Our Commercial Roofing Services
Commercial Flat Roof Installation
Commercial flat roof installation involves selecting the right membrane system—such as TPO, PVC, EPDM, Modified Bitumen, or BUR—based on the building’s structure and performance needs. We assess insulation, drainage, and roof slope to ensure long-term weather protection and efficient water runoff. All installations are completed to manufacturer specifications to maintain full warranty coverage. The result is a durable, low-maintenance roofing system designed to withstand commercial use and climate conditions.
Commercial Flat Roof Repair
Flat roof repair focuses on addressing leaks, seam separations, punctures, and drainage issues to restore the roof’s watertight integrity. Our technicians use moisture scanning and diagnostic methods to locate problems accurately before making repairs. We use compatible repair materials to ensure the system remains within warranty requirements. This service extends the life of the roof and helps avoid costly structural damage.
Commercial Flat Roof Replacement
When a flat roof has reached the end of its service life, we remove the failing system and replace it with a modern, energy-efficient membrane. The replacement process includes inspecting the underlying deck, improving insulation, and installing a high-performance roofing system suited to the building’s needs. We ensure the new installation meets building codes and manufacturer warranty standards. This provides a secure, long-lasting roof designed for decades of reliable protection.
Commercial Roof Maintenance Programs
Our maintenance programs are designed to extend the lifespan of commercial flat roofs and prevent unexpected failures. They include scheduled inspections, debris removal, drainage clearing, and targeted repairs. Early detection of wear, moisture intrusion, or membrane damage helps avoid costly emergency replacements. Ongoing maintenance keeps the roof performing efficiently and protects your long-term investment.
What materials do we use on our commercial roof installations?
TPO (Thermoplastic Polyolefin)
TPO is a single-ply membrane known for its energy-saving reflective surface and strong UV resistance. It is heat-welded at the seams, creating a durable, watertight bond. This material is commonly used on commercial flat roofs to help lower cooling costs and improve long-term performance.
PVC (Polyvinyl Chloride)
PVC is a single-ply roofing membrane valued for its resistance to chemicals, grease, and fire. It maintains flexibility over time, allowing it to perform well in changing temperatures. Its heat-welded seams provide strong waterproof protection ideal for commercial and industrial environments.
EPDM (Ethylene Propylene Diene Monomer)
EPDM is a rubber-based roofing material known for its longevity and weather durability. It handles expansion and contraction effectively, making it suitable for climates with temperature swings. EPDM is also cost-effective and easy to maintain or repair.
Modified Bitumen Roofing
Modified Bitumen is a layered, asphalt-based roofing system reinforced with polymers for added flexibility and strength. It can be installed using heat welding, cold adhesives, or self-adhering sheets. This system provides strong puncture resistance and consistent long-term performance.
Built-Up Roofing (BUR)
BUR is a multi-layer roofing system constructed with alternating layers of bitumen and reinforcing fabrics. The multiple layers provide excellent waterproofing and durability. It is commonly finished with gravel or reflective coatings to improve weather and UV protection.
