The Top Five Most Sustainable Materials for Your Roof

Nov 28

The shift to sustainability in society has had a significant impact on the roofing industry. can help you with your roof problems.

Below are five environmentally-friendly roofing options architects and developers might want to consider for future projects.

  • Clay

Clay tile is paradoxically one of the most environmentally-friendly roofing materials. It is made from clay from pits. Clay tile is durable and can be recycled easily.

Clay tiles made from two pieces have been in use for more than two thousand years. Two-piece clay tiles have been in production for over two thousand years.

Clay tile manufacturers are developing alternate layouts for clay tiles to allow for greater airflow under the tile. This regulates temperature and reduces cooling costs.

  • Concrete

Cement manufacturers have expanded their product lines to include roof tiles. The final product can be molded in three profiles: "s", "w", or "flat".

A concrete tile is attached to the roof with lugs and/or nails (small projections on either side of the tile that hold it in position against a wooden batten strip) The tile allows air to circulate beneath it because there is often a gap between the roof and it.

  • Slate

Slate can also serve as a natural product. Slate can last many years if it is properly installed.

Slate has existed for nearly a thousand years. Slate is easily cut to different thicknesses and widths.

  • Metal(s)

Metal roofs are a common feature of the past millennia. Lead poisoning has led to a large amount of lead being thrown out of the roofing industry.

Other metals are becoming more popular in roofing applications. These metals are also visually attractive.


  • Polyurethane Foam is a type of polyurethane.

Spray polyurethane foam is a great option for flat roofs. These two components are heated together and pressed together to form a solid surface. Foam can provide rigidity to structures, and it is lightweight and durable. It has been used in roofing for over 50 years.

It is seamless and easy to maintain. Most problems with foam roofs can be solved by a utility knife or tube of caulk.

Polyurethane foam can degrade over time when exposed to sunlight. Lighter colors will be more effective.

The process of applying polyurethane foam in a series is called "lifts". Polyurethane foam is applied in a series known as "lifts".

As society is more conscious about the environment, developers and architects are switching to greener roofing materials.
