Our comprehensive maintenance services are designed to keep your roof in optimal condition.

This approach reinforces the roof’s integrity, improves energy efficiency, and reduces long-term maintenance costs, providing lasting protection with minimal disruption to operations. It’s a strategic investment that extends roof performance while significantly reducing capital expenditures associated with full roof replacements.
Flat & Metal Roof Overlay is a practical and cost-efficient way to extend the lifespan of your existing roof without the expense of a full replacement. This method involves adding a new roofing layer over the current system, enhancing its durability and performance. For metal roofs, we offer retrofit systems that improve structural integrity and provide added protection, while maintaining the original design. Overlays use high-quality materials like TPO or EPDM to ensure long-term reliability and resistance to the elements, all backed by long-term warranties. This service minimizes disruption, reduces waste, and provides an economical alternative to complete roof replacement.

Commercial Flat Roof Company also provides exceptional metal roofing services
Metal roofing performs exceptionally well across St. Louis’s diverse commercial and industrial landscape—from warehouses to modern retail centers. We specialize in restoring, repairing, and maintaining metal roofs, helping property owners extend the life of their roofing systems. By applying protective roof coatings, we enhance durability and improve energy efficiency by reflecting heat. Our metal roofing solutions are tailored to meet the demands of facilities throughout the St. Louis metro area, including cities like Chesterfield, Fenton, and Hazelwood—delivering long-term performance while maintaining a professional appearance.
Flat Roof Types
Our expertise also means we select the best materials.

For properties prioritizing energy efficiency, TPO membranes reflect sunlight, reducing cooling costs by up to 30%—a boon for warehouses in Earth City or manufacturing plants in Affton.

For heavy-traffic rooftops, modified bitumen offers layered durability and is reinforced with fiberglass to withstand foot traffic and equipment weight.

We install EPDM rubber roofing, a stalwart against temperature swings, known for its flexibility and leak-resistant seams—ideal for St. Louis flat roof repair where minor leaks can escalate into structural issues.

Roof coatings are protective layers applied to existing roofing systems to enhance durability, waterproofing, and energy efficiency. Applying a roof coating can extend the life of a roof, improve energy efficiency by reflecting sunlight, and provide a cost-effective alternative to full roof replacement.

Polyvinyl Chloride (PVC) roofing is a single-ply membrane known for its durability, chemical resistance, and energy efficiency. It's particularly suited for flat or low-slope commercial roofs. PVC roofing is also recyclable, making it an environmentally friendly option for commercial buildings.

Commercial and industrial roofs in St. Louis are not all the same.
Compliance
Our team's hyperlocal knowledge ensures compliance with regional building codes, like St. Louis County's wind uplift requirements or Illinois's energy efficiency standards for commercial flat roofing. We've reinforced roofs in the Mississippi River floodplain, where waterproofing is non-negotiable, and retrofitted aging structures in Marine Villa with slope-added systems to combat water pooling.
Maintenance
We also offer maintenance programs are tailored to your needs. Spring inspections focus on winter damage such as cracked flashings or loose fasteners. Fall preparations include clearing debris from drains before leaf drop clogs systems. We install walkway pads to protect membranes from abrasion for facilities with rooftop equipment, too.
Sustainability
St. Louis businesses are increasingly prioritizing sustainability, and roofing plays a pivotal role. Cool roofing systems, like white TPO, reduce urban heat island effects in dense areas. For retrofits, we layer new membranes over existing roofs, diverting tons of waste from landfills—a practice embraced by Webster University during recent renovations.
Benefits
Metal roofs amplify these benefits. Made from 95% recycled materials and fully recyclable at end-of-life, they align with the eco-initiatives of companies in the Cortex District. Pair them with solar-ready designs, and businesses in Sunset Hills can offset energy costs while contributing to Missouri's renewable energy goals.
