When it comes to protecting your investment, few choices are as crucial as selecting the right commercial roofing system. Whether you're renovating an older facility or constructing a new one, understanding what is the best commercial roofing material for long-term durability is a smart move. At Riverside Roofing, we guide building owners, property managers, and contractors through this decision with expert care, ensuring every roof delivers strength, performance, and value.
With decades of hands-on experience, Riverside Roofing has worked with every central commercial roofing system under the sun. Let’s explore the best options on the market and help you determine the right fit for your commercial building.
What Is the Best Commercial Roofing Material for Flat Roofs?
The answer depends on your building’s specific needs, but when it comes to flat roofs, EPDM roofing, TPO roofing membranes, and PVC (polyvinyl chloride) systems are top contenders. These single-ply roofing options offer excellent waterproofing, UV resistance, and flexibility. At Riverside Roofing, we often recommend EPDM rubber roofing for budget-conscious clients seeking long-term performance.
Why EPDM Roofing Stands Out in Commercial Projects
EPDM, or ethylene propylene diene monomer, is a synthetic rubber membrane widely used in commercial roofing systems. Its durability, ease of installation, and resistance to weathering make it a favorite among contractors. Riverside Roofing has installed countless EPDM systems, especially for low-slope or flat commercial roofs, offering clients a balance of affordability and resilience.
Benefits of TPO Roofing Membranes
TPO (thermoplastic polyolefin) is a heat-reflective and energy-efficient option that performs exceptionally well in hot climates. These white roofing membranes reflect sunlight, reducing HVAC costs—an ideal feature for warehouses or retail commercial buildings. Riverside Roofing uses TPO for clients seeking green roofing solutions that also deliver low maintenance.
Is PVC (Polyvinyl Chloride) the Right Material for Your Roof?
PVC roofing is another single-ply roofing system praised for its chemical resistance and strength. It’s particularly suitable for restaurants or industrial buildings where grease and chemical exposure are a concern. At Riverside Roofing, we help customers understand whether PVC is right for their application, especially when energy efficiency and durability are top priorities.
The Power of Metal Roofing in Commercial Applications
Metal roofs remain one of the strongest choices for both sloped and steep commercial structures. From corrugated steel panels to standing seam systems, durable metal roofing is long-lasting and low-maintenance. Riverside Roofing installs high-performance metal roofing systems that withstand harsh weather, making them perfect for the Pacific Northwest and beyond.
Modified Bitumen: A Time-Tested Material for Flat Roofs
Modified bitumen is an asphalt-based material ideal for flat or low-slope roofing systems. Reinforced with fiberglass or polyester, it resists tearing and can be applied using various methods, including heat or adhesive. Riverside Roofing recommends modified bitumen for buildings requiring a time-tested, multilayer solution that resists heavy foot traffic and extreme temperatures.
Understanding Roof Coatings for Enhanced Longevity
Roof coatings can extend the life of your existing roof system by creating a seamless, watertight barrier. Elastomeric and silicone coatings work well on flat roofs, EPDM, PVC, and metal roofing systems. Riverside Roofing offers premium roof coatings as part of our preventative maintenance services, helping commercial clients save money while protecting their assets.
Choosing the Right Roofing Materials Based on Slope
The slope of your commercial roof plays a major role in determining the best roofing materials. Flat roofing systems benefit most from EPDM, TPO, and PVC, while steep slope roofs may favor metal or architectural shingles. Riverside Roofing evaluates your building's design and helps you choose the right system that matches your performance needs and budget.
Comparing Single-Ply Roofing Systems: EPDM vs. TPO vs. PVC
Choosing between EPDM, TPO, and PVC roofing membranes can be tricky without a clear understanding of each type. While EPDM offers affordability and strength, TPO provides energy efficiency, and PVC delivers chemical resistance. Riverside Roofing provides side-by-side evaluations so clients can make informed decisions that suit their commercial buildings and goals.
