This combination provides a durable and weather-resistant surface that can protect the building from the elements.

These tiles get shaped and colored to resemble natural materials such as slate or wood, adding a unique aesthetic appeal to any building. Tile roofing is fire resistant, which makes it a popular choice for areas with a high risk of wildfire.

Green roofing is a type of roofing that involves the installation of a layer of vegetation on a flat or sloped roof. It helps reduce energy costs and reduction of the urban heat island effect. Green roofs also help with stormwater management by slowing down, retaining, and filtering rainwater, reducing the load on the city’s drainage systems.
