In the process of insulating my loft I have found that the area above my back bedroom and half my bathroom has no insulation at all. This is where the roof slopes down to the eaves and likewise the bathroom and back bedroom ceilings slope down in parallel to the sloping roof.
The space between the ceiling and house roof is about 6 inches so I want to put some insulation batts in this space. The problem is that there is a big purlin going right across the loft just before the roof starts to slope down and although I should be able to insert some batts over the purlin so they go between the joists, at the moment there is quite a bit of rubble in the space which I first need to remove. I've tried everything from a rake attached to an extension pole to a soup ladle attached to the pole to try to pull the rubble up to the purlin so that I can then get it out but the space I'm working in is just too cramped to make any headway.
The only way I can think of doing what I want is to do it from the outside by taking the first course or two of tiles off the edge of the roof and pulling the felt back so that I can then reach up with a sweeping brush and pull the rubble down. There wouldn't be too many tiles to come off as the eave length is only about 9 feet.
I know nothing about roofing so my question is: Is it possible to temporarily remove a course or two of tiles at the eaves without too much difficulty and then put them back and also how much would a roofer charge to do such a job - or how long would it take perhaps.
Any advice welcome. Thanks.
