Roof Capital Planning

Capital planning for commercial roofs in Atlanta should be driven by actual condition data - moisture maps, zone condition ratings, remaining service life estimates - not by age alone or square-footage formulas. We produce the data and the forecast.

A commercial roof replacement on a 100,000 square foot Atlanta office building costs between $600,000 and $1,200,000 depending on system specification, deck condition, and access complexity. That is a capital event that should appear in a 5-year capital plan 3 to 4 years before the work needs to happen, not as an emergency line item when the roof fails. Capital planning for commercial roofs means producing condition-based remaining service life estimates, running recover versus replace analysis where the decision is not obvious, and putting a year-by-year capital forecast in front of the building owner or asset manager with enough lead time to plan the financing.

Atlanta's commercial building inventory makes this planning work particularly important right now. The metro's 1990s and 2000s office and industrial construction wave - concentrated in the Perimeter Center, Sandy Springs, Buckhead fringe, Cobb Galleria, and Gwinnett corridors - put a large volume of commercial buildings on roof systems that are now at or past their original warranty life. Owners and managers of these buildings who have not done a documented condition assessment recently are making capital allocation decisions without the information that determines whether they need $300,000 of recover work or $900,000 of full replacement.

Our capital planning process starts with inspection and moisture assessment. The condition data drives the remaining service life estimate, which drives the capital forecast. We present recover versus replace analysis where the membrane and insulation condition make the decision non-obvious. And we produce the capital forecast in a format that works in a property financial model or institutional capital reserve schedule.

The recover decision depends on three things: insulation moisture content, deck condition, and the existing membrane's remaining service life. If insulation is dry (moisture cores read below 10 percent by weight), the deck is sound, and the existing membrane has documented remaining service life, a recover system adds 15 to 20 years at roughly 45 to 55 percent of the cost of full replacement. In Atlanta's market, with current TPO and coatings pricing, that recover versus replace cost gap is meaningful enough to justify the condition assessment work required to make the decision defensibly.

If insulation moisture cores show 25 percent or more of sampled locations reading wet, recovery is not the right scope regardless of membrane surface condition. Recovering wet insulation voids the new system's warranty, traps the moisture, and typically produces re-leakage within 5 years. The honest scope is replacement with full insulation removal. We pull enough cores to make this determination statistically defensible - not two cores on a 50,000 square foot roof, which tells you nothing about the moisture distribution.

Deck condition is the variable that most often changes the capital estimate unexpectedly. In Atlanta's older commercial building stock - particularly the 1960s through 1980s warehouse and industrial inventory in the Marietta corridor, South DeKalb, and the Forest Park industrial district - metal deck corrosion and plywood deck rot are common. We pull deck inspection ports at moisture-core locations to check the substrate before finalizing the capital estimate.
