“Resilience” is a word we hear a lot about today in the world of commercial building design and construction. In general, it’s defined as the ability to stand up to a range of possibly severe weather conditions, and, when failure occurs, an ability to bounce back quickly. For a building to perform resiliently, as a whole, each of its systems also must embody these characteristics. Certainly, roofing is critical in this regard—after all, a roofing failure can make an entire building uninhabitable.
So, what, then, are the design factors behind a commercial roof’s resilience—and how does this relate to today’s other primary design goal, sustainability? “Sustainability is about thinking for the future, resilience is about resisting the current onslaught,” says James Kirby, AIA, building and roofing science architect with roofing manufacturer GAF. “So, resilience is the ability to stay in place, or being able to be repaired and replaced quickly.” For Kirby and other roofing experts, ensuring that ability to stay in place is dependent on the details— and detailing—of how that roof is designed. Kirby says this list begins with wind resistance, and the choice to design to a region’s wind code or go beyond those requirements.
Below you’ll find a few solutions we uncovered that specifically address the challenge of wind resistance.
New & Noteworthy
The stainless-steel roof topping historic Austin Hall on the campus of Sam Houston University in Huntsville, Texas, was only 10 years old when it began to fail, due to a seaming plan not appropriate to its low-slope design. So, though it was less than a decade old, it was recently replaced with a more appropriately engineered standing seam copper roof. The 238T and 138T symmetrical standing seam panels enable watertight performance because there is now interruption of sealant in the seam at clip locations.
EPDM roofing systems can be specified with a 55-mil fleece layer adhered as a backing for long-term protection against high winds, hail and punctures. These FleeceBack membranes are also well-suited for roof gardens and solar applications and can be installed with Flexible FAST adhesive, which reinforces the fleece for increased protection.
StealthBond metal roofing is attached using a proprietary adhesive, rather than mechanical attachment devices, and has received Miami-Dade County Building Code approval. The three-part system incorporates a base level of metal strapping that’s secured to the roof deck, the adhesive that’s applied to that strapping and, finally, metal roofing panels that are laid into the adhesive for penetration-free attachment.
A 22-year renovation of Christ Church Cathedral in Vancouver, British Columbia, was completed recently as workers finished their efforts replacing the 1894 structure’s massive roof. Designers with Vancouver’s Proscenium Architecture & Interiors, Inc., opted for standing-seam zinc for the complicated project, which required extensive detailing to address a large number of pitch changes and other transitions.
