Commercial Roofing in Arnold, Imperial, Oakville, and Fenton

Commercial roofing in St. Louis takes the brunt of widely varying temperature fluctuations. To ensure the roof maintains a tight seal against the elements, the type of roofing system used is a vital consideration. EPDM is a rubber membrane; TPO is similar but offers several benefits that EPDM does not.

Energy Efficiency

To improve energy efficiency, the reflective qualities of TPO work better than EPDM to maintain a consistent temperature in the building, no matter what your heating source.

Puncture Resistance

A puncture can often turn into a leak, and TPO offers greater puncture resistance than reinforced EPDM.

Installation Convenience

Flexibility often equals a more efficient installation. TPO can be installed in several ways, including being mechanically attached and adhered with the Rhinobond® System.

Dimensional Stability

Less movement of the material during temperature changes means TPO has better dimensional stability. EPDM is more likely to shrink, which can cause issues on your roof.

Seam Strength

No commercial roof is without seams, and being able to rely on their strength is critical. TPO seals can be welded; which creates a stronger bond than EPDM taped seams.

Ease of Repair

Because TPO is thermoplastic, the seams can be heat-sealed, and so can repairs. Your roofing contractor can just clean the material and heat-weld the repair.

Anytime you’re considering what type of materials to use for your roofing project you should take into consideration what your wants and needs are. What functions and durability do you need it to have? What makes the most sense both economically and functionally? Consulting with an experienced, reliable commercial roofer is a great first step to determine what the best course of action will be for your company.
