Green Roof Construction: 5 Tips Green Roof Construction: 5 Tips
When you live in an urban area and you want to have a garden, your best option would be a green roof construction. More and more urban dwellers are opting for this type of garden because aside from the aesthetic benefits that you’ll get from it, it also provides other advantages as well. Rooftop gardens help reduce pollution in the air by absorbing carbon dioxide and give additional insulation inside the home by reflecting heat and cold. If you do decide to have one constructed on the roof of your home, here are some tips to keep in mind.
1. Check Building Codes
Before you begin with the construction of a green roof, it is imperative that you check the local building codes first. Make sure that you follow any regulation that pertains to the use of the roof. Don’t start with the construction without first obtaining a written permission from the landlord, building owner, or condominium association. It would also help to get professional help from an architect, engineer, or contractor so you can determine if the roof and building structure are strong enough to withstand the heavy weight of a roof garden.
2. Create a Design
The basic elements of a garden design include roof surface, lighting, water, plants, containers, and electricity. All these elements should be kept in mind when constructing a green roof. It is also a must to have sufficient spacing around the plants for them to grow and develop. There should also be ample walking areas so that tending to the plants and watering them would not be too challenging.
3. Use Lightweight Materials
When choosing containers, weight is of prime importance. Use containers that are light to prevent the scenario of overloading the roof. Plastic and fiberglass containers are more favorable than those that make use of pavers. See to it too that they provide good drainage but at the same time, hold sufficient moisture. As for the soil, avoid using garden dirt. Instead, opt for lightweight potting soil. Also, make use of Styrofoam peanuts in lieu of rocks or pottery shards for the drainage.
4. Plan Provisions for Watering
Water is necessary for any type of garden, more so for rooftop gardens that are subject to hotter temperature and drying wind. Although watering is normally not a tedious task, bringing heavy loads of water up to the roof can prove to be exhausting. To resolve this problem, you can install water system storage or automatic watering system on the rooftop. Again, ensure that weight won’t be a problem for this.
5. Choose the Right Plants
Apart from the construction itself, you also have to consider things like which plants to choose for the garden. Your choice of plants can play a big role in your success. Some of the best choices to use include mosses, lichens, sedums, wildflowers, and calcareous grass. All these plant varieties can withstand the conditions present in a rooftop garden.
