A Spray Polyurethane Foam Roof Coating Case History


Size: approximately 26,750 square feet
System: National Coatings AcryShield® SPF Roofing System

A building at the Google headquarters, otherwise known as Googleplex, in Mountain View, California was undergoing a major remodel and needed a new roof. They choose to restore their current roof with an AcryShield SPF Roofing System.

The AcryShield SPF Roofing System allowed them to gain additional roof insulation, increasing their R-Values to R-6 of insulation per inch. The new roofing system provided them with a fully adhered, energy efficient, highly reflective Cool Roof that will provide excellent energy cost-savings and increased employee comfort.

Google's original roof was aged and needed extensive repairs done and the AcryShield SPF Roofing System was able to provide them with a roofing system that met all their goals and offered a seamless, monolithic, waterproofed roofing membrane without an extensive and costly tear-off. They saved money and protected the environment by reducing already overflowing landfill waste.

Case History - Kaiser Permanente Antelope Valley Medical Office Building

Completed: June 2014
Contractor: Courtney Roofing
Size: approximately 50,000 SF
System: National Coatings SPF system with granule lock coat
Warranty Term: 20 years

Kaiser Permanente approached National Coatings requesting a roofing system with a 20 year warranty that could provide them with high reflectivity to combat the harsh Ultra-Violet rays from the high desert. It was also necessary that the roofing system delivers superior durability due to the roof having high foot traffic to be able to service the HVAC system and solar panels.

The goal was to combine both of these high reflectivity and superior durability properties into one system by embedding a course of granules between two coats of AcryShield A510 topcoat. This created a system where maximum reflectivity could be achieved while not sacrificing the high durability of a granulated surface.

Walkways were also installed by applying National Coatings AcryShield A550 for even more durability. The A550 was applied in a sand color to provide contrast creating a tan on white leaving Kaiser with very good looking rooftop.

Spray Foam Roofing Coupled with Roof Coatings Guarantees Energy Savings while Cooling and Protecting your Building

Operational and building maintenance costs are increasing year after year primarily due to energy related expenses constantly rising. Building owners are frequently looking for ways to lower these costs without compromising their buildings safeguard and defense. With energy being the greatest controllable operating expenditure to a building owner, we suggest saving money while cooling and protecting your roof with the AcryShield Spray Polyurethane Foam (SPF) Roofing System.

A Promising Solution

spray foam roofingThe quickest and best way to cut energy usage and related costs to your building when needing a new roof is to get an AcryShield SPF Roofing System. This system has excellent adhesion over existing Asphalt, BUR, Concrete, Metal or Wood membranes - eliminating the need for a costly roof replacement. The SPF system is spray applied, creating a seamless, custom-tailored waterproofing roofing system to meet your buildings specific needs. During application, your business operations are conducted as usual, avoiding any need for business closure. The AcryShield SPF Roofing System uses a durable roof coating; high in UV blocking pigments to give your roof the added protection it needs from the sun’s harmful and damaging UV rays.

How do Spray Foam Roofing and Roof Coating Work Together to Save on Energy?

The AcryShield SPF Roofing System uses topcoats with high solar reflectance, protecting the building by reflecting the sun’s heat away from the structure; therefore, reducing heat transfer into the building, keeping the inside cooler.  These coatings also have high thermal emittance properties, which allows the small amount of absorbed heat that was not reflected immediately, to be radiated back into the atmosphere, again lowering the ability to transfer heat to the inside.

While the solar reflectance and thermal emittance properties can greatly reduce the energy demands of cooling the building, these are just the benefits of using a National Coatings elastomeric roof coating.  Let’s take a look at the benefits of spray foam. The spray foam roofing provides high performance insulation to the roof. This reduces the buildings ability to lose or gain heat, keeping a constant ideal temperature inside the building with less need to use the air conditioning or heating systems.

Now that we know you can conserve energy with roof coatings and spray foam roofing separately, it is easy to determine that by combining the two, your building will conserve an even greater amount of energy. The AcryShield SPF Roofing System specifically can reduce your energy consumption and costs up to 30% per year. This is a huge reduction in cost based off California’s energy-efficiency movement - Flex Your Power© which states “A 30% reduction in energy consumption can lower operating costs by $25,000 a year for every 50,000 square feet of office space.” If you are interested in additional information on Spray Foam Roofing and the Benefits of Coating an SPF Roof, download our FREE Guide.
