Flat roofs in residential buildings are now trending as homeowners seek modern design, extra rooftop space, and cost savings. Low‑slope flat roofs blend style with function.

To note, all roofs must have a slope to allow for water drainage off the roof. The name “flat roof” gained popularity in the roofing industry to distinguish low slopped roofs from pitched roofs. Flat or low-sloped roofs must have a watertight waterproofing membrane to prevent leaks and ensure long-term protection.

Why are flat roofs gaining popularity in residential buildings?

We spoke to our clients, and here are some of the reasons why they chose flat roofs over pitched roofs:

Better Utilization of Space

Land is a scarce resource; most scarce resources are also expensive. When your residential building has a flat roof, waterproofing allows you to transform the rooftop into usable space. It becomes ideal for house parties, a swimming pool, or any family activity that requires extra space. Fixing interlocking blocks after waterproofing ensures safety and comfort while maximizing your rooftop’s functionality.

Flat Roofs are More Efficient to Install

All flat roofs must be waterproofed. Building consultants and roofing contractors usually specify waterproofing membranes or liquid waterproofing solutions for waterproofing flat roofs.

Liquid waterproofing solutions use a roller for fast application and finish quicker than traditional pitched roof installations. Waterproofing membranes, on the other hand, come in standard sizes and require a blow torch method to apply, which is also quite fast.

The ease of installation translates into savings for the homeowner both in time and resources.

Flat Roofs are Easy to Maintain

All roofs require maintenance to check if there is any debris that might clog up the gutters or downpipes, or to identify any wear and tear issues in good time.

Flat roofs are easier to access, and thus, maintenance surveys are easier to conduct. Your roofing expert/contractor can easily walk on flat roofs for maintenance without fear of breaking roofing tiles/shingles, falling off the roof, or suffering injuries.

Flat Roofs have Great Weather Impact Resistance

Flat roofs are made of concrete and sealed with quality waterproofing membranes and therefore are not prone to damage by strong winds or rainfall. They can withstand adverse weather conditions, unlike pitched roofs, where it is not unusual to see some tiles lifted in severe weather impacts.

You can Incorporate a Green Roof on Flat Roofs

Our environment is continuously under attack. A lot of effort to save the environment is being advocated for which starts from the home level. To do your part in reducing the “concrete jungle” tag and help save the environment, a section of your flat roof can be set aside for a green roof using the Antiroot Waterproofing Membrane. This will of great benefit for the owners in terms of beautiful spaces, cleaner air, and an improved drainage system.

Conclusion

If you are considering building a flat roof for your next residential roofing project, ensure that you check with your local building code if flat roofs are allowed. Some gated communities give strict guidelines on the roof design that will be approved.

We strongly recommend using a professional roofing contractor to install, repair, maintain, and inspect your roof.
