Coating application is a sound choice. Think green. A major re-roof including a tear-off generates massive amounts of waste and often much of that material is non-recyclable. Coating is renewable. When weathering wears down the thickness, new coating can be applied over it. This may be 10, 15 or even 20 years from now. Reflective coatings reduce energy consumption and lower surface temperatures. Silicone coating is high-solids, compact, efficient to transport and VOC compliant.
