A leading property insurer issues new guidance on Roof Snow Loading
Updates from ASCE have increased roof LIVE LOAD requirments.
New guidance represents increased awareness of:

Snow Water Equivalent (SWE) is a common snow pack measurement. It is the amount of water contained within the snow pack, and measured by melting a sample.
Fresh snow contains no more than 15% water. The rest is trapped air spaces.
Snow pack SWE increases in weight by absorbing water into these trapped air spaces.
Because this can happen quickly and dramatically, Facility Managers & property owners need to monitor roof snow loading in real-time.
The Deflection Monitoring Advantage
DMD-IP roof alarm systems by SRS provide REALTIME alerts when snow removal is needed.
It all depends on how much water is in it
Roof collapse losses exceed a
Billion dollars every year in the US
