Flat and low-slope roofing systems for commercial buildings — installed, repaired, and maintained with minimal disruption to your business.
Free inspection · Written estimate · No obligation
Commercial roofs fail differently than residential roofs. Ponding water, failed seams, flashing separations at rooftop units, and neglected maintenance cause most commercial leaks — not shingle age. We install and service the flat and low-slope membrane systems that Brown County commercial buildings depend on.
We schedule work around your operations, stage materials to keep entries and docks clear, and document everything — before photos, during, and after — so facility managers and owners always know the condition of their roof asset.
Every job is a complete system — materials, flashing, ventilation, and warranty — not a surface patch.
Complete membrane systems for new construction and full replacements, specified for Wisconsin snow loads and drainage.
Leak tracing, seam repair, flashing rebuilds at curbs and units, and puncture repair with documented findings.
Scheduled inspections, debris and drain clearing, and minor repairs before they become interior damage.
Condition reports with photos and remaining-life estimates for buyers, sellers, and property managers.
Tapered insulation design, drain and scupper service, and ponding remediation that extends membrane life.
Rapid temporary protection and permanent repair scheduling when a commercial roof is actively leaking.
We inspect the membrane, seams, flashing, drainage, and rooftop penetrations, and core-sample where age or layers are unknown.
Clear scope with staging, schedule, and business-continuity measures — entries, docks, and tenant operations protected.
Crews work in phases to keep the building dry every night, with daily cleanup and progress reporting.
Seam checks, flashing verification, and drain testing before sign-off.
Complete photo record, warranty registration, and a maintenance schedule for the building file.
Standing water accelerates membrane breakdown and voids many manufacturer warranties.
Membrane movement and seam failure are the leading commercial leak sources we repair.
Flashing separations around HVAC and vents cause most interior commercial water damage.
Saturated insulation loses R-value fast — a thermal symptom of a roofing problem, not an HVAC problem.
Unknown age plus no maintenance history is the highest-risk combination in commercial roofing.
From Green Bay to the Northwoods, our crews install and repair roofs across the region.
We phase work, protect entries and docks, schedule noisy operations around your hours, and keep the building watertight every night. You get a written phasing plan before we start.
It depends on membrane condition, insulation saturation, and remaining life. We core-test and document, then show you the math for both paths — including phased replacement where appropriate.
