Roof Coating Restoration in Kenosha, WI

Findings That Qualify a Roof for Coating

Five findings must line up before we recommend a coating. The membrane must be intact, with no widespread cracking, shrinkage or open laps. The insulation must test dry across the field, confirmed by an infrared scan and core cuts at the suspect spots. The deck must be sound, and the existing system must accept the coating without a chemical reaction. Drainage must work, because standing water is hard on most coatings.

Each finding is recorded with a photograph, a measurement or a meter reading. The recorded set is the baseline report. If any one of the five fails, we state which, and we explain whether a repair would bring the roof back into range or whether the roof has moved past the point where a coating helps.

A finding that fails is not a dead end. A roof with isolated wet areas can often be repaired by cutting out the wet insulation, replacing it and re-testing, and the roof then returns to the qualifying list. The file shows both states, before and after, so the decision is traceable.

Adhesion Tests, Core Cuts and Moisture Surveys

A coating is only as good as its bond. We clean a test patch, apply the proposed coating, let it cure and then pull it. The result goes into the file with a photo of the patch. Poor adhesion means the surface needs different preparation or a different coating, and sometimes it means the roof is a poor candidate.

The moisture survey comes first because it decides whether the test patch is worth doing. A scan across the full roof marks cool, wet areas, and core cuts confirm what the scan suggests. Wet areas are cut out and replaced before any coating goes down. Coating over wet insulation traps the water, and the blisters that follow can be seen from the ground a season later.

Coating Chemistries and Where Each Fits

Acrylic, silicone and other liquid-applied systems behave differently. Acrylic coatings are common on many surfaces, but they can suffer where water stands. Silicone coatings tolerate ponding better and bond to a range of membranes, though dirt can pick up on the surface and some existing surfaces need a primer.

The choice depends on the existing membrane, the drainage and the exposure. A roof with chronic ponding that cannot be corrected may favor silicone. A well-drained roof with a reflective goal may do well with acrylic. We name the system type in the scope and describe the cure and recoat intervals in plain terms.

Application Windows in a Lakeshore Climate

Coatings cure in dry weather, above a minimum temperature, and with no rain forecast for a set period. Kenosha has a short window for that. Precipitation runs about 37.6 inches a year, and lakefront buildings along Kenosha County's roughly 8 miles of Lake Michigan shoreline take extra wind off the water. We schedule coating work for the summer and early autumn, and we monitor the forecast on each application day.

Application is done in stages so no part of the roof is left half-finished when weather arrives. Seams and flashings are prepared and reinforced first, then the field coat goes on, then the second coat. The dated photo set records each stage, and we keep the thickness measurements with it.

Winter sets the outer limit. Snow totals near 36.2 inches a year and a January 1985 low of minus 31 degrees describe what a cured coating has to survive. A coating applied late in the season may not cure fully before the first freeze, and an incomplete cure shows up as peeling at the seams the following spring. When the calendar is tight, we recommend waiting.

Where Coating Fits Across Kenosha Building Types

Coatings suit roofs where tear-off would be disruptive or costly and the existing roof is still sound. A distribution building in a park such as Pleasant Prairie's LakeView Corporate Park may not be able to pause shipping, and a coating goes on with little disruption below if the roof qualifies. A hospital roof may favor a coating when odors and noise must be minimized, subject to the access rules.

Not every roof qualifies. A building that has had a recover over a wet roof, or a roof with multiple prior repairs that have failed, may be a replacement candidate. The report says which category applies. When a coating is not right, we point to a recover or replacement and give the reasoning from the file.

Plants in Racine County and the manufacturing buildings around Racine add a further test. Process exhaust and heat can leave residue on a membrane, and the cleaning step has to remove it before any coating can bond. We photograph the residue, record the cleaner used and run the adhesion patch in the worst-affected area, so the test represents the hardest condition on the roof.

Warranty Files and the Close-Out Package

A coating system can carry a manufacturer warranty when the substrate, the preparation and the application meet the manufacturer's terms. We read those terms before we propose the work and record how each requirement is met. Thickness readings, batch numbers, cure times and weather on the application days all go into the warranty file.

The close-out package holds the baseline report, the test results, the application log and the photo sets from before, during and after. It also states the recoat interval the system calls for and the inspection schedule we suggest. The facility director can attach the file to a capital request and use it again when the next decision arrives. A roof with a coating on it still needs preventive maintenance, and the file explains which parts of the schedule matter most.
