Thermoplastic polyolefin (TPO) is a single-ply roofing membrane commonly used on low-slope commercial roofs. TPO roof systems most commonly come in white and are mechanically fastened, self-adhered, or fully-adhered and welded at the seams.

Singly-ply TPO membranes can often be difficult for coatings to adhere to. When applied to a suitably cleaned, weathered TPO roof, Metacrylics TPO Primer and Metacrylics coatings provide optimal adhesion. TPO roofs that have leaking or deterioration issues due to ponding conditions and seam failures should be coated with Metacrylics. Metacrylics coatings withstand ponding conditions and resist debris, protecting the existing membrane from water infiltration.

Built-Up Roofing (BUR) is typically multiple plies of roofing adhered with hot tar and using either a mineral surfaced cap sheet or loose gravel applied to the final layer for fire protection.

Metacrylics coatings provide protection over failing or aged built-up roofing (BUR). BUR absorbs and holds heat, advancing the aging and weathering of the roof and eventually causing failure and leaks. Coating BUR with Metacrylics increases the efficiency of the building by reflecting heat and damaging UV rays. Metacrylics coatings also create a monolithic membrane, protecting the existing roof from damaging weather and moisture. Metacrylics coatings withstand ponding conditions and resist debris, protecting the existing membrane from water infiltration. By using Metacrylics to coat the existing roof, building owners and managers are able to avoid costly tear-offs and re-roofs.

Standing seam metal roofing is typically constructed of galvalume or galvanized steel.

Metacrylics coatings provide protection over failing or aging metal roofs. As exterior temperatures fluctuate, metal roofs expand and contract and experience movement that can wear down sealants protecting the roof from leaks. Coating metal roofs with Metacrylics reflective coatings lowers roof temperatures by reflecting UV rays and sunlight and are formulated to handle the movement of the roof without failing. Metacrylics coatings protect metal roofs from rust damage and is a more cost effective repair than a complete re-roof.

New construction wood decking is typically made of plywood or oriented strand board (OSB).

Class A Fire Rating over plywood requires either DensDeck® or Atlas FR Slipsheet.

Metacrylics coatings protect new construction plywood from weathering that can degrade the roof and cause leaks. Metacrylics coatings over new construction plywood reflects heat and UV rays, lowering roof and interior temperatures and potentially lowering utility costs.

Polyurethane foam roofing systems are sprayed in place and are typically used over built up roofing (BUR). Sprayed-in-place polyurethane foam (SPF) roofs must be coated in order to provide water proofing capabilities.

Metacrylics coatings provide protection to and extend the life of spray polyurethane foam (SPF) roofs. SPF roofs break down from weathering and often need to be coated and restored. Metacrylics coatings provide excellent resistance to weathering and ponding conditions.

Roof tiles, typically constructed of porous materials like concrete or clay, can be found throughout the US, but are much more common in warmer areas such as California, Arizona, Nevada, New Mexico, Texas, and Florida.

Metacrylics Roof & Tile Sealer protects and restores tile roofs. Aged or failing tile roofs absorb moisture, creating extra weight on the structure. Metacrylics Roof & Tile Primer penetrates and strengthens the surface, and Metacrylics Roof & Tile Sealer creates a seal on the surface, blocking moisture from the tile and eliminating the extra weight load. Roof & Tile Sealer is available in 36 colors.
