No satellite signal being received on certain channels.

I've been having this same problem for months but the number of channels affected is growing. If I do the Restart Box thing it helps for a while. Why is that? My dish is on top of my roof so I don't think a Sky engineer will go up there, that's also a reason why I've been reluctant to upgrade from my old sky+hd box. I pay a lot of money each month to not be able to watch a lot of stuff, or you'll be half way through a programme which then disappears.

@Madhouse1964 You would need to call out an independent local satellite company to check your dish, LNB, cable set up to get you fully functional again. . In addition, If it was possible for them to relocate the dish that would open up the possibility of switching to Sky Q.

You are correct. A Sky engineer wouldn't go onto a roof to examine your dish, however … 
Sky no longer deploy an engineer for Sky+ / Sky+HD issues. If your issue needs an engineer they will advise you of this and recommend you change your subscription to Sky Q, Sky Glass or Stream. If it’s a dish issue you will need to contact a local independent satellite engineer to investigate at your own expense. The exception to this is if you already have Sky Protect cover through Domestic and General Insurance whereby you can still contact D&G and request attendance.
