The Roofing Challenge: Saturated Deck, Active Leaks & Severe Ponding Water

The 28,000 sq ft commercial plaza housed 8 retail tenants whose businesses were threatened by chronic roof leaks during summer deluge rainstorms.

Core testing revealed that the existing multi-ply asphalt built-up roof had suffered widespread moisture saturation across 40% of its fiberglass insulation core. Severe structural deck deflections had created permanent ponding water reservoirs up to 3 inches deep around rooftop package AC units.

Because the plaza housed operating restaurants, boutique fitness centers, and medical retail, the reroof could not cause interior ceiling leaks, odorous asphalt fumes, or customer parking lot closures. Planet Construction engineered a phased, low-odor, single-ply solution.

The Engineering Execution: Phased Commercial Single-Ply Assembly

Directly managed under Master Roofing License CCC1329271, our commercial crews completed daily tear-offs and tie-ins to maintain 100% watertight security every evening.

01

Complete Tear-Off & Structural Deck Pull-Testing

Old gravel, asphalt plies, and waterlogged insulation were removed to the bare structural deck. TAS 105 fastener pull-tests verified 450+ lbs uplift resistance per anchor.

02

Self-Adhering Vapor Retarder & Air Barrier

Application of high-performance self-adhered vapor barrier over the primed concrete deck, preventing internal humidity migration into the insulation matrix.

ASTM D1970 Vapor Barrier • Perm < 0.1
03

Tapered Polyiso Insulation Slope-to-Drain System

Engineered multi-layer staggered polyisocyanurate insulation boards providing an R-30 thermal barrier and a precision 1/4-inch per foot slope to scuppers and internal drains.
