FEATURED TORCH-ON / SBS
This Burnaby commercial flat roofing project was performed in the Summer of 2018. The old torch-on roof was replaced with a brand new IKO Torch-flex torch-on roof system complete with a custom sloping package to eliminate areas with standing water and a base layer of insulation to improve the building’s overall R-value. Warranty was especially important to our client therefore IKO Industries provided their Diamond Shield upgrade which extended the material warranty to a more comprehensive 15 years. BestWest Group specializes in the replacement of commercial flat roofs, and offers a variety of solutions, all at a reasonable price.
