System with non-Newtonian dilatent fluid to stop hail damage

A roof protecting system for protecting a roof of a building against damage from hail, the system comprising:

• a roof covering structure adapted to cover at least a portion of the roof;
• the roof covering structure being capable of holding a non-Newtonian dilatant fluid;
• a deployment system to dispose the roof covering structure onto the roof;
• and
• a delivery system for delivering the non-Newtonian dilatant fluid to the roof covering structure, wherein the delivery system includes
• a storage volume for a solid, wherein when the solid is combined with a liquid, the non-Newtonian dilatant fluid is formed;
• a first conduit for delivery of the solid to a control system;
• and
• a second conduit for delivery of the liquid to the control system;
• wherein the control system controls delivery of the solid and the liquid to a plenum in proportions that can be mixed to form the non-Newtonian dilatant fluid;
• wherein the solid and the liquid undergo mixing to form the non-Newtonian dilatant fluid;
• and
• wherein the roof covering structure is fluidly connected to the plenum to receive the non-Newtonian dilatant fluid from the plenum.
