Relaying roof - advice needed

[b21playa]

Hi all

I am thinking of getting the roof of our 3-bed semi stripped and relayed due to their being no felt/membrane. also the old tiles were motar'd on which is now crumbling and falling onto the insulation which is very dusty so has been binned.

I want to re-use the tiles and there is no leaks and I like to look of the 6x4 rosemary tiles we have.

What sort of time frame could such a job take, taking into account there will be scaffolding all the way around (will get facias and guttering redone at the smae time while its up).

I know the weather will play a big part, but a rought time will enable me to calculate pricing. If anyone has had a similar job done, and could let me know what they paid, that would be great

Thanks

To be honest re-using the tiles that havnt crumbled is a waste of time, replace the lot.
The tiles sound like they have blown, so it will only be a mater of time till the ones you want to save will do the same!
Replace with new plain tiles, the costs vary from clay being the best looking to concrete ones which will do the same job.
Using small tiles will cost you maybe 3 times more due to the amount of tiles you have to use and the time it takes to lay them, if you use larger concret tiles it will be cheaper.
Hope this helps

the o.p. did not mention the condition of the tiles merely that the torching is shot. as are most roofs that have used the old torching method.

there is a risk the tiles may be delaminating but this is not always true for all tiles and the o.p. hasn't mentioned delaminating.

If the tiles are near 50 years old, then you should replace them. Or you may well be re-roofing again in a few years time.

If the tiles are changed to large concrete, would the 3x2 rafters cope?

You may be looking at £2.5-3k for reusing tiles and add £1.5-2k for new plain tiles, less for interlocking concrete.

And allow for any chimney work and lead, and gutters and fascias

im only guessing here but i would say a 3 bed semi with no felt membrane would be build in 1950 or before and as woody says if there over 50yr old tiles they have probably have had there day.
As for taking the weight plain tiles (rosemary clay ) are actually heavier per m2 than say marley modern(large concrete) tiles.

Correct!

Actual age has little to do with anything, 100 year old peg tiles for example are often as sound as the day they went on..

tiles are in good condition, no delamination

No, age has a lot to do with it, as does the actual batch, manufacture and source of the tiles.

If all similar roofs in the area are fine and few have been replaced, then maybe they are OK. But if there are replacements roofs and roofs with some replacement tiles, then its safe to assume that they are at the end of their life.

They may look OK from the ground, but when they all start to break when removed or refixed, then it gives it away.

Yes there are Tudor tiles which are still going strong, but many of the pre and post war properties in Birmingham have clay tiles are at the end of their lives - they are nothing special.

Also,
if you say the tiles have been bedded on, dependant on how strong the mix is in first place the tiles won't come off whole anyway, usually if bedded strong, they will all break in the process of removal.

BEDDING IS RUBBISH, ITS CRUMBLING
