Living Roof

A living roof, also known as a “green roof,” are among the most sustainable roof materials available. A living roof features live vegetation planted on top of a waterproof membrane. The vegetation makes an excellent insulator, preventing the drastic temperature swings found on conventional roofs.

Installing a living roof is more complex than the other options on our list. For starters, you’ll need to ensure your structure is strong enough to support its substantial weight. A stark visual contrast to other roofing options, a living roof could be the perfect fit for those looking to embrace an environmentally-friendly concept.

Pros

• Great insulator;
• Environmentally friendly;
• Long-lasting.

Cons

• Expensive;
• Challenging to install.

Cost: According to Pacific Horticulture, between $30 and $40 per sq. ft.
