Meet the Pitchedgreen Family
There are three types of pitched green roof systems. Pitchedgreen Amnis is our vapor-tight system with a reinforced vegetation layer. It provides extra stability on steep roofs and is ideal for new build projects. Pitchedgreen Aura is the vapor-permeable system, a natural alternative to roof tiles that is easy to mount on battens and fully recyclable. Pitchedgreen Tile is the pre-grown green roof tile: lightweight, instantly green, and suitable for slopes up to 45 degrees. All three systems turn pitched roofs into sustainable, climate-active surfaces that deliver long-term performance and a natural look.
From gentle slopes to 45° rooftops – every surface can be part of the green city
DISCOVER THE IDEAL PITCHED ROOF FOR YOUR PROJECT
Feeling a bit overwhelmed with ideas? Don’t worry! We’ll help you find the right solution for your project. With just a few quick questions, we’ll help you find the right approach and system for your pitched roof. You’ll receive customized advice to make green work for you.
Double the power of your roof
Why choose between green or solar when you can have both? Sempergreen’s pitched green roofs create the perfect base for solar panels. The vegetation keeps the panels cooler, increasing efficiency and energy yield. At the same time, the green layer absorbs rainwater, supports biodiversity, and adds visual appeal to any project. The result is a multifunctional roof that delivers on performance, sustainability, and design. Ideal for residential, commercial, and public buildings where every square foot counts. Together with our partners, we help you create roofs that generate energy and make an impact.

QUESTIONS ABOUT PITCHED GREEN ROOF
Discover answers to the most common questions here. Is your question not listed? Our experts are happy to assist you personally.
How much does a sloped green roof weigh?
The weight of a vapor-open sloped green roof ranges from 110 to 220 lbs/sq ft, making it ideal for sustainable renovation projects. Vapor-closed sloped green roofs weigh between 220 and 297 lbs/sq ft. This means that almost any sloped roof can be transformed into a vibrant green roof.
Can a Sloped Green Roof Be Combined with Solar Panels?
Yes. Sloped green roofs can easily be combined with solar panels. The plants provide natural cooling, which increases the efficiency of the panels and boosts energy output.
Can a sloped green roof replace roof tiles?
Yes. A sloped green roof can be used as an alternative to traditional roof tiles. With the water-retaining green roof tile system and the Sempergreen MGT Green Roof Tile, there are durable solutions available.
The green roof tile system is made from recycled material, water-retaining and vapor-open—just like a roof tile—and can be easily mounted onto battens. The system is fully recyclable, suitable for both new constructions and renovations, and compatible with solar panels.
The MGT Green Roof Tile consists of prefabricated modules with ≥ 95% plant coverage upon delivery. These modules are installed on battens with a spacing of 330 mm and are suitable for roof pitches from 25° to 60°. They are an excellent solution for residential, commercial, and renovation projects, combining aesthetics, sustainability, and water management in one.
Is a Sloped Green Roof Suitable for Renovation?
Yes. Thanks to lightweight system options, vapor-open sloped green roofs are very well suited for sustainable renovation projects, even when the existing roof structure is maintained.
What is the maximum slope possible for a green roof with vegetation blankets?
Sempergreen sloped green roofs can be installed up to 45°, depending on the chosen system and the load-bearing capacity of the roof structure.
