Loft Insulation at eaves

[au8830]

I have a early 1970s bungalow, with typical low pitch roof. The tiles are interlocking concrete tile (look like Marley Wessex) and there is black "felt" underneath. The timber soffits and fascias do not have any visible vents. Under the last row of tiles there is some kind of plastic moulding that I suspect is a retro-fit. I didn't want to poke around too much because the tiles aren't in the best condition. Edge of the roof is finished with dry verge with traditional cemented tiles on the ridge. Wall cavities have been filled with blown-in fibreglass.

Above the ceilings there is the (original?) thin layer pink insulation, and this has subsequently been topped up by the previous owner.

Based on the construction of my roof, what should I do with the insulation, with respect to the eaves? I have pushed it into the eaves, leaving a gap of an inch or so between the top of the insulation and the underside of the felt. Obviously, due to the low pitch, this leaves quite a significant strip of uninsulated ceiling which is confirmed by IR thermometer readings.

Is there any harm in pushing insulation further into the eaves? At the moment I have no moisture problems in the attic.

It might just be me but I don't quite follow why you have a strip of ceiling you can't insulate?

You should ensure you have adequate cross ventilation, though sounds like you might have something like this already: https://www.google.co.uk/search?q=e...=R8MrVbuxAsn1aoewgNAO&ved=0CAcQ_AUoAg&dpr=0.9

I just re-read what I wrote, not clear.

It's not completely uninsulated; the original pink insulation runs right to the edges of the ceiling, up to the wall plates, but it's only about an inch thick. There isn't enough height to get the full depth of insulation into the gap between the ceiling and the underside of the felt (if allowing a gap), so all of the top-up insulation stops short.

As for the eaves ventilation, I'm not sure. I had a better look this week, and it appears that the plastic inserts are just eaves protectors. The roof space doesn't appear to have any moisture problems. I take it that the design of this roof is to not have air infiltration/cross-ventilation, but instead to allow some amount of moisture to permeate out through the felt?
