Benefits of natural Welsh slates

Durable

Welsh slate is one of the most durable roof coverings known to man. It has been quarried from Bethesda region for over 700 years.

Due to Welsh Slate being made up of natural minerals, they are highly resistant to corrosion. They also have a much higher resistance than other roof coverings which makes them less likely to cause damage during installation and maintenance.

Resistant

Welsh slates will withstand extremes in temperature without changing colour or becoming brittle for many years. These are some of the most heat resistant roofing materials available.

Low Maintenance

Welsh slate is easy to maintain and resists moss growth because they are a natural mineral product. They also have an extremely low porosity so it will not retain any water which means there’s little risk of mould or algae accumulating on them, even if left in place for many years.

Conspicuous and attractive

Both the Heather Blue and Blue/Grey colours are gorgeous and appealing to look at. These are some of the most beautiful roofing slates in the world. Most home and business owners opt to use these slate products because of this fascinating quality.

Cost-effective

Welsh slates require very little maintenance. When fitted in accordance with BS: 5534 Welsh slate will often outlast the building they cover.
