Tiles, slates & materials

Can I change my roof from tiles to slate?

Short answer: Potentially, but weight, pitch, batten gauge, headlap, detailing, planning appearance and structural capacity must all be checked before specifying the change.

What this means in practice

The product must suit the roof pitch, exposure, fixing zone, headlap, supporting structure and appearance of the building. Substituting a similar-looking tile or slate without checking the manufacturer’s fixing specification can create wind-uplift, weight and weathering problems.

What to check next

  • Do not assume lighter always means structurally simple
  • Check planning restrictions
  • Redesign details around the chosen product

When should you ask a roofer to inspect it?

Ask for the exact manufacturer and product in the quotation, not a generic description such as ‘grey tile’. A survey is important before changing covering type, reusing battens or mixing old and new materials on an exposed North East roof.

Safety first: do not climb onto a roof without suitable access, training and protection. Keep clear of loose coverings, unstable ceilings and water near electrical fittings.
