Applying a reflective coating extends your roof's lifespan by reducing heat transfer into your building and minimizing thermal shock caused by expansion and contraction of the roof membrane. This process also helps prevent leaks, lowers cooling costs, and enhances the overall appearance of your roof.

Nearly all roof types are suitable for coating applications, including metal roofs, spray polyurethane systems, single-ply membranes, modified bitumen, and built-up roof (BUR) systems. Ballasted and gravel-surfaced membranes generally require special treatment before coating can be applied. Advanced Roofing Technology will help you find the right solution for your roof.

Various reflective roof coatings provide different reflectance values. The most common are white coatings, which typically consist of acrylics, urethanes, silicones, SBS, SEBS, and similar materials. Aluminum coatings are also available and are commonly used with asphalt-based roofing systems.

Roof coating application can be completed using spray equipment, rollers, or brushes, depending on the project requirements and roof configuration.

While primers cannot replace proper cleaning procedures, they may be necessary depending on your roof substrate and the coating type being applied. Contact your coating manufacturer to determine their specific primer requirements.

The appropriate coating thickness varies based on the manufacturer's specifications and your project requirements. Contact the coating manufacturer for guidance when determining the proper application rate.

Proper roof preparation requires thorough cleaning followed by complete drying. This step is essential for successful coating adhesion. When pressure washing, exercise caution to avoid damaging lap seams or compromising the existing roof membrane, particularly at adhered seams. Always follow the specific preparation guidelines provided by your coating manufacturer.

Coating a new roof is advisable if you want to incorporate a highly reflective surface to lower energy expenses and extend the roof's service life. Be aware that applying a coating during an active warranty period may affect existing warranty coverage, so review your warranty terms before proceeding. A reflective coating significantly reduces heat absorption by the roofing system.

A reflective coating does extend roof longevity. The coating serves as the primary defense against UV damage and water infiltration while reducing thermal shock from expansion and contraction cycles.

When properly applied, a roof coating can extend your roof's service life by 10 years or more, according to established performance data. Actual longevity depends on the coating type, environmental conditions, and the thickness of the applied coating film.
