Flat Roof vs. Pitched Roof Designs: Which is Right for Your Home?

Is your new home planning already set in motion, and you can’t decide between a flat roof vs. a pitched roof? You want your home to be aesthetically pleasing and functional at the same time. But how do you decide which type of roof is best for your home?

Fundamentals of flat and pitched roof

A flat roof is commonly seen in commercial structures and modern house architecture. But in essence, they are not completely flat. They have a very slight slope that allows rain to run off into the gutters. 


Pitched roofs are made up of roof surfaces that slope down from the central ridge. They have an angle of more than 20 degrees and are common on
residential projects.

Taking a closer look at flat roof vs. pitched roof

With this deep dive into the crucial features of a flat and pitched roof, you can make an informed choice on what’s most suitable for your property.

Durability

  • Flat roofs: The life expectancy of flat roofs is between 10 to 15 years. Flat roofs do not drain as efficiently as pitched roofs, making them more prone to water pooling. If this constantly happens, water may seep into the seams, causing leakage problems and accelerating the deterioration of your roof.
     
  • Pitched roofs: Pitched roofs can last 30 to 50 years. Their triangular shape provides greater strength against winds and heavy rainfall. The pitched roofs' ability to dispel water and snow quickly is the key factor for their durability.

Installation

  • Flat roofs: If you are looking for a roof with a lower installation cost, this is for you. Flat roofs are easier to install, take up less space and use fewer materials. Additionally, it only takes much less time to install than a pitched roof, which accounts for its lower upfront investment.
     
  • Pitched roofs: The installation of pitched roofs requires more materials and labor; hence, a higher cost than flat roofs. Also, you need to check with your homeowner’s association or the local building official to see if a pitched roof is allowed in your area before installing one.

Insulation

  • Flat roofs: During the summer, flat roofs are particularly susceptible to heat because more surface area is exposed. They do not have space for air circulation, making them less energy efficient.
     
  • Pitched roofs: One of the biggest advantages of pitched roofs is their excellent thermal insulation. Triangular roofs provide better ventilation. They keep your home at a comfortable temperature during summer by eliminating hot air from the ceiling. They also expel cold and damp air during winter.

Guttering Needs and Drainage

  • Flat roofs: You have the option to put gutters on your flat roof. For this,  you'll need a slope on one side of the roof where the water can run into the gutters. They have to have proper gutters and downspouts installed to prevent water from pooling and forming puddles on your flat roof. Furthermore, they prevent leaks that may cause structural damage to your home.
     
  • Pitched roofs: For pitched roofs, rainwater is collected by gutters and carried to the ground in downspouts. You need regular maintenance to prevent dried leaves, dust, and other debris from clogging your gutters over time.

Maintenance Needs

  • Flat roofs:  Flat roofs are sensitive to temperature changes due to their structure. They require frequent maintenance services to prevent leaks and cracks. Experts recommend recoating flat roofs every 5 years to maintain their waterproofing abilities and lengthen their lifespan.
     
  • Pitched roofs: Pitched roofs require less regular maintenance. However, make sure to sweep or blow debris away from your gutters regularly to ensure they are free from twigs, leaves, and dust. Items that accumulate on your roof can cause various problems, such as allowing algae to grow, damaging shingles, or clogging your gutters.

Your roofs are designed to protect your property from sunshine, rainwater, snow, and strong winds. When choosing a roof for your residence, don't overlook the difference between a pitched roof and a flat roof.
