Raising the roof: is yours suitable for a loft conversion?

As families grow and accumulate more possessions over the years, a once perfectly adequate-sized home can quickly become cramped. And when facing the expense and hassle of finding a new house and the prospect of uprooting your life for a little extra space, a conversion project is a no-brainer.

A loft conversion is one of the most popular types of property extension. Often completed in a matter of weeks and offering an attractive return on investment, it is no surprise that many people choose a loft conversion over moving house.

But as with any renovation project, there are some things to assess before getting started. First and foremost, it is crucial to ensure your roof can accommodate and support an extra room. A combination of criteria will determine whether your roof is suitable for a loft conversion, such as head height, roof pitch, roof structure and pre-existing obstacles.

So, what are the primary considerations for determining this suitability — and what can be done to achieve the extra space you desire?

Reaching new heights

Building regulations say that a roof must be at least 2.2 metres in height from the top of the ceiling joists to the bottom of the rafters to allow for practical headroom after insulation and internal ceilings. Without this space, your new room would be uncomfortable and impractical, negating the point of the loft conversion in the first place.

So, if your roof does not have the required height, is it game over? Not necessarily. There are things you can do to create more loft height. If your ceiling is only just shy of what is required, contractors may be able to shave off a few inches by fitting thinner modern insulation for more space and thermal efficiency.

If the difference required is more significant, raising the roof is a standard solution, which involves removing and redesigning some or all of the existing roof to add more headroom — a rear dormer extension would use this strategy, for example. However, you will need to get planning permission if this solution is required.

Achieving the perfect pitch

Roof pitch describes the slope of a roof. Getting the roof’s pitch correct is an integral part of property design, balancing aesthetic appeal with proper structural support and protection from the elements.

The pitch of your roof will depend on the style of property you own. For example, more traditional Victorian homes tend to have steeper roofs than ones built in the 20th century. Ideally, a roof should have a pitch of 30 degrees to accommodate an effective loft conversion.

The lower the pitch is, the lower the head height will be in the centre of the room. Inside your new loft conversion, the angle of the roof will impact the amount of usable floor space. So, you need to make sure you have enough headroom to walk around comfortably and that there will be enough functional space after installing staircase access to your new room.

Reinforcing structural support

Again, the structure of a roof varies depending on the style of the property. Traditional frames, most common in pre-1960s houses, are often suitable for conversion because they usually have rafters that run along the roof’s edges and provide ample space for development.

Alternatively, trussed roofs feature a ‘W’ shaped support system that takes up loft space and may make a conversion more complicated. Contractors can usually get around this issue by installing steel beams across the length of the floor to take the load off the roof.

Instead, you may opt to replace your roof to improve the structure and support the extra weight on your property’s foundations. In that case, you may also want to consider retiling your new roof as part of the conversion. Doing so can improve the way it looks from the road, improve insulation and prevent leaks, making your new loft room even more comfortable.

Addressing every obstacle

You might have a decent amount of attic space, but what is already up there? Whether you are embarking on a complete Mansard loft conversion to create maximum space or simply transforming your loft into a usable room with natural light using Velux windows, homeowners, designers and contractors must think about the practicality of the solution.

Many homes store water tanks or central heating systems in the loft — not exactly in keeping with the luxurious new room you are aiming to create. Plus, some houses will have a chimney stack that passes through the loft, further restricting the amount of usable space.

However, these things are often manageable with the appropriate planning and expertise. For example, you can maximise the space at your disposal by extending ceiling height and switching to a combi boiler with an extension vessel to supply hot water to the house through a more compact, sealed system.

  We are delighted with our new loft space! Our team leader, Mihai, was fantastic and kept us informed about progress throughout. Everyone who came to work on the space was friendly and communicative, and gave us advice about what might work best.
Together, the team created a superb space with two bedrooms and a bathroom which are all spacious and finished to a very high standard. Mihai took time to make sure that everything was finished as we wanted it to be and went the extra mile to ensure downstairs where they had broken through was finished and integrated with the existing decor.
The office team at The Loft Room were very helpful in keeping us up to date and checking in to make sure that we were happy with how everything was going. It made such a difference using a company who do loft conversions day in day out as it meant that everything ran smoothly, the project was managed for us and the build ran to the time scale presented to us from the start.
We would highly recommend The Loft Room to anyone who is thinking about creating a new space.

