12.5Ā° minimum pitch applies to Mendip 12.5 only. Standard Mendip has a minimum pitch of 15Ā° available in smooth finish tiles; granular finish tiles have a higher minimum pitch requirement
Experiencing the vast variety of textures and colours that our roof tiles provide up close, can guide you in the decision making process when selecting roof coverings. Our efficient sample service can help you in this process.
NB: For all Mendip 12.5 sample requests, please note that you will receive a standard Mendip tile for colour and profile reference. Modifications to the Mendip 12.5 are hidden by the recommended headlap although both versions have the same appearance on the roof.
Standard Mendip interlocking tiles can now perform at extended rafter lengths:
15Ā° - 17.5Ā° pitch with a rafter length up to 10m will require a 100mm headlap
17.5Ā° pitch and above with a rafter length up to 10m will require a 75mm headlap
Mendip 12.5 can perform at pitches of 12.5Ā°- 44Ā° with a rafter length up to 6m, which requires a 100mm headlap.
To ensure that your roof is compliant to the new standard, our fixing specification service is available.
