While most commercial and residential roofs are designed to handle loads in excess of what currently exists on rooftops, the current snowpack and potential for additional precipitation does increase the risk of collapses or other structural damage to properties. While there have been few issues reported in New York, there have been several reports of roof collapses across the Commonwealth.
Large, flat roofs are at greatest risk, especially those that are not properly draining. Property owners should be attentive to excessive snow accumulation, ice dams, and poor drainage on rooftops. For flat roofs with an existing ponding problem; a professional should be called to check the snow load and advise for the snow removal procedure if required. (Ponding is the collection of water which usually indicates a structural problem that can worsen with weight).
Homeowners and building owners who have concerns about excessive loads and/or the structural integrity of a property, should contact a professional/licensed contractor for assistance. Removing snow from a rooftop can be extremely dangerous, so it is best to rely on professionals.
