Flat Roofs or Terrace Roofs
A flat roof is the most common roof category. Despite its simple design, its appearance is pleasing to the sight and you can use it for various purposes. Flat roofs have a shallow slope that helps rainwater to flow easily to the gutter. However, if the slope is too shallow, you may experience ponding. Below are the types of flat roofs:
- Composite Roof: It’s made of bricks and other materials like concrete, brickbat, and teak wood joist.
- Jack Arch Roof: It helps to resist vibrations and shocks. However, it requires hard labor.
- RCC Roof or Reinforced Brick Slab Roof: It’s mostly used in residential buildings. It has a long lifespan.
- Mud Terrace Roof: It’s made of white earth mud with a high percentage of sodium salt. This is ideal for areas that experience little to no rainfall. It helps to keep the house cool by providing insulation against heat.
- Precast Concrete Roof: It’s popular in new homes. It requires less labor and helps to save time.
Benefits of Flat Roofs

Pitched or Sloping Roof
A pitched roof slopes downward in one or more parts. Sometimes, it slopes from edge to edge in one part. It can also slope at an angle from the peak of the roof. They were formerly made with timber, however, you can now find pitched roofs made of concrete. Pitched roofs are a great choice for both modern and traditional buildings.
Types of Pitched Roofs
- Mono-pitch roof
The mono-pitch roof is ideal for storehouses or garages. It’s also ideal for locations with heavy rainfall as it has a slope of over 45⁰. It’s usually a standalone sloping roof surface and doesn’t attach to any other roof surface.
- Double-pitch roof
This roof type has two sloping surfaces. It’s mostly found in residential homes because it’s economical.
- Slant roof
Slant roofs are also called gable roofs. They’re made of different materials like asphalt, tiles, shakes, or metallic shingles. Slant roofs provide great ventilation and it’s simple to build.

Shell Roofs or Curved Roofs
Shell roofs are modifications of pitched roofs. They’re known for their ability to cover large buildings. They function both as a structure and also a covering. Shell roofs are made of concrete panels. These panels are either curved spherically or cylindrically for better durability. They are also built of other materials like glass, hardboard, lattice, ceramics, plastics, and steel sheets. Shell roofs are ideal for open buildings without walls or pillars that can support pitched or flat roofs.
Below are the three types of shell roofs:
- Continuous barrel shells: They’re used in large buildings that need multiple shells for the floor space.
