FAQs
What are high-reflectivity roof coatings and how do they benefit metal roofs in Apison?
High-reflectivity (or "cool roof") coatings are specially formulated acrylic, silicone, or elastomeric finishes that reflect a large portion of the sun’s infrared and ultraviolet rays. When applied to a metal roof they can lower surface temperatures by 40–50 °F, reducing attic heat gain, easing the workload on HVAC equipment, and cutting summertime energy bills—an important advantage in Apison’s warm, humid climate.
How much energy can I save by adding a reflective coating to my metal roof?
Savings vary with roof color, insulation levels, and building use, but ENERGY STAR® studies show cool-coated metal roofs can deliver 7–15 % cooling-season electricity savings in the Southeast. Customers in Apison typically report payback periods of 3–6 years, especially on buildings with large conditioned spaces or older HVAC systems.
Will the coating prevent rust and extend the life of my existing roof?
Yes. Quality coatings act as a waterproof, UV-stable barrier that seals minor rust, pinholes, and seams. By limiting thermal expansion and protecting the factory finish from oxidation, a reflective coating can add 10–15 years to the useful life of a sound metal roof, delaying the cost and disruption of a full replacement.
Can every metal roof be coated, or are there conditions that make it unsuitable?
Most standing-seam and exposed-fastener metal roofs in good structural condition are excellent candidates. The roof must be free of extensive corrosion, have solid decking, and proper slope for drainage. Severe rust perforation, loose panels, or widespread moisture damage may require repairs or partial replacement before coating. A professional inspection is the best way to confirm suitability.
What is involved in the installation process and how long does it take?
Typical steps include: (1) power-washing and surface prep; (2) treating rusted areas with a primer or rust inhibitor; (3) sealing fasteners, seams, and penetrations; (4) applying one or two coats of the reflective membrane at the manufacturer’s specified mil thickness. A 5,000–8,000 sq ft roof can usually be completed in two to three dry days, with minimal disruption to occupants.
How much does a reflective coating system cost compared to roof replacement?
In Apison, professionally installed reflective coatings average $2.00–$4.50 per square foot, depending on product type and prep work. A full metal roof tear-off and replacement often runs $8.00–$12.00 per square foot. Coatings therefore cost 50–70 % less up-front, qualify for tax deductions as maintenance (consult your CPA), and may earn utility rebates for cool-roof installations.
