Slates as old as the earth itself

Slate has been formed by a process which is almost as old as the earth itself. it began when surface rocks were worn away by wind and water and deposited on the floor of the ocean that covered this area of Wales.

The deposits, through the Ordovician period, some 500 million years ago, became buried beneath the earth and were subjected to intense pressure and heat, forming them into sedimentary rocks.

Later movements in the earth's crust exerted immense forces upon these rocks, forcing them up into colossal strata's on the mountain sides as the waters receded.

For centuries welsh slate has been used for the roofing, cladding and flooring of buildings world-wide, from cottages to palaces.

Due to slates natural qualities, and characteristics it is ideally suited for prestigious projects.

Its uses are not only limited to roofing, but can be used for steps, pool surround, kitchen tops windowsill's etc.

Its uses are only limited by one's imagination. roof slates are produced from a natural material, each individual hand made roof slate will have its own unique visual characteristics.

Wastage of Roof Slates:

Normal wastage in Transport of any slates New or Reclaimed is approximately 2% to 3%.

Normal wastage to get the Slates up to Roof Level is approximately 2%.

Sorting and Grading:

Before the Roofer / Purchaser receives the slates they will have been sorted and graded:

Reclaimed Slates are bought from demolition sites / refurbishment projects etc. Once purchased they are sorted and graded either on site or back at our premises.

Sorted Slates: Broken and unusable slates discarded, and then all usable slates are crated / palletised and counted ready for sale and transport.

Once the sorting process has been completed we then move on to the grading of the slates:

Grading of Slates: i.e. we ensure that each job / batch of slates are kept together so that the end user receives the slates from the same job / batch. This is so that the slates in each crate / pallet are as similar to each other as possible.

This sorting and grading process ensures that the slates supplied to the roofer are as suitable as possible for his project.


The Roofers: sorting and grading is a completely different process which involves sorting thickness, coursing, re-holing and dressing ready for fixing to the roof.

Wastage: when fixing the slates depends on many factors i.e. the complexity of the project, ( valley cuts, skylights etc) and the experience of the Roofer.

Taking all these factors into consideration, we recommend you allow approximately an extra 10% when ordering your slate.

The waste created by the roofer's sorting and grading process should be calculated into the quantity of slates ordered. This can vary greatly due to the type and complexity of the roofing project, and can be especially high and difficult to predict when using Random Sized Slates.


Calculating Wastage of Random Sized Slates:

It is very difficult to work out your expected Coverage and Wastage from just looking at the slates in the crates, because of the nature of the slates all being random sized.

This is where the experience of the Roofer and/or Purchaser is essential.

When we supply random sized slates, we can calculate an approximate m² coverage per crate, from the variation in the sizes and number of slates.

You should also take into account that when the roofer's dressing and coursing of the slates in preparation for fixing is complete, the purchased m² may be insufficient to cover the area required. Therefore, additional slates may need to be purchased.

You may have to make a random sized slate smaller, which can still be used on the roof, but will reduce how much your purchased m² will cover, and increase your wastage %.

Therefore the true calculation of wastage is only possible once the project is complete.
