Commercial Roofing Systems

Unlike adhered roofing systems where the membrane is secured to the system using adhesive, the Sarnafast system secures the membrane using fasteners within the membrane seam overlap. Typically called an “in-seam" attachment system, after the plates and screws secure the edge of the membrane, the next sheet overlaps the fasteners and is made watertight by hot-air welding the seam. Unlike typical in-seam systems, Sarnafast uses a specially designed oblong shaped discs, “Sarnadisc XPN" instead of a standard circle plate for increased performance.

Unlike adhered roofing systems where the membrane is secured to the system using adhesive, mechanically-attached roofing systems secure the membrane to the system using fasteners. The Engineered System utilizes the Sarnafil S 327 roof membrane, designed specifically for mechanically-attached applications, and the galvanized steel bar,“Sarnabar", covered with a membrane cover strip.

Unlike adhered roofing systems where the membrane is secured to the system using adhesive, Sikaplan Fastened Systems secure the membrane using fasteners within the membrane seam overlap. Typically called an “in-seam" attachment system, after the plates and screws secure the edge of the membrane, the next sheet overlaps the fasteners and is made watertight by hot-air welding the seam. This type of system is considered one of the fastest most cost effective ways to install a single-ply roof. Below are some of the reasons why a Sikaplan fastened roofing system might be the best fit for your project.

Enhance wind uplift resistance while using fewer plates and fasteners with Sika Sarnafil's RhinoBond® System. RhinoBond is an alternative attachment system for Sarnafil and Sikaplan roof membranes. The RhinoBond system eliminates membrane fastener penetration by induction welding (fusing) the membrane directly to the specially coated plates used to secure the insulation or hardboard to the deck. The result is a roofing system that uses fewer plates and fasteners while enhancing the wind uplift resistance.

Why install a membrane still working out the kinks like TPO or a dark colored roof increasing your cooling bill in the summer, when you can install Sikaplan Adhered for the same price. The Sikaplan Adhered membrane, when used in combination with Sikaplan Single-Step Adhesive, is a very attractive, proven, cost competitive option for building owners who want a single-ply roof system but either need a lower cost system or might not own the building long enough to need the 25-30 year performance of a Sarnafil system. Single-step adhesive lowers costs by minimizing material usage through the use of recommended application methods, and by facilitating faster applications on top of the already cost competitive Sikaplan membrane. A win, win.

Roof refurbishment is increasingly more important in today's construction world as a sustainable way of extending an existing roof's lifespan. Buildings are typically built with a design that is intended to have a 50-year life. The roofs on the buildings will most likely need maintenance or refurbishment at certain stages throughout this lifetime to ensure continuous protection against water ingress and other climate-related exposures. One of the biggest advantages of liquid applied membranes is that the existing roof does not need to be torn off to be revived. 

Sika liquid applied membranes, Sikalastic RoofPro or Sikalastic RoofCoat, are applied directly over the existing roof surface. An inspection to ensure the substrate's integrity, a proper cleaning and appropriate primer and the roof can be given a new life with a warranty. The choice is yours to either use the RoofPro system fully reinforced, or ProTect or RoofCoat systems locally reinforced as needed.
