Commercial Roofing in Lake Geneva, WI

Martin Exteriors repairs, replaces and maintains commercial roofs in Lake Geneva, from the shops and restaurants downtown to the lodging along Highway 50. Most of these roofs are flat or low slope, and the work gets scheduled around your busiest weeks. The first visit is a free inspection and estimate. Call (815) 624-6278; the line is staffed 24/7.

Lake Geneva’s Commercial Buildings and Their Roofs

Lake Geneva’s business roofs work hardest when the town is busiest. Downtown, older storefront buildings sit wall to wall with flat roofs, parapets and interior drains. Lodging and event buildings around the lake carry large, complex roofs with low-slope sections tied into steeper ones. Warehouses and metal buildings on the edge of town have long, open roof spans. A leak in July means a closed dining room or an unrentable room, so we look for problems before the season, not during it.

Flat Roof Inspections With a FLIR Thermal Camera and Moisture Meters

Water under a flat roof membrane spreads long before it shows up as a leak inside. We scan commercial flat roofs in Lake Geneva with a high-resolution FLIR i64 thermal camera (640×480) to find wet insulation and hidden moisture, then confirm each spot with a Tramex moisture meter. The detail is fine enough to catch problems that a quick visual walk, or a lower-resolution thermal scan, will miss, and it gives you clear documentation for insurance claims.

Lake Geneva Weather Is Hard on Commercial Roofs

Wind crossing Geneva Lake and the farmland around it reaches a wide, flat roof with nothing in its way. On August 18, 2015, an EF-1 tornado at Lake Geneva caused significant roof damage to four warehouse and metal buildings. On November 10, 2020, winds estimated at 75 mph caused widespread damage in nearby Fontana-on-Geneva-Lake. NOAA counts 17 tornadoes and 67 hail reports in Walworth County from 2010 through 2025. After a storm, ask for a free inspection. We photograph the edges, seams and flashing, since that is where wind damage starts.

Systems We Install and Repair

• TPO, EPDM or PVC membranes on flat and low slope roofs
• Modified bitumen, patched or torn off and replaced
• Restoration coatings when an older membrane is still sound
• Metal roofs on commercial buildings: see our Lake Geneva metal roofing page

The membranes are compared on our TPO and flat roofing page. On the roof, we name the system you have now and the one we would put on next.

Finding Water Before It Shows Inside

On a flat roof, water can travel under the membrane and soak the insulation far from where it drips. A Teledyne FLIR i64 thermal camera shows where insulation is holding water, a Tramex Roofing Inspector Kit confirms each spot, and nothing gets cut open to find it. The thermal images and meter readings go in your report. See what a visit covers on commercial roof repair and maintenance.

Repair, Maintenance or a New Roof

An open seam, a failed boot or worn flashing is a repair. If the insulation is wet over a big area, or the membrane has simply worn out, it is time to replace it. Maintenance plans come in three tiers, starting with drain cleanouts and a written report and going up to repairs, replacement planning and a moisture survey. For seasonal businesses, a spring visit before Memorial Day and a fall visit after the season are often enough to keep a roof out of the summer schedule.

Recent Commercial Roofing Work

On multi-building properties, timing matters. We re-roofed all nine buildings of a condo association the same day, so residents dealt with tear-off noise once instead of over many days. On a church campus, our crew re-shingled two buildings with the goal of a finished roof for Sunday services. Project videos: the condo association and the church campus.

Scheduling Around the Lake Geneva Season

US 12, Highway 50 and Highway 120 bring our crews from Roscoe to downtown and around the lake. Tear-off and other loud work is timed around your hours, events and guests.

Lake Geneva Commercial Roofing FAQ

Can you work around the summer season in Lake Geneva?

Yes. Loud work like tear-off is timed around your hours, events and guests, and many seasonal businesses book maintenance in spring or fall so the roof stays out of the busy months.

Do you work on restaurant, lodging and shop roofs downtown?

Yes. Most downtown and lakeside business roofs here are flat or low slope, and we repair and replace TPO, EPDM, PVC and modified bitumen on them.

Our building had storm damage. What should we do first?

Call (815) 624-6278. Someone answers 24/7. We’ll set up a free inspection, walk the roof and photograph the edges, seams and flashing where wind damage starts.

How far is Lake Geneva from your office?

About an hour from 11704 Main St, Roscoe, IL 61073, by US 12 or Highway 50.

Is the inspection free?

Yes. Both the inspection and the estimate cost nothing, and we photograph what we find.
