Flat Roof Design – A Wealth of Options

Flat Roof Design – A Wealth of Options

Flat roof design begins with the planning.

In times past, flat roofs had limited options but now anyone considering a flat roof for their project has a wealth of options and different styles from which to choose.

Whether it is an extension to a domestic dwelling, a community center, improvements to a church or an environmentally friendly building designed to blend in with the countryside, there is a flat roof option to suit.

However, getting a flat roof right comes down to design and planning.

Flat Roof Design – A Wealth of Options

Before you can begin to design a flat roof it is necessary to know the range of options and different styles available.

At Topseal, we are the UK’s leading flat roofing provider with our products installed across millions of square metres of UK roofs. That means our products have been used in every conceivable type of project – we know what flat roofs can be used for.

Rather than listing every type of roof, it is better to show you a few examples.

Have a look at case studies to get inspiration, clicking on them brings up a little more information about the project. One great example is The Spires where flat roofing was used to repair the domes on an old church – hardly a typical flat roof usage.

Flat Roof Design Examples

At Beech Lodge, flat roofing was used in a renovation project to create a simulated lead look to blend in with the rest of the property, including the bay windows. This gives the property a like-for-like lead look while avoiding toxic water runoff and criminal damage, both of which are associated with a standard lead roof.

A Topseal flat roof was installed on a set of new build flats at Captains View. Alongside giving the property manager a guarantee that the flat would remain watertight for 30 years the flat roof has been designed to make a statement and add to the design of the building.

At Eagle House, an extra durable Topseal flat roof system was used on a 1,200 square metre commercial roof. As a Topseal GRP system was installed the large roof doesn’t feature any joins which are often the weakest part of a standard roof system.


A smaller project was Whyncrest Lab where Topseal roofing was used to create a flat roof that doubles as a balcony with anti-slip finish. This shows the domestic potential for Topseal systems and our waterproof system is just as effective on a small extension as it is on a large commercial building.

Please have a look at the case studies to get a feel for these projects.

We also have a gallery that will provide further inspiration.

While the case studies show the more unusual projects, the gallery is full of jobs that show more standard applications of our roofing systems such as standard businesses and homes where clever flat roof design made a huge difference.

The point is that flat roof design is no longer limited, whatever the style of building or nature of the building and its use, there is a flat roofing option to suit.


Thinking to The Future With Flat Roof Design

As with all planning, forward planning is key.

Some flat roofs can be walked on, but this requirement needs to be listed at the planning stage – you can’t just go and walk on a roof hoping it’s been designed to carry footfall.

The height and angle of the roof are also key considerations – flat roofs can be perfect when there are height restrictions, they maximize the space below the roof. However, storage space then needs to be taken into account with no loft area below the roof.

One of the great benefits of flat roof design is that it frees up internal space giving you the freedom to create an interior that does not have to take the roof into consideration.


Flat roof design need not be thought of as just a cost-effective option, it can also be the option that is the most aesthetically pleasing and benefits the rest of the property.

If building an extension, a flat roof can blend in with the property and the nature of the roof also ensures that views from upper floors are not affected.

The fact that the roofs can be walked on means that space can be reclaimed – an extension might eat into what was previously a garden seating area, but this same square footage is now available on the flat roof terrace.

The nature of quality flat roofs means they last a lifetime, so getting the design right in the first place is key.

At Topseal, all of our products have a minimum of a 20-year guarantee, but we expect them to last way beyond this, they should last a lifetime.

A few decades ago, flat roof design was easier in some ways. With fewer options, it was simply a case of choosing a fairly standard roof in one of a small range of colours.

Nowadays, flat roof design covers a huge range of different options, not to mention thousands of colours.

Flat roofs can blend in with properties or stand out as a statement; they can be shaped to form domes or slopes.
