West Allis Roof Pros provides professional flat & low-slope roofing in West Allis, WI for residential and commercial properties across Milwaukee and eastern Waukesha counties. Most low-slope work in this city is small and close to a property line. Alley garages with nearly flat decks, back additions, porch roofs and storefronts along Greenfield or National Avenue. The membrane question is easy. The edge question is not, and it decides the detailing.
The zoning rules put a detached garage three feet from a side or rear lot line, with a maximum two foot overhang allowed into that setback, and five feet off the alley. Do the arithmetic and the drip edge on a legally sited garage can end up within a foot of somebody else's yard. Everything that leaves that roof, water and ice and debris, leaves it onto ground you do not own.
That changes the design rather than the product. We terminate the low side into a gutter with a real outlet instead of letting a membrane sheet water over an open edge onto somebody's lawn, we run the discharge toward the alley apron where the grade already carries it, and we detail the two close sides so nothing sheds toward the neighboring lot at all.
On the membrane itself we keep it simple and durable. Fully adhered EPDM on most garage decks, sixty mil TPO where a lighter surface is wanted, and two ply modified bitumen where somebody actually walks on the roof to reach a rooftop unit. Fastener and plate spacing gets tightened at the perimeter and corners, which is where a small roof in an open alley actually fails.
Before we recover anything we open it up. A test cut straight through the assembly answers whether the insulation underneath is dry and whether you are already carrying two layers, and both of those answers change the price by a lot. On garages we usually find a torch down membrane laid over an original rolled roofing that nobody currently alive remembers installing, which settles the question immediately.
Ponding gets fixed rather than merely noted in a report. Anything still holding standing water two days after rain gets tapered insulation or a relocated outlet, and if you would rather wait a year we write the depth down and date it so the decision is documented and yours. On a garage deck the water sits directly over your car, which tends to settle the conversation quickly.
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 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 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
