Apex or pent? A straight answer from the workshop: how roof shape changes headroom, boundary height and rain run-off — and how to pick yours in a minute.
The honest comparison
Two silhouettes, one honest answer from the workshop floor: it's not which roof is better — it's where your building is going.
Ask us which is better — apex or pent — and you'll get the same answer we've been giving since 1995: neither, until you tell us where it's going. Both come out of the same West Midlands workshop, on the same tanalised frames and panel construction. The roof line doesn't make one shed better built than the other. What it changes is where the headroom sits, how the rain gets off, and how tall the building stands — and all three of those are decided by your garden, not the brochure.
The short version: going tight against a fence, or within 2 metres of a boundary? A pent almost always wins. Standing in the open where you want maximum height down the middle? Go apex. The rest of this guide unpacks why.
An apex shed has two sloping roof faces that meet at a central ridge — the classic silhouette a child would draw. That ridge puts the most headroom right down the middle of the building, which is exactly where you want it for tall storage, ladders stood on end, or a workbench running down the centre of a workshop. Rain and snow shed evenly off both sides.
A pent shed has a single slope running from a full-height front wall down to a lower back wall. The whole building sits lower overall, the best headroom runs the full length of the tall wall, and every drop of rain travels to one predictable side — one gutter run and the water's dealt with. That clean single line reads modern, and it tucks naturally under trees and below window sills where a ridge would poke through.
Structurally, there's nothing between them. Built properly, neither shape is stronger — the difference is geometry, not muscle. And both take the same coverings: traditional felt, or an EPDM rubber upgrade. If that choice is on your mind, our felt vs EPDM guide covers it properly.
Here's the fact that settles most apex-versus-pent debates. Under permitted development rules, if any part of a garden building sits within 2 metres of a boundary, the whole building must stay under 2.5 metres tall. That cap bites hardest on an apex, because the ridge is the tallest point — squeeze the ridge under 2.5m and you squeeze your headroom with it. A pent is made for the job: its highest point is one front wall, so it slips under the cap while still giving you full standing height exactly where you stand. Boundary rules have their wrinkles — conservation areas, listed buildings, larger footprints — so give our plain-English planning guide five minutes before you commit.
Shape drives footprint too. In our Build Studio, apex buildings run up to 10ft wide and anywhere from 4 to 20ft deep — long and narrow, with headroom down the spine. Pent flips that: up to 20ft wide and 4 to 10ft deep. So a wide-but-shallow run along a fence is natural pent territory, while a deep plot you walk into suits an apex. Stand in your spot with a tape measure and the footprint usually picks the roof for you.
Apex or pent, every frame is pressure-treated against rot before it leaves our workshop. Neither shape is built lighter than the other.
The same responsibly sourced boards go into both roof shapes. One standard, no shortcuts, whichever silhouette you choose.
Both shapes take traditional felt or an EPDM rubber upgrade — the 50-year roof — so the covering question is separate from the shape question.

No — that's the most persistent myth in shed buying. Built properly, neither shape is stronger. Ours share the same tanalised framing and the same panel construction whichever roof you pick. The shape changes where the headroom sits and how the water gets off — not how the building stands up to weather.
In our range, price is driven by size and material far more than by roof shape — a like-for-like footprint comes out close either way. The honest advice is to pick the shape your spot needs first, then set your size in the Build Studio and flip between the two to see the live price for each.
Yes to both. The full-height front wall of a pent is a natural home for windows — light falls straight onto whatever runs along it — and doors go wherever you place them. In the Build Studio you position doors and windows panel by panel on either shape; double doors just need a wide enough clear stretch of wall — most pents have plenty across the front.
It depends where you'll stand. A bench down the centre with racking either side wants an apex, which puts peak headroom directly over your head. A bench along one long wall wants a pent, whose tall front wall gives you standing height along its whole length — and pent's wide-but-shallow footprints suit that layout perfectly.
Easily, and it's worth doing. A pent is the simplest guttering job going: one slope means all the rain arrives at one edge, so a single run into a water butt finishes the job. An apex sheds water both sides, so plan a run on each. Either way you keep drips off the walls and water away from the base.
Stand in the actual spot and run down this list — most people have their answer by the third question.
