Tips to construct Green roofs
Things to know before the construction of green roofs:
If you want to do it yourself, remember it is entirely different from painting your home’s roof with green color. The process has various requirements and techniques that should be appropriately done to install a green roof in your home.
First of all, make sure that either your home’s roof can support the green roof or you can say it can hold a garden on its top. If so, then proceed in a forward direction. Another thing to know is the shape of your home’s roof because flat roofs offer the best suitability to green roofs.
The reason is that the steeper and low-sloping roofs need different mechanisms for installing a green roof than flat roofs. Therefore, before constructing a green roof on your home, you should consider them because they matter a lot in green roofing.
Materials and tools required for installing a green roof:
Whether you install a green roof on your own or from a roofing company, given below materials and tools are needed:
- Drainage mat
- Edging material, including wood or mesh gutter guards
- Plant trays if you want
- Pond liner
- 6mm plastic sheet
- ¾ inch foam insulation
- Tape measure
- Garden rake or hoe
- Garden trowel
Step-by-step process of installing green roof:
The extensive and intensive green roofing types come up with a standard installing process with a bit of difference in some things. Additionally, the shape of the roof also makes a slight difference, but here we will explain only common steps for a flat roof that can be done DIY.
- In the first step, you will install the waterproof membrane that plays the savior’s role in keeping your structure undamaged. For this purpose, you can use the plastic or rubber sheet as a waterproof membrane. Next, place that sheet on your home’s roof deck.
- Now install the 6 mm plastic sheet on the waterproof membrane to make a root barrier between plants and the roof structure. It will save your roof from damage.
- In this step, you will add the foam insulation sheet. Cover the roof deck with the two layers of one or more thin sheets of ¾ foam insulation. It will make the connection with damp soil on its surface without making it reach the roof structure.
- You have to install the drainage mat, also known as the dimple mat. Set this mat on the top of foam insulation by keeping the place for capillary spaces. The soil can clog the mat because it has pores, so to prevent this situation, place the mat with the felt side on the upper side.
- At this moment, you will take the mesh gutter guards for framing the sides of the roof. Next, you can use wood or other edging material to prepare the roof sides. This framing will allow the drainage to keep the soil in place.
- You will add the soil to the whole garden space on the roof. You should distribute the soil evenly throughout the top without keeping any space free.
- In the last step, you will set the plants according to your preference. The only thing to remember while setting the plants is to place the taller ones in the back and shorter ones in the front. The reason is that in this way, all the plants will be able to get enough sunlight.
- Then water the soil you add on the roof around the plants to settle it down.
Installing a green roof in your home seems a straightforward task, but it doesn’t because it requires some unique techniques to hold on the top firmly. Therefore, installing a green roof by any skilled roofing company is advised instead of yourself.
