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 the green roof trend has grown in popularity over the last few years due to the benefits that come along with them, including:
- Lasting longer than traditional roofs
- Providing natural insulation which decreases energy costs
- Catching rain water which can reduce the need for an intricate and pricey drainage system
- Offering a space for people and animals to relax
If enough green roofs are installed 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. 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, blue roofs have other potential advantages, 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.
