Commercial Flat Roofing in Madison, WI

The commercial flat roofs we work on around Madison are mostly single-ply membrane, modified bitumen and built-up systems, sitting on retail strips, offices, warehouses and multi-unit residential buildings. Much of the local building stock dates from the same era (the median home here was built in 1979), so a lot of our jobs are full replacement: tear the old roof down to the deck, check the structural condition, then install new insulation and membrane. We also handle repairs and flashing work on roofs with life left in them, and metal roofing where a low-slope section meets a pitched one. Small patch or full tear-off, the approach is the same.

Every project starts on the roof, not at a desk. We walk it, cut core samples, check drains, seams and every penetration, and find out whether the insulation underneath is dry or holding water. You get a written report with photos before anyone talks about a fix. Where a permit is required, we pull it through the City of Madison and manage that paperwork ourselves. Then we schedule around your hours, stage materials to keep loading docks clear, and tear off in sections so the building is never left open overnight. That holds whether the property is downtown or out in Sun Prairie.

Flat roofs rarely fail in the middle of the field. They fail at the details: flashing around HVAC curbs, drain bowls, parapet caps, seams that were never properly welded. Ponding water finds the weak spot and leaks follow. The most common mistake we see is a new membrane laid over wet insulation, which traps the problem and shortens the life of the new roof. Getting it right means fixing drainage, replacing anything saturated, and terminating every edge properly. After installation, regular maintenance keeps small repairs from becoming replacements. Call us for a free estimate on any commercial roof.

Two flat roofs with the same footprint can come back with very different prices, and the gap is usually sitting on the roof already. Before we quote a commercial roof in Madison we walk it, take core cuts, and watch where the water goes. These are the things that move the number.

When you compare bids, make sure they describe the same roof. Each one should name the membrane and its thickness, say whether the old roof comes off or stays, spell out insulation and drainage work, and count the penetrations. A bid that leaves out tear-off or flashing is not cheaper. It is a different job. Call us for an estimate and we will put ours in writing.

Talk to us about a flat roof and you get a straight answer. We walk the roof, check the drains, the flashing, the seams and the parapet caps, and tell you what we find in plain words. If a repair will hold the water back for a few more seasons, we say repair. If the membrane is done, we say replacement, and we show you the spots that make it so. Nobody should buy a roofing system without seeing the reason for it.

During the work, your building stays open. Tenants come and go, deliveries land, and the loading dock stays clear because we stage materials where you tell us to. Every roof opening gets covered before we leave for the day. Water finds any seam left open overnight, so we do not leave one. When something changes mid-job, a soft deck, a rotted curb, a drain that was never tied in, we stop and show you before we touch it. You hear about it from us, not from a stain in the ceiling tiles.

Once the last load leaves, you walk the finished roof with us. We go over the drains, the flashing terminations and the seams together, then hand you a maintenance plan written for that roof: what to check each spring and fall, where debris collects, which penetrations to keep an eye on. Small leaks caught early stay small. Whether the property sits in Madison or out in Sun Prairie, the terms are the same. Call for a free estimate.
