Flat Roofs for Homes

When considering building construction or roof replacement projects, you might find yourself wondering what type of roof you want. Namely, you can choose between a flat roof and a sloped or pitched roof. But what exactly does it mean to have a flat roof? Does such a roof have any specific advantages or disadvantages compared to a pitched roof? We’re here to give you the answer.

How Do Flat Roofs Differ from Pitched Roofs?

A flat roof simply describes a roof that is level. More accurately, it is almost level. Most flat roofs still have a minor slope to prevent rainwater from collecting on top. The majority of commercial buildings tend to have flat roofs.

On the other hand, pitched roofs have a notable slope to them and usually have a triangular shape. The purpose of this slope, of course, is the same as for flat roofs. The majority of residential homes tend to have pitched roofs.

Advantages of Flat Roofs

Installation Cost

Compared to pitched roofs, flat roofs cost much less to install. They have a relatively simple structure and require fewer materials. As a result, the installation process takes less time overall, which is a significant advantage in case a building has to be ready as soon as possible.

Additional Space

A flat roof means you have space on top of your roof, which can be used in a variety of ways. A good example for commercial buildings is to build a relaxation area on top of the roof, where employees can go for some fresh air during break time. Other options include placing commercial HVAC units on top of the roof or even installing solar panels.

Disadvantages of Flat Roofs

Drainage Problems

Unfortunately, flat roofs just aren’t as good at dealing with rain and snow. Despite the minor slope that they are most often designed with, too much rainfall can still easily result in water puddles on the roof. When that happens, the water cannot drain anywhere and won’t simply evaporate either. Thus, it will slowly damage the roof until it eventually results in a leak.

More Maintenance

Flat roofs can get damaged more easily than pitched roofs, especially in areas where lots of rainfall and snow are common. This is primarily due to the issue mentioned above. After heavy rainfall, hiring a reputable roofing company to inspect the roof is of utmost importance. They will make sure that there is no damage and patch it up if needed.

Conclusion

As this article has hopefully made clear, flat roofs come with a number of unique advantages and disadvantages. They cost less to install and provide additional space, but commonly have problems with rainfall and require more maintenance overall. In the end, whether to choose a pitched roof or a flat roof is entirely a question of preference.
