What Are The 3 Main Types Of Roofs?

Imagine you are building your dream home. As you navigate through the planning process, one key decision to consider is the type of roof that will best suit your needs. With so many options available, it can be overwhelming to determine which roof is right for you. In this article, we will explore the three main types of roofs: pitched roofs, flat roofs, and mansard roofs. Each type has its own unique characteristics and benefits. So, let’s dive in and discover which roof will provide the perfect finishing touch to your home.

Flat Roofs

Definition and Characteristics

Flat roofs, as the name suggests, are roofs that have a minimal slope or no slope at all. They are generally horizontal and have a sleek, modern appearance. The main characteristic of flat roofs is their minimal pitch, which allows for efficient use of space and easy roof access.


One of the main advantages of flat roofs is their affordability. Compared to other roof types, flat roofs require fewer materials and are easier to construct, which can result in cost savings. Additionally, the lack of slope makes flat roofs easier to maintain and inspect, as there are no hard-to-reach areas. Their minimalistic design also allows for additional usable space, such as rooftop gardens or solar panel installations.


However, flat roofs are not without their drawbacks. The main disadvantage of flat roofs is their susceptibility to water pooling and leakage. Without a sufficient slope, water may accumulate on the surface, leading to potential damage and leaks. Regular maintenance and frequent inspections are necessary to prevent these issues. Additionally, the lack of slope also means that flat roofs are less efficient in shedding snow and debris, which may require manual clearing during periods of heavy precipitation.

Popular Materials for Flat Roofs

Some commonly used materials for flat roofs include:

  • Built-up Roofing (BUR): Composed of multiple layers of tar and gravel, BUR provides excellent durability and waterproofing.
  • Modified Bitumen: Made from asphalt and reinforced with fiberglass or polyester, modified bitumen is known for its strength and flexibility.
  • EPDM: Ethylene Propylene Diene Monomer (EPDM) is a synthetic rubber membrane that offers excellent weather resistance and durability.
  • PVC: Polyvinyl Chloride (PVC) is a popular choice for flat roofs due to its lightweight nature and UV resistance.
  • TPO: Thermoplastic Olefin (TPO) is a single-ply roofing material known for its energy efficiency and strong resistance to UV rays.

Pitched Roofs

Definition and Characteristics

Pitched roofs, also referred to as sloped or angled roofs, are roofs with a noticeable slope or pitch. They are commonly seen in residential buildings and have a classic, traditional appearance. The angle of the slope can vary, depending on the architectural style and climate of the region.


Pitched roofs offer several advantages. First and foremost, their sloped design allows for effective water drainage, preventing the accumulation of water and reducing the risk of leaks. The steep slope also facilitates easier removal of snow, leaves, and debris, minimizing potential structural damage. Pitched roofs are also known for their durability and longevity, as they can withstand various weather conditions and are less prone to damage caused by wind.


Despite their many advantages, pitched roofs have a few disadvantages to consider. The main drawback of pitched roofs is their higher cost compared to flat roofs. The construction process is more intricate, requiring additional materials and specialized techniques. The steep slope can also limit the usable space in attics or loft areas. Additionally, maintenance and repairs on pitched roofs may be more challenging due to the height and angle of the structure.

Popular Materials for Pitched Roofs

Some commonly used materials for pitched roofs include:

  • Asphalt Shingles: One of the most widely used roofing materials, asphalt shingles offer affordability, versatility, and a wide range of color options.
  • Metal Roofing: Metal roofs are known for their longevity and durability. They can withstand extreme weather conditions and provide excellent energy efficiency.
  • Clay or Concrete Tiles: These materials are popular for their aesthetic appeal and ability to enhance the architectural style of a building. They are also durable and resistant to fire and pests.
  • Wood Shingles or Shakes: Wood roofing materials are renowned for their natural beauty and charm. They add warmth and character to a home but require regular maintenance to prevent rot and decay.
  • Slate: Slate roofs are known for their elegance and longevity. They have a distinctive appearance and can last for over a century with proper care and maintenance.

Shed Roofs

Definition and Characteristics

Shed roofs, also known as mono-pitch roofs, are roofs that have a single sloping surface. They are commonly found on sheds, garages, and modern architectural designs. Shed roofs have a simple and streamlined appearance that complements contemporary aesthetics.


The simplicity of shed roofs is one of their key advantages. They are easy to design, construct, and maintain. The single slope allows for efficient water drainage, reducing the risk of leaks and water damage. Shed roofs are also a cost-effective option, as they require fewer materials and labor compared to more complex roof designs.


Despite their simplicity, shed roofs have a few limitations. One of the main disadvantages is reduced attic or storage space due to the slope of the roof. This can limit the usability of the upper levels of a building. Additionally, the asymmetrical design of shed roofs may not be suitable for certain architectural styles or climates, where a more balanced aesthetic is desired.

Popular Materials for Shed Roofs

Some commonly used materials for shed roofs include:

  • Metal Sheets or Panels: Metal roofing is a popular choice for shed roofs due to its durability, low maintenance requirements, and cost-effectiveness. It is available in various colors and finishes.
  • Bitumen Sheets: Bitumen roofing offers excellent waterproofing and durability. It is easy to install and provides reliable protection against the elements.
  • Corrugated Fiberglass: Fiberglass panels with corrugated profiles are lightweight, durable, and resistant to UV radiation. They are an affordable option for shed roofs.
  • Polycarbonate Sheets: These translucent sheets are lightweight, impact-resistant, and provide good UV protection. They allow natural light to enter the shed while offering robust weatherproofing.

Remember, choosing the right roofing style depends on various factors, such as the climate, architectural style, budget, and personal preferences. Consult with a professional roofer or architect to determine the most suitable roofing option for your needs.
