Many different factors determine the flat roof that works best for your commercial building. For example, is your building located in a sunny area? If it is, it may benefit from a TPO roof, which is white and reflects UV light extremely well. If your building is in a shaded area, an EPDM or built-up, modified bitumen roof may work better. If your roof receives a lot of foot traffic, a built-up roof provides a safe, walkable surface. Your roofing contractor can help you assess each factor and choose the right flat roof for your building.
