PVC Roofing in Kenosha, WI

Welded Seams and Flashing Details

PVC sheets are joined by hot-air welding, and the welded seam becomes as strong as the sheet when it is made on a clean, dry surface. Prefabricated corners and pipe boots are welded in the same way. Our probe check runs along a sample of each seam type and each flashing, and every open length is marked on the roof plan with a number.

Flashings take the most abuse. Walls, curbs and penetrations hold the sheet in place while it moves with temperature, so we check termination bars, sealant and corner welds first. The photo set from each visit shows whether a detail is stable or opening further.

Penetrations get the same treatment. Pipe boots, conduit supports, drain bodies and curb corners are all places where sheet has been cut and re-joined, so each is a possible leak path. We count them, rate them and flag any boot that is cracked, loose or sealed with surface caulk alone. A short table of penetrations by type and condition shows the owner which details are due for work before the next winter.

Grease, Oil and Chemical Exposure

PVC is often chosen where the roof sees kitchen exhaust, oils or chemical residue, because the membrane tolerates those exposures better than several other single-ply types. That does not make the surface maintenance-free. Grease collects near fans and drains, hides seam defects and makes walking unsafe.

We record where exhaust discharges onto the roof, the extent of staining and whether grease traps and fan curbs are doing their job. Where a Racine County plant or a food service building carries a PVC roof, that exposure map becomes part of the roof condition report and guides the cleaning interval.

Cold-Weather Behavior and Winter Findings

PVC stiffens in cold weather, and a roof that has gone through a Kenosha winter shows its weak points in March. The January 1979 blizzard dropped about 19 inches and the 2011 Groundhog Day blizzard about 23.2 inches of snow, reminders that a drift can sit against a parapet for weeks. Snow and ice that melt and refreeze along a wall can lift a termination or crack a brittle weld.

After the thaw we walk the perimeter and rate each wall flashing. Findings are dated and sorted into items that need water control now and items that can wait for the spring work order. The result is a short list a facility team can act on, supported by photographs.

Winter access matters as well. A roof under snow cannot be inspected, so we schedule the main walk for early spring and a shorter check in late fall, before the first lasting snow. Between visits, a facility team can photograph drains and parapets after a storm and send the images to us, and those images go into the same log so the dated record has no gaps.

Moisture Under a Sound-Looking Sheet

A PVC sheet can look intact while the insulation beneath it holds water. Leaks that enter at a flashing travel along the deck before they show inside, so a ceiling stain may sit far from the opening. An infrared moisture survey maps the cooler, wetter areas, and a core cut confirms what the insulation holds.

We record the survey map, the core location and the moisture reading, then give the area a condition rating. If wet insulation covers a small area, targeted removal may be enough. If it spreads, the finding supports a larger capital request and the record shows why.

Timing the survey matters. Infrared works best on a clear evening after a sunny day, when wet insulation holds heat longer than dry board. We schedule it for that window, not for the first convenient date, and we record the weather on the day so a later survey can be compared fairly with this one.

PVC on Large Buildings in the Corridor

Amazon, Rust-Oleum, Uline and Associated Wholesale Grocers all have warehouses or distribution centers in Kenosha, and LakeView Corporate Park in Pleasant Prairie is described by the village as the largest industrial park in Wisconsin. A building in that mix may carry PVC, and the first visit confirms the system on each roof.

On a manufacturing plant roof or a warehouse, we check the same items: seams, flashings, drains, rooftop equipment curbs and any area where process exhaust reaches the sheet. The log makes it easy to compare buildings in a portfolio, whether they sit in Pleasant Prairie, in Racine County or in the Kenosha business parks.

Racine County's manufacturers, among them Case IH, Dremel and Modine, cover a wide range of work, and wherever a plant puts heat, steam or exhaust onto its roof, that exposure gets its own line in the register. A facility director can then see which buildings need a shorter inspection interval.

Repair Options and When Replacement Is Priced

PVC repairs are welded, which makes them part of the sheet if the surface is clean. Aged sheet that has lost plasticizer becomes harder to weld, and repeated failures in one area point toward replacement. We price repair and replacement against the same scope version so the capital request is easy to compare.

The alternatives matter too. A KEE membrane may suit a roof with heavy oil exposure, while a TPO sheet may suit a roof with little contamination and a tighter budget. The inspection findings decide which is worth pricing.
