When you plan a green roof on your house you should hire a landscape architect or designer. You need someone who specializes in the field, someone who knows the construction requirements and regulations, assembly systems, drainage rules, local conditions, plant species and maintenance well. Every green roof is a multi-layer construction made of a variety of materials. The cost is about two to four times higher than that for the construction of a conventional roof. Before starting a construction project, you need to calculate your finances so that the project fits into your budget.

Green roofs are divided into two main groups by the type of plants – intensive and extensive. The extensive green roof is recognized as it features a layer of grass uniformly distributed on a thin layer of soil with 5 to 15 centimeters thickness, while all other plants are placed in separate containers. The roof needs watering only during the period of the growth and requires a regular maintenance like cleaning weeds and mowing grass. The low cost and ease of maintenance are great advantages of this type of green roof.

Intensive  roof gardening is characterized with a thick layer of soil and you could grow not only grass but also shrubs, and even certain types of trees. This is a complex system which requires special watering and care. The depth of the soil layer can be up to 60 centimeters and the planning and design involve careful calculation and expertise. These roofs usually include several layers – the first layer is made of reinforced concrete slab or plywood deck to provide stability of construction. Then we have different layers providing insulation, waterproofing, drainage, etc. Such constructions are much more complex and expensive and in addition require much more maintenance.

The choice of plants for green roofs will of course depend on the local conditions. Not all flowers, shrubs and trees are ready to adapt to new conditions of survival. Choosing the seedlings will be guided by the following criteria – a small root system; great drought and frost resistance, ability to resist wind attacks, total simplicity. Irrigation needs are greater in southern regions. Low growing species like grass, creepers dwarf shrubs and trees are a good choice as well as succulents, herbs and moss. To add color you can plant carnations, violets, yarrow, daffodils, ornamental flowering plants like campanula, etc.
