Commercial roof installation for Atlanta buildings

TPO and PVC are white thermoplastic membranes with seams welded by hot air, and on most Atlanta commercial roofs one of them is the default. TPO costs less and suits offices, retail and warehouses. PVC holds up better where grease or chemicals land on the roof, so it is the usual choice over restaurant kitchens and some light industrial space. Both reflect sunlight and lower cooling load, and both depend on careful welding, so we probe seams daily as the roof goes down.

EPDM is a rubber membrane laid in wide sheets and joined with seam tape, with decades of use on low-slope commercial roofs. It is flexible, forgiving on older buildings that move, and often economical on roofs that see little foot traffic. The standard black sheet absorbs heat, so inside city limits a full replacement needs a white EPDM or another system to meet the reflectance rule. EPDM punctures more easily than welded membranes, so walkway pads go down along every service route.

Metal suits commercial buildings with enough slope to shed water: churches, schools, shops and pre-engineered steel buildings. Standing seam panels hide their fasteners and move with temperature, while exposed-fastener panels cost less and suit utility buildings. We check the structure and purlin spacing, match the panel to the building's wind requirements, and detail the trim at walls, ridges and gutters, which is where metal roofs leak if they are going to. Light-colored finishes also help with cooling cost on a big, sunny roof.
