Commercial Roofing Services We Offer in Lithonia
✓TPO Membrane Replacement
Heat-welded TPO systems installed over new insulation on commercial flat roofs to resist UV and ponding water common in Marietta summers.
✓Modified Bitumen Repair
Torch-down or cold-applied modified bitumen patches and full replacements that restore waterproofing around HVAC units and parapets.
✓Commercial Roof Coating
Elastomeric coatings applied to extend the life of existing metal and membrane roofs while reflecting heat in Cobb County’s hot summers.
✓Drainage and Scupper Installation
New primary and secondary drains plus scuppers added to correct standing water issues on older commercial buildings near Glover Park.
✓Metal Panel Roofing
Standing seam and screw-down metal systems for sloped commercial structures in Forest Hills and Whitlock Heights that need wind resistance.
Marietta commercial buildings in areas like Downtown Marietta and near Marietta Square often feature older flat roofs that collect standing water during the humid subtropical summers. High humidity accelerates membrane blistering and seam failure on TPO and EPDM systems, while mild winters still allow freeze-thaw cycles around roof drains and penetrations. Cobb County code requires positive drainage and specific wind-uplift ratings that change with building height and exposure near Kennesaw Mountain.
Roof replacement on commercial properties in Whitlock Heights or Forest Hills typically involves removing multiple layers of existing modified bitumen before installing new insulation and cover boards. Edge details around HVAC curbs and parapets must account for the heavy tree cover common in these neighborhoods, which drops debris that clogs scuppers and leads to interior leaks. Proper attachment methods differ between steel deck and concrete deck buildings found throughout the county.
