Flat Roof vs. Sloped Roof – What’s the Difference

Apr 12, 2022

A new roof is a big commitment. It’s a costly renovation that you’ll be living with for at least a couple of decades.

When homeowners commit to a roof replacement project, one of the biggest decisions they have to make is choosing the roofing material. However, many forget that the shape of the roof is just as important to consider.

While both sloped roofs and flat roofs have several benefits, they each come with their implications as well. Durability, cost, and energy efficiency are all important factors to consider when comparing a flat roof vs sloped roof.

Need help deciding between a flat roof vs sloped roof? Here’s what you need to know to make the right choice for your home.

Flat Roofs & Their Benefits

Flat Roofs & Their Benefits

A flat roof is exactly as it sounds like, flat. This roofing style is most commonly found on industrial and commercial buildings, although they are also suitable for residential properties.

Many homeowners are wary of choosing a flat roof for their home. They’re concerned that precipitation will have nowhere to go and will just puddle on the roof. Though it’s not noticeable, flat roofs are actually designed with a slight, almost undetectable slope that’ll lead water into the gutters.

One of the biggest appeals of flat roofs is that they don’t cut into the interior space. Homes with sloped roofs often have the upstairs rooms tucked under sloped ceilings. With flat roofing, homeowners can enjoy the additional space upstairs which is perfect for tall furniture and large equipment.

Flat roofs are also more energy-efficient since they have a membrane-like structure that allows for better insulation. The additional insulation helps prevent heat loss during the winter and keeps cool air inside during the summer season.

How Do Sloped Roofs Differ?

Sloped roofs can be split into two categories: steep slope and low slope roofing.

For a roof to be classified as a steep roof, it must have a pitch of 18 degrees or larger. Whereas a low-slope roof would have a pitch measuring under 18 degrees. Sloped roofs are most commonly seen on residential properties, as the triangular shape gives the classic “homey” aesthetic.

This type of roof is typically constructed in two separate parts and then joined at a ridge in the center of your house. Both halves of the roof slope at a slight angle, allowing any precipitation to trickle down and into the gutters.

In terms of longevity and maintenance, sloped roofs generally last longer than flat roofs and require less maintenance – thanks to their ability to minimize leaks.

While both types of roofs require regular maintenance, sloped roofs don’t collect water as easily as flat roofs do, making them less susceptible to water damage. However, they do tend to be more costly as the build is more complex and requires more materials.
