It is possible. We need to erect ladders at the location of the problem. Some shrubbery/landscaping may be unavoidably damaged. We also have to mechanically cut channels in the ice to allow water to flow. We are very careful but it is possible to damage shingles, especially on older roofs, during the process. Also, gutters can be damaged by excessive ice which is also beyond our control. Any damage occurring due to ice backup remediation would be repaired at additional cost during warmer weather.
Can your work cause additional damage?
