The building you operate your business from represents a huge investment in your livelihood that needs the greatest protection you can give it. When considering a contractor for your commercial roofing needs, the decision should not be taken lightly. You should hire someone certified in the product that is being installed to ensure its integrity. EPDM (ethylene propylene diene monomer) and TPO (thermoplastic polyolefin) are the gold standard for commercial flat roofing systems.
