Snow on Dish!!!!

My Sat. Dish is on my roof, too high to reach and sweep off the snow. I've lost all reception!  I'm not about to stand on a ladder in snow with a broom!! I need to have dish put at a lower area, so I can reach it to sweep snow off. I was told they can't move it, since it's on roof, now, and if they do, I'll be charged for moving the dish. So, when it snows and I can't sweep snow off..I'm without service and still have to pay regular price!! I am struck with this company and not happy one bit!!!!!
