Flat roofs on commercial buildings deal with challenges residential roofs don't: rooftop HVAC units, exhaust fans, plumbing penetrations, satellite equipment, foot traffic, and ponding water. Annawan Roofing & Maintenance has the training and equipment to handle all of it across Annawan.
Our Commercial Roofing Process
Free Assessment
Before we recommend anything, we inspect everything. Membrane, seams, flashings, drains, penetrations, parapet walls, and rooftop equipment curbs. Core samples test for trapped moisture in the insulation. Honest assessment. No scare tactics.
Project Proposal
We present options when they exist: repair vs. replace, TPO vs. PVC, 15-year vs. 20-year warranty. Each option is priced so you can make an informed decision based on your budget and building plans.
Commercial Installation
Installation phased to minimize disruption to your tenants and business operations. Debris containment, noise management, and clean work areas maintained throughout the project. Project manager on-site for every commercial installation.
Warranty & Maintenance
Manufacturer warranty registered upon completion, 15-20 year coverage depending on system and build-up. We offer maintenance contracts to keep your warranty valid and your roof performing for its full life span.

About Our Annawan Commercial Roofing Services
Commercial roof coatings can extend the life of an existing roof by 10-15 years for a fraction of replacement cost. Silicone and acrylic coatings over existing TPO, EPDM, or metal substrates. Not every roof qualifies. We core sample and moisture scan before recommending a coating.
We offer annual and semi-annual maintenance contracts for Annawan building owners. Regular inspection catches small problems before they become expensive emergencies. Seam checks, flashing inspection, drain clearing, and minor repairs, all documented with photos in a maintenance report.
