Flat Roofs: The Good And The Bad

There are many reasons to consider a flat roof for your next construction project. Flat roofs are easier to maintain and are durable. They can last longer than traditional sloping roofs, making them a good option for businesses and other institutions that need a roof that will stand up to wear and tear. Despite their benefits, there are some drawbacks to flat roofs that you should know before deciding. At TC Roofing & Restorations, we want our clients to know the good and bad of flat roofs so they can determine whether they are suitable for you.

Pros of Flat Roofs:

Lower construction and repair expenses:

Flat roofs require less roofing material since they take up less area than sloping roofs. This reduces the original construction cost while saving money if substantial repairs are needed.


If longevity is important to you, a flat roof is the right choice. Because a flat roof is water-resistant, you won’t have to worry about water damage. A concrete roof is a robust roofing system that can withstand powerful winds. There is less possibility of fallout when choosing a flat roof for your home.


The flat roofs of homes are often overlooked but can be an excellent place for gardeners. These durable surfaces offer plenty to work with, including perfect growing conditions. A flat roof may be used to provide a stunning feature to a home while also providing additional weather protection.

A good location for air conditioning units:

Commercial HVAC systems are frequently installed on flat rooftops. Having your HVAC system on the roof rather than on the ground increases security and protects it from harm.

Our roofing professionals should verify the substructure to validate the roof capacity before installing the units. Low areas and puddling will occur if contractors do not correctly install them. All of these things result in leaks.

Cons of Flat Roofs:

Lack of drainage:

It is the most significant drawback of a flat roof, so it is necessary to inspect your roof regularly. Your drains may become clogged with snow and water if you do not periodically examine them. Clean up the drains as needed, and use a waterproof seal to avoid leaks. Remember, there are no slopes down which the water or snow may flow.

Early replacement:

With good maintenance, most sloping roofs may last 20 years or longer, but flat roofs need to be rebuilt every ten years.

Mostly Flat roofs use cheap roofing materials like TPO, EPDM, rubber, and bitumen, but they only last for 10 to 15 years.

Concerns about green roofs:

While converting a flat roof into a garden space is both environmentally and aesthetically beneficial, invasive plant roots can cause difficulties over time. The plants might penetrate the roof and cause leaks if not properly treated.


Every house buyer and builder has a vision for their ideal home, and a flat roof may be the best option for you. Although flat roofs take more maintenance and perform better in warmer regions, anybody can have a practical, attractive flat roof with the appropriate builder.
