What is a Timber Upstand & How Can I Build One?

If you are adding a skylight to a flat roof, you must decide on whether to construct your own upstand or purchase one from your rooflight supplier.

The job of an upstand (sometimes referred to as a Kerb) is to lift the glass element of your rooflight off of the roof’s surface, and is required by building regulations for safety and weathering reasons. The upstand must be at least 150mm in height and should a minimum pitch of at least 3 degrees.

Should I make my Own Upstand?

Cost is generally the main reason people choose to make their own. A simple upstand can be constructed from excess timber on site minimising waste or using standard timbers found at any local wood supplier. Creating your own upstand also allows your to weather your roof without the rooflight lid being on site protecting it from any potential damage.

If you would like to build your own upstand and require more information you can visit our technical downloads page for specific measurements.

Insulated Upstand Detail

A more advanced detail is the equivalent of creating a mini stud wall. The purpose of this is being able to insulate the inner cavity which gives greater thermal performance and sound insulation.
