A roof extension is essentially expanding the roof of your house to create more usable space underneath. This could be for a loft conversion, adding a dormer window, or even extending your home outwards with a single-storey or multi-storey extension. People often consider roof extensions when they need more living space without moving house. Perhaps your family is growing, you need a home office, or you've always dreamed of a spacious loft room. A well-planned roof extension can transform your home and add real value. Century Roofing and Building can help you understand the options available for your property in areas across Kent, Surrey, and Sussex.

Planning permission can be a bit of a maze, but generally, yes, you will likely need planning permission for a significant roof extension, especially if it alters the roof's shape or height considerably. However, there are exceptions, particularly for smaller loft conversions with dormer windows that fall within permitted development rights. The best approach is always to check with your local council planning department in Kent, Surrey, or Sussex early in the process. We can also offer guidance based on our experience with local regulations in areas like Maidstone, Sevenoaks, and beyond. Century Roofing and Building can work alongside you and your architect to ensure your roof extension project adheres to all necessary regulations.

There are various types of roof extensions, and the best one for your home will depend on your property's style, existing roof structure, and your specific needs. Some common types we work with in Kent, Surrey, and Sussex include:

• Dormer Extensions: These are the most popular for loft conversions, creating a box-like structure that projects from the slope of the roof. They offer good headroom and light.
• Hip-to-Gable Extensions: Ideal for end-of-terrace or semi-detached houses, converting a sloping 'hipped' roof end into a vertical 'gable' end, maximising loft space.
• Mansard Extensions: These create a near-vertical back wall and a shallower sloping roof, often favoured in London boroughs and some areas of Kent for maximising space while sometimes appearing less prominent from street level.
• Roof Lifts: A more complex option, raising the entire roof to gain significant headroom throughout the loft space. This is usually for larger projects and requires careful planning.
  Century Roofing and Building can assess your home in areas like Ashford, Canterbury, or Tunbridge Wells and advise on the most suitable and cost-effective roof extension type for your project.

The timescale for a roof extension varies depending on the size and complexity of the project. A straightforward dormer loft conversion might take a few weeks, while a larger hip-to-gable or mansard extension could take longer. Factors influencing the timeline include weather conditions, the availability of materials, and any unforeseen issues that might arise during the build. At Century Roofing and Building, we always aim to complete projects efficiently while maintaining our high standards of workmanship. We’ll provide you with a realistic timeline upfront and keep you informed throughout the process, whether you're in Rochester, Gillingham, or further afield in our service area.

Cost is a key consideration. Roof extension costs are affected by several factors:

• Size and Type of Extension: Larger and more complex extensions will naturally cost more.
• Materials: The choice of roofing materials (tiles, slates, flat roofing systems), insulation, and internal finishes will impact the price.
• Location: Costs can vary slightly depending on your specific location in Kent, Surrey, or Sussex.
• Complexity of Existing Roof: Older or more complex roofs may require more preparation and structural work.
