12 year old failing slate roof

[nid]

Hello all,
I am new around here, but would appreciate your advice.

I have a house which is 12 years old and has a slate roof. I have noticed that there are now nine or ten slipped or cracked slates on it and a surveyor friend of mine suggested that there could be something seriously wrong with the roof which requires it completely being relaid.

Is that really true? What could be wrong? Is there another way to fix it satisfactorily without tearing every slate off and starting over again?

Any slate roofer specialists please let me know!

Thank you very much

Sounds like the roof has been laid using economy spanish slate or brazilian slate which do have a tendency to break unexpectedly after being laid.

Just replace what is broken at the minute and expect the odd broken one here and there over time.

If this is the case then it will not be whole slates slipping out , just the bottom half sections.(a whole slate would probably be 20-24 inches long with two nailholes clearly visible on each side just above halfway up.

If it is whole slates coming out it could be a serious workmanship defect.

I agree with you regency,also if there are 9 or 10 broken slates and they are spanish you could end up breaking as much again replacing them 9 or 10.You could also expect to replace slates every now and then.Spanish slate are sh#te.

There are several reasons this is happening.
!/ poor quaiity slate
2/ damage caused after slates were laid (by other workers
3/ poor workmanship.
As already said Probably either spainish or South American.. but not 100%

Not all Spanish Slates are **** there are some very good slates from spain but most of the very best end up in Germany and the rest of Europe where good slate is demanded.

A photo zoomed as close as poss will be usefull for further comment...

I've recently had a roof replaced, felt and brand new slates. I've noticed that on a cold night, presumably when the temp drops to freezing or below, there's a lot of noise coming from up there somewhere. Sounds like rice pops, only a bit louder. Had a good look and none of them have moved and it only happens when it's really cold...anyone know if this is normal?

Thanks.
