Flat vs. Sloped Roofs: Which is a Better Option?

Flat vs. Sloped Roofs: Which is a Better Option?

A flat roof differs from a sloped roof in more ways than just appearance. Flat roofs are more cost-effective than sloped roofs and offer increased energy efficiency, as flat roofs have fewer seams that can allow air leakage. However, flat roofs require regular inspection and maintenance because they lack the pitch of a sloped roof, allowing water to roll off. Most flat roofs appear in commercial warehouses, but flat roofs are also commonly seen in architecture with a mid-century modern look.

What are the benefits of a flat roof?

Flat Roofs Are More Energy Efficient

When a home’s design allows for a flat roof, homeowners consider them more often now because they are more energy efficient. The Department of Energy classifies flat roofs as cool roofs with the most significant potential reflective surface area. Flat roofs are ideal for solar panels because the panels can be positioned to collect more direct sunlight than sloped roofs.

Flat Roofs Allow for Green Roofing

Flat roofs can also create an excellent environment for a “green roof” or rooftop garden. Energy efficient, green roofs provide shade and remove heat from the roof’s surface area and the surrounding air. The U.S. Environmental Protection Agency believes green roofs reduce heat islands, which are concentrations of heat that happen in metropolitan areas. No roof situation is perfect, and homeowners must consider that the living roots of plants can burrow into your roof, causing structural damage. Homeowners must thoroughly research plant selection for longevity and maintenance.

Flat Roofs = Lower Price

If roofing costs play a role in how a roof design choice is made, flat roofs come in significantly lower. This lower cost is due to the fact that flat roofs have less surface area, requiring less labor and materials. 


According to Angi, flat roofs cost between $3,100 and $10,000 to install or $4 to $13 per square foot. Sloped roof installation runs between $6,000 and $12,000. Costs will vary depending on the square footage of the roof and the materials you choose. Also, you need to consider the location of the home and the weather conditions.

The maintenance of a flat roof adds up over the life of the home. These additional costs offset the savings compared to installing a sloped roof. Homeowners must immediately handle any standing water accumulating on a flat roof during storms and snow. If not, it could leak into your home. Installed drainage slots on flat roofs help with water runoff, but the water has to be able to make it to those openings to be removed.

Need Outdoor Living Space?

Additional living space is available if you choose a flat roof. Depending on the construction materials, homeowners often use the space as a patio area. Rubber, plastic, and rubber foam are all acceptable options for laying the foundation to create an outdoor patio space. Thermoplastic polyolefin (TPO) is a rubber roofing material that reflects heat off flat roofs. 

Also, flat roofs are less forgiving to the movement of people. If homeowners consider a patio space to gather socially, guests may create a lot of noise for anyone inside their home. An effective way to reduce noise is to put a deck or lifted material on the roof to create separation. Appropriately selecting patio furniture is essential because it can easily puncture the roof and lead to leaks. Foot traffic can cause the roofing material to age more quickly, which is an added expense.

Flat Roofs Are Easy to Maintain

Although flat roofs require more maintenance and upkeep, it is simple. Flat roof maintenance is easy compared to sloped surface maintenance. They are also easier to inspect because they do not require tethered professionals or basket lifts.

The Modern Appeal of Flat Roofs

With their clean lines and minimalist appearance, flat roofs often appear on more contemporary-looking homes. If you’re looking for a modern look, a flat roof is your best choice.

Flat Roofs Are Better for Commercial Properties

Flat roofs are especially beneficial for commercial property owners since flat roofs are a more cost-effective option. Since flat roofs do not require the same amount of material and labor, they install faster, leading to lower installation costs. Additionally, flat roof repairs come at a lower cost, making flat roofing the best option for commercial property owners looking to save money.
