Questions & Answers


what is their thickness


approx 4mm


Hi how thick are they




Could I please ask the thickness of the tiles , and have they got pre drilled nail holes. Also do you do the same type of tile as 1.5 width.


Yes they are pre holed and no only a double


recommended method of fixing


Copper nails 31mm or 38mm depending on the job


How many slates do i need for 50sq/m Thanks


You use 14 slates per m² so approx 700 for this area.


How many are needed per square meter ?


These are slate and a half so you would not use these over the whole roof just to start every other course running up the roof. If you email your requirements to sales@roofingsuperstore.co.uk we can look into doing a quote for you.
