Suitable roof tiles for a low pitch roof

Roof pitches across the UK can vary from very low pitches of 12° and 15°, upto 70°, the most common type of roof pitch will be at an angle of 40-50°. When working with a low pitch, the choice of tile you make can have a huge impact on performance.

Advantages of a low pitched roof?

  • Less roof space to fill with air, aiding in the cooling of the property
  • Reduced installation costs, as there is less surface area of the roof to construct reducing both material and installation costs.

However, the lower the pitch, the more potential for water ponding to occur and leaks and issues with the roof. As wind-driven rain is blown across the ‘flatter’ surface, it can ingress into the roof and damage it. Finally, the lower pitch means it cannot drain as fast as a higher pitch roof. It is therefore important to know which roof tiles are suitable for a low pitched roof.
