Trussed Roof Loft

More than 1.000 lofts converted since 1989

You are here:

After the 1960s, most domestic roofs were built with a prefabricated trussed rafter construction. These can be more difficult to convert into living space than a purlin roof, meaning some loft conversion companies struggle. You need to select a specialist loft conversion company for the project – our expert team at Touchtone Lofts can easily convert your trussed rafter roof space into living space.

What is a trussed roof loft conversion?

A trussed roof loft conversion changes the structure of the roof, removing the supporting truss beams and replacing them with steel supports. You will need an expert structural engineer to complete the calculations and draw up plans, making sure the roof retains its structural integrity. An experienced construction team like ours will then be able to follow the plans, ensuring the build is a success. We have the knowledge you need – these are some of the hurdles we have overcome on previous projects:

  • Shallow foundations
  • Non supporting internal walls
  • Homes built with a concrete structure, a concrete block structure, or unusual types of block work
  • No lintels, or worn out supports over windows – this is a common oversight by many builders and can cause problems with windows or cracks in the roof

Trussed roof loft conversions can also be completed in timber frame homes – this can be a more difficult process as there is often only one layer of brick and support is limited. We have the expertise in house to create a suitable loft conversion solution for many different types of property.

How do I know if I have a trussed roof?

If you have a property built in or after the 1960s, it’s likely you have a trussed roof. You can tell by looking at the structure of the roof inside your loft. A purlin roof has horizontal beams supporting it from the inside. A trussed roof has wooden beams placed in triangular sections, forming a ‘W’ shape within the loft.

How much does a trussed roof loft conversion cost?
How long will it take to build?

It is very difficult to price trussed roof loft conversions without a survey, as they require more structural work. The amount of work needed will also affect the timescales. Please get in touch to claim your free design appointment (usually charged at £600) – we can advise you further once we’ve assessed your property in person.
