Dubuque Premium Roofing provides professional chimney flashing in Dubuque, IA for residential and commercial properties across Dubuque County and the Driftless. Cut a reglet into a limestone chimney and you will regret it. A great many chimneys and gable walls here are random-rubble dolomite laid in soft lime mortar, with no coursing to follow and nothing that holds a saw kerf. So we flash them differently.
The method on rubble stone is a surface-mounted counterflashing: a formed copper or coated-steel apron set against the face, terminated with a mechanically fastened bar and a compatible sealant, with the fasteners landing in stone rather than in mortar joints. It is less elegant than a let-in reglet and it is the detail that survives on this masonry. On coursed brick we do cut a proper reglet, because there the joint is there for it.
Underneath the counterflashing the step flashing does the actual work, one piece per course, woven into the covering and never a continuous strip of anything. Continuous flashing against a chimney is the single most common failure we open up, usually a length of aluminum bedded in roof cement by somebody who was in a hurry. It works for two winters.
Crickets are not optional above a certain width. Any chimney more than about thirty inches across the upslope face gets a framed saddle, and on the steep planes common here that saddle is a real piece of framing rather than a token bump. Without it, snow and debris pile against the upslope side and sit there through a Dubuque February, which is how the mortar got soft in the first place.
The masonry itself frequently needs attention before flashing is worth doing. Nineteenth-century stacks here are tall, often unlined, and repointed at some point with a hard portland mix that traps moisture in softer stone and spalls it. Repointing in a lime mortar compatible with the original is the right repair, and we will say so even though it usually means bringing in a mason rather than us.
If your chimney is unused, decommissioning it is worth pricing next to repairing it. Taking a redundant stack down below the roof line and framing over it removes a permanent leak path, a maintenance item and a load on old framing. In a historic district that change is reviewable, so we check before recommending it. A chimney nobody uses is still a chimney somebody has to flash.
Our licensed and insured team brings the right materials and equipment to every job — self-adhered ice barrier past the wall line, copper step and pan flashing, surface-mounted counterflashing with termination bar, salvaged natural slate and copper hooks, standing-seam snow retention rails, slate ripper and hook re-hanging — and backs the work with a written workmanship warranty. We serve Dubuque and nearby communities including Asbury, Dyersville, Cascade, Epworth.

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 self-adhered ice barrier past the wall line, copper step and pan flashing, surface-mounted counterflashing with termination bar, salvaged natural slate and copper hooks, 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 Dubuque 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 Dubuque County and the Driftless means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Dubuque Chooses Dubuque Premium Roofing
- ✓We survey the lot before the roof. On a bluff property, staging and debris handling decide the price more than the covering ever will, so we quote it visibly.
- ✓We identify what is actually on a pre-war house before scoping it. Slate, clay tile and cedar under later layers all lead somewhere different from asphalt.
- ✓We know the Historic Preservation Commission's design review calendar for the five local districts, so a material application does not stall your project by a month.
- ✓We will argue you down. A sound slate roof losing a few pieces a year needs flashing and rehanging, not a tear-off, and we say so before quoting.
The standards behind chimney flashing
Quality here is not a matter of opinion — it is written down. The chimney flashing work we do in Dubuque 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.
