3 Reasons Flat Roofs the Best for Commercial Buildings

Have you ever wondered why commercial establishments aren’t too keen on experimenting with their building’s roofing systems? Oftentimes, this is a case of ‘don’t fix what isn’t broken,’ which is what many businesses follow when designing their property’s architecture. Flat roofs offer the functionality and sustainability that has remained unrivalled to this day.

Flat roofs for commercial buildings

Although many companies use different aesthetic improvements to make their properties stand out, the structure of their buildings generally remains the same. No matter how colourful their banners and signages are, they are still connected to the rigid structure of a flat roof building.

In this article, we will share three reasons flat roofs are the best option for your commercial property:

1. Durability with different material options

Although flat roofs are more expensive in contrast to sloped roofs, they deliver a substantial return on investment for its value. A flat roof’s durability can last for over three decades, which is a considerable length for an owner who’s looking to maintain their business for the long term. As a result, you will not have to change your roof every few years or opt for repair services that will cost more over time.

In terms of installation, your labour costs will be much cheaper since you won’t have to apply reinforcements to maintain its structure. You can also choose from a wide selection of materials for your roof’s flooring. A popular choice for commercial buildings is asphalt because of its long shelf life. The next best contender is an EPDM membrane system, which requires only biannual maintenance to last for just as long as asphalt.

2. Variability in installing roof extensions

As any property owner would tell, making the most out of your limited spaces is a necessary step in maximizing your real estate. Your roofing has to accommodate for various extensions that are necessary for your business to optimize the space of the commercial building.

Some essential roof attachments include HVAC unit placements, roof storage placements, and even roof gardens for hotels and inns. Flat roofs allow you to convert these spaces depending on your business’ needs to have the highest profitability from your building’s layout and structure.

3. Sustainability and ease-of-access

A flat roof’s drainage system is easily adaptable to eco-friendly water solutions that recycle rainwater or snow runoff. The collected water can be integrated into the roof’s structure and used for gardening reserves or for water fountains. Some buildings also use reverse osmosis installations to turn the recycled water into viable alternatives to running water on the tap.

Sustainability is another factor that highlights a flat roof’s advantage. Because of its natural design, it can be easily accessed and maintained without needing costly security measures in place. This significantly reduces your roof cleaning service expenditure due to its ease-of-access compared to sloped roofing systems.


There’s a reason flat roofs are the industry standard for commercial and industrial establishments. This is because they expand a property’s functionality while providing an easy-to-maintain roofing system to deal with various issues, such as harsh weathering conditions and occasional roof repairs and replacements.
