Apex or pent roof: which should you choose?
The roof is the biggest single decision on a concrete garage — it changes the look, the headroom, the price and where the rain goes.
Last updated 11 August 2026
An apex roof is a pitched roof that rises from both sides to a ridge along the middle, giving the classic house-shaped outline. A pent roof slopes in one direction only, from a higher front to a lower back. Apex looks more traditional and gives more height inside; pent is lower, cheaper and fits under windows and boundary lines.
That's the whole distinction. The rest of this page is about which one suits your plot.
What is an apex roof?
An apex roof rises from both eaves to a central ridge, forming a shallow triangle when you look at the gable end. It's the shape most people picture when they think of a roof, and it's the reason an apex concrete garage tends to look like part of the house rather than a box in the garden.
On a Nucrete apex garage the extra height in the middle is genuinely usable — it's where people put roof storage, a light, or simply enjoy not stooping. The trade-off is that an apex building is taller overall, which matters if you're working under permitted development limits or beneath a neighbour's window.
What is a pent roof?
A pent roof slopes in a single direction across the building, so the front wall is taller than the back. Older literature sometimes calls this a sloping roof garage. It sheds water to one side, which lets you decide exactly where the rain goes — usually away from a path, a boundary or a neighbour.
A pent roof concrete garage is the most economical way to buy a Nucrete building, and it's the practical answer when the garage has to sit under a window, beneath an overhanging tree, or hard against a boundary where height is limited.
Which roof should I choose?
| Choose apex if | You want the traditional pitched look, you want maximum internal height, or the garage will be seen from the house and the road. |
|---|---|
| Choose pent if | Height is restricted, the building sits under a window or against a boundary, or you want the most economical option. |
| Cost | Pent is the cheaper of the two on a like-for-like size. Request the price list for figures in your delivery area. |
| Water | Apex sheds to both sides; pent sheds to one. Guttering can be fitted either way. |
| Both available as | Single, double, extra-height, lean-to and Elite specification. |
What is the roof actually made of?
Nucrete roofs use Profile-5 cement fibre sheets over the concrete panel structure. They don't rot, they don't need felting or re-covering, and they carry the same 10-year factory guarantee as the rest of the building.
That's a deliberate choice rather than a cost one. A concrete garage is expected to last 50 years or more with basic annual maintenance, and there's little point putting a roof on it that needs replacing in fifteen.
Can I have a flat roof?
Not truly flat, no — and that's on purpose. Every roof needs a fall so water runs off rather than sitting on it, which is why a pent roof is the flattest-looking option we build. From ground level a pent roof garage reads as flat, but it's shedding water the whole time.
If you've been quoted a genuinely flat roof elsewhere, ask what the covering is and how long it's guaranteed for. It's the part that tends to fail first.

Roof questions, answered
What does apex mean on a garage?
The apex is the highest point of a pitched roof — the ridge line running along the middle where the two slopes meet. An apex garage is simply one with that traditional pitched roof shape.
Is an apex or pent roof better?
Neither is better as a building; they suit different plots. Apex gives more height and a more traditional look, pent is lower and more economical and works where height is restricted. If the garage will be visible from the house, most people prefer apex.
Does the roof style change the price?
Yes. A pent roof garage is the more economical of the two at the same size. The difference varies by size and delivery area, so request the price list to see both side by side for your postcode.
Which roof is better for a boundary?
Usually pent, because you can face the low side at the boundary and shed water back onto your own land. It also keeps the overall height down, which helps with permitted development and with neighbours.
Do I get guttering with either roof?
Guttering is an option on both. On an apex you would normally gutter both sides; on a pent, just the low side. See our guttering and fascias page for how it's priced.
