Is Your Commercial Building Ready for a Green Roof?
Installing a green roof on your commercial building has a lot of benefits for both the environment and for the building itself. Green roofs have actually been around for thousands of years. Luckily we’ve made some technological advances and have modern day technology on our side.
Main Types of Green Roofs
There are two main types of green roofs: a modular system and a traditional system. A modular system houses plants with deeper roots such as trees or large gardens. You typically find these in commercial buildings where the roof acts as a green space for people to visit, creating an atmosphere like a verdant park right on the building’s roof, adding more space for people to visit.
The traditional system covers an entire section of the roof and typically holds medium-sized gardens or smaller. It is normal to keep the variety of plant life at a minimum on this type of roof, which means less maintenance. Drainage and plant health typically thrive in this type of green system.
Advantages of a Green Roof
- Reduce the Urban Heat Island effect. Green roofs can put excess rainwater back into the air, helping to cool temperatures.
- Manage the rainwater. A green roof helps to slow rainfall runoff by catching rainwater on the roof and filtering it slowly through the plant system.
- A green space. In the middle of an urban area, people crave trees and plant life. By using the top of a building, you can provide a valuable service to the community, which is unseen anywhere else.
- Create a sense of community. Green roofs can provide a space for community gardens, recreational space, educational space, restaurants and more.
- Energy efficiency. Green roofs provide insulation for buildings as well as reducing the need for air conditioning by over 75%.
- Green roofs typically last longer than a standard roof.
Disadvantages of a Green Roof
- To start a green roof, you typically need a rather hefty budget.
- If your building cannot withstand a heavy load on the roof, adjustments may be necessary, further raising the budget.
- Extra maintenance costs are a factor when keeping the roof healthy and working properly.
If your commercial building is in need of a new roof, it may be the right time to consider a green roof. Weigh the pros and cons of your particular building’s situation, or contact a commercial roofing specialist for an opinion about the weight your roof can hold.
