Seismic design considerations for commercial roofs in Vancouver

Vancouver lies near the Cascadia fault (aka Cascadia subduction zone) which is the 2nd largest active fault in North America. It has the capacity to generate the largest, most damaging earthquakes in the world. In fact, most of us have heard we’re due for “the big one”, a potential magnitude 9 quake, sooner than later. However, we also get multiple earthquakes every day here in southwestern BC, 1296 and counting this year alone. Including that magnitude 4.7 we all felt back in February.

So to minimise damage, injuries and loss-of-life, it’s critically important to keep our buildings up to code and prepared to withstand seismic activity in addition to wind, rain, storms, and blistering or freezing temperatures. As a long-time provider of commercial roofing services in Vancouver, we are well-versed in seismic building codes and keep up-to-date on all changes.

Seismic design considerations for commercial roofs in Vancouver include using strong, flexible, and lightweight materials during retrofit, repair or replacement of a commercial building roof. Examples include metal roofs, which are comparatively lightweight, strong and shear-resistant. Single-ply membranes like TPO & EPDM, are strong, flexible and lightweight. Their superior flexibility helps absorb seismic energy. Additionally, they can stretch without tearing, leaving a roof intact after an earthquake event.

Fastening systems and connections can also be upgraded and reinforced to improve building durability under seismic stresses. Professional inspections will pinpoint necessary upgrades to ensure code compliance.

To maximise your building’s performance, it’s crucial to hire professional commercial roofing services in Vancouver to perform this type of work, from the initial inspection process through the installation of the best seismic resistant roofing system for your commercial property.
