Went up into the loft yesterday to retrieve Christmas decorations and
found that the tops of the spars on the north facing pitch of the roof
were damp/wet. If I touched the felt then water drops appeared.

The south facing pitch appeared to be dry.

Could it be condensation caused by the colder north facing tiles which
might, possibly, still have snow on them? I increased the insulation
quite significantly earlier in the year.

TIA

You've made the loft a lot colder (less heat escaping from below),
making condensation more likely.

You need to ventilate the loft space better.

Maybe its a leak a cheap moisture meter makes it easy to find. warm
air infiltrating or temp allow condensation which leads to mold the
rot, if its only one area maybe its a leak

The first thought was 'leak', possibly from one of the joints in the
ridge tiles, but it's several spars that are wet on the faces that touch
the felt.

probably condensation.

cold/no airflow.

put a vapour barrier om the celing, and check eaves vents
