Speaking after the race, Hamilton also hailed the support of the British crowd, which he claimed is better than anywhere else in the world.
He told reporters: "Our performance this weekend has been outstanding. The engineers and mechanics did a great job, so big thanks to all of them once again. And then the crowd... I mean, where do they all come from?
"It's absolutely amazing! Nothing we see in any other country even comes close - and that for me just shows the passion us Brits have for sport, regardless of the weather.
"This is beyond my wildest dreams, honestly. When I was younger I didn't see the other stuff that comes with being a Formula 1 driver."
Rosberg was demoted to third place at the end of the race after Mercedes were penalised for breaching rules on the use of team radio.