  We honestly couldn't recommend The Loft Room highly enough.

Our relationship with them actually started around three years ago when they first came out to quote for our loft conversion. We weren't ready to go ahead at the time, but when we finally decided to push the button this year, The Loft Room were still the company we wanted to use – and we're incredibly pleased that we did.

This was a significant project, creating an entirely new top floor with two bedrooms and two en-suites, all while we continued living in the house as a large family.

From the very beginning, The Loft Room had a genuinely friendly, family-company feel. Everyone we dealt with seemed to care about the project and about making sure we were happy, and they were very conscious throughout that this wasn't just a building site – it was still our family home.

A very special mention has to go to Jamie and Jared, who carried out the build. They were absolutely fantastic. They worked incredibly hard, were friendly, considerate and easy to have around, and we built a really good relationship with them over the course of the project.

Jamie's workmanship and experience were obvious from the start. He constantly kept us involved, asked questions rather than making assumptions and made sure we were happy with how things were progressing. Communication was excellent throughout.

With any building project of this size there are inevitably going to be challenges, changes or occasional delays. For us, the important thing was how these were dealt with. Jamie was always upfront, explained what was happening and kept us updated, so there were never any nasty surprises. If something needed sorting, it was sorted.

That made a huge difference, particularly as I work from home and we were living through the entire build as a family. Jamie and Gared were incredibly respectful of that and did everything they could to minimise the disruption.

Most importantly, we absolutely love what they've created. Turning what was previously unused loft space into two fantastic bedrooms and two en-suites has completely transformed the house. The quality of the workmanship is excellent and, looking at the finished result, we feel we've had really good value for what was a major investment in our home.

It probably says everything about our experience that after months of having Jamie and Jared here every day, we actually miss having them around! I work from home, so it's genuinely strange not having the daily chats anymore.

A really positive experience from the first conversation three years ago right through to completion. We'd happily recommend The Loft Room to anyone considering a loft conversion.

A huge thank you to the whole team – and particularly Jamie and Jared – for everything you've done for us.

  We have just had our loft completed by the loft room. They were really easy to work with, took care of all the paperwork. They were great at communicating all the stages and their response time was excellent. Adrian was our builder and he was fantastic. Super thorough, reliable, fast, tidy and often gave us suggestions when we were unsure. The whole project was finished in about 6weeks! We wouldn’t hesitate to recommend The Loft Room to anyone. Many thanks!

  We are so happy we decided to go ahead with The Loft Room. Everyone we met from our initial consultation with Paul to Lulian and his team and Helen and Melissa in the office have been great. We were especially impressed with the hard work of Lulian and his team even through the heatwave. They were friendly and professional and always ready to answer any questions we had. Thanks to Lulian for suggesting bigger Velux windows - they are amazing! All the trades involved were great - we will definitely use them again in the future. The work was completed on time and we are really happy with it. We would certainly recommend The Loft Room.

  We used the loft room for our loft extension and are very pleased with the results. We were lucky enough to have Adrian and Andre build the dormer, the whole experience was excellent from start to finish. The work was completed incredibly quickly, yet the quality remained consistently high throughout. Adrian brought great ideas to the project that genuinely improved the final design, and he kept everything neat and tidy every single day.
All the trades they works with — electrician, roofer, plumber and more — were equally reliable and skilled. There were no delays at any stage; each team arrived exactly when needed and kept the project moving smoothly.
The administration side Helen and Mellisa  was also superb, with clear updates and communication about progress and next steps. A very professional service all round.

  Off the recommendation of friends we engaged the Loftroom to refresh and extend our existing loft conversion, adding new insulation, skylights, a new shower room and additional bedroom.

