Roof heater cable extension?

We have a vacation place in the Poconos which had an awful ice dam this winter on a certain part of the roof doesn't get any sunshine. I picked up (only) 50 ft of fancy self-regulating heater cable at a good price. 2 questions: 
1- the GFI outlet is about 12 feet from the roof, and I don't want to waste that length of the heater cable. Can't find a decent short length of outdoor 12 gauge extension cord. If i cut and shorten a 25' extension cord, how to best waterproof it so I don't short the GFI? splice, wrap with tape and cover with silicon caulk? Should I do the same to where the extension cord joins with the heater cable cord? 

2- How expensive are these to run? like a toaster all winter?? Even though they can be set to come on only below freezing... that still means all winter long. The heater cable runs off a dedicated GFI circuit breaker, but we're not at the house all the time to monitor when an ice dam is forming. Any ideas?

As to #2, deicing cables use about 6W to 9W 

per foot, so your 50 ft cable would use maybe a maximum of 450W, or a miniumum of about 300W. Same as leaving 3 or 4.5 resistive 100W incandescent bulbs on. Said another way, in one day you'll use a maximum of 10.8 kW-H or less. Look at your existing electric bill and see how many kW-Hours you use now in a month.
