SEBS Material Commercial Roof Coating System – Key Benefits

Commercial roofing systems can be constructed with many different materials, all of which have their strengths and weaknesses.

One relatively new material is SEBS (Styrene Ethylene Butylene Styrene). While that might be a mouthful to say, here at Hyload, we like to refer to it as our fluid-applied product, HyKote™. Originally designed as an economical option for field coating metal roofs, SEBS products have been found to work well in a variety of applications.

What can a fluid-applied product provide in a commercial roofing project? SEBS offers benefits to both the building owner and applicator.


One of the significant benefits of a SEBS material roof coating system is its versatility.

Styrene Ethylene Butylene Styrene can be used as both a stop gap when restoring/repairing a roof made with other materials or as the top coat on a new commercial roofing project. Roofing materials that allow for a top layer of SEBS include EPDM, Granular surfaced SBS modified bitumen, PVC, Smooth Surfaced Asphalt BUR, Galvanized metal, Plywood, TPO, Smooth Surfaced Coal Tar Pitch BUR, Spray Polyurethane Foam, and Concrete.

SEBS roofing material is much stronger compared to other fluid applied coatings like acrylic or silicone-based products. Its durability withstands more adverse weather or heavier foot traffic before damage occurs.

In addition, SEBS allows for a quick fix or a long-lasting, weather resistant application that can help extend the life of your current roofing system. On average, SEBS roofing applications can last well over a decade before a major restoration or replacement needs to be considered.


Reflective Properties are an often-overlooked benefit of SEBS roofing coating systems.

These applications can produce significant (30-40%) cost saving benefits. Metal and other roofing materials absorb sunlight and heat throughout their life, raising internal energy costs of a building.

Often available in different colors, white SEBS applications help to reflect the sunlight best compared to other color coatings. White applications reflect over 80% of the UV rays and fall within the guidelines for an energy efficient building, according to the Energy Star Program. A white energy star rated roof will help the building get LEED points.

Over time, these cost savings can be a significant benefit to a building owner.

Low Permeability

Due to the coating application process, SEBS roofing systems are known for their low permeability.

Other roofing applications, like those applied in seams or strips, can have a higher level of permeability because moisture can filter through the seams over time. A SEBS system is applied in multiple cross hatching coats, avoiding potential weak spots found around seams or fasteners.

Due to its ultra-low moisture permeability, SEBS outperforms other materials in its resistance to pooling water along with algae and fungi.

Whether you are repairing a section or reinforcing the entire surface, a SEBS roof coating system offers an easy to apply, durable and energy efficient solution.
