I have just installed some 200mm insulation (over the thinner insulation already there) in the eves of the loft as the centre is boarded over for storage. We hope to have the old slate tiles renewed next year as we get a lot of dust and mortar falling off them they are so old. In the meantime I was wondering if sheets of bubblewrap could be placed over the new insulation to stop dust falling onto it as well as any possible water leaks that may fall onto it and spoil it. Also, could the rest of the loft have it attached with drawing pins temporary to the wooden roof frame to stop further dust falling in as well as insulating the loft further until the tiles are replaced ? My brother in law did the same with his roof except he used thin polystyrene sheets which has made a huge difference to his fuel bills.

Use a 'breathable roof membrane' stapled to the underside of the rafters. Look on ebay for the cheapest suppliers.
How will you lay the bubble wrap then?

By placing it loose over the top of the insulation. It's very light.
You'll have to walk on the joists to do that though won't you?

No, it's not too big of a space and I can use a pole to guide it over 
i suppose anything between the tiles and the loft floor is good for trapping heat. I have some cardboard sheets i could staple but probably not ideal. Just something until I have the tiles replaced because they may damage breathable sheets.

Your bubble wrap will have no ramifications so feel free.
BTW the breathable membrane I mentioned would have only been temporary anyway, when your roof is replaced a new membrane will go on top of the rafters anyway.
