condensation in loft

[squeaker]

Hi i had a central heating fitted last march so this winter is the first time it has been used all the time,the flue for the boiler goes through my loft space and out the roof i had to go in the loft last week and noticed their is a lot of condensation and water droplets forming on the under felt of the roof which is dripping quite alot,should this be happening as it wasn`t their before i had boiler fitted any suggestions.
Thanks. :?:

Have the tanks been left in the loft, without lids/covers ? could be condensation/evaporation off the old tanks if they still have water in.

It's worth getting the boiler checked by a CORGI registered installer as the flue may have came apart.
