TPO flat roofing and full commercial replacement for businesses, property managers, and institutions across the St. Louis metro.

Commercial Roofing Experience

Commercial Roofing Built to Handle St. Louis Weather

We’ve completed commercial roofing projects across the St. Louis metro, including school district buildings and institutional facilities. TPO (thermoplastic polyolefin) membrane roofing is the current standard for flat and low-slope commercial roofs — it’s energy efficient, handles St. Louis heat and cold better than older BUR or EPDM systems, and requires far less maintenance over its service life. We use commercial-grade TPO systems with full weld seams and proper drain placement for the Missouri climate.

Commercial roofing requires a different level of planning and coordination than residential. Businesses can’t just shut down for a week. Property managers need a project schedule they can hand to tenants. School facilities have to work around the academic calendar. We plan your commercial project around your operating schedule, stage material deliveries to minimize disruption, and keep you informed throughout the job — not just at the beginning and end.

How It Works

The Commercial Roofing Process

01

Commercial Assessment

We inspect your full roof surface, drainage system, existing membrane or built-up layers, and deck condition. You get a clear assessment of what’s failing, what’s salvageable, and what the replacement scope looks like — before any commitments are made.

02

Proposal & Planning

We deliver a written proposal with a detailed project timeline that accounts for your operating schedule. If you have specific blackout dates, tenant notifications to send, or facility management requirements to meet, we build those into the plan from the start.

03

Material & Crew Coordination

We order commercial-grade TPO materials, stage deliveries to minimize site disruption, and assign our licensed commercial crew. Our project lead stays on-site and in contact with your facility contact throughout the installation.

04

Installation & Final Walkthrough

After installation, we conduct a post-project inspection, review the completed work with you or your facility manager, and provide all warranty documentation. We don’t consider the job closed until you’ve signed off on it.

Common Questions

Commercial Roofing FAQ

How does TPO compare to other commercial roofing systems?
TPO has become the preferred system for most flat and low-slope commercial buildings for several reasons. It reflects UV radiation better than EPDM (rubber roofing), which reduces cooling costs in summer. It’s heat-welded at the seams, which creates a stronger, more watertight bond than adhesive seams. It’s also lighter than built-up roofing (BUR/tar-and-gravel), which reduces structural load. For most commercial applications in St. Louis, TPO gives you the best combination of energy efficiency, durability, and total cost over the life of the roof.
What does commercial roofing cost per square foot in St. Louis?
Commercial roofing replacement in the St. Louis market typically runs $6 to $12 per square foot for TPO, depending on roof complexity, access conditions, existing deck condition, and whether a full tear-off is required. Larger square footage generally brings the per-foot cost down. We provide written, line-item estimates for every commercial project so you know exactly what’s driving the price before you commit to anything.
How long does a commercial roof replacement take?
Timeline depends on roof size and complexity. A single-story commercial building with a straightforward flat roof might be completed in three to five days. Larger buildings, multi-section roofs, or projects requiring significant deck repair take longer. We build your timeline into the written proposal before the project starts, so you can plan accordingly and communicate with tenants or staff in advance.
Do you handle commercial insurance claims for storm damage?
Yes. Commercial storm damage claims follow a similar process to residential — we inspect and document the damage, adding FAA-licensed drone documentation for steep or hard-to-access roofs, before your adjuster arrives, communicate directly with your insurance representative, and are present during the adjuster inspection. Commercial claims can be more complex because of business interruption considerations and higher coverage thresholds, but we’ve worked through the process with commercial clients across St. Louis and know what documentation insurance companies require.
What size commercial jobs do you handle?
We work on commercial projects ranging from small retail and office buildings to larger institutional facilities including school district buildings. If you manage a multi-building property or a large facility requiring phased work, we can build a phased project plan. Contact us to discuss your specific building — we’ll give you an honest assessment of whether the scope is a fit for our crew and timeline.
