Commercial Roof Inspections

A documented condition assessment is the first step for every project we take on - no proposal, no replacement pitch, no conversation about scope until we have walked the roof and recorded what is actually there.

Most commercial roof failures across the Atlanta metro are predictable. They are not random events - they are the end result of deferred inspection, missed maintenance, and capital decisions made without current condition data. The Perimeter Center, Sandy Springs, and Cobb Galleria office reroof cycles running hard right now are a direct consequence of 1990s and 2000s systems that missed annual inspections, let manufacturer warranties lapse, and hit end-of-life without a capital plan. The replacement cost at that point is always higher than it would have been with a documented three-year assessment cycle.

Our inspection process starts with a physical roof walk - not a drone pass, not a thermal scan substitute for a boots-on-membrane review. We walk every drainage path, probe every flashing termination, squeeze-test seams on single-ply systems, document every penetration, and pull moisture cores at locations where surface condition or drain surcharge patterns suggest insulation saturation. The deliverable is a written report with roof zone diagrams, condition photographs keyed to zone, a prioritized repair list, and a written capital planning opinion on whether the system's remaining life supports recover, maintenance extension, or replacement planning.

Atlanta's climate forces specific inspection disciplines that matter in this market more than in others. The city averages 53 inches of rain annually - nearly all delivered in high-intensity afternoon thunderstorms from April through September, not in sustained light rain. That pattern means ponding and drain capacity are critical inspection targets: a roof that drains adequately under light rain may fail under a 2-inch-per-hour thunderstorm if drain bowls are partially clogged or drain sizing was undersized for the actual roof area. We assess drainage against intensity-duration-frequency data for the specific building's location, not just against whether water is sitting at the time of the walk.

Membrane condition: We document surface weathering, granule loss on modified bitumen, chalking on aging TPO or EPDM, alligatoring on aged BUR, blister and bubble patterns that indicate moisture migration under the membrane, seam stress and lap joint condition on single-ply, and coating delamination on previously restored roofs. Surface photographs are keyed to a zone diagram so the condition of each roof area is traceable to the photo record - not described generically in a narrative that could apply to any building.

Flashing and parapet condition: Flashing failures account for the majority of commercial roof leaks in Atlanta. We inspect base flashing at every parapet transition, counter-flashing at wall terminations, step flashing at any vertical wall intersection, and cap flashing at parapet copings. Atlanta's Piedmont granite substrate produces differential foundation movement over time that telegraphs into parapet cracking and flashing stress - we specifically document parapet crack patterns and flashing separation that indicate movement-related failure.

Drainage: Every drain bowl is inspected for debris accumulation, clamping ring integrity, strainer condition, and evidence of surcharge (ponding rings around the drain bowl indicate the drain is operating below capacity during storm events). Scuppers get the same inspection. We flag undersized drain configurations against the building's roof area and Atlanta's 100-year storm intensity data from the Gwinnett County Stormwater Management design standards, which represent the metro area's published IDF curves.
