Help and advice please :Loft / attic ventilation, high humidity

justwondering25

I had a new roof fitted last year and I have been checking the humidity around the house with a fairly good Bluetooth humidity sensor, it connects to my phone and reports on humidity, heat and calculates the dew point and it keeps a detailed record 

Anyway I had some condensation issues in the front bedroom from the last tenants, but they had been drying lots of clothes on the radiators....

Fitted a Nuaire PIV unit in the loft, the type without the heater. 

Kitchen and bathroom both have Nuaire humidity sensor extractor fans. 

Anyway, fully redecorated, no signs of damp behind the wallpaper.

Anyway, used the meter around the house, found the front bedroom humidity to sometimes be over 60.

Then I read about possible issue been with the roof / attic pitched roof 1930's 3 bed semi.

The roof has been fitted with red standard type tiles, breathable membrane, two air inlet tiles, seem oddly placed one on front the other on the side of the house roof.

The attic is fairly empty and has a insulated cover to the hatch. 

My meter is reading as humidity of 80 current humidity outside, according to checking the weather using my post code is 79.

The insulation was pushed all the to the eves and tightly packed (just pulled it back a bit today, can see a little day light at the very bottom, but I definitely have no ventilation on the eaves.

I have ordered some roof felt vents from Amazon, to hopefully  allow more air circulation.

As a temporarily fix, I read that someone had used some pipe lagging 3.5 cm diameter, so bought some, chopped it down into 10cm lengths and inserted at various staggered points (20 of) to enable some more airflow.

But still the humidity is high, I accept the pipe lagging, might simply be not giving the desired extra air flow.

My loft does not smell damp, there was a small amount of white dust on the wood, I tested it with a moisture meter, the reading was low at 10.2, the insulation did not look wet, none of the items in the loft had signs of mould damage. 

So my questions are

1) should I push the insulation back up to the eaves, due to no fitted eaves ventilation?

2) should the humidity of my loft /attic be similar to outside and an I worrying about nothing.

Leave a gap under the eaves rather than pushing the insulation right upto the edge. The heat loss will be minimal but it will allow airflow around the attic.
