TRA Snow and Sun recommends, for a number of reasons, that a licensed roofing contractor install snow retention devices such as snow guards and snow rail systems. Working on the roof is hazardous, and roofing contractors should be equipped with the proper safety devices to adequately work on the roof. Installing snow retention devices without permission from the original roofing contractor may void warranties that may be existing. Licensed roofing contractors have experience keeping a roof watertight, and are most suited to install snow guards and snow rail systems. We understand that even with these warnings, some homeowners would like to install their own snow retention devices. Installing snow guards in most cases is not difficult; homeowners are usually capable of performing the installation. It is critical, however, that snow retention devices are placed in locations approved by TRA Snow and Sun for snow guards and snow rail systems. Please call or email and ask for a FREE design for your snow retention project. We are willing to work with homeowners who wish to perform their own snow guard installation.
