Madison WI Roof Pros provides professional flat & low-slope roofing in Madison, WI for residential and commercial properties across Dane County. Low-slope roofing here splits along the same line everything else on this site does. Some of it sits on genuine commercial buildings. A great deal of it sits on the flat-topped apartment stock and on the rear additions of houses long since cut into flats.
That second category is where the code question bites. A rear porch roof on a duplex is dwelling work. The same detail on a building cut into three or more flats is not, because Wisconsin's dwelling code stops at two units and a building of three or more without the specified separations is a commercial building under chs. SPS 361 to 366. The membrane is identical. The permit path is not.
Technically the work is straightforward when it is done properly. Heat-welded single-ply over an insulated deck, seams welded and probed rather than taped, positive slope to a drain or a scupper that actually discharges somewhere useful, and terminations tied into wall flashing rather than smeared with sealant and hoped over. Sealant is a detail, not a termination, and treating it as one is why these roofs get replaced early.
Recover versus tear-off is the decision that costs money either way, so we take a core cut and hand you the plug. If the insulation is dry and the existing membrane is sound, a recover is legitimate and cheaper. If the core comes out wet, a recover buries the water and you pay for the same roof twice. We do not propose one without the other.
Ponding is the complaint we hear most and the one owners most often accept as normal. It is not normal. Water still standing forty-eight hours after rain means the slope or the drainage is wrong, and no membrane is warranted to sit under a pond indefinitely. Tapered insulation, a relocated drain or a new scupper fixes the cause instead of chasing seam failures forever.
On tenanted buildings the sequencing matters as much as the detailing. We phase work so units stay occupied and rent keeps arriving, we keep the roof watertight at the end of each day rather than tarped over an open deck, and we schedule noisy work around the hours an owner is willing to defend to their tenants. Owners accept ponding because somebody once told them flat roofs pond. They do not have to.
Our licensed and insured team brings the right materials and equipment to every job — a written unit-count and code-path determination, self-adhered ice barrier run past the interior wall line, six nails per shingle set in the double nailing zone, aluminum drip edge lapped over the ice barrier at the rake, closed-cut valleys shingled from the larger slope first, heat-welded single-ply on rear porch and dormer decks — and backs the work with a written workmanship warranty. We serve Madison and nearby communities including Sun Prairie, Fitchburg, Middleton, Verona.

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 written unit-count and code-path determination, self-adhered ice barrier run past the interior wall line, six nails per shingle set in the double nailing zone, aluminum drip edge lapped over the ice barrier at the rake, 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 Madison 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 Dane County means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Madison Chooses Madison WI Roof Pros
- ✓We settle who owns the building and how many dwelling units are under the roof before we price anything, because in this city that single answer moves the code, the permit and the product all at once.
- ✓An owner who lives in the house may pull their own reroof permit here. A landlord may not, and we put that in writing at the bid rather than letting it surface at the permit counter.
- ✓At three dwelling units your house stops being a house in code terms and becomes a commercial building under chs. SPS 361 to 366. We say so before you collect three residential bids that cannot be permitted.
- ✓Interior and attic access on tenanted buildings is booked around the written advance notice Wisconsin owes an occupant, so no inspection gets refused at the door and no visit is wasted.
