The terrace is the most essential part of a building that covers the largest part of it and protects the building from vigorous atmospheric exposure. Its ignorance and lack of maintenance might lead to the leaky roof during monsoon. For old leaky roofs, it becomes compulsory for people to get in touch with the professionals dealing with terrace waterproofing. During the rainy season, the roof is the most affected part of the building which often leads to leakage that may cause severe dampness and spoils the entire decoration and interior of the building. So the efficient method to opt is to do the waterproofing solution for the terrace.

Make your roof stronger because if you are having a leaking roof, you will end up with the flood. In the previous blog, I have discussed all the basement waterproofing and the best waterproofing services in Delhi/NCR.

Steps for terrace waterproofing:-

  • Firstly, you need to clean all the dust from the terrace area.
  • Washing the roof/terrace properly.
  • Need to fill the visible cracks and honey-combing by repairing material.
  • For filling invisible cracks and small holes, apply the first coat with a diluted solution or perform injection grouting.
  • For strengthening the surface, apply multiple coats along with fiber mesh, if required.
  • Lastly, apply a final coat as protection for the rest of the waterproofing coats.

These above methods are very easy, safe, prolonged free, and worthwhile. So make sure that all the above steps must be followed by the constructionist.

These are some of the methods that are applied for terrace waterproofing. There may be many more techniques available which are used sometimes by the combination of any of these methods.




Now moving further, let’s come to know about types of roofs, their advantages, and disadvantages.

Types of roof:-

  1. Flat roofs.
  2. Slope/Pitched roofs
  3. Shells and Folded plates.
  1. Flat Roofs:- Flat roofs are having plane surfaces. All types of upper-story floors can serve as flat roofs. Flat roofs are used in plains where rainfall is less and climate is moderate. There should be minimum variation in pitch over the entire roof.

Advantage of having a flat roof-

  • The roof can be used as a terrace for playing and celebrating function.
  • They can  suit any shape of the building
  • Overhead water tanks and other services can be located easily.
  • They can be made fireproof easily as compared to a pitched roof.

The disadvantage of having a flat roof-

  • They cannot cover large column-free areas.
  • Leakage problems may occur due to the development of cracks and holes and lack of slope for easy movement of water.
  • Require proper treatment.
  • The initial cost of construction would be more.

2. Slope/Pitched Roofs:- Pitched roofs are used where rainfall is more. Sloping roofs are preferred in large spanned structures like workshops, factory buildings, and warehouses. The slope of the roof should be more than 10 degrees.

Advantage of having slope roof-

  • Water drains itself quickly, giving wind and gravity to push or pull water through the roofing materials.
  • Steep roofs can be covered with roofing materials that are fabricated and applied in small overlapping.

The disadvantage of having a sloping roof-

  • The top surface is in slope and hence advantage of the terrace is low.
  • It cannot cover a building of any horizontal direction because it becomes too tall on a broad building.

3. Shells and Folded plate:- These roofs are used to cover large column-free areas like auditoriums, factories, etc. Shell's roofs are like a curved surface.

Advantage of having Shells and Folded plate roof-

  • Material consumption is quite less.
  • A large column area can be covered.
  • Formwork can be removed easily.

The disadvantage of having Shells and Folded plate roof-

  • The top surface is covered and hence the advantage of the terrace is lost.
  • Formwork is costly.

Now, irrespective of the type of roof, it is very important to provide a proper waterproofing treatment at the proper time, preferably at the time of construction to protect the building, its’ interior, and the material stored from deterioration. Because if the water makes its’ way through the ceiling, the cost of treatment increases significantly and makes the roof comparatively weak.
