Roof area and local used tiles

[Gymwear7]

Morning all.. we have an old devon farm house with large cement tiles. Expect to last another 10 ish years- locally someone knocking 5 bed house down to make way for new build. Been offered all tiles (Italian design 3 years old) for 500 quid.. but no scaffolding up. Would need to strip roof from inside and handball down..  i also have storage and manpower from friends... 

 

Being new to roofing.. is this worth the hassle ? 

Anyone done similar?  

 

Also is there an easy way to calculate roof area  ? Am using online calculators but unsure if I'm getting it right as they seem to assune gable ends ??? we have tiles on 4 sides (no gable ends). Floor plan 16m x 11m rectangle. 5.5m ground to top of wall plate..  wall plate to ridge approx 4m. 

 

Thanks in advance Jim

If you have large cement tiles why do you think they are only going to last another 10 years??

if your removing them I would want them for a lot less than £500, who else will want them?

Thanks @Russell Griffiths..  they've been on 25 years was an assumption on my part.. they're not broken but are looking a little tired.

 

I agree about £500 - what could I expect to pay for tiles new ? Hence the question about area.. 

 

Thanks for input.. Jim
