Using the latest Flat Roofing technology that's pre-manufactured to your requirements, your new Flat Roof extension will be quick to build, hassle free and fully compliant with the latest Building Regulations.

This high-quality Flat Roof system is the most thermally efficient on the market with a U-Value of 0.12W/m²K and is available with either flat skylights, roof lanterns or no roof lights.

If you’re a fan of clean modern lines then a Flat Roof extension with flat skylights is the perfect choice for you, however if traditional grandeur is more your style, beautiful, pitched lanterns make a stunning statement.


The frameless flat skylights flood your room with natural light for an extension that is as cosy as it is beautiful.


The Ultraframe Flat Roof system is strong enough to span up to 5.6m unsupported above Patio sliding doors or bi-fold doors without expensive and often bulky additional support beams, bringing simplicity and style to your Flat Roof extension design.

Sit back and relax as all the structural and thermal calculations are taken care of within our specialist design software which engineers the roof to your exact postcode to make sure your new Flat Roof extension is equipped for the worst possible wind and snow loads in your location.



Combine our fast-to-fit Flat Roof system with Ultrasky Lanterns that allow Realistic Home Improvements to build your dream Orangery in less time than a traditional build. Pitched at the optimum angle of 25°, Ultrasky Lanterns allow the maximum amount of natural light to pour into your orangery, for a room that is bright, light, and airy.




The strength of the Ultrasky Lantern means that, not only do our lanterns look beautiful, the internal strength of the ridge means that we require 25% fewer bars. This technology ensures there are no cold spots and makes our lanterns the ideal choice for kitchens where high condensation levels need to be carefully controlled.




The Flat Roof system is available with two soffit widths, the Standard soffit with a 36mm overhang and the Extended soffit with a longer 240mm overhang.

You can choose from a wide variety of fascia options, available in white as standard or in any RAL colour of your choice, the Flat Roof system is also available without a fascia.
