Our final roof assembly is going up and this week it was getting some extra attention as video crews were on site to document it. Read on to find out why
Early on in the tendering process, Nelson Roofing and Sheet Metal from the Comox Valley proposed that they could handle the architectural sheet metal of our complex curved roof even beyond what the architects thought could be done. This week a video crew working for the Roofing Contractors Association of BC was on site filming the install and speaking to the crew about how it worked. When finished, this video will be used as part of a new RCABC training curriculum for architectural sheet metal.
Chris Smith from Nelson Roofing (back to camera) gets interviewed with the building behind him. In the top photo, one videographer is on the roof while another interviews a crew member.
We are really excited about the many secondary benefits such as this that our very advanced green building is already having on Vancouver Island. Our building is being constructed by highly qualified local trades crews. These contractors have a large proportion of journeymen and apprentices on site who are getting valuable experience working on a complex LEED project that will help facilitate the growth of the green building industry on Vancouver Island and the Sunshine Coast.
Although it won’t seem like it when done – this roof assembly is very advanced and represents new and increasingly common techniques. A “Blueskin” layer goes over the wood roof and provides the first layer of waterproofing and moisture protection. This is then covered by two more layers of installation, a felt layer and then standing seam sheet . Each sheet of has been precisely curved on the ground to meet the complex radius of the roof in 60′ lengths which must then be carefully lifted onto the roof without creasing the metal. The roofing is then secured to complete the install. Clips can then be attached to the ridges for fall-arrest systems and in the future to add photovoltaic panels.

Forming the complex curve of the roof. Not as easy as it looks.
Congratulations to the crew from Nelson Roofing and Sheet Metal on a great job and getting recognized by their peers for it!
