Old roof - add felt, or something internally?

[JP_]

1930s house. Roof all OK. Tiles in good nick. But there is no felt and it gets really dusty in the loft, so much so that we don't store much up there.

Obviously I could get a roofer to remove all tiles, remove battens, felt and replace (and hope no tiles get damaged in the process). But guessing that would cost a lot.

Would it be sensible to do something from the inside, DIY? If so, what? Obviously dust will still get in, but at least it'll accumulate at the bottom. Maybe just staple some of that foil insulation to the rafters? Although not bothered about insulation as such, as loads in the loft already. Could a felt be fitted to the underside? Or would something terrible happen?

Yes just get a cheap breathable membrane something white preferably.

why white? Any suggestions for good cheap brands / places to order? Looking online, but cannot workout what is cheap is they're all different sizes!

this maybe?

metre wide rolls may be easier to use inside the loft. i'd avoid the lite versions ??

that's a bit cheaper - I could probably get most done with one roll, maybe 2 rolls.

The darker the felt the darker the loft.

ah, that simple. PRetty dark anyway, although I guess a nice light felt will brighten it up a bit!
