Did you know that rooftop gardens became popular in the US in the 1890s and that is where Madison Square Garden got its name?
Let’s unpack green roofs and green roof waterproofing with you.
Roof gardens would generally be classified as intensive gardens. They would need to hold soil up to 1m deep to be able to support vegetation or planter boxes, trees, as well as structural work like concrete seating areas, decking and paving.
The waterproof membrane required to support a flat roof garden would firstly need to support the weight per square metre and be durable enough to withstand any plant treatments and weather conditions. In larger commercial or strata type buildings, the membrane would also need to support any structural movement.
Green roofs or roof gardens are generally installed on flat roofs. Flat roofs are energy efficient, are more affordable (excluding the landscaping costs) and require less maintenance than sloped roofs. With the right maintenance plan in place for the roof design, the roof can last for decades.
Green roofs or living roofs are known to insulate a building, requiring less cooling or heating, resulting in less emissions.
They improve sound, generate oxygen and act as a filtration system for rainwater by capturing pollutants. Green roofs can also decelerate water runoff, which has been proven over recent months with the wet weather conditions we’ve been experiencing.
With all the great and versatile benefits of choosing a green roof, we must emphasise the importance of getting flat roof waterproofing right and selecting the correct flat roof waterproofing solution, membrane and maintenance plan. The alternative will become incredibly costly in the long run.
