Many people are looking for the most inexpensive and easiest to install heating cable for their roof which is what is called constant wattage roof cable. It is a smaller cable that can be use with shingle piercing roof clips as opposed to self-regulating cable which requires clips that are glued and/or nailed and screwed down. There are six manufacturers of constant wattage cable and we sell four of them. EasyHeat makes ADKS, Wrap-on makes their grey and black cables, King Electric makes their CWR and Danfoss makes their RX-C cables. There are also a couple of other brands we do not sell called Frost King and M-D Building Products which are similar.
