Efficient Systems That Protect Assets and Reduce Downtime

We recommend materials that match your building and budget, and we explain why. Our crews handle commercial flat roofing with careful substrate prep and proper slope to drains. We provide commercial roof inspection services that document conditions and prioritize work to prevent disruptions.

When a full upgrade is needed, our commercial roof installation follows manufacturer requirements for watertight seams and long service life. After the project, commercial roof maintenance plans help extend performance with targeted repairs and scheduled checks.

  • Inspection and Scope: We evaluate membrane condition, seams, flashings, and penetrations, then create a scope that prevents future leaks and aligns with warranty terms so planning and budgeting are simpler.
  • System Selection: We compare TPO and EPDM, explain energy and maintenance tradeoffs, and discuss metal options for select areas to balance durability, appearance, and cost of ownership.
  • Project Phasing: We phase work by sections, coordinate deliveries, and set safe access routes to keep your business moving while crews install, with daily debris removal and clear site markings.
  • Warranty and Maintenance: We review care items, schedule follow up inspections, and document repairs so records stay current and the roof performs through tough Midwest weather.

Protect Operations and Move Forward with Confidence

Your roof should support business, not interrupt it. With our team, you get accurate assessments, organized staging, and dependable timelines. We communicate clearly with owners, facility managers, and tenants so expectations stay aligned. Crews protect entrances, mark work zones, and maintain a tidy site from start to finish. When weather threatens, we secure open areas and keep you informed about next steps.

If your project involves insurance, we document conditions, meet the adjuster on site, and manage supplements when the initial estimate misses critical items. If this is a planned upgrade, we help you select a system that fits performance goals and budget targets.

After installation, we can set maintenance visits that reduce surprises and extend service life.

Frequently Asked Questions About Commercial Roofing

  • What happens during a commercial roof inspection?

    We photograph the roof, check seams, flashings, penetrations, and drainage, and assess membrane condition. You receive a summary of findings, prioritized recommendations, and options that match your budget and downtime tolerance. This documentation supports planning, maintenance decisions, and insurance discussions when storms are involved.

  • How do you minimize disruptions during installation?

    We phase the project by roof sections, coordinate staging, and set safe routes for employees and customers. Material deliveries are scheduled to avoid peak hours. We keep entrances clear where possible, maintain daily cleanup, and provide updates so operations continue while work progresses on a predictable timeline.

  • Which system is better for my building, TPO or EPDM?

    Both are proven single-ply membranes. TPO offers heat-welded seams and reflective properties, while EPDM provides flexible performance and long track records. We evaluate slope, exposure, existing conditions, and energy goals to recommend the right fit, then present costs and timelines so decisions are clear.

  • Do you offer maintenance after installation?

    Yes. We provide maintenance plans that include scheduled inspections, targeted repairs, and documentation to help sustain performance and meet warranty conditions. Regular checks catch small issues before they become leaks, protecting interiors, inventory, and equipment while extending the useful life of the roof system.

  • Can you coordinate with insurance after storm damage? Answer Five:

    We can. Our team documents damage with photos, meets the adjuster on site, and handles supplementing when the initial estimate overlooks necessary items. You select materials while we manage process steps and communication, with the goal of restoring the roof correctly and aligning scope to real repair needs.
