Green roofs on sloping and steep surfaces. Ready-made solutions and consulting

16 of December '20

ZinCo green roof systems on sloping surfaces


Modern construction industry is increasingly taking advantage of the benefits of green roofs. Properly designed and executed, they offer virtually nothing but advantages. Energy efficiency, thermal insulation, waterproofing, natural air conditioning through roof breathing... While green roof systems on flat surfaces are already common and used on building structures in Poland, green roofs on sloping and steep surfaces are still rare. This is associated with concerns about the durability of solutions, difficulties in design and implementation. So it is worth reaching for proven systems that guarantee the proper operation of the roof. The company Green City Life Sp. z o.o. proposes a solution to the problems of this type of construction - the use of products from the leader in this field - systems from ZinCo, which can be used on roofs with a slope angle of up to 45%.

The basics of good green sloping roof design

In order for a pitched or steep roof to function properly, several basic elements must be taken care of. First, the waterproofing (aka waterproofing) must be of the highest quality and have resistance to root overgrowth. The next factor is to use self-supporting green roof structures that do not interfere with the roof sheathing. Another, ensuring proper vegetation of plants in such difficult conditions as sloping slopes of a green roof. Last, but equally important, is the efficient drainage of excess water from the roof.

Can a green roof be sustainable? Absolutely. A perfect example is the two-decade old green roof of the University Library in Warsaw, Poland.
