Eco-friendly roofing options continue to rise in popularity as companies become more environmentally conscious, and two different options stand out from the crowd.
Green and blue roofs are both excellent choices when it comes to environmental sustainability. However, they each have a separate set of goals. This article describes the distinction between the two and outlines the benefits of each.
Green Roofs
Green roofs are built as an extension of the foundation where plants and garden areas are constructed. The trend was first adopted in Europe and has made its way to the United States as a means to support environmentalism and resolve the issues that traditional roofs commonly present. This vegetative roofing method requires extensive water-proofing, a draining system, root barriers, plants, and lightweight soil.
It’s no surprise that this roof trend has grown in popularity over the last few years due to the green roof benefits that come along with them, including:
- Lasting longer than traditional roofs
- Providing natural insulation which decreases energy costs
- Catching rainwater, which can reduce the need for an intricate and pricey drainage system
- Offering a space for people and animals to relax
If enough green roof installations are done throughout urban areas, they could potentially improve the air quality and reduce heat traps.
Blue Roofs
Blue roofs are designed specifically to store water after rainfalls. The system is built with retention ponds that temporarily store water and use control devices to slowly release drainage from the roof over time. These devices can be compared to a sponge, absorbing and releasing water as needed.
Blue roofs are especially helpful in urban areas to help manage the commonly used combined sewer systems from flooding the system and draining into waterways.
Aside from regulating the overflowing sewer systems, there are other potential blue roof benefits, including:
- Reducing energy costs
- Utilizing stored water for landscaping
- Irrigating a green roof
Both green and blue roofs are intricate designs, and when installing these types of roofs, make sure you choose a roofing partner that is knowledgeable and experienced.
Key Considerations When Choosing an Eco-Friendly Roof
When deciding between a blue roof vs. a green roof, here are some important factors to keep in mind:
- Goals: Think about whether your focus is on managing rainwater with a blue roof or improving insulation and creating green spaces with a green roof. Additionally, a green roof is ideal for creating a recreational space with natural beauty.
- Cost and upkeep: Both roof types do have long-term benefits. Green roofs might need more care for plants, while blue roofs require regular checks for water management.
- Weather: Green roofs help in areas that need extra insulation, and blue roofs work best in places with lots of rain.
- Building support: Make sure your building can handle the weight of a green roof or the water storage system of a blue roof. Ask an expert to help you choose the best option.
