Another roofing question

[Sabina]

Got fed up of clearing up the muck dropping through our ceilings where there is no insolation.

Has anybody found a product to fill the gaps between the boards supporting the pantiles?

Have used newspaper and exterior filler on a small area but this will take forever on the outhouse roof.

Any advice appreciated

Try the cans of polyutherane mousse, available in most DIY places. Be very careful it does expand a lot but it did the job on gaps around our windows and between floorboards.
