and refer it out, since that is masonry work and we would rather it were done by someone who does it every day.
Above the roofline, we check that the flue extends far enough above the ridge for draft on a windy hillside site, and we mention it if it does not. Chimney work is quoted separately from the roof so you can see what the stack is costing you, and so you can defer it if the roof cannot wait.
Our insured and bonded team brings the right materials and equipment to every job — windward-plane six-nail fastening, starter strip run along the rakes, hemmed edge metal at close fastener spacing, ASTM D7158 Class H field-of-roof ratings, ASCE 7 escarpment speed-up factors, ASCE 7 exposure categories B through D — and backs the work with a written workmanship warranty. We serve Duluth and nearby communities including Hermantown, Proctor, Rice Lake, Esko.

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 windward-plane six-nail fastening, starter strip run along the rakes, hemmed edge metal at close fastener spacing, ASTM D7158 Class H field-of-roof ratings, 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 Duluth 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 northeastern Minnesota means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Duluth Chooses Duluth Roof Pros
- ✓Every proposal carries an exposure zone before it carries a price: where the house sits on the hillside, which planes face Lake Superior, and what stands upwind of each one.
- ✓Condition and damage are recorded by elevation and never averaged across a roof, because our lake-facing and hill-facing slopes routinely age years apart on the same house.
- ✓Perimeter before product. We would rather spend your money on starter along the rakes and hemmed edge metal than on a premium field shingle sitting above a bare edge.
- ✓We name the sheltered planes on your own house and specify them down, so nobody buys a crest-lot roof for a lower-hillside lot.
The standards behind chimney flashing
Quality here is not a matter of opinion — it is written down. The chimney flashing work we do in Duluth 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.
