Spray Polyurethane Foam or SPF roofing is excellent for restoring your current roof or as a new construction project. The foam used in these systems must be coated with a roof coating in order to provide the SPF roof with adequate protection needed from deterioration caused by the sun’s Ultra Violet (UV) radiation and water infiltration. 

Acrylic roof coatings are among the most popular in the roofing industry for protecting SPF because of their strength and ability to adhere to the spray foam. These coatings have a long history of success (check out our SPF Case Histories), high quality ingredients, and fire retardants that work together to construct a seamless, durable, and flexible membrane with excellent resistance to UV destruction and water penetration. 

When you combine SPF roofing with an acrylic roof coating system, you gain the strength and protection needed for the roof to function properly, as well as, excellent insulation, custom slope and superior reflectivity. These systems provide customizable levels of insulation to reduce heat loss and gain to the building, allowing your building to remain a consistent indoor temperature with less need to heat or cool the building. Custom slope can be created with the spray polyurethane foam for improved proper water drainage and ponded water protection.  High solar reflectance and thermal emittance properties gained from the acrylic roof coatings ability to reflect the sun’s heat away from the rooftop, lowers energy cooling costs and contributes to the reduction of heat transfer to the inside of the building, allowing the building to remain cooler on a hot day.

National Coatings has several SPF roofing systems coupled with acrylic roof coatings to provide all the benefits mentioned above. With over 33 years of proven performance, the AcryShield SPF Roofing Systems can decrease your energy consumption and costs. 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 more information on SPF Roofing or the Benefits of Coating an SPF Roof, download our FREE Guide.   

Spray polyurethane foam coating systems or SPF coating systems can greatly improve your buildings insulation and energy consumption while avoiding a costly roof replacement.

Improved Insulation
Spray polyurethane foam coating systems are excellent at insulating your building and sealing off airflow from escaping or entering the building. These systems are sprayed directly onto your rooftop (either as new construction or roof restoration) filling all cracks and openings on your roof to seal and prevent any heat loss to the building. SPF systems are excellent at resisting heat transfer with high R-values, reducing your energy consumption and allow your building to remain warmer in the winter and cooler in the summer.

Lower Energy Costs
There are a couple ways these systems allow you to save money on energy costs. The first is insulation. A building that is well insulated can save up to 20% of heating and cooling costs according to Energy Star. The second is reflectivity. Spray polyurethane foam coating systems should have a highly reflective roof coating to not only protect the foam from early degradation but also to reflect a majority of the sun’s heat away from the building, back into the atmosphere. This allows the building to remain cooler, absorbing a very minimal amount of heat on a hot, sunny day. Reducing the load on HVAC and heating systems while still maintaining a comfortable environment inside the building can drastically lower your energy costs.

Avoid Costly Roof Replacement
These systems are excellent for new construction but also for restoring and improving the condition of your existing roof to new. Spray polyurethane foam coating systems can be applied directly over aged, leaking, and failing asphalt, BUR, concrete, metal, modified bitumen, and wood substrates. They provide additional waterproofing layers and provide custom slope in necessary areas to eliminate drainage problems and ponded water issues. Your business stays open during construction as it is not necessary to tear-off or replace your existing roof. This will save a substantial amount of installation time and money, as well as, allowing business production to continue as usual with no loss of revenue.

National Coatings offers several different spray polyurethane foam coating systems to meet your buildings particular needs. These systems can range from ZERO VOC’s, extra foot traffic protection, ultra-high reflectance and more. Download our FREE SPF Roofing Brochure or contact us for more information.

Spray Polyurethane Foam (SPF) roofing provides excellent insulation and custom slope to avoid ponded water issues and improve water flow to drainage. SPF roofing systems require a roof coating to be applied over the foam in order to cover and protect the spray polyurethane foam from deteriorating due to the sun’s harmful UV rays. 

National Coatings’ offers several different types of spray foam coatings that have the ability to block and reflect essentially all of the sun’s damaging rays always from the roof top, protecting the SPF roofing system and building below.  These coatings are ideal for a newly constructed SPF roof, as well as, a SPF roof that needs a re-coat or restoration in order to prolong its roof life and lower roof maintenance costs. Our spray foam coatings all contain low levels of VOC’s, provide energy cost savings and create minimal disruption to the tenants and occupants inside the building during construction. These coatings have been successfully used on spray foam roofing systems for over 30 years, providing renewable and sustainable systems that are seamless and have outstanding waterproofing capabilities. 

Our spray foam coatings range from topcoats, base costs, quickset coatings and specialty coatings. Our topcoats are highly reflective, providing longevity and brightness with superior dirt pick up resistance and protection against biological attach such as algae. These topcoats exceed all ASTM D6083 requirements, offering excellent tensile strength, elongation and wet adhesion.  The AcryShield spray foam base coats are engineered to provide optimum and superior adhesion to SPF while adding additional waterproofing to your roofing system. Our quickset spray foam coatings come in base and top coats and are ideal for resisting early wash-off associated with heavy dew and light rain. We also have a range of specialty coatings that offer different advantages and protection to your spray foam roof including: low temperature flexibility, extra foot traffic and physical abuse protection, ultra high reflectance and coating for buildings and rooms where there is a reverse vapor drive (cold storage, food packing plants, etc…).
