Seal to Roof Performance

Roofing shingles protect your home from the elements. One of the many elements that shingles protect your roof from is driving wind. Malarkey utilizes a specially formulated adhesive to seal shingles to the roof. Strong winds can threaten to lift shingles from your roof if they are not properly secured. In addition to being properly installed by a Certified Contractor, Malarkey uses lines of SEBS polymer modified asphalt sealant to help hold the shingle in place.

What makes SEBS so special?

SEBS (Styrene Ethylene Butylene Styrene) asphalt is engineered with adhesive properties to join the shingles together and cohesive properties to prevent them from separating from the roof. These properties are created because SEBS is an elastomeric block copolymer.

Ethylene-butylene midblock holds the chain togetherSEBS consists of SBS polymers linked together through a hydrogenation process, with an ethylene-butylene midblock. The high tensile strength of the compound is achieved from the reinforcing effect of the styrene bond, while the elasticity is a product of the thermoplastic ethylene butylene midblock. The blending of SEBS thermoplastic and asphalt yields a reinforced physical three-dimensional cross-linking network. The SEBS polymer is a true thermoplastic elastomer enabling expanding asphalt to contract to its original form. All of this makes SEBS a thermally stable and ultraviolet resistant polymer.

Malarkey’s SEBS thermoplastic modified asphalt excels in the most extreme environments and conditions. It is flexible down to 0˚F (-18˚C), and ensures that the shingle seal remains intact through freeze and thaw cycles. Test after test, SEBS radically eclipses other roofing systems in key areas of performance.

Why worry about the wind?

Strong winds associated with hurricanes and tornados can test the bond of a brand-new roof from a home in inclement weather areas. In fact, wind speeds between 65-85 mph – where tornado strength wind speeds begin – can tear off some shingles. Shingles with reinforced adhesion to the roof can also be relied on to stay in place and protect the home from a storm’s precipitation.

To provide homeowners with ways to safeguard their home from these extreme weather conditions, the Insurance Institute for Business & Home Safety (IBHS) created the FORTIFIED Home™ program to help strengthen homes from hurricanes, high winds, hail, and severe thunderstorms. The IBHS FORTIFIED Home construction standards and methods go beyond emergency preparedness and disaster preparedness. For instance, the FORTIFIED Home™ High Wind program “helps homeowners strengthen their home against severe thunderstorms, straight-line wind events, and high winds at the edges of a weak tornado.”
