Abstract
A method prevents ice dams on an outside surface of a slanted roof of a building. The building has an outside wall. The roof extends over and beyond the outside wall in an outward direction. The method includes placing a first heating device between the roof and the outside wall. The heating device extends beyond the outside wall in the outward direction. Heat from the heating device is used to melt frozen precipitation on the outside surface of the roof.
Claims14
A snow-melting apparatus for preventing ice dams on an outside surface of a roof of a building, an outer edge section of the roof extending over and beyond an outside wall of the building in an outward direction, the roof having a direction of incline, a plurality of elongate rafters being attached to an inside surface of the roof, at least two of said rafters extending substantially parallel to each other and to the direction of incline of the roof, said apparatus comprising:
- a heat conduction device comprising:
- a substantially planar body portion formed of a substantially thermally conductive material and having two opposite ends, a first side and a second side, said second side being opposite said first side, said first side being configured for contacting and transferring heat to the inside surface of at least the outer edge section of the roof;
- and
- two substantially planar side portions extending from said body portion, each said side portion having two opposite ends, a first of said ends being attached to a respective said opposite end of said body portion, said side portions being configured for at least one of simultaneously engaging and being simultaneously connected to respective ones of two adjacent said parallel rafters;
- and
- a heat source attached to said body portion of said heat conduction device.
A snow-melting apparatus for preventing ice dams on an outside surface of a roof, said apparatus comprising:
- a heater wire arranged in a serpentine pattern, said heater wire being configured for being attached to an inside surface of the roof;
- and
- a power supply electrically connected to said heater wire.
A snow-melting apparatus for preventing ice dams on an outside surface of a roof of a building, an outer edge section of the roof extending over and beyond an outside wall of the building in an outward direction, the roof having a direction of incline, a plurality of elongate rafters being attached to an inside surface of the roof, at least two of said rafters extending substantially parallel to each other and to the direction of incline of the roof, said apparatus comprising:
- a heat conduction device comprising:
- a substantially planar body portion formed of a substantially thermally conductive material and having two opposite ends, a first side and a second side, said second side being opposite said first side, said first side being configured for contacting and transferring heat to the inside surface of at least the outer edge section of the roof;
- and
- two substantially planar side portions extending orthogonally from said body portion in a direction substantially opposite said first side of said body portion, each said side portion having two opposite ends, a first of said ends being attached to a respective said opposite end of said body portion, said side portions being configured for at least one of simultaneously engaging and being simultaneously connected to respective ones of two adjacent said parallel rafters;
- and
- a heat source attached to said second side of said body portion of said heat conduction device.
A snow-melting apparatus for preventing ice dams on an outside surface of a roof of a building, an outer edge section of the roof extending over and beyond an outside wall of the building in an outward direction, the roof having a direction of incline, a plurality of elongate rafters being attached to an inside surface of the roof, at least two of said rafters extending substantially parallel to each other and to the direction of incline of the roof, said apparatus comprising:
- a heat conduction device comprising:
- a substantially planar body portion formed of a substantially thermally conductive material and having two opposite ends, a first side and a second side, said second side being opposite said first side, said first side being configured for contacting and transferring heat to the inside surface of at least the outer edge section of the roof;
- and
- two substantially planar side portions extending orthogonally from said body portion in a direction substantially opposite said first side of said body portion, each said side portion having two opposite ends, a first of said ends being attached to a respective said opposite end of said body portion, said side portions being configured for at least one of simultaneously engaging and being simultaneously connected to respective ones of two adjacent said parallel rafters;
- a heat source attached to said first side of said body portion of said heat conduction device;
- and
- a layer of thermal insulation attached to said second side of said body portion of said heat conduction device.
A snow-melting apparatus for preventing ice dams on an outside surface of a roof, a plurality of elongate rafters being attached to an inside surface of the roof, at least two of said rafters extending substantially parallel to each other and to a portion of the roof to which the parallel rafters are attached, said apparatus comprising:
- a heat conduction device formed of a substantially thermally conductive material, said heat conduction device extending between and being connected to two adjacent said parallel rafters, a planar portion of said heat conduction device being disposed below, substantially parallel to, and closely adjacent said inside surface of the roof, said planar portion also being disposed above an underside of at least one of said two adjacent parallel rafters;
- and
- a heat source attached to said heat conduction device.
A snow-melting apparatus for preventing ice dams on an outside surface of a roof, a plurality of elongate rafters being attached to an inside surface of the roof, at least two of said rafters extending substantially parallel to each other and to a portion of the roof to which the parallel rafters are attached, said apparatus comprising:
- a heat conduction device formed of a substantially thermally conductive material, said heat conduction device extending between and being connected to two adjacent said parallel rafters, adjacent said inside surface of the roof, said heat conduction device including:
- a substantially planar body portion having a first side and a second side, said second side being opposite said first side, said first side being configured for engaging and transferring heat to the inside surface of the roof, said body portion having two opposite ends;
- two substantially planar side portions extending orthogonally from said body portion in a direction substantially opposite said first side of said body portion, each said side portion having two opposite ends, a first of said ends being attached to a respective said opposite end of said body portion, each said side portion being configured for at least one of engaging and being connected to a respective one of said two adjacent parallel rafters;
- and
- two substantially planar wings, each said wing extending orthogonally from a respective said side portion, said wings extending in substantially opposite directions from said side portions, each said wing having a proximal end attached to a second of said ends of said respective side portion, each said wing being configured for being attached to a respective one of said two adjacent parallel rafters;
- and
- a heat source attached to said heat conduction device.
