SIGA Natural Slate – Classic Range
The lowest priced natural slates within the SIGA range. Classic slates often require more sorting and grading to produce a good roof. This makes them ideal for small patching jobs or low cost refurbishment work.

  • 30-year warranty
  • Most come with a T1 rating

Despite the lower price, all SIGA Classic slates meet the same strict testing and certification criteria as the commercial range.
