AMES Maximum Stretch Roof Coating is a white, low-VOC elastomeric roof coating sold in a 5-gallon pail. Its 650% elongation lets it bridge small cracks and seams as the roof moves, and its 88% light reflectivity helps keep the surface cooler than dark coatings. It suits flat and low-slope roofs on homes, garages and outbuildings that need a recoat rather than a tear-off. Against standard asphalt and aluminum coatings it stretches further and reflects more, but it is a coating, not a repair: soft spots and ponding water still need fixing first.

Owners of flat and low-slope roofs generally report the coating goes on thick, stretches over small cracks and leaves a bright reflective surface. Complaints center on surface prep and on expecting it to seal larger problems it cannot.
