Green Versus White Roofs: What Are the Differences?

As a homeowner, it's possible that you are looking for ways to save on your energy costs for cooling. Two ways that you can do this are with a green roof or a white roof. With both of these types of roof having their own benefits, it helps to know the differences so you can decide which one is best for your house.

White Roofs

White roofs are coated using a paint that has reflective properties. These are designed in such a way that they will reflect the light that reaches your home's roof. This will help your home to be cool during the hot summers, helping you cut back on energy use for your air conditioner. A white roof will also be a cost-effective solution in terms of construction costs and maintenance.

If you go with the white roof, you could end up with a roof that is more durable than other materials. That is because a roof's lifespan is related to the amount of sun exposure it gets. If the sun is constantly shining on the roof, it can cause your roofing materials to eventually crack and warp. It will lead to early replacement. In comparison to traditional asphalt shingles, white roofs reflect the harmful light from the sun, helping roofs last longer. In addition to saving money on unnecessary roof replacement, you'll avoid putting old roofing materials in a landfill.

Keep in mind that the cost-effective nature of your roof is impacted by the climate your home is in. A cold climate will see minimal benefits, and you may need more heat in the winter to keep your home warm.

Green Roofs

A roof is considered a green roof when it is completely or partially covered using vegetation. The plants essentially act like a barrier between between the sun and your home, and they improve the air quality with additional oxygen as well. Many homeowners select a green roof more because of the environmental benefits than for the savings, but the savings are certainly a nice bonus.

The biggest problem with a green roof is that you will need your existing roof to be retrofitted to accommodate the necessary irrigation. This also requires additional maintenance because it's possible for the plants to die if they are ignored.
