4 Reasons Heavy 3 has become the best roofing product

Slate has been used as a roofing material throughout Scotland since the middle ages, but when Scottish quarries closed between 1955 and the 1960s, Heavy 3 became the perfect choice for slate roofs.

Its close similarity to the traditional highland slate from Ballachulish (no longer produced) has made it the best choice for repair and replacement of traditional roofs in Scotland.
But why should you choose Heavy 3 slates for your roof?

1. Heavy 3 is a true heavy
Heavy 3 is produced at a thickness of 7-8 mm. This extra thickness gives it strength to combat dampness, high wind speeds and driving rains common throughout Scotland.
Performance is a criterion of greater importance when choosing a roofing material, and Heavy 3 will out-perform better than other roofing materials

2. No re-roofing of any Heavy 3 slate roof
A poor quality roof needs constant repair and maintenance, but when good quality slate is used, those expenses during its lifetime are extremely low.
Since CUPA PIZARRAS’ slate started to be used in Scotland more than 20 years ago, there have been no cases of Heavy 3 roofs being replaced or repaired.

3. Quarry’s reputation confirmed: 125 years of production
The slate characteristics depend on where it has been extracted. That is why it is imperative to validate the reputation from both the quarry and the company which produces it.
Heavy 3 slate is quarried from the CUPA PIZARRAS No 3 quarry in San Pedro de Trones (León) in northern Spain. This quarry has been in operation since 1892 and produces around 25,000 tons each year!

4. 100 years warranty
Choosing a CUPA PIZARRAS product means opting for peace of mind. The quality of their slates is guaranteed by meticulous control throughout the whole production process.
Actually, their resolute commitment to quality has led them to offer a 100 years warranty on Heavy 3 slates.

Thousands of architects, roofers and individuals around the world have already trusted them. What are you waiting for?
