Does a green roof make a roof waterproof?

No, a green roof is installed on top of the waterproof roofing. If a roof is not yet waterproof, waterproof roofing material must be applied before the green roof can be installed.

Green roof extends the life span of the roofing

A roof is continually exposed to ultraviolet light, rain, and temperature fluctuations. In the course of a year, a roof may be subject to temperature differences that amount to more than 100⁰C. Research shows that roof surfaces last about three times longer if a green roof is installed. The vegetation and this substrate protect the roofing material from all external influences.
