Has anyone ever experienced the problem of water collecting on the roof of a pop roof caravan especially during heavy rains ? 

Yes, easy way is to lower your roof front or rear ends and leave unil the roof is dry.

That is the time when I take the oppertunety to wash the roof properly.

I lower the entire roof, get onto the the roof with ladder from sides ONLY, because I am a lightweigt, which let scale go to maks - Just over 45kg.

Still, I spread my weight evenly to avoid to much wieght/side.

From the front or rear end you might injured yourself or possible cause damage to your caravan due to blindness spots.

Our previous caravan, a Sprite's pop up roof was a bit higher at the back meaning that when the caravan was quite level stationary, rain water would run down to the front. See if your's perhaps is constructed similiarl and if so, make sure it is quite level when set up. If not, a slight lowering of the front or back might still do the trick if you feel it is a problem. But I don' think it is a real pribkem. 

I don't think the motivation was for this purpose, but rather to put some downward pressure on the roof while towing. And welcome to the Forum.
