Not all natural slates are the same. Besides its beautiful appearance, Heavy 3 can last over a hundred years, making it a very cost-effective roofing material!

The best choice for Scottish roofs

Its extra thickness of 7-8 mm gives it the perfect strength to withstand Scottish weather while boosting the value of any property.

A poor quality roof needs constant repair and maintenance, but when good quality slate is used, not only the cost of re-roofing can be effectively discounted, but the repair and maintenance expenses during its lifetime are extremely low.

The use of Heavy 3 slates results in a low life cost.
