Here’s everything you need to know about how to plan a flat roof extension with a roof lantern installed.

Are flat roof extensions a good idea?

Flat roof extensions offer a contemporary look that complements existing architectural styles without imposing on your home’s character, thanks to a minimalist appearance. Flat roofs allow for versatile interior layouts and outdoor areas, such as rooftop gardens or beautiful roof lanterns installed for practical and aesthetical benefits.

However, it’s important to involve an expert roofing contractor throughout to consider factors like good flat roof drainage, insulation and maintenance needs when planning your flat roof extension.

What are the benefits of flat roof lanterns?

Roof lanterns are great additions to flat roof extensions, flooding interior spaces with natural sunlight. These glazed pitched roof panels have aesthetical appeal while achieving a brighter, welcoming indoor space.

If you choose a quality product, flat roof lanterns also offer excellent thermal performance while decreasing artificial lighting use during the day, helping with energy savings. They can also become a beautiful focal feature of your flat roof design, especially when placed over spots like kitchen extensions or seating areas, offering aerial views of blue skies and starry nights.

Does a roof lantern flat roof need planning permission?

In many cases, adding a roof lantern to a flat roof extension falls under permitted development rules. You won’t need planning permission as long as you meet the criteria outlined, such as defined height limits.

However, it’s best to check with your local planning authority to confirm whether your proposed flat roof extension with a roof lantern complies with permitted development regulations in your area.

How do you choose the design and material of your new flat roof?

When choosing the right design and material for your flat roof extension, consider factors such as durability, appearance and costs. Common materials for flat roofs include EPDM rubber and GRP fibreglass, each offering unique benefits in terms of longevity, installation and usage.

There are lots of different flat roof designs to consider when adding a roof lantern, and your roofer can advise on how to achieve a style to suit your home’s architecture. This includes colour options to complement existing brickwork and window frames.
