Roof Coatings - A Roofing Material that Saves You Money

Posted by Nicole Gale on Tue, May 06, 2014 @ 11:00 AM

Roofing Material Elastomeric roof coatings are excellent at sustaining and restoring existing aged or leaking roof membrane. All roofing materials require proper application and maintenance to perform to their fullest – roof coatings are no different. When applied and maintained properly, elastomeric roof coatings offer cost savings benefits by prolonging your roofs’ life and reducing energy costs and usage. 

Prolonged Roof Life

Elastomeric roof coatings are ideal for restoring and maintaining Asphalt roofing (BUR and Mod Bit), Single-Ply roofing (TPO, EPDM, PVC and Hypalon), Spray Foam roofing (SPF), Metal roofing and Concrete roofing.  The coating systems allow the roof to be renewed and restored – achieving a watertight, fully seamless, brand new roof membrane. AcryShield roof coating systems are the leading coating systems in the industry allowing you to restore your roof indefinitely. When proper roof maintenance is performed, a fully restored roof coating system can be re-coated every 10-15 years, allowing you to avoid a costly roof tear-off forever.

Reduced Energy Usage and Costs

Roof coatings with high Ultra-Violet (UV) blocking pigments are the best choice for a roofing material that needs to provide you with durability and protection from the sun’s harmful and damaging UV rays and heat.  Roof coatings containing large amounts of these UV blocking pigments allow the sun’s heat to be reflected back into the atmosphere (a process otherwise known as solar reflectance) without the building absorbing much of the heat (a process otherwise known as thermal emittance). This keeps the temperatures inside the building down. The greater ability to reflect the sun’s radiation, the cooler the building remains, and the less air conditioning is needed to create a comfortable temperature for the occupants inside. The Cool Roof Rating Council (CRRC), an organization that accurately and credibly evaluates solar reflectance and thermal emittance of roofing materials, has rated our AcryShield roofing products highly - check the ratings out! The AcryShield roof coating line has be proven to lower energy consumption and save on air conditioning costs. 

After the National Coatings' Cool Roof was installed we definitely noticed a difference in building temperature. It's not a marginal difference, either. It is between 15-20 degrees cooler inside the warehouse and store." Jerry Moore, Facilities Director at Harbor Freight Tools

UL Listings...What They Really Mean for Roofing Products

Posted by Nicole Gale on Thu, May 01, 2014 @ 10:00 AM

UL Roofing ProductsRoofing professionals: architects, consultants, specifiers and contractors have all seen the ubiquitous UL logo on product literature, approvals, roll goods, membranes, accessories and coating products.

Underwriters Laboratories Inc. (UL) is an independent product safety certification organization. Established in 1894, the company has its headquarters in Northbrook, Illinois. UL develops standards and test procedures for products, materials, components, assemblies, tools and equipment, chiefly dealing with product safety.

While the UL logo provides some reassurance regarding fire safety of roofing materials, there is often some ambiguity about what REALLY is listed on the UL website.  UL tests SYSTEMS, not individual roofing components.  The presence of the UL logo merely shows that a product, e.g. rolled roofing material, membrane, or coating is part of a tested system that meets the UL criteria. 

This means it is imperative that the specifier, consultant, designer of record, or contractor must use all the components in that rated system.  Merely incorporating some of the components or "cherry picking" components is not permitted and violates the intent of the UL listing.

National Coatings Corporation has an extensive list of UL listings. 

These can be found in the UL website: click here.

One most notable listing is the National Coatings approval where AcryShield coatings are applied over existing roofing systems.  Consider a building owner who states that they have a UL listed roof, and are concerned that applying a maintenance coating will void the UL listing.  The following is extracted from the National Coatings Corporation UL listing:

14. Deck: NC or C-15/32

Incline: See Note 1

Existing Roof System: - Any EPDM, TPO, Hypalon, PVC, TPA, modified bitumen or CPE single ply membrane system, mechanically fastened or fully adhered, non-insulated or insulated.

Surfacing: - "AcryShield", 1½ to 6 gal/sq. May be reinforced with fabric (3 oz/sq yd max).

Note 1: Classification (A, B or C) and maximum 2-in incline for membrane manufacturer's insulated or non-insulated Roofing Systems (TGFU) Certification.


The above all encompassing listing allows for the use of AcryShield roof maintenance coating while maintaining the original UL listing for the existing roofing assembly.

In summary, when considering a reroofing or recoating project, be sure to understand the specifics of the full roofing assembly and specify the appropriate system that conforms to the building owner, and local code requirements.
