What Slate To Use?
Posted 06 February 2015 - 11:20 AM
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?

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.

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.

Our soil vent pipes use these in line vents with a slate cut to fit around the little square grille:
