SIGA 32s Random Width

SIGA 32s Random Width is supplied in blank, random-widths and diminishing length courses to suit your project, reducing labour, and providing an authentic roof finish. The SIGA 32s Random Width is approved by Snowdonia national park due to its similarity to the indigenous Welsh Ffestiniog slate in performance and aesthetics. Unlike second hand materials the SIGA 32s Random Width is supported by the SIGA warranty for total peace of mind.

Traditional Scottish slating is not recommended on roof pitches less than 25 degrees, but they can be laid up to 90 degrees. However, it should be remembered that at lower pitches side lap becomes increasingly critical and that sufficiently wide reclaimed slates may not be available. It may be preferable to consider a new SIGA 32s Random Width slate to replicate original Scottish slate where side lap is a concern.
