Flat roofs on commercial buildings deal with challenges residential roofs don't: rooftop HVAC units, exhaust fans, plumbing penetrations, satellite equipment, foot traffic, and ponding water. New Underwood Roofing & Maintenance has the training and equipment to handle all of it across New Underwood.
TPO is our most-installed commercial membrane in New Underwood. White reflective surface for energy efficiency, hot-air welded seams that are stronger than the membrane itself, and 15-20 year manufacturer warranties. We install 60-mil and 80-mil systems, fully adhered or mechanically attached, over polyiso insulation.
