Why retrofit your rooftop with vegetation?
Modern ultralight green roof layers integrate seamlessly over most standard existing roof substructures.
LONGEVITY
Doubling waterproofing lifespan
Sedum foliage protects bitumen or PVC membranes from harsh UV degradation and thermal expansion, extending life to 40+ years.
EFFICIENCY
Natural passive summer cooling
Natural plant transpiration limits rooftop surface heat to under 30°C on hot summer days, cutting upper-floor air conditioning load up to 50%.
SUBSIDIES
Energy efficiency renovation grants
Vegetative retrofits qualify under national and EU climate adaptation and renovation loan programs for HOAs and commercial portfolios.
How the retrofit process works
Four structured steps from initial roof inspection to fully installed mature living architecture.
PHASES 1 & 2
Audit, structural load calculation and waterproofing
Our structural team inspects roof membrane integrity, drainage scuppers, and parapet transitions. Permissible dead loads are verified, and root barrier membranes are laid.
PHASES 3 & 4
Fast modular installation and full warranty
Drainage retention cups, substrate boards, and pre-grown sedum mats are lifted by crane and unrolled within 1-2 days. The roof immediately delivers 95% mature green coverage.
