Commercial Roof Replacement

Full-system tear-off and replacement on Atlanta commercial flat and low-slope roofs - scoped against your capital horizon and closed out with manufacturer warranty documentation that holds up over the next two decades.

Most commercial roof replacements in the Atlanta metro get scoped reactively. The roof leaks, someone calls three contractors, and the lowest bid wins. That replacement runs the same membrane on the same insulation against the same flashing details - and then leaks again within two years. We do not work that way.

Atlanta's climate makes this problem worse than most markets. High relative humidity from June through September drives condensation into unprotected insulation stacks. The region's frequent afternoon thunderstorms - Atlanta averages 53 inches of rain annually, well above the national average - put constant pressure on seams, flashings, and drains. And the Piedmont granite ridge under most of the metro produces slow but measurable differential movement in building foundations that telegraphs into parapet cracking and membrane stress at building joints over time.

Our replacement scope starts with a roof walk and moisture-core pull on any roof we suspect has saturated insulation. We document deck condition, parapet flashing condition, drain status, every penetration, and every prior repair. The replacement scope then specifies the membrane, the insulation stack (including R-value to current Georgia energy code), the fastener density to code wind-uplift for the building's exposure category, the manufacturer warranty path, and the maintenance contract that keeps the warranty active. The deliverable at closeout is the warranty document, the roof zone diagram with all closeout photos, the maintenance contract, and a written record the next reroof cycle can build against.

Recover-versus-replace is the first decision in any aging-roof scope. Atlanta's high-humidity climate means insulation saturation is more common here than in drier markets - moisture infiltrates the stack through minor membrane failures and never fully dries out because ambient humidity keeps the insulation from releasing it. We pull moisture cores in five to ten representative locations on roofs we suspect have saturation. If more than 25 percent of cores read wet, replacement is the honest scope. Recovering wet insulation traps the moisture, voids the new warranty, and typically produces the same leak failure within five years. If under 25 percent, a recover with targeted insulation replacement at wet areas can extend the asset another 15 to 20 years at roughly half the capital cost of full replacement.

Deck condition is the second decision. We pull deck inspection ports under wet cores and at visible deflection points. Corroded metal deck, rotted plywood or OSB decking, or delaminated lightweight concrete all change the project scope and cost significantly. Owners need to know this before the project starts, not when the crew opens the roof and stops work waiting for authorization to proceed.

Age of the existing system is the third factor. Atlanta's 1990s and 2000s suburban office reroof cycle is well underway - Perimeter Center, Sandy Springs, and the Cobb Galleria corridor are all running large inventories of roofs from that era that are past warranty and approaching end of service life. For these buildings, the recover math often does not work even if insulation is dry, because the existing membrane's remaining service life cannot justify the cost of a quality recover installation.
