What Is a Green Roof?

If you’re on the market for a new roof, you’re certainly not alone. Did you know that the need for quality roofing is supposed to increase by almost 5% through 2021? Between harsh weather conditions and older homes meeting their limitations, now is the perfect time to invest in a new roofing system.

The classic roofing option is asphalt shingles. These materials are perfect for repelling moisture and preventing mold and fungal growth across your roofing system. While they do need to be cleaned often, they do a great job protecting your home as long as they are well-maintained.

However, you might have heard of green roofing becoming more of a trend. While this option isn’t for every home, this eco-friendly roofing choice is a nuanced way of protecting your home and giving back to the environment. Here’s what you should know about green roofing and if it’s right for you.

Green roofing: What is it?

To put it simply, a green roof is a type of roof that enables plants to grow on top of it. These roofs are usually inundated with drainage layers to prevent heavy, water-laden soils from putting too much pressure on your home. However, modular green roofing options are becoming increasingly popular among eco-friendly homeowners.

There are two primary types of green roofs and they are determined by the weight of the vegetation. Extensive green roofs spread out the weight so only 25 pounds of pressure are put on every square foot of roof. However, intensive green roofs can hold as much as 150 pounds per square foot. As such, intensive green roofs are harder to maintain then extensive options.

Keep in mind that extensive green roofs are designed to become overgrown and should only be maintained once per year. If you’re more of a hands-on homeowner that wants to enjoy the flora on their green roof, an intensive roofing system might be the better option.

There are a few primary components to a green roof. These consist of the vegetative layer, soil or another type of growing material, a filter membrane, a drainage system layer, a waterproofing layer, and a structural form of roof support. While these roofs aren’t cheap, they can certainly be beneficial to helping the environment and contributing to a more eco-friendly lifestyle.

Why invest in green roofing?

Green roofing offers a few essential benefits to homeowners:

  • Homeowners can appreciate the aesthetics of a green roof
  • Green roofs contribute to lower utility bills since they help regulate home temperatures, especially in hot climates
  • Green roofs can be treated as a garden for the whole family to enjoy
  • This roofing option helps relieve the stress put on storm drains since they catch and use the water effectively

Green roofs are growing in popularity among residential homeowners, but they are already making their way into major cities as well. This is because they make commercial spaces more desirable and disrupt the urban heat island effect that leads to higher temperatures in cities.

Just about anyone can benefit from a green roof, but these roofs work particularly well in areas that get moderate amounts of rainfall. However, the type of plants can also be varied to accommodate hotter environments.

Green roofs aren’t for everyone but they are changing up the way roofers do business. Think about this option the next time you need to replace your roof.
