目前，世界上只有少数几个国家对屋顶绿化制定了相应的规章和准则。最早的屋顶绿化规章出现于20世纪90年代，是由德国波恩景观发展研究协会制定的FLL测试与德国标准“绿色屋顶实地规划、建造与养护准则”。该准则包括：绿色屋顶的类型、各种植被类型、建造技术要求、屋顶绿化相关步骤以及绿色屋顶的养护与维修。目前的屋顶绿化准则只有英文版，但其内容也同样适用于中欧地区的气候特征，且普遍适用于德国绿色屋顶绿化的系统建设。
无论这份屋顶绿化准则是否存在，各国都应该将屋顶绿化的相关规章与准则的修订与完善提上议事日程。这些准则 应当包括：绿色屋顶建造技术（例如承载能力、抗风保护、防火、防高温、噪声防护等）；以及屋顶建造技术（防水材料及其安装、竖梁、倾斜度、排水装置等）。上述内容在所有现行园林和景观建筑（如土壤、植物、草坪、种子混合物的保养和维护工程等 ）相关规章与准则的修订中也应予以考虑与补充。此外，根据各个国家的具体情况，应对高层建筑的屋顶安全与屋顶消防做出相应的规定。
Only a few countries have regulations and guidelines which apply to Green Roofs . The oldest regulations ,which were publish in the 1990's,are the German Standrad "Guidelines for the planning,execution and upkeep of Green Roof sites ",and are from The Landscaping and Landscape Dovelopment Research Society e.V.(FLL) in Bonn(Germany).The Green Roof guidelines contain the types of Green Roofs ,the various vegetation types,requirements for the building technique,Green Roof procedures as well as upkeep and maintenance for Green Roofs. The Green Roof guidelines are available in English but the content applies to the middle European climate region and the commom German Green Roof system build-up.
Whether Green Roof guidelines exist or not, the complementary country regulations and guidelines must also be considered.These guidelines can include:building technique(e.g.load bearing capacity,wind uplift protection fire protection,temperature,noise protection,etc);and the roof technique (waterproofing material and installation,upstands,slope,drainage,etc. ).Consideration must also be given to any existing regulations and guidelines for garden and landscape architecture(e.g.soil and plants, lawn,seed misture,upkeep and maintenance works,etc.).High buildings,according to the particular country,require various regulations regarding the security and fall protection on roofs.
