Expert Verdict — Reviewed by the SuperArbor Pro Desk
Ponding water is one of the fastest ways to age a flat roof, so filling low spots and building crickets is preventive maintenance worth doing before membranes fail. PondPatch's low cured weight is an advantage over poured fills on older decks. Taper feathered edges smoothly into surrounding membrane so new water paths drain, and prime or confirm membrane compatibility per the roofing system manufacturer before embedding the fill.
Work safely on low-slope roofs, wear gloves and eye protection when mixing and troweling cementitious material, and follow the pail's handling directions.
