If building a new commercial property or renovating your existing building, you may be replacing its roof or choosing a new one. Many businesses and organisations decide flat roofs are the best choice, and you have probably noticed them throughout towns and cities close to where you live, whether its office blocks or retail premises rather than the pitched roofs we’re used to seeing with residential houses. But what are the benefits of flat roofing for commercial properties?

Why do commercial buildings have flat roofs? Discover the benefits of flat roofing for commercial properties, including space, access, materials & cost. Find out how businesses choose cost effective roofing solutions.More Space

Flat roofing in large commercial builds creates more space both internally and externally. In houses with pitched roofs, the top floor (i.e. the attic or loft) often has reduced headroom, so keeping a flat roof on top of the building ensures the upper level can be used like any of the other floors. Many businesses or landlords use the extra space on top of the building wisely too (e.g. for mechanical equipment), maximising the square footage. In fact, in many types of large multi-storey building, the roof is even used as a car park.

Easy Access

While expert roofers can repair any type of roof, in larger commercial buildings, having a flat roof can make maintenance and repair work easier. One downside of a flat roof is that water can pool there rather than the run-off produced by pitched roofs, so you may need to be aware of snow removal techniques and safety when temperatures drop to freezing levels. It’s not hard for flat roofs to become an ice rink in the winter. That said, it’s easier to inspect the roof for damage both before and after extreme weather, keeping on top of repair work.

Cost Effective

Commercial properties are often much larger than houses, especially if the building houses several company offices, shops and restaurants. A sloped roof isn’t the best solution either structurally or financially, with flat roofs being a more cost effective choice for larger buildings. However you’ll need to implement a good water drainage system into the design, so this will need to be factored into the costs.

High Quality Materials

There’s a misconception that while pitched roofing often involves strong and robust tiles or slates, flat roofing is made from poor quality felt which rips and deteriorates over time. However, flat roofing techniques and materials have come a long way, with more durable and watertight options now available to help protect your building. This includes RubberBond FleecebackTM EDPM, liquid roofing and fibreglass flat roofing. If you still want a traditional material such as lead or bitumen felt, a reputable roofer who offers specialist flat roofing services can talk you through the advantages and disadvantages of each. Your final decision may depend on your commercial roofing needs, budget and the intended use of the roof.
