I represent a condo corp that in 2005 had the roof, approximately 9000sqft done in a sprayed foam roofing system supplied and installed by western urethane out of Saskatoon. There were weather delays and payment delays on the project. I became the building operator in 2006. It was in the summer of 2007 that I began to notice large sections of the top coat were peeling off. It took 2 years and numerouse emails and telephone conversations to western urethane to return to repair the top coat under warranty. This was done in 2008. Two years later after the warranty repairs were completed, the top coat began peeling again worst then before.. I strongly believe that western urethane uses a poor performing product and and even poorer application techiniques. Now the condo corp has to replace the roofing system just after 8 years. I would strongly not recommend using western urethane for any projects.
