What is a Roof Garden?
A roof garden is a roof that is partially or completely covered with vegetation and soil, or a growing medium, planted over a waterproofing membrane.
Specifying a system that provides environmental benefits such as clean air, reduced stormwater and energy conservation is what an increasing number of building owners are asking for.
The Viking Roof Garden system offers both functional and aesthetically appealing benefits.
Storm Water Management
One of the key benefits of roof gardens is the reduction of stormwater run-off. The soil acts like a sponge to absorb, delay and slowly release stormwater, therefore reducing peak loads on city drainage infrastructure.
Air and Water Purification
Roof gardens help to purify the air by converting the CO2 into oxygen thus reducing greenhouse gases. Additionally, the soil acts as a filter to assist with purifying the water and neutralising any potential acid rain impact.
Longer Roof Life
A roof garden protects the roof membrane from climate extremes and physical abuse which increases the life of the roof and its long term performance.
Insulation – Both Sound and Temperature
Tests have shown that a roof garden’s soil and plants can reduce indoor noise pollution. A roof garden will also assist in keeping the building warmer in winter and cooler in summer.
Sound and temperature insulation performance can be further enhanced with Polyiso rigid insulation panels incorporated underneath.
Reduces Urban Heat and Energy Consumption
Impermeable urban surfaces such as concrete and bitumen, absorb a significant amount of heat during the day which is radiated back into the air. This increased outdoor temperature results in more energy being required to air-condition a building.
Roof gardens help insulate and shade buildings, and the plants on the roof gardens transpire, thereby cooling the surrounding air - further reducing the energy consumption of the building.
A roof garden’s wonderful look ties the building into the natural environment, providing a haven for bees and birds in metropolitan areas; and for commercial buildings, a pleasant outdoor area for staff.
Using the roof surface to accommodate an extensive roof garden means you are utilising the building’s “5th wall” to create outdoor public space instead of displacing further real estate.Read More
We stand behind our product and Viking Enviroclad is covered by a robust 20 year Product Warranty.
The waterproofing sector is possibly the most litigious of the construction industry. There are no second chances. So Viking products can only be installed by a Viking Approved Applicator. This is all about taking care of the detail and working with our team of professional, trained applicators to ensure that a watertight finish is achieved.
Viking Roof Garden Systems
At Viking Roofspec, we offer a range of roof garden systems which have been adapted to meet specific project requirements.
We recognise that each roof garden is unique, so we work with all project stakeholders to create a custom system that meets the New Zealand Building Code requirements and the needs of the building owner.
