If you own a large commercial building, and the roof is reaching the end of its lifespan, it is time to start planning what material you want your new roof made from. Choosing a new commercial roof should be based on price and function.
A built-up roof is often also referred to as a tar and gravel roof. It gets its name from the process of applying multiple layers of tar and supporting fabrics to a roof to create a waterproof base, with the application of a layer of gravel over the top of the roof. It is easy to take care of and provides excellent waterproof protection. A built-up roof is typically used on commercial buildings with flat roofs.
Spray Polyurethane Foam
Spray polyurethane foam is great if you don't want to tear off your old roof but you want to use a new roofing material. You can easily spray the material on top of older roofing material, reducing labor and waste.
Spray polyurethane foam helps create a great waterproof barrier on your roof that is friendly to the environment. This material is excellent at helping to improve the energy efficiency of your commercial building. This type of spray foam is most often used on flat roofs but can be used on roofs with a slight slope.
A single-ply membrane is a great, affordable choice. As the entire roof is applied in a single layer, it is really easy to install and easy to take care of. The material is lightweight and will not add a lot of weight to your building. It is designed to reflect light away and can help keep your building cool if your commercial property is located in a warmer area. It can be used on both flat and sloped roofs.
Finally, there is metal roofing. Metal roofs usually work best on a building with a slightly sloped roof. Metal roofs are popular because they are long-lasting. You can get decades of usage from a commercial metal roof. You can also choose from an array of colors and styles, allowing for an improved curb appeal. Additionally, a commercial metal roof can help protect your building from fires and is highly energy efficient.
When choosing the right material for your commercial roof, you need to consider the shape of your roof, the material's sustainability, the cost of the material, and how long it will last. Reach out to a roofing professional to learn more.
