One product. Many roofs.

ACC is designed first and foremost for existing metal roofs — and works across the details, substrates and building types that go with them.

**Metal roof restoration**Extend the life of aging metal roofs without tear-off. ACC reflects heat, stops leaks and prevents further corrosion in one layer over the existing panels.

**Cool roof retrofit**Turn a hot, dark or weathered metal or concrete roof into a cool, reflective surface — reducing heat gain into the building below.

**Coastal & industrial corrosion**Salt spray, acid rain and chemical exposure eat metal roofs. ACC’s anti-corrosion face is built for coastal, industrial and agricultural sites.

**Gutters, flashings & details**Ridges, skylights, parapets, penetrations, expansion joints, box gutters and drainage outlets — the places most roofs leak first.

**Solar-ready rooftops**Restore and protect the roof before or around a PV installation, and seal detailing around array mounts and penetrations.

**Ag buildings, silos & canopies**Grain stores, barns, packing sheds, silos and exposed outdoor structures where heat and corrosion damage product and equipment.

Is ACC right for your roof? ACC is a restoration and weathering membrane for existing roofs and roof details. It is not a replacement for a full single-ply or built-up roof system. Send us photos of your roof and we’ll give you a straight answer.
