Commercial Lightning Protection in Winona, MN

With 74% of homes predating 1980 and 40% before 1940, Winona has older downtown buildings, and tall brick fronts and parapets are worth assessing for strike exposure. Utility gas heats about 63% of Winona homes, and rooftop gas units and gas piping on commercial buildings are bonded to the lightning system as part of the design.

Permits, utility and drive time in Winona
Commercial lightning protection is built to NFPA 780 and UL 96A, and any bonding to the building's electrical grounding system under NEC 250 is electrical work handled through the Minnesota Department of Labor and Industry. Winona has adopted the Minnesota State Building Code, so roof attachments or structural work on a commercial building may need a city building permit, while electrical bonding goes through DLI.
Winona is about 39 minutes away, 24 road miles from our Holmen shop via WI 35 and WI 54 across the Mississippi into Winona on MN 43. The Minnesota PUC service-area map places Winona with Xcel Energy. We coordinate any disconnect, meter or interconnection step with them.
Working with membrane and metal roofs
Flat commercial roofs use membrane, built-up or metal systems, and each needs its own attachment method. We use bases and adhesives made for the roof type and avoid unnecessary penetrations. If your roof is under a roofer's or manufacturer's coverage, we coordinate before we touch it, and we recommend doing lightning work during re-roofing when access is easiest. A walk-through with the roofer prevents leaks and keeps responsibility clear. Bring your roofing contract.
Inspection and maintenance of systems
Commercial lightning systems age. Roof work, additions and rooftop equipment changes often cut or move conductors, and connections loosen with freeze and thaw. We inspect terminals, conductors and grounds, test ground resistance and report what needs repair. After any strike or major roof project, a check confirms the path is intact. Keep a record of inspections with your building file, since insurers and future buyers may ask for it. We also leave a labeled map of the grounds.
Winter snow, ice and short days limit roof access, which is why fall is a common window to complete commercial roof-level installation.
