The snow removal system according to claim 1, wherein the at least one vibration imparting member comprises a plurality of vibration imparting members attached to the inwardly facing surface of the metal roof at spaced locations for vibrating the metal roof. 3. The snow removal system according to claim 2, wherein the plurality of vibration imparting members are actuated for a duration of time of between about 5 seconds and about 20 minutes. 4. The snow removal system according to claim 2, wherein the plurality of vibration imparting members are divided in to at least two separate zones, and the at least two separate zones are able to be actuated, independently of one another, for removing the frozen rain, ice or snow from the metal roof. 5. The snow removal system according to claim 4, the plurality of vibration imparting members, in the at least two separate zones, are coupled to remote a control device which is operable by an operator for removing the accumulated frozen rain, ice or snow from the metal roof. 6. The snow removal system according to claim 2, wherein the plurality of vibration imparting members each operate at a frequency between about 5 hertz and about 1400 hertz. 7. The snow removal system according to claim 2, wherein the plurality of vibration imparting members operate for a duration of time of between about 5 seconds and about 20 minutes. 8. The snow removal system according to claim 2, wherein each of the plurality of vibration imparting members comprises a motor which supports a rotatable cam, both the motor and the rotatable cam are accommodated within a respective housing, each respective housing is directly connected to the inwardly facing surface of the metal roof with at least the rotatable cam spaced from the metal roof, and a resilient member, which transfers the vibration to the metal roof to break up and separate the accumulated frozen rain, ice or snow, is located between the rotatable cam and the metal roof. 9. The snow removal system according to claim 1, wherein the at least one vibration imparting member vibrates at a frequency between about 5 hertz and about 1400 hertz. 10. The snow removal system according to claim 1, wherein the rotatable cam is coupled to a drive shaft, in an offset manner, so that rotation of the cam facilitates imparting vibration to the metal roof to at least partially break up and separate the accumulated frozen rain, ice or snow from the metal roof. 11. The snow removal system according to claim 1, wherein the at least one vibration imparting member further comprises a resilient member which transfers the vibration to the metal roof to break up and separate the accumulated frozen rain, ice or snow from the metal roof. 12. A snow removal system for removing accumulated frozen rain, ice or snow from a metal roof, the snow removal system comprising: a plurality of vibration imparting members each being fixed to an inwardly facing surface of the metal roof, at spaced locations, for vibrating the metal roof;a power source being coupled to supply electrical power to the each of the plurality of vibration imparting members; thea control unit communicating with the power source, and the control unit controlling a flow of energy from the power source to each of the plurality of vibration imparting members and actuating the plurality of vibration imparting members such that vibration is imparted, by at least selective ones of the plurality of vibration imparting members, to the metal roof to break up and separate the accumulated frozen rain, ice or snow from the metal roof so that the accumulated frozen rain, ice or snow slides off the metal roof due to the vibration and gravity;wherein each of the plurality of vibration imparting members comprises a motor which supports a rotatable cam, both the motor and the rotatable cam are accommodated within a respective housing, and the housing is directly connected to the inwardly facing surface of the metal roof with at least the rotatable cam spaced from the metal roof. 13. The snow removal system according to claim 12, wherein each of the plurality of vibration imparting members vibrates at a frequency between about 5 hertz and about 1400 hertz. 14. The snow removal system according to claim 12, wherein the plurality of vibration imparting members are actuated for a duration of time of between about 5 seconds and about 20 minutes. 15. The snow removal system according to claim 12, wherein the plurality of vibration imparting members are divided in to at least two separate zones, and the at least two separate zones are able to be actuated, independently of one another, for removing the frozen rain, ice or snow from the metal roof. 16. The snow removal system according to claim 15, the plurality of vibration imparting members, in the at least two separate zones, are coupled to remote a control device which is operable by an operator for removing the accumulated frozen rain, ice or snow from the metal roof. 17. The snow removal system according to claim 12, wherein each of the plurality of vibration imparting further comprises a resilient member which transfers the vibration to the metal roof to break up and separate the accumulated frozen rain, ice or snow from the metal roof. 18. The snow removal system according to claim 12, wherein the rotatable cam is coupled to a drive shaft, in an offset manner, so that rotation of the cam facilitates imparting vibration to the metal roof to at least partially break up and separate the accumulated frozen rain, ice or snow from the metal roof. 19.
