Check out these 7 salient points that should be considered before making your choice of sustainable roofing materials:

1. Recycled Content

Ensure that the potential roofing materials have higher recycled content. Normally, the higher the recycled content in roofing material, the better its ranking is on the eco-friendly scale, thus making it all the more efficient. However, durability should also be considered in combination with the percentage of recycled material, as it all comes down to your roof being strong and weather-resistant. If the material can be recycled at the end of its lifetime, then it becomes an even better choice.

2. Coatings

Avoid roofing materials that have harmful coatings, such as zinc and copper. These can wash down eventually with rain and prove toxic to the environment and the aquatic ecosystem.

3. Weight & Maintenance

Weight is an extremely important factor when deciding the choice of sustainable roofing materials as your house structure will have to support it effectively. Too heavy a roofing material can prove dangerous for the columns and walls of your house. Apart from this, heavier roofing materials are generally expensive to maintain. The durability of the roofing material is an important aspect of an efficient and eco-friendly roof.

4. Slope

The angle of the slope of your house’s roof plays an important role in deciding on the type of roofing material you wish to use. Some of these materials are for low-angled and flat roofs while others are better-suited for extremely sloped roofs.

5. Color & Reflectivity

The color of the roofing material is important according to the kind of weather in your region. If you live in a hot climate, then lighter-colored roofing material works best as it is able to reflect off most of the heat.

6. Aesthetics

An attractive roof certainly adds appeal to your beautiful home. Ensure that your choice of roofing material is not only durable and efficient but is also aesthetically pleasing.

7. Warranty

Having a warranty for the durability is a smart decision as re-roofing is certainly an expensive process. So be sure to choose the roofing material which is renowned for its durability.
