Tiled Pitched Roof Conservatory Conversions

A glazed or polycarbonate conservatory roof can make your conservatory feel too hot in the summer and too cold in the winter.

Glass and polycarbonate are poor insulators , and it’s quite common for homeowners to find the glare in both the winter and summer unbearable.

A Leka roof system will transform your glass or polycarbonate conservatory roof with excellent insulation set into a solid, tiled conservatory roof to create a more usable space year-round.  

How we use the LEKA Roof system

Is your conservatory always too hot or too cold? Are you looking for an affordable way to transform it back into a beautiful, useable space?

The Leka Warm roof  is a proprietary  system renowned for its superior performance and durability compared to conventional glass and polycarbonate roofing systems.  Its patented status ensures that our roofs are built to a consistently high standard.

Below, you’ll find an overview of the LEKA construction process. As a general guideline, we typically complete the equivalent of 5 square meters per day. Consequently, a conservatory measuring  15 square meters would require approximately 3 days for installation give or take a little extra time that’s alotted for more intricate or complex shapes.

Step 1

GRP Rafters

We remove and fully replace your conservatory roof with ‘Glass Reinforced Plastic’ ring beam and new GRP rafters. GRP offers superior characteristics, such as being lighter, stronger, and boasting greater longevity when compared to both aluminum and UPVC alternatives.

Step 2

Insulation and outer boards

Our insulation blocks have  an impressive U-value of 0.15, and for those seeking even greater thermal efficiency, we offer the option to upgrade to 0.12. Following this, we install exceptionally efficient outerboards, guaranteed to be 100% waterproof, topped with a breathable membrane.

Step 3

Tapco Slate tiles

Our roofs feature Tapco Slate, the ultimate lightweight tile that emulates the authentic look of slate. With a variety of colour options, you can seamlessly match or create striking contrasts with the unique ridge tiles. 

Tapco tiles undergo rigorous testing, meeting BBA, UKTA, and ETA standards, while also bearing UKCA and CE markings. These certifications cover essential aspects such as fire resistance, wind resistance, protection against driven snow and rain, as well as water absorption. Our roofs are built to last and are sturdy enough to support human weight.

Step 4


Your LEKA Warm roof will include brand-new fascias, gutters, and the option to select a hassle-free, low-maintenance ceiling. There’s also the option to elevate the  aesthetics and functionality of your new ‘room’ by incorporating skylights, lighting fixtures, or even opting for plaster and paint to create the perfect ambiance.


2Hot2Cold proudly offers a 10-year service guarantee for LEKA Warm roofs, along with a 10-year insurance-backed warranty, which is securely underwritten by The Consumer Protection Association.   Additionally, Tapco Slate tiles come with an impressive 40-year manufacturer’s warranty.

More 'Bespoke' and 'Character' Projects

A patented conservatory roof system such as LEKA (our preferred system) is perfect for those with straightforward conservatory shapes, but what if you are looking to upscale a more unusually shaped conservatory, bespoke orangery, flat roof extension or outbuilding?

So what would we deem as a Bespoke or Character project? Here’s a quick rundown of some of our more unusual jobs:

  • Insulating and cladding a rather large shed/Summer house so that it could be used as a kids’ den with a snooker table and tv
  • Converting ‘many’ lean to polycarbonate roofed conservatories into tiled Edwardian or Gable shaped roofs
  • Resurfacing damaged bedroom balcony floors for a lovely new fibreglass finish
  • Upscaling a wooden garden gazebo so that it had a tiled roof
  • Roofing rather grand (and large) orangeries, retaining  retaining the character of the deep wooden roof bars.
  • And we’ll regularly upscale conservatories that aren’t deemed as a ‘standard’ shape

It’s always interesting to learn how people will be using their new room.

We have converted a home hair salon, many Guest House dining rooms, Residential Home lounges …even a dentist! Gosh, that was fun trying to work around the dentist’s chair.

A bespoke or character project generally entails ‘space’ that needs to be revamped and good old-fashioned skilled expertise, which our team have in abundance.
