West Allis Roof Pros provides professional chimney flashing in West Allis, WI for residential and commercial properties across Milwaukee and eastern Waukesha counties. Two things about bungalow chimneys here are worth knowing before anyone quotes you. The stack usually comes up on a slope beside a shed dormer, and the flue inside it is very often carrying far less than it was built to carry.
Take the geometry first. A chimney sitting downslope of a dormer collects everything that dormer sheds, and on a stack wider than about thirty inches that water piles against the back face rather than parting around it. The correct answer is a framed saddle behind the stack that splits the flow, sheathed and flashed as a small roof of its own. It is skipped constantly because it costs more than a bead of sealant.
Then the flue. Many of these houses were built for a coal or gravity furnace and now have a sealed combustion appliance venting out a side wall, which leaves an oversized masonry flue serving only a water heater. An oversized flue runs cool, condenses its own exhaust, and takes the mortar apart from the inside, so the brick you see failing at the top is often reporting a heating problem rather than a roofing one.
We will say that out loud and then stop, because relining and appliance venting are not our trade. That work belongs to a licensed heating contractor, and we will tell you to get one out to look before you spend a dollar on masonry above the roof line. Rebuilding a crown over a flue that is still quietly condensing is money you are going to spend a second time.
Where the flashing really is the fault, the repair is sheet metal rather than sealant. New step pieces interleaved with the courses on both sides, a pan across the low side, the saddle behind, and counterflashing in two pieces set into a ground out mortar joint. Nothing in that assembly relies on caulk sticking to a hundred year old brick face.
On the stack itself the right product is a breathable siloxane repellent, and a film forming sealer is the wrong one, because a film traps whatever water is already inside the brick and spalls the face off across a few winters. Where the honest answer involves a mason instead of a roofing crew, we will say it and hand over the photographs for you to take along.
Our licensed and insured team brings the right materials and equipment to every job — a probe cut opened at the rake to count existing roofing layers, 1x8 board sheathing laid with gaps over rafters at 24 inches, a fire-rated soffit board on the setback side of an alley garage, rigid chutes carried up behind a four-foot knee wall, site roll-formed standing seam fed up from the alley apron, a framed saddle set behind a shed dormer to split the flow — and backs the work with a written workmanship warranty. We serve West Allis and nearby communities including Milwaukee, Wauwatosa, Greenfield, Franklin.

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 a probe cut opened at the rake to count existing roofing layers, 1x8 board sheathing laid with gaps over rafters at 24 inches, a fire-rated soffit board on the setback side of an alley garage, rigid chutes carried up behind a four-foot knee wall, 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 West Allis 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 Milwaukee and eastern Waukesha counties means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why West Allis Chooses West Allis Roof Pros
- ✓We open a probe cut at the rake and photograph the layer count before quoting, because West Allis allows two layers and inspects none of them
- ✓We will not install a third layer on any house, and we will tell you plainly that nobody from the city would ever have caught it
- ✓Every estimate names where the container sits and which slopes get worked from a rope, because a lot without a driveway changes the job
- ✓Ventilation chutes go in behind the knee walls while the roof is open, since the finished half story blocks the path the city bulletin assumes
