Snow & No Signal - Need opinions please

[m4p]

I have the Slimline dish with 5 LNB. We have been getting some wet snow here and last night my signal went out completely, all signals read at zero. So I took a long pool brush I have & brushed the snow off the dish very carefully (the dish is on the roof). Picture came back. Then today when I got home from work, picture was badly pixelated, so brushed the snow off again, and picture came back. There was not a lot of snow at all, but a wet snow sticking to the dish.

I understand that spraying a silicon spray on the dish can help, or a dish heater. I talked to Directv & they told me that if I have a weak signal to begin with that any snow will cause problems. So I set up an appt for them to re-peak or re-align the dish for Saturday. But now I'm wondering if that would help or not. I took 4 pics of all the satellite signals and wonder if anyone wouldn't mind looking at them to tell me if my signal is good as is, or could it be better with a dish realignment. Here's the link (you don't have to sign in or sign up to view the pics, just click on View Slideshow. There are 4 pictures:

Thanks! Any help would be greatly appreciated.

Your 103(b) signals are just a bit low, so peaking the dish will probably help.

But snow on the dish will certainly affect your reception.

Thanks, Litzdog911, for the reply. We've had snow before on our previous dish and never had such a bad problem. Maybe there's something about the way the Slimline is shaped that holds snow more. I think I"ll keep the appt for the re-alignment and hope that helps some, and will also try spraying with silicon.

I ordered a coffee mug with your signal strength levels on it.
