Sarnafil Adhered Roofing Systems
Sarnafil adhered roofs are best for low sloped, uniquely shaped or pitched roof applications composed of non-nailable substrates such as pre-cast or pre-stressed concrete, cementious wood fiber or gypsum. They also work well over non-nailable substrates such as concrete, steel and wood decks. The EcoBond Roof which utilizes our water-based adhesive, Sarnacol 2121, also has a few cost competitive solutions becuase of its excellent coverage rate.
SIKA SARNAFIL - THE LEADING RESOURCE FOR ADHERED, ENERGY-EFFICIENT SINGLE-PLY ROOFING SYSTEMS
Adhered roofing systems from Sika Sarnafil provide building owners with an aesthetically-pleasing roofing application that delivers superior, watertight protection - this protection is the result of time tested membranes, hot-air welded seams and a wide variety of system configurations to match the unique needs of individual building designs.
COST COMPETITIVE SYSTEM
A Sika Sarnafil Adhered Roofing Systems can be cost competitive against EPDM and TPO. To learn more, contact us at 800-576-2358.
Sarnafil®-brand adhered roof systems attach securely over uniquely shaped roofs to combat mechanical stress from wind uplift. The systems eliminate sheet flutter and prevent ”billowing.”
Sarnafil membranes with feltback minimize the ”telegraphing” of substrates, resulting in a cleaner, more even appearance. In addition, adhered systems are suitable for ”non-nailable” substrates like concrete.
Adhered roofing systems are also an excellent choice when all other roof system components are adhered, as there are no fasteners puncturing the vapor retarder.

DECOR ROOF SYSTEMS
Adhered roofing systems are known for their aesthetically appealing appearance. This is especially important for building designs in which the roof is visible from the ground. Sika Sarnafil’s patented Décor Roof System uses vinyl profiles welded to the membrane surface to simulate the look of a standing-seam metal roof and is a popular option for steep slope installations. For this system, Sika Sarnafil produces membrane in seven standard colors and in an unlimited number of custom colors to meet design aspirations.
|Sarnacol® 2121||A water-based dispersion adhesive used within a Sarnafil adhered system. It is formulated for adhering PVC membrane to clean, dry, water absorbent, horizontal roof surfaces with slopes up to 10 degrees (2/12). See Technical Bulletins 03-09 and 04-09 for information on using Sarnacol® 2121 on flashings or higher slopes. For any other applications, contact Sika Sarnafil.||Yes|
|Sarnacol® 2170||A Solvent-based reactivating adhesive used with a Sarnafil adhered system and/or flashing details. It is also used to adhere flashings in Sarnafil waterproofing systems. It is formulated for adhering Sarnafil PVC membranes to properly prepared substrates such as wood, sheet, steel, masonry, concrete, insulation and approved coverboards.||---|
|Sarnacol® 2170VC||A solvent-based VOC-compliant adhesive used with a Sarnafil adhered roofing system and/or flashing details. It is also used to adhere flashings in Sarnafil waterproofing systems. It is formulated for adhering Sarnafil PVC membranes to properly prepared substrates such as wood, sheet steel, masonry, concrete, insulation and approved coverboards.||Yes*|
|*The U.S. EPA considers the solvent in 2170VC as "exempt," and therefore the product can be used in all jurisdictions operating under teh EPA guidelines. At this time, the SCAQMD does not recognize it as "exempt", and therefore the adhesive cannot be used in jurisdictions governed by their regulations directly(e.g., specific counties in CA). Not eligible for credits in LEED or Green Globes projects.|
THE INDUSTRY STANDARD
Sika Sarnafil is the undisputed leader in adhered thermoplastic roofing in the U.S., having provided commercial buildings through the years with unparalleled protection from the elements. The company has produced more than 15,000,000,000 sq. ft. of high performance thermoplastic membrane — with many of the company’s adhered roofing systems still performing after 25 to 30 years of service, in all types of climates. The company’s involvement with adhered roofing systems and the technology behind them goes back more than 45 years, and this expertise has led to innovative systems and products that fully address the needs of building construction.
LEADING IN THE WAY IN TECHNOLOGY
Sika Sarnafil was the first single-ply company to develop a membrane specifically for adhered roofing applications. The Sarnafil G410 membrane has a non-woven fiberglass mat for superior dimensional stability and a low coefficient of thermal expansion and contraction — factors critical to the service life of an adhered roof. The G410 membrane has the best dimensional stability of any single-ply membrane, based on testing to ASTM D 1204.
