COMMERCIAL ROOFING SERVICES IN ST. LOUIS

TPO Roofing

Thermoplastic polyolefin (TPO) is one of the most popular commercial flat roofing systems in the St. Louis market — valued for its energy efficiency, durability, and cost-effectiveness. We install TPO roofing systems for commercial properties of all sizes throughout St. Louis and St. Charles County.

EPDM Flat Roofing

Ethylene propylene diene monomer (EPDM) is a durable rubber roofing membrane widely used on commercial and industrial buildings. Known for its longevity and resistance to UV exposure and weathering, EPDM is a reliable solution for St. Louis commercial flat roof applications.

Modified Bitumen Roofing

Modified bitumen systems provide excellent waterproofing and durability for low-slope commercial roofs. Multi-layer systems offer superior protection against Missouri’s freeze-thaw cycles and storm activity. We install and repair modified bitumen systems for commercial properties throughout the St. Louis metro.

Metal Roofing

Standing seam and exposed fastener metal roofing systems provide exceptional longevity and low maintenance for commercial and industrial buildings. Metal roofing is increasingly popular for St. Louis commercial properties due to its durability, energy efficiency, and minimal lifecycle cost.

Commercial Roof Repair

Leaks, membrane failures, flashing issues, and ponding water are common commercial roofing problems in the St. Louis area. We diagnose and repair commercial roof issues quickly to minimize business disruption. Most commercial repairs can be completed without interrupting daily operations.

Commercial Roof Replacement

When repair is no longer cost-effective, Cardinal Contractors manages full commercial roof replacement projects for St. Louis businesses. We coordinate materials, permits, scheduling, and installation to minimize downtime and disruption to your operations.

OUR COMMERCIAL ROOFING PROCESS

Cardinal Contractors follows a structured commercial roofing process designed to minimize business disruption, meet code requirements, and deliver lasting results.

Step 1 — Free Commercial Inspection & Assessment

We begin with a thorough inspection of your commercial roofing system — membrane condition, flashing, drains, penetrations, and structural components. We provide a written assessment and photographic documentation of all findings before recommending a course of action.

Step 2 — Proposal & Material Selection

We provide a detailed written proposal outlining the scope of work, materials, timeline, and cost. For roof replacements, we help you select the right system for your building type, budget, and long-term maintenance goals. We pull all required commercial permits for applicable St. Louis and St. Charles County municipalities.

Step 3 — Scheduled Installation

Commercial roofing projects are scheduled to minimize disruption to your business operations. Our crews work efficiently and maintain a clean job site throughout the project. For occupied buildings, we coordinate work schedules around your business hours where possible.

Step 4 — Final Inspection & Warranty

We complete a final inspection with the property owner or manager before considering any commercial project complete. All commercial work is backed by our workmanship warranty. Most commercial roofing systems also carry manufacturer warranties on materials.

COMMERCIAL STORM DAMAGE IN ST. LOUIS

St. Louis commercial properties sustain significant roofing damage from hail, wind, and severe storms every year. Flat and low-slope commercial roofs are particularly vulnerable to storm damage — and the resulting leaks can cause costly interior damage to inventory, equipment, and building systems.

Cardinal Contractors responds quickly to commercial storm damage throughout the St. Louis metro. We provide free commercial storm damage inspections, complete photographic documentation for insurance purposes, and can assist with commercial insurance claims. Our team meets with commercial insurance adjusters onsite to ensure all storm damage is properly identified and included in the claim scope.
