Silicone Roof Coatings, Flashing Repair & Leak Prevention for Chicago Commercial Roofs Built for Snow and Ice
Commercial Roof Coating & Restoration Contractors in Chicago, IL
Chicago commercial roofs face two very different seasons, and both are hard on them. In winter, snow piles up on flat roofs, drifts against parapets and rooftop units, and melts and refreezes for weeks. Ice backs up behind clogged drains and works its way under seams and flashings. In summer, the same roof bakes in the sun on humid 90-degree days. That swing from bitter cold to intense heat makes roofing materials expand and contract over and over, until seams split, flashings pull loose and the membrane cracks.
Replacing a worn roof is expensive and disruptive, but many Chicago roofs do not need replacement yet. Presto Restoration has more than 25 years of experience restoring commercial roofs with high-performance coating systems. We repair the damage, renew the flashings and seal the roof with a seamless coating that sheds water and reflects summer heat. For warehouses near O’Hare, mid-rise offices in the West Loop or flat-roof apartment buildings across the city, restoration can add many years of service at a fraction of the cost of tearing off the roof.
OUR COMMERCIAL ROOF COATING SERVICES IN CHICAGO
We restore every common commercial roof type in the Chicago area with coating systems chosen for heavy snow, freeze-thaw cycling and summer heat.
Silicone is one of the best choices for Chicago flat roofs because it handles standing water better than most coatings. Snowmelt often ponds near drains and low spots for days, and silicone does not soften or break down when it stays wet. It also stays flexible in deep cold, so it does not crack when temperatures fall below zero. We clean the roof, repair seams and damaged areas, and apply silicone in a single seamless layer at the thickness the warranty requires. The bright white finish reflects summer sun and helps lower cooling costs.
Single-ply roofs such as TPO, PVC and EPDM are common on Chicago commercial buildings. As they age, their seams loosen and the membrane shrinks, especially after many winters of extreme cold. We clean and prepare the membrane, reinforce seams and flashings, and apply a compatible coating that seals the whole surface. This gives an aging single-ply roof a new watertight layer without removing the existing system, which saves money and keeps the building in service.
Spray polyurethane foam roofs insulate well and shed water, but only while their protective top coat is intact. Once sun and weather wear that coat away, the foam underneath starts to break down and absorb water, which can freeze and damage it further. We inspect the foam, repair damaged or wet areas, and apply a fresh top coat to protect it from UV and moisture. Regular recoating keeps an SPF roof working well for decades in the Chicago climate.
Built-up roofs, modified bitumen and cap sheet systems remain common on older Chicago buildings. Over time their surfaces dry out, crack and lose granules, and freeze-thaw cycles open blisters and seams. We repair blisters and splits, reinforce seams and flashings, and apply a coating system that bonds to the asphalt surface. The coating seals out water, reflects heat and slows the aging of the roof below it.
A coating is not the right answer for every roof. If too much of the roof insulation is wet, or the deck below has been damaged, replacement may be the better choice. That is why we start by checking the roof with moisture testing and core samples. If the roof is a good candidate, we lay out the restoration plan and cost. If not, we tell you plainly so you can make the right decision for your Chicago building.
Our Commercial Roof Restoration Process in Chicago
Every Chicago roof project follows the same five steps, so you understand the roof’s condition, the plan and the cost before any coating goes down.
Roof Condition Survey
We inspect the full roof surface, seams, flashings, drains and rooftop equipment, and record areas damaged by ice, ponding water and winter freeze-thaw.
Adhesion Testing
Before coating, we run adhesion tests and moisture scans to confirm the coating will bond and that the insulation underneath is dry.
Scope & Specification
We choose the coating system and thickness that suit your roof type, its drainage and Chicago's snow and temperature extremes.
Prep & Installation
Crews clean, repair and coat the roof during dry, mild weather so every layer cures properly.
Closeout & Warranty
At the end of the project you receive photos, product data and warranty documents covering the restored roof system.

Chicago Commercial Roof Coating FAQs
How does the cost of a roof coating compare to a roof replacement?
A coating restoration usually costs much less than a full tear-off and replacement, because the existing roof stays in place and there is no disposal of old material. The exact savings depend on the roof’s condition and size. Restoration also avoids the disruption of opening the roof over occupied space during a Chicago winter or spring.
How long does a silicone roof coating last?
A properly installed silicone coating typically lasts 10 to 20 years, depending on its thickness and the warranty selected. At the end of that period, the roof can often be cleaned and recoated instead of replaced. Keeping drains clear and fixing damage from snow removal quickly helps the coating reach its full life.
Which commercial roofs are good candidates for coating?
Most low-slope roofs can be coated, including TPO, PVC, EPDM, modified bitumen, built-up roofs, metal roofs and spray foam. The key is that the roof must be mostly dry and structurally sound. We test for wet insulation before recommending a coating so you do not seal moisture into the roof.
When should a Chicago commercial roof be coated?
Coatings need dry weather and moderate temperatures to cure, so most Chicago roof restoration is done from late spring through early fall. Planning the work after the spring thaw also lets us find and repair any damage from the past winter before the roof is sealed.
Does a reflective roof coating save energy in Chicago?
Yes, mainly in summer. A white reflective coating lowers the roof surface temperature on hot days, which can reduce cooling loads on the floors below. In winter the effect is small, because the sun is low and the roof is often covered with snow. For many Chicago buildings, the bigger benefit is the added waterproofing and longer roof life.
Do tenants need to leave during a roof coating project?
No. Roof coating work happens on top of the building, and tenants can stay in place. We manage rooftop access, protect intake vents from odors when needed, and schedule work to limit noise. Compared with a tear-off, coating creates far less disruption for the people inside.
