There are a number of factors to consider when a slate roof is being designed. These include the site’s exposure rating, the type of slate being used, size of the slate, and the pitch of the roof.
Guidance on these issues can be found in British Standards BS 5534:2014, the Code of Practice for Slating and Tiling.
BS 5534 recommends a minimum pitch of 20° – however, SSQ has developed a slate roofing system that allows the roof’s pitch to be as low as 17.5°, and in some instances, a roof as low as 15° can be designed in areas considered to be ‘unexposed.’
This is because, unlike most other roofing materials, our Low-pitch Slate Roofing System provides greater design flexibility. This is achieved by using a combination of special-width slates, hook-fixing techniques and 35 years of knowledge and experience in the slate roofing industry.
The SSQ Low-pitch Slate Roofing System has been used on a number of excellent projects that showcase its success. Get in touch with our Technical Manager Richard Cook here to find out more.
