The Many Ways the HotSlot Roof Edge Ice Melt System is the best entry-level roof ice melt system:

Category	Criteria	HotSlot	Company “H-E”	Notes	Summit HotSlot Superior?
1. Energy Efficiency	Superior conductivity of materials?	Yes. Highly conductive aluminum alloy mass	No. 26 ga. steel is standard offering, an inexpensive and poor heat conductor	HotSlot’s aluminum alloy is 8 times thicker and much stronger than “H-E”.
	Superior conductivity throughout profile?	Yes. Excellent	No. Poor	HotSlot has 7 times greater thermal conductivity over H-E’s steel to better distribute heat
	Superior conductivity from heater cable?	Yes	No	HotSlot optimizes heat transfer directly to the top and drip melting surfaces.
	High mass, highly conductive valley system available?	Yes	No	See Radiant Edge Valley, a very effective and architectural heating element
	Eliminates heat loss due to fascia contact?	Yes	No. “H-E” is screwed directly to the fascia.	HotSlot has NO contact with heat-drawing fascia
2. User-friendliness	Easy ordering?	Yes. One shape, one piece panel system	Multiple parts required, each with different dimensions, angles, etc.,	Ordering HotSlot could not be easier.
	Simple design eliminates complexity of overall job?	Yes	No. Their manual states “Every roof is different.” Each roof needs custom angles, shapes, sizes, holes, foam variations determined	Company “H-E” has 400+ possible configurations from which to choose, greatly increasing margin of error.
	One size fits virtually all shingle roofs?	Yes	No	“H-E” recommends an electronic digital protractor be used to determine the “Various inside angles”.
3. Installation	Installation Costs	$	$$$	Installers claim HotSlot goes up in a fraction of the time of “H-E” or zig-zag heater cable
	Simple tuck in under shingles?	Yes	No. “H-E” requires multiple clamps to hold several parts in place. Two or more installers are usually needed.	HotSlot is simply tucked under shingles and easily fastened through pre-drilled holes. Cable slides in effortlessly after panel installation
	Gutters can remain in place during installation in most cases?	Yes	No	HotSlot fits over 90%+ of existing gutters
4. Architectural Appearance	Eliminates exposed fascia fastener bolt-on look?	Yes	No, “H-E” uses bulky hex-head screws though highly-visible front fascia plane	HotSlot’s matching low-profile rooftop fasteners virtually disappear
	Rigid extrusion to prevent “Oil Canning”?	Yes	No	“H-E”s system may “Oil Can” i.e., exhibit waviness inherent in lightweight sheet metal, which is considered unsightly by many
	Clean, safe fit into adjacent roofing?	Yes	No. Oil canning in sheet metal and slight angle errors can negatively affect shingle roofing and warranties	HotSlot’s rigid construction ensures perfect fit
5. Performance	Consistent heat across eaves	Yes	No. Their product has laps, gaps, and multiple layers	HotSlot’s one-piece heavy extrusion ensures balanced and effective heat distribution
	Rigid extrusion to maintain excellent heater contact and conductivity for life?	Yes	No. Expansion and contraction due to temp changes over time can fatigue soft metal.	When soft metals fatigue, their system can progressively lose heater contact and performance
	Design eliminates sharp sheet metal edges that can cut/damage heater cable?	Yes	No	“H-E” has sharp, raw sheet metal edges that can damage cable
