Overview


Engineered Mechanically Attached Roofing System

HIGH WIND PERFORMANCE MECHANICALLY-ATTACHED SYSTEM

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 the Sarnafast System where the fasteners are along the membrane seam (in-seam), the Sarnabar and cover strip can be placed anywhere on top of the membrane depending on the designers specifications (out of seam). This provides design flexibility and protection against wind that no other roofing system in the industry is capable of. It is guaranteed to meet and exceed even the toughest of design criteria.

Below are some of the reasons why the Engineered System might be the best fit for your project.

ENGINEERED SYSTEM BENEFITS:
  • High-wind uplift resistance
  • Customizable to meet wind requirements
  • Perfect for high rise and coastal buildings
  • Proven Performance Sarnafil Membrane
  • Best for low slope applications
  • Eliminates sheet flutter and “billowing”
PROJECTS WHERE A HIGH WIND SYSTEM SHOULD BE CONSIDERED

The National Oceanic and Atmospheric Administration’s National Weather Service states that “a high wind event has occurred whenever sustained winds of 40 mph or more, or a peak gust of 58 mph or more, has been reported from reliable observing equipment.” A roofing system will truly be tested when it experiences multiple wind events over time in the most extreme weather conditions.

High wind events are not just limited to those buildings that are located near the coastline or in tornado prone areas. Consider the following criteria when determining if your building should have a roof system designed to resist high wind loads.

  • Building height of 70 feet or taller
  • Location near any large body of water (coastal or inland)
  • Location within hurricane prone areas
  • Building codes requiring a roof to withstand winds greater than hurricane velocity (74 mph)
  • A desire for long term performance and complete security
