Why get a roof lift loft conversion?

If your home is feeling a little cramped, a roof lift loft conversion could be a fantastic option for you. Whether your family is growing, or you want to install an entirely new room, your loft is a space that is bursting with potential. Paying a roof lift loft conversion cost can pay off in the long run too, as it can increase your property value by up to 20%.

This is particularly true if you choose to add an extra bedroom and bathroom. You may be considering moving to a larger home but love your current location too much. A loft conversion can add much needed extra living space.

Many people choose a loft conversion as a more affordable alternative to a traditional extension, but usually, there simply isn’t enough headspace. This is when a roof lift can transform and maximise the space of your loft. For more information on standard loft conversions, please see our handy loft conversion cost guide.

A roof lift sounds scary, but actually is a fairly common solution to a number of situations, including loft conversions where more space is needed, and if your old roof is badly damaged. You can even choose to change to a different style of roof.

With the option to choose an entirely new room, such as an office or children’s playroom, converting a loft is an exciting and practical project. This roof lift loft conversion cost guide looks further into roof conversion types, important consideration and up to date prices.

How much does a roof lift loft conversion cost?

Type of roof liftCost + VAT
(Range low - high)
Average cost
Roof lift loft conversion cost£20,000 - £60,000£40,000
Roof lift cost£1,000 - £45,000£23,000
Loft conversion cost£15,000 - £55,000£35,000
Bungalow roof lift cost£15,000 - £70,000£42,500

It is no surprise that adding a whole new floor to your home can be quite expensive. Despite this, the price you can expect to pay can be cheaper than an extension or a new larger home.

The average roof lift conversion cost is £40,000.

Common roof conversions

Not all roof conversions are the same. Each type has benefits and costs, so it’s worth looking further into these options to choose the right one for you:

  • Room in the roof: The least expensive roof conversion, the term ‘room in the roof’ simply covers the basics such as insulation, floor reinforcement and utilities. Prices for this type of conversion start from £15,000.
  • Hip to gable loft conversion: This conversion is installed on long sloping roofs (hipped roofs) and involves replacing this roof with a vertical wall. This greatly increases space in the loft.
  • Dormer loft conversion: Dormer windows are a fantastic feature for any home and involve adding a section to a normal roof that protrudes outwards. This type of conversion can be cheaper than a hip to gable conversion.
  • Mansard roof extension: Involves lifting the sides of a roof to create a new pitched roof. This option has a lot of potential for extra head space but is usually the most expensive conversion type.
  • Skylight conversion: One of the most reasonable options, a skylight conversion simply adds roof lights and stairs to your current loft. This does not increase the headroom of a loft.

Roof lift conversion costFactors affecting your roof lift conversion cost

It is unlikely two roof lifts would be the same due to the large variety of variables. Below are the most common factors that will impact your roof lift loft conversion cost:

  • Size of roof: Unsurprisingly, larger roofs will need more materials and longer labour times. This will mean higher costs.
  • Style of roof: As we discovered, each roof style is different and has a different price.
  • Shape of the loft space: Not every roof conversion is suitable for every home. In particular, unusually shaped lofts will be more expensive to lift.
  • New purpose of the loft: If you are simply looking for extra storage space, this will be much cheaper than a whole bedroom and bathroom. Loft conversion costs vary depending on the complexity of the project.
  • Roof height: Very low roofs may need to be lifted higher which will be more costly.
  • Added utilities: If you are using the space for storage, you are unlikely to need plumbing and gas facilities in your loft. If, however, you are choosing to add a bathroom or kitchen, the roof lift conversion cost will be much higher.
  • Finish: Whether you want to paint, tile or carpet your new space will push up the total price.
  • The condition of the current space: Lofts that are in poor condition may need extra reinforcements and insulation to make them habitable. This will incur extra costs.

It is very common for people living in a bungalow to consider expanding their home upwards. Usually, a bungalow will be quite large as all the rooms are on one floor.

The average bungalow roof lift cost is £42,500.

Roof lift costImportant considerations

Please read the following before beginning your project:

  • You will probably need planning permission.
  • Building regulations must be adhered to.
  • It may be necessary to work with an architect.
  • If your property is not detached, you may need a Party Wall Agreement.
  • You may wish to add dormer windows or roof lights to increase light in the loft.
  • Think about insulation and whether you need to add more.
  • Converting a loft to a kitchen or bathroom will be more expensive than other uses.

Can I install a roof lift loft conversion myself?

In a word, no. A roof lift loft conversion involves removing the old roof and lifting the new roof into place. The job requires scaffolding, a crane and other specialist tools not suitable for a DIY beginner. It is also very dangerous to work with electrics, gas and plumbing without the assistance of a professional.

You can consider saving money by taking on smaller jobs like decoration, flooring and plastering yourself. But, if any part of the job is not done correctly and safely it could cause injury, damage to your home, or even death.

Furthermore, a roof lift loft conversion involves specialist skills such as roofing, plumbing, gas engineering, electrical work and installing stairs. You will need to hire a professional for this project. To find a local, reputable, tradesperson in your area and get a personalised roof lift loft conversion quote use our free search feature.