We have never done major work to a property before so benefited greatly from loft room supporting us start to finish with planning, designs and all the various trades needed.

Our team lead Marius was excellent from start to finish. Him and his team were incredibly hard working, working quickly and to a very high standard. We were really impressed especially given they worked through multiple heat waves !!Their advise and guidance during the build was invaluable (see skylight in shower room!).

We wouldn’t hesitate to recommend Marius and the wider loft room team (who were very supportive every step of the way) to anyone looking to complete a loft conversion or improve an existing one.

  We recently completed a loft conversion with The Loft Room, adding two generous rooms, a bathroom and a proper landing, and we are delighted with the result. The new floor feels like a natural part of the house rather than an addition, and the quality of the finished space is excellent.

A special mention must go to Dave, who managed the project with patience, kindness and a genuine commitment to getting things right. Building work inevitably brings challenges and changes along the way, but Dave was consistently approachable, practical and willing to find solutions. He took real pride in the work and cared about the final outcome, which made a significant difference to us.

The whole team worked incredibly hard in our home, and we are very grateful for what they created. It was a major project for our family, and the additional space has genuinely transformed how we can use and enjoy the house. We would happily recommend The Loft Room and especially Dave.

  Getting a loft conversion done is a big decision. We were honestly quite nervous about it, especially given the investment involved and the number of horror stories you hear about building projects going wrong.

Thankfully, our experience with The Loft Room was the complete opposite.
From day one, the whole process was handled brilliantly. Everyone we dealt with, from the office team through to the various tradespeople who worked on our home, was professional, friendly and incredibly well organised. What impressed us most was that our loft was completed in just 9 weeks, and the quality of the workmanship never felt rushed.

A special mention has to go to Ashley C. He wasn't just the team leader overseeing the project. He was the lead carpenter and the driving force behind the entire build, coordinating all of the contractors, managing the day-to-day work, and making sure everything stayed on track. More than that, he felt like a genuine partner in the project. He understood that we had a budget to work within, took the time to listen, offered great ideas to maximise the space, and always made us feel completely comfortable and informed.

His communication was exceptional throughout. No question was ever too small, no concern was ever brushed aside, and he was always happy to walk us through things, sometimes more than once when we needed reassurance. Having someone like Ashley on site every day made what could have been a stressful experience feel surprisingly straightforward and enjoyable.

Every contractor who came into our home was polite, respectful and highly skilled. There wasn't a single issue throughout the build, and it was obvious that everyone took pride in their work.
In fact, by the end of the project, it was genuinely a little sad to see the team finish. Ashley had become such a reassuring and professional daily presence that we'll genuinely miss seeing him and the crew around.

We're now at the final decorating stage and can't wait to move into and enjoy our beautiful new space. We've been talking about our experience to anyone who'll listen, recommending The Loft Room to neighbours and friends, and proudly showing people the transformation.

If you're considering a loft conversion, we honestly couldn't recommend The Loft Room highly enough. They've completely exceeded our expectations in every way. 10/10 for quality, professionalism, communication and customer service. And if you're lucky enough to have Ashley C. leading your build, you'll be in extremely safe hands. He played a huge part in making our project such a success.

  We had our loft conversion completed by The Loftroom Teddington at the start of the year, and we're absolutely delighted with the finished result. The extra space has made such a difference to our home, and the quality of the work has been excellent.

A big thank you to Ash, who did a fantastic job and was always friendly, hardworking, and happy to answer any questions we had each morning (and throughout the day!). We'd also like to thank Paul, who was great from our very first interaction, as well as Melissa and Helen in the office, who kept everything running smoothly, and Rich, who regularly popped in during the build to check on progress.

As with any building project, there were a few small niggles, but these were dealt with quickly, professionally, and efficiently. It was reassuring to know that the team stood by their work and were committed to making sure everything was right.

Overall, we've had a really positive experience from start to finish and wouldn't hesitate to recommend The Loftroom Teddington to anyone considering a loft conversion.
Thank you to the whole team!
