Flat roofing is popular in commercial buildings because it offers a combination of affordability and practicality. Flat roofs are relatively easy and inexpensive to construct, making them a great choice for businesses. Flat roofs also offer greater usable space compared to pitched roofs, so they are ideal for businesses that need to maximise the use of their roof area. Additionally, flat roofs tend to be strong and durable, standing up well against the elements while providing excellent insulation properties.
