The main campus at Texas A&M boasts over 7 million square-feet of spray-applied polyurethane foam (SPF) roofing ā€“ almost no other system has been installed for the past 30 years. Why? Proven sustainability and energy efficiency.

    In 1985, Gerald Scott, P.E., then in charge of roofing and energy conservation within the Physical Plant Department, announced another benefit the university had been receiving from the SPF roofs: energy savings. Scott monitored energy savings on 27 different buildings on the campus that had received an SPF roof from 1980 to 1984. The results showed the university was able to cover the complete cost of the roof application through energy savings in an average of 4.5 years.

    Thermal transference has never been part of any roof test series so a set of test criteria was developed for this new class of roof system. EternaTile's average solar reflectance score of 0.43 which is over double the standard for today's Cool Roof technology!

    Preliminary testing was conducted on the thermal transference of the EternaTile roof system. These tests were performed "in house" and show a substantial benefit when using the EternaTile roofing instead of other traditional systems. See our findings here.


    Solar Eterna"Gā€ eliminates the need for a separate solar panel system on the roof or yard area. Eterna"Gā€ contains 3 main elements never comprised before in a single roofing tile, power generation, insulation, and weather protection. Factor in the electricity a new Eterna"Gā€ roof generates, added insulation value, extra longevity, and payback time/Total Cost of Ownership (TCO) is dramatically reduced by comparison.

    Every EternaTile roofing system will offer a lifetime guarantee only when installed by a certified technician. The insulative, lightweight, foam core combined with a top coating that's nearly impervious to fire, UV rays, pealing, chipping and more, plus it renders a structure with the last roof it should ever need. Due to its durability and longevity, EternaTile offers the best return on investment in the roofing industry to date. Initially it may exceed the material costs of traditional tile, slate, wood, or asphalt shingle systems, but its easy installation greatly reduces the labor needed, so the overall EternaTile installation competes admirably.

    An Eterna"G" solar roofing system may fully pay itself off in less than 10 years when considering current substitutes, tax credits, and local and federal rebates. Even the EternaTile non-solar system under the same circumstances pays for itself in less than 20 yrs thereafter earning revenues and/or savings for 40 or more years. EternaTile enhances the value of the property and the performance of any energy saving article installed in any structure (heating and cooling units, windows, wall/floor insulators, etc.) as well as provides an endless supply free energy for new AC/DC items like electric cars, tanning beds, hot tubs, etc.

    EternaTile is the ultimate compliment to any sloped roof be it a residential or commercial property. It not only increases the structure's value, it also offers the most energy efficient roof system available simply by controlling attic temperature in all weather climates saving end users up to 38% in heating and cooling expenses.

    The Florida Solar Energy Center has completed a study on energy savings on residential structures in 13-cities in the USA and the findings are record breaking. Homes built before the year 2015 can save up to 38% on utilities per year! These results are contingent on vented and unvented attics for poorly insulated to extremely insulated homes in all national climates. See their full study here at Simulated Energy Savings.

    EternaTile, as modeled, offers great potential to reduce energy usage in many older homes by creating a much cooler attic during the sunny months of the year.

    Summer attic temperatures are greatly lowered with the EternaTile foam roof. Peak attic temperature reductions ranged from 40 to 78 degrees. EternaTile's average solar reflectance of 0.43 is a drastic improvement over any typical shingle or tile roof.

    Furthermore, the foam roof configuration has R-14 level of protection from the outside area, into the attic. Some cities were modeled with internally foam sealed ventless attics containing ductwork for thermal regulating the attic space as one would the rest of the home. In all cases a significant BTU reduction benefit was rendered in annual seasons.
