Low pitch roof tiles explained
What are low pitch roof tiles?
Low pitch roof tiles refer to tiles that can be used on roofs with a roof pitch of less than 20 degrees.
Also referred to as flat or low slope roof tiles, low pitch roof tiles are designed to provide an efficient and long-lasting solution for shallow, gently sloping roofs, where conventional roof tiles and slates prove unsuitable.
Available in a range of materials, including concrete & clay. To work efficiently, they must be installed with extra care and details to provide a watertight seal to prevent water penetration.
This type of roofing solution is typically ideal for commercial or residential buildings with large open spaces or modern, minimalist designs.
What is the minimum pitch for roofs in the UK?
It used to be the case that 20 degrees was recommended as the minimum roof pitch, and flat roof coverings such as felt, asphalt, GRP and EPDM would be the choice at pitches below that. However, with advances in tile technology theLa Escandella planum low pitch roof tile can achieve pitches as low as 10 degrees.
Potential issues with low pitch roofs
The main issue with low pitch roofs is sufficiently draining the roof of rainwater. Use the wrong tile, and the potential for pooling is increased, hence the need to use a tile specifically designed for shallow pitches.
Advantages of low pitch roofs
There are a number of advantages with having a low pitch roof:
- Lower cost, due to smaller tiled area
- Easier to maintain
- More architectural freedom
- More aesthetically pleasing than a flat room, particularly for domestic extension projects
- Can solve some planning permission issues due to unobtrusive design
- Better suitability for solar panel installation
- Can be more storm & weather resistant due to interlocking design
