The majority of commercial buildings have flat or low-sloping roofs, whereas residential structures often have pitched roofs. This is because they are more cost-effective, faster to install, and may serve as equipment storage space. However, flat roofs are susceptible to more severe weather conditions, are more expensive to build, and require more upkeep. For this reason, it is essential to pick the appropriate roof covering for your building and company’s demands. Let’s look at the different types of commercial roofs in more detail.

Single ply commercial roofs

Single-ply systems are simple to install and durable. Single-ply membranes, which are often made from synthetic polymers, are available in a variety of thicknesses, colors, and materials that are lightweight, waterproof, and durable. They can also imitate materials that are more costly, such as metal.

When paired with insulation, single ply is thermally efficient and provides a flame-free, durable solution that is highly resistant to inclement weather. Membranes are a single, flexible sheet that can cover complex-shaped roofs well and are easier to install due to their ability to be welded using hot air. They are very adaptable and may serve as a base for other architectural elements such as roof terraces and balconies. They can also serve as the foundation for green roofs (see type 5), so contributing to the development of ecologically friendly roofing systems.

Metal commercial roofs

Metal roofs are lightweight, simple to install, and available in a variety of colors and finishes. They have a low pitch and are beneficial in circumstances where vandal-resistant roof finishes are essential. There are three types of metal roof cladding, sheeting, and tiling materials that may be tailored to complement neighboring roof styles.

Standing seam designs with elevated seams and concealed fasteners are adaptable, flexible, and excellent for curving roofs in particular. Prefabricated composite panels consisting of two connected metal skins provide a solution that is rapid and low-maintenance. Twin skins are similar, but they are constructed on-site and consist of two sheets of metal separated by a metal spacer grid. This permits a durability and longevity of up to 25 years. Metal roofs provide three robust options to meet a variety of architectural requirements.

Built up feeling systems

Built-up systems, often referred to as Reinforced Bituminous Membranes (RBM), employ felts with exceptionally high tensile strengths. They are flexible enough to expand and shrink well despite their strength. In addition, they have outstanding thermal values.

There are two techniques of building for RBM: hot and cold. The hot approach entails adhering the felt to the surface using a gas torch, whereas the cold method fixes the felt mechanically or adheres it with hot air and adhesives. Both have benefits. The hot process guarantees a rapid and durable solution, and the felt becomes an essential part of the surface. Without the use of gas torches, the cold approach is ideal for lighter jobs, especially where safety must be prioritized.

Liquid applied commercial roofs

These are types of commercial roofs that include a liquid-based polyurethane coating that forms a waterproof membrane with the substrate. Since it is administered cold, there are no hazards connected with heated labor, therefore it may be utilized in a variety of circumstances. It may be applied to a broad variety of material bases, from asphalt to steel, and offers several benefits. It is quick and simple to apply, seamless, durable and long-lasting, and requires minimal upkeep.

Liquid waterproofing is utilized not just for roofs, but also for basements, terraces, bridges, wet rooms, and many other applications; it is a good choice for complicated designs and challenging scenarios. It is an adaptable, highly elastic technology with great adhesion, UV resistance, and energy economy. Overall, a product with many advantages and uses.

Green roofs

Green roofs are prevalent owing to their numerous advantages and natural design options. They greatly benefit the environment by enhancing biodiversity and carbon sequestration, lowering pollution and the urban heat island effect, and constructing a roof with exceptional soundproofing and aesthetic qualities.

The benefits are numerous and varied, including enhanced water collection and reduced floods, less noise, improved air quality owing to the planting of vegetation, and an extended roof’s expected lifespan. In addition, the green roof design itself offers several other advantages. Roofs can be constructed and utilized for recreational reasons, such as seating and other facilities. Solar solutions may be included into designs, and they can be made to blend in with and compliment their surroundings for a more natural appearance. Green roofs have also been shown to improve our mental and physical health.
