About DuraRoof

Product  Description     
  DuraRoof   is a patented 100% Acrylic Roof Coating designed to protect asphalt shingles and concrete tile roof surfaces. It has been tested to Category Five hurricane force winds and helps prevents shingle damages.   DuraRoof   eliminates Granular Loss and Algae Growth with just one application and will increase the life cycle of an asphalt shingle roof 5 to 7 years and can be reapplied every 5 to 7 years.   As asphalt shingles weather, they break down and absorb UV radiation which causes small fractures and loss of granules that protect the shingles. Untreated, these cracks allow water to penetrate to swell and shrink and over time the shingle would fail requiring replacement.   
  DuraRoof   increases a roof  life cycle because it provides a water-resistant barrier over your existing shingles and prevents water from adsorbing which prevents asphalt oils from leaching out.    DuraRoof  ™ adsorbs into the surface and helps eliminates damage and prevents wind uplift damage.
DuraRoof   is a patented formulation that is applied to asphalt shingle roofs that helps prevent hurricane wind damage and extends the life of your roof.  DuraRoof   acts as a barrier against wind and water which helps prevent roof failure. It dries clear, does not crack, will not turn yellow, and is guaranteed to prevent granular loss and algae growth.
DuraRoof   has been wind tunnel tested to withstand winds up to 130 mph and has been credited with saving numerous Florida homes by preventing roof damage from Hurricanes Francis, Jeanne, Wilma, Katrina, Ivan, and more. Over Twenty Million square feet of roof surface area has been applied to homes throughout Florida over the past 20-years and  DuraRoof   is the original clear asphalt shingle roof sealer that is guaranteed to perform.
DuraRoof   has a five-year warranty against algae growth and granular loss and is protected under US Patent Number 8,058,342.  DuraRoof   is cutting edge technology for asphalt shingle protection and preservation with a long list of satisfied customers. DuraRoof   is also excellent for use on concrete and tile roof surfaces for elimination of algae stains.
  DuraRoof     In order to completely understand the effect of  DuraRoof   on asphalt-based roofing materials, the mechanism of asphalt degradation must first be understood. Asphalt is a complex mixture of hundreds of aliphatic and aromatic hydrocarbons. As asphalt weathers, it breaks down chemically. The individual molecules absorb UV radiation from the sunlight. This energy causes the molecules to vibrate and ultimately to fracture.
DuraRoof   coated shingles show less degradation than un-coated weathered shingles and has formed a monolithic single layer membrane which is formed in-situ on the shingle. Some small fissures in the asphalt present at the time of  DuraRoof   application are actually filled, thus limiting further degradation of the shingles. These fissures would allow water to penetrate through the asphalt into the organic mat causing the shingles to swell and subsequently shrink when dry. Additional stress would develop when the shingle would freeze and thaw. Ultimately, the shingle would fail and the roof would leak, requiring replacement.
DuraRoof   increases the longevity by two separate mechanisms. First, asphalt is subject to degradation by UV radiation.  DuraRoof   is transparent to UV radiation and it does not absorb this intense radiation. It is not subject to polymeric degradation seen in less durable chemistries like aromatic urethanes and butyls.  DuraRoof   is formulated with UV blockers to protect the asphalt from degradation.
 A second mechanism of  DuraRoof   provides a water-resistant barrier over existing asphalt shingles.  DuraRoof   prevents contact of bulk water with the asphalt membrane, thus preventing low molecular weight asphalt fractions from leaching out of the asphalt.  DuraRoof   prevents intimate contact of water with the membrane and, more importantly, the reinforcing mat, thus eliminating the formation of ice and freeze/thaw changes in the membrane. Water infusion into the organic felt would also cause degradation of the mat via biological attack.
DuraRoof   acts more like a fully adhered functional membrane than merely a paint type coating. Studies conducted have demonstrated that greater than 75% of initial elongation properties were retained even after five years exposure.
 Laboratory testing performed to Florida Building Code TAS-100-95 standards has proven that a wind uplift reduction in excess of two hundred and fifteen percent (215%) is obtainable with a coverage rate of one hundred square feet per gallon (100 SF/Gal) with no water infiltration under the decking. Actual uplift reductions will vary depending on application methods, rates, and physical condition of the shingle surface being treated. Wind uplift is not covered under Enviroseal warranty, only algae growth and retention of granular. No additional warranties are expressed or implied.
