In September, we asked for your questions on exposed-fastened (EF) roofing. Thank you for your responses! We collected them and thought we’d answer one of your questions today. A reader asked us why it made sense to install snow stops on an EF metal roof. If your building is in a snowy climate, installing a continuous snow fence, or discontinuous snow stops or snow guards is essential. For your system to be effective, however, the installation must be well-designed and by calculation – not by “guess and by golly.” There are common misconceptions around snow and metal roofing. So, today we’ll cover why a qualified snow retention system properly engineered for your specific installation is important to EF roofing in heavy-snow regions.
