Roofing, Safety, and … Beer?

Jacksonville, FL – James Harris from Sika Roofing showed us around Anheuser Busch’s new addition to their canning facility in Jacksonville, Florida. While the original plant was built 10 years ago, Anheuser Busch is building a second facility next door to meet customer demands. Anheuser Busch is using a Sarnafil Roof System to cover the roughly 200,000 square foot roof of this new facility.

The spacing of the plates can be changed depending on the roof’s design.

James explained to us that there are three primary ways to install a Sarnafil Roof. The first involves using glue to adhere the roofing membrane to the insulation. The second involves mechanically attaching the Sarnafil membrane using plates and screws. The Anheuser Busch facility is using the third option, a Sarnafil RhinoBond System which is neither an adhered nor a mechanically-attached system but sort of utilize aspects of both. While all options provide a long lasting and durable roofing system, the RhinoBond system improves wind uplift performance to combat the unpredictable Florida weather.

In the RhinoBond system, plates are placed strategically across the Sarnatherm insulation and secured to the deck. These plates are coated in PVC that allows them to bond to the Sarnafil membrane. Using a RhinoBond induction welding tool, the metal in the plate heats up and bonds the bottom side of the Sarnafil membrane to the top side of the PVC coated plate. Then a magnet is placed on top of the Sarnafil membrane to help with the bond and dissipate the heat. Finally, the roof membrane seams are hot-air welded together using an automatic welding machine, or a hand-held welder for more intricate work. This makes the new system water-tight.

Sarnafil membranes come in 100 foot long sheets.

With the RhinoBond system, fewer fasteners are needed at the roofs edge compared to a typical mechanically-attached system. This can make the system cost-effective while still being able to handle increase wind pressure which is especially important in Florida, as hurricanes can carry extreme winds.

While on the roof, we also learned how important the issue of safety is. Since a worker falling off the roof is a very real scenario in roofing construction, the project managing firm Haskell has implemented a 15 foot safety perimeter around the roofs edge as part of their safety initiative. Any worker in this area has to have a safety harness on and be attached to an anchor point in the roof. We even got the opportunity to sit in on a safety orientation seminar, which promoted attentive working and speaking out about unsafe practices. The unpredictable Florida weather also plays a role in Haskell’s safety protocols, as workers need to exit the roof if lightening is approaching.

Barber and Associates, Inc., the roofing contractor doing the Sarnafil installation will finish the roof by the end of August. In the meantime, beer production is not being affected by the installation and Budweiser product sales will continue as usual!

Look how smooth the final roof looks!
