Who is commercial roofing for?

Property managers, business owners, facility directors, and multi-family asset managers. The buildings are typically flat or low-slope and the work has to coordinate around tenants, business hours, deliveries, and access requirements that residential projects don't share.

We work on office buildings, retail centers, restaurants, multi-family residential (3+ stories), warehouses, and light industrial facilities across the St. Louis metro and Metro East. Project size ranges from a single roof-section repair on a strip-mall storefront to full-system replacement on a 50,000 sq ft warehouse.

Commercial work is different from residential in three ways: scheduling has to coordinate around the building's actual operations, the systems are different (single-ply membranes, not shingles), and the warranty structure includes both manufacturer and contractor obligations that have to be properly documented for insurance and tax purposes.

What commercial roofing systems do you install?

TPO (thermoplastic polyolefin), EPDM (rubber), PVC single-ply, modified bitumen, standing-seam and corrugated metal, and silicone or acrylic restoration coatings for roofs that aren't quite ready for full replacement. System choice depends on roof size, slope, exposure, and budget.

How do you coordinate around tenants and business hours?

We schedule around your operations. Most flat-roof work is non-disruptive to the inside of the building, but loading, deliveries, and tenant access often require off-hours or weekend scheduling. We map dumpster placement, equipment staging, and crew access to minimize tenant impact — and confirm logistics in writing before the start date.

  • Pre-project walk-through to identify tenant impact zones, parking implications, and access requirements.
  • Equipment staging and dumpster placement coordinated with property management.
  • Off-hours and weekend work scheduled when the project requires it.
  • Tenant notifications drafted with property management before the project starts.
  • Daily progress reports during multi-day projects so building management is never out of the loop.

What does commercial roofing cost?

Commercial roofing pricing is highly project-specific. Single-ply replacements typically run $7–$14 per square foot installed; modified bitumen runs $8–$13; restoration coatings on existing roofs run $3–$6 per square foot. Project size, access, and existing-system tear-off determine the final number.

We provide free, line-itemized estimates for every commercial project, including a detailed scope of work, material specifications, manufacturer warranty terms, our workmanship warranty, project timeline, and access logistics. Larger projects may include phased pricing, milestone payment schedules, and coordination with your insurance carrier or financing partner.

For commercial property managers and asset owners, we provide consolidated documentation in formats that work with insurance claims, capital expenditure approvals, and 1099 contractor reporting. If you have a specific format requirement, tell us at the estimate — we'll match.

Do you handle commercial emergency response?

Yes. We respond to active commercial leaks and storm damage during business hours, typically same-day for property-management clients with active service relationships. We tarp-and-secure to stop water intrusion, document the damage with photos, and schedule the actual repair with proper system materials.

Commercial leaks frequently start small and escalate fast — water gets into ceiling tiles, electrical, and tenant inventory. We treat commercial emergency calls with the same urgency as residential: fast triage, immediate stabilization, full documentation for the insurance file.

If you're a property manager with multiple buildings, we can establish a service relationship that prioritizes your portfolio for emergency response. Call us to discuss specifics.
