The challenge and solutions of low pitch tile projects

Planning on building a new extension for a client? Extensions are a great way to add value onto a property, as well as a little extra space.

Your client may opt for a traditional pitched as they not only look good, however they also offer multiple benefits such as good drainage while also requiring fewer materials to be used which also lowers building costs.

However, although a pitched roof extension may seem the most desirable option on a new extension project, they can have disadvantages.

This blog aims to explore when a pitched roof can cause an issue, particularly when it comes to finding the right tiles, and what solutions there are available.

Considerations and solutions for a pitched roof extension
Finding the right tile

The hardest part of building a pitched roof extension is finding the right tile that matches the main roof of a building, particularly as they will need to perform at a lower pitch than traditional roof tiles. This is due to the position of the first-floor windows.

Many of the traditional clay plain tiles can only be lay down to 35°-30. Newer, profiled interlocking clay tiles however can achieve the appearance of a traditional clay tile and can be lay as low as 12.5°, making them the ideal choice for any pitched roof extension project where the roof pitch is lower than property, and where the tiles need to match the appearance of the original clay roof tiles of the main building.

Water run off

A lower pitched roof can have direct implications on water run-off and for weather proofing as a lower pitch can cause a greater amount of water to collect and run off the slope.

Ventilation

As normal contour vents can often only be lay down to a pitch of 20°, this makes tile vents unsuitable for low pitch roofs extensions, however you can have a dry fix eaves vent system fitted to solve the issue of ventilation.

Building Regulations

Although since 2019, (with the exception of some designated areas  such as areas of conservation) you no longer need planning permission for a single story extension provided it is up to 6 metres for terraced and semi-detached property, and 8 metres for a detached property, the extension will still need to conform with the Building Regulations and British Standards.

With this in mind, all pitched roofs on extensions must comply with building regulation BS 5534.
