Description:
Slate & Halves are for use with the main slate (500 x 250 mm), on the verge or gable end of a pitched roof and along hips and valleys. Additionally, slate & halves are commonly used around roof windows.
Le Seca is a premium, first-grade Spanish natural slate that has become a popular choice for roofing projects across the UK. Ideal for loft conversions, extensions, and full re-roof applications, Le Seca provides a high-quality, long-lasting finish that can withstand even the most extreme weather conditions.
This slate features a smooth texture and a striking blue/black colour. Formed through tectonic compression, Le Seca is a non-carbonated slate with an exceptionally low pyrite content making it one of the cleanest slates available. The minimal presence of pyrite means the slate will not rust or discolour over time, preserving its clean, flawless appearance without compromising on performance or durability.
Roofing Outlet works directly with trusted Spanish slate producers to import Le Seca straight from the quarry, allowing us to offer this premium-grade slate at outstanding value for money.
Samples can be collected from our London depots, and we offer fast delivery across London and the Home Counties with crane-offload vehicles available.
