GREEN ROOF TYPES

Five ways to
green a roof.

From a featherweight sedum carpet to a buzzing biodiverse meadow — five complete green roof types, built two ways. Compare them below and, if in doubt, send us photos and technical information for tailored advice.

TWO WAYS TO BUILD

Tiles, or layers.

Every type is one of two build methods. Which suits you depends on your roof's size, slope and how hands-on you want to be.

Tile system

Pre-grown trays with drainage, substrate and plants built in. They click together and interlock — green the same day, and the only method that handles slopes up to 30°.

TYPES 1–2 · SEDUM · UP TO 30° PITCH

Layered system

The classic build-up, laid layer by layer on site: protection, drainage, substrate and the vegetation of your choice. More design freedom and more biodiversity, for flat roofs (0–5°).

TYPES 3–5 · SEDUM TO BIODIVERSE · 0–5° PITCH
THE LINE-UP

Weights are structural (fully saturated) — always confirm your roof's load capacity with us before ordering.

TYPE 01 · TILE SYSTEM

Lightweight Sedum Tiles

Our featherweight tray — pre-grown with at least 7 sedum species, delivered 80% grown-in. When your roof's load capacity is tight, this is the one: green the same day, and it happily follows slopes up to 30°.

TYPE 02 · TILE SYSTEM

Sedum Tiles

The full-bodied tile: trays filled to 8 cm of substrate with at least 7 sedum species, buffering 28 L/m². Compared with our lightweight option, more water is held here, making it more resilient to drought. Suitable for flat and pitched roofs up to 30°.

TYPE 03 · LAYERED SYSTEM

Layered Sedum Roof

The classic extensive build-up, laid layer by layer with at least 7 sedum species. A 70 mm system that tolerates sun and light shade — the go-to for larger flat roofs.

Biodiverse Roof — Sedum & Herb

Where a roof becomes habitat. A semi-intensive build-up planted with sedum, grasses and native herbs — biodiverse and lively, buffering 50 L/m² across 110 mm. Choose your planting from our plant menu.

Biodiverse Roof — Herb

Our richest, deepest roof: a full herb-and-grass meadow on 145 mm of substrate, buffering 60 L/m². The most water held, the most life supported — a genuine landscape upstairs. Needs a roof that can carry it.

STILL CHOOSING?

The plants decide the character.

For layered types you pick the planting — from budget sedum cuttings to a full herb meadow. See the trade-offs in budget, care and biodiversity.
