Our full range of natural slate roofs are installed into the award winning Nu-Lok fixing system, our system has revolutionised the way natural roof slate is installed on roofs all over the world. Due to the unique fixing system, slate no longer needs to be double lapped or nailed.

Solar PV panels are traditionlly fixed on top of the roof, with Nu-Lok seamless solar inserts they actually become part of the roof and sit neatly in with the surrounding ceramic or natural slates, becoming a integrated part of the roof.

resistance and easy maintenance.


The Nu-lok roofing system incorporates specially designed link channels containing a high grade 316 steel clip for securing the leading tile edge, locked in place between galvanized steel battens.


The link channel eliminates the need for double-lapping of slates, as water passing through the gaps between slates is automatically routed onto the surface of the slate below.


With a Nu-lok roofing system you get a great-looking roof that is significantly lighter than traditional installations, quicker to install, and uses considerably less materials. And the cost savings from product, labour, and maintenance can be significant, making prestigious roofs more affordable.


The Nu-lok roofing system allows the use of ceramic slate or natural slate, and shingles can be replaced

in seconds courtesy of Nu-lok’s ‘clip in’ fixing system.




A revolution in roofing, the Nu-Lok System provides a prestigious slate roof that doesn’t cost the earth.


Easy to install, strong, and durable the patented Nu-Lok roofing system boasts impressive green credentials.
