Hi again

I'll soon be ready to slate a new build, last time we did one we used Brazilian green slates and hung using hooks...this was over two years ago and I got to say the roof still looks great.

At the time this slate was good value but is there a better alternative out there? If not what do others like to use?

Cheers

Merv

Are you required to use natural slate or can you consider a composite tile with the appearance of slate (such as those used by Jeremy on his build - Ikoslate if memory serves). Could save quite a bit of money?

I liked the colour of the Brazilian slate samples I've seen, but each supplier I spoke to said that they didn't like selling them as they are not as durable compared to slate from other regions, have a much shorter guarantee and must be hung with the hooks you describe to maintain the guarantee. Personally, I don't like the apearance of a roof done with the hooks and they are an added expense to be factored into overall costs, but each to their own.

At one stage I had over a dozen slate samples under scrutiny in every type of light possible and rejected an offer of another supplier entering the mix as I was suffering from too much choice!

I wanted to avoid dark slate and was really after the closest thing to a Bangor blue with a rugged texture that I could find. The two choices I narrowed down to were the Classic Blue Chinese slate from LBS (in NI) and the Samaca Q49 7mm from Capco Roofing Products. In the end I went for the Samaca because it was available in 24x12" and had a nicer texture IMO, but this did work out a few hundred pounds more expensive.

The main thing to look for when buying slate is that they are A1, S1 and T1 certified so that they are durable, colour fast and will not rust due to excessive mineral content.

Our roofers had used Samaca slates on a previous job and said they had problems with cupping and breakages, but have found our batch very consistent.

I can take a few pictures when I'm on site today and post them later.

The only thing I would say about man made alternatives is that generally, they will not look better with age but a natural stone product can and probably will develop a pleasing patina over time.

It's good you have a choice, because I'm building within a National Park I'm forced by a planning requirement to use a single local supplier Burlington slate.

A developer I know was under similar pressure from the planners, who quickly backed down when confronted with a near-identical Spanish slate sample and threats of breach of European competition laws.

Similarly I was told the choice was black cambrian slate or clay tiles. I used Ikoslate, made from recycled plastic, and they fool everyone who sees them (including the conservation bods!). 1/3rd the weight of slate, near zero wastage (a slate cut in half with a saw con have both halves used) and they are well-proven not to fade over at least 20 years (they are, sadly, a US product that has been in use there for decades).

An interesting thread - we are not quite in a position as yet, to make such decsions but on our radar, we have slates from Greys Art Stone - a reproduction slate with the appearance of natural slate - Are there any experiences or thoughts amongst the collective regarding these ?
