My brother has 20" of snow on a 5/12 roof in Maryland, and rain has been forecasted for Tuesday.

Is the greatest danger from snow weight or from ice damming?

What would be the best strategy for the next 24 hours?

Thank you very much in advance.

A good snow rake, for sure.

Santa Claus and his reindeer with a snow plow blade on the bottom of the

OR

A remote controlled flying snow blower with GPS.

OR

Hydraulic cylinders that can flip the roof upside down.
