How we work
Transparent process - you know what happens at each stage.
Free consultation
We talk about the building, the condition of the roof and your expectations. At this stage we already point out possible solutions and what needs to be checked on site.
On-site inspection
We check the substrate, falls, drainage, flashings and leak points. Without this, any quote would be guesswork.
Quote and system selection
We prepare a paid, individual quote with a breakdown of the scope and select the covering and insulation system for the building.
Contract and schedule
We put the scope, schedule and warranty terms in writing - up to 15 years, depending on the chosen system.
Execution
We carry out the roofing works with a focus on details: flashings, service penetrations and drainage, because that is where leaks most often start.
Handover and aftercare
We hand over the works together with you. On request we carry out periodic inspections, and we take failure reports 24/7.
What we need from you
Assessment of the roof structure load capacity.
What an extensive roof is
It is the lightest type of green roof: a thin substrate layer and low, hardy vegetation - usually sedum. It does not need regular watering or mowing.
What a green roof gives you
The vegetation layer retains part of the rainwater, shields the waterproofing from UV radiation and reduces roof heating in summer.
Greenery, energy and servicing on one roof
We divide the roof into zones: green fields, rows of photovoltaic panels and a technical zone with equipment. This way servicing the installations does not require walking on the vegetation.
The foundation: watertight waterproofing
Beneath the greenery lies the waterproofing, which is hard to reach once the plants are in. That is why we build it with particular care. Warranty of up to 15 years, depending on the system.
Technical standards
Hard parameters and technologies - no fluff.
You invest safely
Custom quote, long warranty, and support right after delivery.
Warranty
Warranty of up to 15 years, depending on the system used and the type of building. The terms are set out in the contract.
No commitment
The consultation is free and non-binding. The quote is a paid service.
