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.
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.
A puncture can often turn into a leak, and TPO offers greater puncture resistance than reinforced EPDM.
Flexibility often equals a more efficient installation. TPO can be installed in several ways, including being mechanically attached and adhered with the Rhinobond® System.
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.
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.
