Residential buildings

Turn your roof into a greener, more comfortable part of your building

We check whether your roof is suitable, find the right installer, look for grants and coordinate the project from the first visit to the last plant.

Is this for you?

A good fit if…

You have a flat roof or terrace

On a house or an apartment building, used little or not at all.

You decide, or can bring it to a vote

Homeowners, the building’s board or president, or the property manager.

Your roof needs work anyway

If the waterproofing is due for renovation, it is the best moment to green it.

What you get

What a green roof gives your building

A cooler top floor

Plants and soil keep the roof shaded, so far less heat reaches the homes below.

A roof that lasts longer

The green layer protects the waterproofing from sun and temperature swings.

A greener, more valuable building

A green view, rainwater held on the roof and a more attractive building to live in.

What your roof could become

A few examples from other cities, to give you ideas for yours.

A greener view from above

Neighbours in taller buildings look out on a living meadow instead of grey gravel.

  1. Vegetation: plants chosen for the roof and climate
  2. Substrate: light growing medium, not garden soil
  3. Filter fabric: keeps fine soil out of the drainage
  4. Drainage & water storage: holds rainwater, drains the excess
  5. Protection mat: shields the waterproofing
  6. Root-resistant waterproofing: stops water and roots
  7. Your existing roof: checked for load before we start

A green roof is not soil spread on a terrace. It is a tested system of layers that protects the building, holds rainwater and keeps the plants alive with little care.

It sits on top of your existing roof. That is why the first thing we check is whether the structure can carry the extra weight, and whether the waterproofing is in good shape or due for renovation anyway.

Which type fits your roof

Three kinds of green roof

Extensive green roof with sedum on a residential building in Stockholm

Extensive

Low plants such as sedums, grasses and wildflowers.

  • About 8–15 cm of growing medium
  • The lightest option: roughly 80–150 kg/m² when wet
  • A few maintenance visits a year

Best for: roofs you don’t use every day, or with limited load.

Semi-intensive green roof with grasses and perennials on a terrace

Semi-intensive

Perennials, aromatic herbs and low shrubs.

  • About 15–25 cm of growing medium
  • Roughly 150–250 kg/m² when wet
  • Some watering and seasonal care

Best for: a shared terrace the neighbours can enjoy.

Intensive

A real roof garden, with shrubs, lawn and even small trees.

  • 25 cm of growing medium or more
  • From about 300 kg/m² when wet
  • Garden-level care and irrigation

Best for: strong structures and roofs people use every day.

Indicative values. The exact system, weight and maintenance depend on your roof and are confirmed by the installer after the roof check.

Your investment

A tailored proposal for your roof

Every roof is different, so we don’t work with fixed prices. After the free roof check, you receive a tailored proposal based on your roof’s size, structure, waterproofing and the system that suits it best.

If your roof is due for renovation, it’s the ideal moment: adding a green layer often costs only slightly more than a conventional renovation, and helps protect the waterproofing for longer.

We also look into the public grants and subsidies your building may be eligible for.

FAQ

Questions we often hear

Most flat roofs can host some kind of green roof. It depends on how much extra weight the structure can carry; lightweight systems exist for roofs with limited capacity.

A well-designed green roof sits on top of the waterproofing with a root barrier and protects it. We always check the existing waterproofing first.

Works on a shared roof usually need the approval of the other owners. We prepare a clear summary you can present to them.

A low, extensive green roof needs only a few visits a year. We plan maintenance with the installer from the start.

It depends on the city and the building. In most cases a green roof on an existing building needs a simple communication or a minor-works permit. We check what applies to your building and prepare the documents with the installer.

The installation itself usually takes from a few days to a few weeks, depending on the size of the roof. Before that, the roof check and the approvals from the owners and the city take most of the time. After the check we give you a realistic timeline.

Have a roof but no budget?

Offer it for adoption. We look for a company that wants to sponsor a green roof on your building.
