Extend roof membrane lifespan past 40 years, ensure natural passive summer cooling, and create high-value rooftop environments for residents. Grant-compatible sedum systems for apartment communities and private houses.
During comprehensive residential building modernizations, green roofs contribute significantly toward municipal energy efficiency and stormwater retention goals, fulfilling grant criteria and boosting property value.
PASSIVE SUMMER COOLING
Natural Cooling for Top-Floor Apartments
Unshaded dark roofs heat up to 80 °C in midsummer, turning top-floor units uncomfortably hot. A sedum blanket limits roof surface temperatures to 30-35 °C through evaporative cooling, substantially lowering indoor temperatures.
HOUSING ASSOCIATION RESERVE FUND
Prevent Costly Roof Replacements for Decades
Standard exposed bitumen or PVC roofing membranes require costly replacement every 15-20 years due to solar UV embrittlement and thermal shocks. Waterproofing protected beneath a certified green roof lasts 40 to 50 years, saving housing communities tens of thousands of euros.
Rooftop Configurations for Residential Living
Tailored engineering systems for flat roofs, pitched villas, balconies, and community terraces.
System 01
Apartment Flat Roofs
Ultralightweight systems (45-55 kg/m²) engineered for standard concrete slab structures without structural alterations.
System 02
Pitched Villa Roofs
Sloped sedum systems featuring anti-shear retention grids engineered for pitches up to 45 degrees on private homes and pavilions.
System 03
Garages & Outbuildings
Rapidly installed modular sedum trays for residential carports, garden workshops, and waste management shelters.
System 04
Rooftop Terraces
Integrated designs combining timber decking, patio pavers, and living sedum zones into private communal sanctuaries.
Frequently Asked Questions
Answers for housing association boards, property managers, and private homeowners.
Most standard reinforced concrete slab apartment roofs easily bear the load. Green Haven offers specialized ultralight systems with saturated weights from 45-55 kg/m² that do not require structural frame reinforcement.
A green roof satisfies energy efficiency, on-site stormwater retention, and biodiversity criteria during comprehensive residential retrofits, helping achieve higher EPC ratings and qualify for municipal subsidies.
A sedum green roof is self-sustaining and low maintenance. Housing associations can perform the simple 1-2 seasonal visual checks and spring fertilizing themselves, or retain Green Haven for complete annual care.
Pitched roofs are equipped with anti-slip cellular grid retention mats and reinforced shear battens that securely lock substrate and mature sedum blankets in place even during torrential downpours.
