Pent or Apex – Which Shed Is Right For You?

When investing in a garden shed, the roof style affects the structure’s functionality. The choice between pent and apex roofs often sparks debate. This guide will break down their differences in design to help you find which one suits your needs best.

What Is ‘Apex’?

The word ‘apex’ actually derives from the Latin word for ‘peak’ or ‘tip’. The apex of a shed roof technically means the highest point. It has two sloping sides that come to a point at the top and form a triangle.

A shed roof apex also features two flat gables at its end, known as the gable ends or simply the front and the back. This roofing design allows for smooth water runoff and less damage.

What Is ‘Pent’?

If an apex roof has two slopes, a pent roof has only one and is a more modern, flat style. The highest point is in the front of the building, and then it descends to the back. Pent roofs are also referred to as flat roofs or mono-pitched roofs.

In a pent roof shed, the style features a horizontal header and is ideal for use as an extension. This means it can be attached to any flat wall of an existing building, such as a house.

The Differences in Their Design Characteristics

A pent and apex shed roof may look similar at first glance, but they have some key differences in their designs.


Apex shed roofs typically feature a steeper gradient than pent shed roofs. Their dual slopes allow quicker water runoff, unlike the single slope of pent roofs.

For instance, a heavy rainstorm is pounding down your apex shed roof. Thanks to its steeper gradient and dual slopes, the rainwater swiftly cascades down. Now, picture the same rainstorm whirring on a pent shed roof. The gentle slope allows water to drain off, but there’s a slight risk of water pooling on the roof’s surface. This might cause potential leaks if the rainfall persists.


The triangular shape of apex sheds provides ample headroom throughout the interior space. The highest point is at the centre, where you can stand comfortably without hitting your head. This extra headroom is handy if you’re using the garden room as a shed storage, such as for tall items.

In contrast, the single slanting surface of pent sheds slopes from one side to the other. This provides headroom near the entrance, but it gradually decreases towards the back. This may require you to stoop or crouch in certain areas, especially if you’re taller.

An apex shed roof is best if you need consistent headroom and to store long-handled tools. Go for a pent design for storage-focus use or if your garden has limited space.

Profile and fitment

The traditional shape of an apex shed roof may make it slightly tricky to fit them into tight spaces. You’ll need to measure carefully and plan where to put them so they fit just right without sticking out too far. It adds a classic look and is great if you have space to spare, nonetheless.

A pent shed roof offers a simpler and more uniform profile. It can fit into confined spaces or against fences without the risk of the roof peak protruding. The flat back of the shed also allows for a snug fit against walls or other structures.
