Commercial Roofing in Belleville, IL & the St. Louis Metro East

iRestore STL is a licensed and insured commercial roofing contractor working with business owners, property managers, and facility teams throughout the Metro East and Greater St. Louis area. We handle everything from a single-tenant retail building to multi-roof commercial portfolios, with the same direct, no-pressure approach we use on residential projects.

Commercial Roofing Systems We Install

• TPO (Thermoplastic Polyolefin): A reflective single-ply membrane that's become the default for new low-slope commercial roofs. Energy efficient, seam-welded, and competitively priced.
• EPDM (Rubber Roofing): Durable single-ply rubber membrane that holds up well to UV exposure and temperature swings. Long track record on warehouse, office, and industrial buildings.
• Modified Bitumen: Multi-ply asphalt-based system for low-slope roofs that need extra puncture resistance — common on rooftop-equipment-heavy properties.
• Standing-Seam Metal: Long-life metal panel systems for sloped commercial buildings. Decades of service life with minimal maintenance.
• Asphalt Shingle (Steep-Slope Commercial): For churches, retail strip centers, and multi-family properties with pitched roofs, we install GAF architectural shingle systems backed by manufacturer warranties.

Commercial Roof Repair & Maintenance

Most commercial roof failures are predictable — failed seams, clogged drains, deteriorated flashing around HVAC curbs and penetrations, ponding water. We offer repair-only visits as well as scheduled maintenance programs that catch small issues before they turn into a six-figure insurance claim.

• Membrane patches and seam repairs
• Flashing repair and replacement around HVAC, vents, and skylights
• Drain and scupper cleaning and reseal
• Coatings and recoats to extend roof service life
• Annual or bi-annual inspection programs

Why Property Owners Hire iRestore STL

• Licensed and insured with commercial general liability and workers' comp.
• GAF Master Elite certified — fewer than 2% of roofing contractors hold this certification, and it lets us offer extended manufacturer warranties on commercial systems.
• Insurance claim experience. Our owner is a Licensed Public Adjuster who has helped clients secure a 98% claim approval rate on storm damage claims. For commercial properties, that's a meaningful advantage.
• Local crews, local accountability. We're based in Belleville, IL — not a chase-the-storm operation that disappears after the job.
• Honest scoping. We'll tell you when a repair is the right call instead of pushing a replacement.
