We specialize in TPO (Thermoplastic Polyolefin) single-ply roofing systems, modified bitumen (mod-bit) roofing, and EPDM rubber roofing. We also handle flat roof repairs and replacements for all commercial building types including warehouses, office buildings, retail spaces, and industrial facilities.
Project duration depends on the size and complexity of your roof. A typical commercial roof installation can take anywhere from 1-3 weeks. We work efficiently to minimize disruption to your business operations and can often work around your schedule.
With proper installation and maintenance, TPO roofs can last 20-30 years, modified bitumen systems 15-20 years, and EPDM roofs 20-25 years. The actual lifespan depends on factors like climate, maintenance, and quality of installation - which is why choosing GAF Certified contractors like Rollcog is important.
