For homeowners, residential buildings and property managers.

The opportunity

Our cities have a rooftop opportunity.

As European cities face rising temperatures and heavier rainfall, thousands of rooftops remain underused. Green roofs can help turn these surfaces into living infrastructure, bringing environmental benefits without taking up additional ground space.

Reduce rooftop heat

Vegetation can lower roof surface temperatures and reduce heat entering buildings.

Raindrops on green leaves

Manage rainwater

Green roof systems retain part of the rainfall and can slow stormwater runoff.

Bee pollinating small purple flowers

Support biodiversity

Well-designed planting provides additional habitats for pollinators and other urban wildlife.

The Great Green Umbrella

One roof makes a difference. Thousands can transform a city.

Our vision is to turn 30% of urban rooftops green, creating a network of living surfaces that can help cities become cooler, greener and more resilient.

How It Works

Three steps to a greener roof

We make green roof projects easier by connecting building owners with trusted specialists and helping them navigate the process, from initial assessment to installation.

01

Assess the roof

We work with technical specialists to assess the roof’s suitability, structural requirements and feasibility.

02

Plan and finance

We identify the right technical partners, explore available public grants and subsidies, and help define the best solution for your building.

03

Install and maintain

Our specialist partners install the green roof and provide maintenance solutions to keep it thriving over time.

Three ways to work with us

Find your path

Residential buildings

A cooler top floor, a green view and a roof that lasts longer. We check whether your roof is suitable, find the installer and look for grants.

Company roofs

Turn your own roof into a building and sustainability asset, with documented results for your ESG reporting.

Adopt a roof

Sponsor a green roof on a building in your city. You get records, photos, agreed indicators and a roof your people can visit.

Other ways to join the umbrella

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.

Want to chip in?

Donate to the next roof in the umbrella. Every contribution goes towards greening it.

About us

We are Jungle Roofs

Jungle Roofs was founded by Lorenzo and Marco after noticing a simple contradiction: our cities get hotter every summer, while thousands of flat roofs stay empty in the sun.

We are an early-stage company developing our first projects, currently active in Spain and Italy. Our role is to connect building owners, companies and the specialists needed to deliver each roof correctly.

FAQ

Frequently asked questions

It depends on the size, the structure, the state of the waterproofing and the type of system. That is why we give a price only after a free roof check. If your roof needs renovating anyway, greening it often costs not much more than a conventional renovation.

Often, yes. Many cities and regions offer grants for green roofs. We check what is available for your building as part of the assessment.

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 technician checks it first.

A low, extensive green roof needs only a few visits a year. A walkable roof garden needs more care, like any garden. We plan maintenance with the installer from the start.

From the first check to the finished roof, usually a few months, depending on approvals and the season for planting.

The building owners. When a company adopts a roof, it funds the project and is recognised as its sponsor under a written agreement; the roof stays with the building.
