Roof waterproofing is critical for structural integrity. Roofs are not just visual features; they fulfill a key role in facility protection. Whether flat or domed, every roof structure has a unique character. As the highest point of a building, roofs are continuously, year after year, bombarded by the elements, frequently giving way to costly leaks. MARIS POLYMERS offers liquid-applied Polyurethane roof coating systems for long-term protection of simple, and/or complex roof structures.

The MARISEAL SYSTEM® is the technologically superior roof waterproofing system – offering no hassle application, full certification, and guaranteed lasting results for your roof waterproofing needs. Ideal for repair and renewal, new vaulted or flat roofing designs, the MARISEAL SYSTEM® polyurethane roof coating (dependent on top coat) can also accommodate daily wear and tear from medium to heavy foot traffic.
