Commercial Roofing Services in Chicagoland & Southern Wisconsin

TPO (Thermoplastic Polyolefin) is the most widely specified single-ply commercial roofing membrane for good reason: it performs well in both heat and cold, reflects UV radiation to reduce cooling loads, and when installed correctly — with heat-welded seams — delivers watertight performance for decades.

EPDM (Ethylene Propylene Diene Monomer) is a synthetic rubber membrane with a long track record on commercial and industrial roofs. It’s particularly well-suited to large roof areas, extreme temperature swings, and buildings where long-term low-maintenance performance is the priority.

PVC (Polyvinyl Chloride) membrane roofing offers excellent chemical resistance and is a strong choice for commercial kitchens, food processing facilities, and properties with rooftop equipment that exhausts grease or chemicals. Like TPO, PVC seams are heat-welded, producing a monolithic waterproof surface across the full roof plane.

Modified bitumen is a multi-ply asphalt-based system that delivers the redundancy of built-up roofing in a more efficient installation format. It performs well on roofs with heavy foot traffic or mechanical equipment exposure, and is commonly used for re-roofing over existing substrates where a full tear-off isn’t warranted.

Built-up roofing — alternating layers of bitumen and reinforcing fabric — is one of the most proven commercial roofing systems available. BUR excels in durability, redundancy, and fire resistance, and remains the specification of choice for certain property types and building codes. Lakeland’s commercial team has decades of experience with BUR installations on both new construction and replacement projects.

Not all commercial buildings have flat roofs. Churches, schools, retail centers with pitched sections, and low-rise office buildings often specify shingle roofing for their sloped areas. Lakeland installs commercial-grade shingle roofing with the same CertainTeed Complete Roofing System and manufacturer warranty that backs our residential shingle work.

For commercial flat roofs that are structurally sound but showing age, a coating system can extend service life significantly at a fraction of replacement cost. Roof coatings are also used to improve energy performance on existing roofs by adding reflective surface treatments. Lakeland evaluates coating eligibility during the assessment phase — we’ll tell you honestly whether your roof is a candidate.
