Slate roof - losing tiles - expected?
Discussion

What's the correct way to replace and fix individual slates without removing the ones above all the way to the ridge?? I wonder if the 8 replaced so far have been done properly.
There isn't any method that is as good as the original fixing, cooper wire was used years ago. I'd imagine these have been stuck back in with something along the lines of liquid nails.If the bottom two thirds are coming out it could be that they are cracking along the line of the nails, as mentioned nailed too tightly and if not graded by thickness the don't sit flat, looks like a combination of poor quality slates and possibly poor fitting, although its impossible to say anything 100% without a proper look.
Pretty sure slates have to be a minimum quality for NHBC standards so it will interesting to see if they meet the standard. Due to cost its highly unlikely to be Welsh slate, and as mentioned already, more than likely Chinese.

Roofer, whats your opinion on spanish slate? I'm looking at having a garage roof done in slate, can't afford welsh etc..
Get a SIGA 39 , that'll be fine for a garage. Spanish can have a lot of pyorite in it, if you see a slate roof with a lot of rust streaks on it, its a cheap slate.SIG Group should carry stock near to you.

We moved into a new build Taylor Wimpey house in May 2013.
Since then, we have had 8 different roof tiles come off and be replaced by the developer.
One time, a tile on the rear of the house flew over to the front an dhit my car on the way down (it was an old Mondeo at the time) which has made us nervous of parking in our own drive when the weather is like it has been the past few days.
There are 2 showhomes, and 6 other houses in an arc on the front of the development.
Every house is missing at least 2/3 tiles at the moment and we have all lost some over the weekend.
When the wind gets up, the noise is incredible, it sounds like the whole roof is flapping about.
Does this sound normal?
The slate roofs do look nice, the houses further into the estate have flat tiles on them and do not appear to suffer from any wind damage at all. Are we sacrificing aesthetics for resilience?
We are thinking about approaching TW to discuss as it is affecting all of us in the front but I wanted to get a feel for whether we are being unrealistic and given the recent storms, is this kind of thing expected to a certain extent.
We had exactly this situation with a slate tiled house with Wimpey. We kept getting slate failures, one narrowly missed our car and others ended up deeply embedded in the back garden.Since then, we have had 8 different roof tiles come off and be replaced by the developer.

Was like they weren't used to working with them and trampled all over the roof when fitting them breaking loads, when they came to repair they would strap and glue the replacement but in doing so trample over a load more and then we would see additional failures.
After a lot of complaining they ended up scaffolding our house and getting somebody with more knowledge in to carefully come and check the roof and replace any that they felt were substandard. Probably was about 20 further tiles. After that the failure rate dropped significantly. They also wrote to confirm they would provide a no quibble guarantee on the roof for 5 years and gave us a stack of spares for the garden.
In all honesty in drove us both absolutely bonkers, we never expected repeated issues with a roof on a new house and that in addition to shocking standards of construction which forced us to refit all 3 bathrooms to cure shower leaks / blooming on to surrounding plasterboard which Wimpey had about 3-4 goes in fixing and couldn't. We ended up selling and moving on, as did many of the neighbours.

Hiya mate - could you tell me the name of the development? Would be good to keep in my back pocket in case things turn sour.Was like they weren't used to working with them and trampled all over the roof when fitting them breaking loads, when they came to repair they would strap and glue the replacement but in doing so trample over a load more and then we would see additional failures.

It may be worth contacting someone like http://www.rcimag.co.uk/pitchedroofing.asp They have quite a few experts that write articles for them and may be willing to do a report/carry out testing for you. Perhaps best if you can join with your neighbours for a 'class action' type thing. Or maybe 'roofer' knows of an alternative resource of knowledge? Or maybe http://www.welshslate.com/downloads/?area=roofing
A good slate roof is an excellent choice for looks, durability, performance, low weight... normally

I am hoping the developer will see sense here as we all live on the front arc of the development, right next to both the show homes and sales office.
The site still has 3 years or so to go (at least) and because of good visibility, they will not be moving the showhomes further in as some sites do.
This means the first thing people will se as they drive in is our houses.
If we don't get a satisfactory resolution, i'm sure a few well placed notices could be in order
I think a new house losing its roof is shocking. Personally I'd be wary of them just trying to bodge it to get past warranty period and leaving you with a big problem.The site still has 3 years or so to go (at least) and because of good visibility, they will not be moving the showhomes further in as some sites do.

SIG Group should carry stock near to you.
Probably only of interest to roofer , if you come across any second hand welsh slates with a rusty tinge to them they will be salvage from a steel industry town , all the ones from consett area in Durham are quite red - brown . SIG Group should carry stock near to you.

Update after roof inspection:
The following is the content of the roof inspection report:
While on site a full inspection was carried out to the property where access was gained to the roof via steel ladders for safe working platforms all in accordance with current health and safety regulations.
1)The roof to the property is a Spanish slated roof and in keeping with other properties in the area, all rainwater goods are of black Plastic Rhone’s surrounding the property and are in good condition, the roof slates are a uniform 16” x 10” pitched style set in several part sections and would benefit from an overhaul of only 2 repairs required, the roof has a breathable under slating felt in place which fully overhangs at eaves level into new Rhone’s, all Spanish roof slates are double nailed and most parts are well slated tight and secure.
2)All continuous dry verge units to the property requires more fixings in place, while on site I was able to move this dry verge unit quiet easily where Mr XXXXXX explained that this noise was a familiar to the sound he has been experiencing late at night. (When the outside temp drops below zero, we often get creaking noises occuring, very disconcerting and regular).
3)While on site a full inspection was also carried out to all zinc ridge units which were found to be in good condition, these were found to have the correct amount of heavy duty ridge brackets installed ( four per length) however the “tapper course” or last course of Spanish roof slates are only single head nailed, these were turned under the zinc ridge and very easy to lift up slightly, this was not as the rest of the roof slates were found to be and require double nailing and clipping to prevent further damage occurring This would explain the "chattering teeth" noise we get when the wind gets up to gale force
4)There are two GRP valley gutters to the property and both look to be in good condition with no problems or damaged areas visible.
Overall the roof to the property will require all zinc ridge units removed to allow for new tapper courses of roof slates to be renewed with a double nailing and clipping technique applied, all verge units will require more fixings to secure to prevent noise levels internally.
I will send this report onto Taylor Wimpey and see what they say. We had 2 houses inspected and these issues were evident on both so safe to assume they will be affecting all 6 properties in the street.
