ROOFING &  
LOFT CONVERSION 
 
 
 

 Roofing WP Carpentry are able to undertake works utilising the latest methods of timber construction, but we take pride in carrying out traditional loose cut roofing. A cut and pitched roof allows for many shapes and details that would be impossible when using trussed rafters. These bespoke roofs not only match your specific design requirements but will often offer greater character to your property than a more generic solution.  

 Benefits of Loft conversions  MORE SPACE A professionally installed loft conversion can add a sizable amount of room to your property. Even the most modest sized loft will often provide enough space for a new bedroom and bathroom.  ADD VALUE According to Nationwide Building Society, loft conversions will on average add 21% to the value of your property – and sometimes far more. This makes the return on investment for a loft conversion better than any other form of home improvement.  

 
 
 
 
 
 

 Can my loft be converted? If you have 2.2m of headroom in your loft, then it is usually possible. Most houses will come with an allowance for permitted development, which means that you can go ahead with your conversion without planning permission.  

 Look for other conversions on your street An easy way to get an idea of whether your loft can be converted is to see whether any similar houses on your street have had loft conversions. If you do see examples, it's more likely to be a possibility.  

 Measure the head height The minimum height you need for a loft conversion is 2.2m. Take a tape measure and run it from the floor to the ceiling at the tallest part of the room. If it's 2.2m or more, your loft should be tall enough to convert. 

 Check what type of roof you have Depending on when it was built, your house will either have roof trusses or rafters. Look in your loft and you should be able to tell straight away what type of roof you have. Rafters run along the edge of the roof and will leave most of the triangular space below hollow. Trusses are supports that run through the cross-section of the loft.  

 Consider the floor below Many people neglect to factor in changes to the floor below the loft when planning a conversion. Consider where the staircase is likely to go and how much room it might take up. Even a well-designed space-saving staircase can use a lot of space, so make sure you have space you're happy to lose.  

 
Types of loft conversions 
There are four main types of loft conversion: roof light, dormer, hip-to-gable and mansard. 

Roof Light 

 
Roof light conversions are by far the cheapest and least disruptive option, as you won't have to make any changes to the shape or pitch of the roof. Simply add in skylight windows, lay down a proper floor, and add a staircase to make the room habitable.  
 
However, you'll need to have enough roof space already without having an extension for this type of conversion. 

Dormer 

 
A dormer loft conversion is an extension that protrudes from the slope of the roof. Dormers, in particular flat-roof dormers, are the most popular type of 
conversion.  
 
They are suitable for pretty much any house with a sloping roof. 
 

Hip to Gable 

 
Hip-to-gable conversions work by extending the sloping 'hip' roof at the side of your property outwards to create a vertical 'gable' wall, creating more internal loft space.  
 
This type of conversion will only work on detached or semi-detached houses, as it requires a free sloping side roof. 

Mansard 

 
Mansard extensions run along the whole length of your house's roof and will alter the angle of the roof slope, making it almost vertical. 
 
Mansard conversions are suitable for most property types, including 
terraced, semi-detached and detached houses. 
 
 
 

 Will I need planning permissions? Many loft conversions are covered by permitted development rights and won't need planning permission.
