Roof tiles & mortar

[Paul Miller]

Not a paving related question, but I’m sure someone should be able to help.

My house is a 1952 semi, and the roof tiles (small clay ones) are bedded in mortar. There is no membrane as such between the underside of the tiles and loft, and I get a continuous rain of mortar dust coating everything in the loft. I’m surprised there is any mortar left if this has been going on for nearly 60 years !!

I intend insulating and panelling in the roof area of the loft and was wondering if I could spray the underside of the roof with anything to stabilise the mortar. I was thinking of spraying it a PVA solution. Would this work ? Or is there anything else that would be better ?

Cheers

paul the tiles must be on battens
if its not leaking leave well alone
dont spray anything as this will seal the timbers and potentially cause them to rot
when you do get leaks , it costs roughly £4.5 k to strip ,felt batten and put new tiles on
if it aint broke dont fix it mate

Yes, they are are battens. But they are also mortared in. It's the rain of mortar dust I'm want to stop. I'll post a picture later tonight when I get home.

i have seen them mate,many times
maybe tack some breathable felt to the underside to stop the dust
you will need to consider felt and batten at some point

before i stripped my roof i was in the same postion. i used some ttram [wovern membrane] i had hanging around. this stopped the stuff falling on my junk. think i left it on when i felt and batterned it. the stuff is called pargeing i think, used for a bit of draft proofing i think.

[lutonlagerlout]

draughts are good for roofs
yeah parging sounds right dylan,sen it in chimneys too
my roof is hand made clay tiles on feather edge battens
going to be a right pain to strip and refelt,

if theres no felt on them why bother. i only did mine because i was converting my loft. got fancy scolloped hand made staffordshire blues on ours.

[digerjones]

i know what you mean, i came back and the sign writer had done it like this and i thought it was a bit odd but hey ho. funny because i only had it sign wrote so it looked better than a un wrote pickup, as you have nowt to hide with your own name on it and so you did'nt look like a pikey and i supose it did the opposite, i look like a tallented one ha ha.

[digerjones]

giles i think you wont be far off with that price, looks a good machine. its mad how they hold the money, you proberly paid something similar 11 years ago
