When we got 14 inches of wet snow followed by a freeze in St. Paul, our parapet scuppers froze solid and water started ponding 5 inches deep over our anchor tenant. Their winter crew came out the same afternoon with low-pressure steam equipment, cleared the drains and scuppers without puncturing the PVC membrane, and set up our semi-annual maintenance plan.
Our 36-unit building in St. Paul took 1.75-inch hail last summer and the insurance company's first out-of-state adjuster tried to claim it was 'cosmetic.' St. Paul Commercial Roofers's HAAG-certified inspector met the second adjuster on the roof with chalk grids, core cuts, and dented metal copings. Claim was approved in full for $218k and the crew finished the entire replacement in 6 days.
Ice dams along the north eave of our facility in St. Paul were backing water under the oldlap seams every February. St. Paul Commercial Roofers retrofitted 24-gauge Kynar 500 standing seam panels with high-temp ice and water shield and heavy-duty snow retention bars. Not a single icicle or drip all winter.
After the last hail and wind storm came through Ramsey County, our 22-year-old ballasted roof in Midway Industrial District had water dripping near two electrical panels. St. Paul Commercial Roofers tarped the active leaks within 2 hours of our call, documented the core cuts and thermal imaging for our commercial insurer, and installed a mechanically attached 60-mil white TPO system with staggered R-30 polyiso insulation. Passed both the manufacturer 20-year NDL walk-through and St. Paul Department of Safety and Inspections (DSI, 375 Jackson St) final inspection with zero punch-list items.
Our metal and mod-bit warehouse roof in St. Paul still had dry insulation underneath, which their crew proved with core samples instead of pushing an expensive tear-off. They power-washed the entire deck, reinforced every seam and fastener with fabric-embedded mastic, and sprayed a white high-solids silicone coating with a 15-year warranty. Our upper-level warehouse temps dropped almost 10 degrees in July.
We manage a 3-story medical/office building off I-94 in St. Paul and had a stubborn leak every time snow melted on the flat roof. Two other companies just smeared mastic around the drain and charged us $900. St. Paul Commercial Roofers brought an infrared moisture scanner, traced the water under the membrane to a cracked RTU pitch pocket 18 feet away, heat-welded new reinforced curb flashing, and gave us before-and-after photos. Dry as a bone ever since.

Whenever a low-slope commercial roof replacement in St. Paul exposes the structural deck, Minnesota Rules Chapter 1323 (Climate Zone 6A) requires R-30ci continuous insulation installed above the deck—typically two staggered layers of 2.6-inch polyisocyanurate (5.2 inches total)—along with positive 1/4-inch-per-foot drainage approved by St. Paul Department of Safety and Inspections (DSI, 375 Jackson St).
Each system excels in specific St. Paul applications: 60-to-80 mil white TPO offers heat-welded seams and lower cooling loads for warehouses in Midway Industrial District, Energy Park, Westgate Business Park, Riverview Industrial Park (West Side Flats), Downtown Lowertown & Skyway Core, Red Rock Industrial District, Empire Builder Industrial Park; 60-to-90 mil EPDM provides unmatched -45°F sub-zero elasticity and hail bruise resistance; and DuPont Elvaloy KEE-PVC is mandatory for St. Paul restaurants and manufacturing plants with rooftop grease or chemical exhaust.
In St. Paul and Ramsey County, fluid-applied silicone roof coatings average $4.25–$6.75/sq ft; single-ply fleece-back recovers over dry existing assemblies range from $6.50–$9.50/sq ft; and full tear-offs with code-mandated R-30ci polyiso, gypsum cover boards, and 60-to-80 mil TPO/EPDM/PVC membranes range from $10.50–$16.50/sq ft depending on deck height and RTU density.
The Minnesota State Building Code allows a commercial roof recover only if there is currently just one (1) existing roof layer on the building and forensic infrared/core testing proves the underlying insulation and structural deck are dry. If the building in St. Paul already has two roof layers or saturated insulation, St. Paul Department of Safety and Inspections (DSI, 375 Jackson St) mandates a complete tear-off.
We eliminate 48-hour ponding water across Midway Industrial District, Energy Park, Westgate Business Park, Riverview Industrial Park (West Side Flats), Downtown Lowertown & Skyway Core, Red Rock Industrial District, Empire Builder Industrial Park by installing CAD-engineered 1/4-inch-per-foot tapered polyiso insulation, 1/2-inch-per-foot upslope RTU crickets, recessed 8'x8' cast-iron drain sumps, code-required secondary overflow scuppers, and UL-listed self-regulating heat trace cables.
Hail damage on low-slope TPO, PVC, EPDM, and modified bitumen roofs in St. Paul is rarely visible from the ground; large hailstones crush the polyiso core beneath the membrane and fracture the reinforcing scrim on the underside of the sheet first. Our HAAG-certified inspectors perform non-invasive infrared scans and documented core tests to prove storm losses within Minnesota's 2-year claim window.
A standard material warranty only reimburses the prorated cost of defective membrane rolls and excludes labor. A Full-System No-Dollar-Limit (NDL) warranty—issued after a factory engineer inspects our work in St. Paul—covers 100% of both labor and materials to repair any covered leak for 20, 25, or 30 years with zero dollar cap.
Yes! We operate 24/7 emergency winter leak and snow/ice response crews along I-94, I-35E, US-52 (Lafayette Fwy), MN-280, University Ave, Snelling Ave (MN-51), West 7th St (MN-5), Shepard Rd throughout Ramsey County. We use low-pressure 290°F commercial steam units to remove ice dams and thaw frozen drains without puncturing cold-brittle membranes, and apply catalyzed PMMA and sub-zero urethanes rated down to -15°F.
No. We coordinate crane lifts during early-morning or off-peak windows in Midway Industrial District, Energy Park, Westgate Business Park, Riverview Industrial Park (West Side Flats), Downtown Lowertown & Skyway Core, Red Rock Industrial District, Empire Builder Industrial Park, utilize zero-VOC odorless adhesives above occupied offices and medical clinics, install underside poly dust containment over warehouse racking, and complete 100% watertight night-seals at the end of every shift.
Yes! Under Internal Revenue Code Section 179(e), nonresidential commercial roof replacements in St. Paul qualify for immediate first-year Section 179 tax deduction (up to annual federal dollar limits) rather than 39-year straight-line depreciation, while fluid-applied coatings and repairs often qualify as 100% current-year operating maintenance.
