The Cause of Roof Water Overflow during Rain (And the Solution of Gutters)

Rain is part and parcel of Indian life, particularly in such states as Kerala. Although rain is beneficial and it causes greenery, it may also destroy your building silently when rainwater is not handled well.

Roof water overflow is among the most frequent issues that homeowners and builders have to deal with. You might have noticed water overflowing along sides, down the walls, or puddles along the foundation. But why does this occur?

We have to deconstruct it and of more practical importance, how the right gutter system can make it right.

What Is the Cause of Roof Water Overflow?

1. There is no gutter system there

India has many buildings that are built without a proper drainage system of rainwater. The heavy rainfall when hitting the roof can no longer find a way out, thus spilling at edges.

This leads to:

  • Wall dampness
  • Paint damage
  • Foundation weakening

2. Low Water Carrying Capacity

Not every gutter is created to cope with heavy rainfall. In heavy monsoons, small or poorly built gutters are overflown by the fact that they cannot handle huge amounts of water.

Modern systems such as Besguard are designed with high water carrying capacity to withstand even the extreme rainfall conditions.

3. Poor Design & Installation

Old or conventional gutter designs are usually placed too far away at the roof edge, thus, the water fails to take the gutter route and overflows.

Conversely, the sophisticated designs are also nearer to the building minimizing the spillovers and allowing the flow to be smooth.

4. Blockages & Debris

Gutters and down pipes may be blocked by:

  • Leaves
  • Dust
  • Debris

When a flow of water is hindered, it is soon accumulated and overflowed.

5. Poor Materials & Structural Problems

The cheap materials may:

  • Bend
  • Crack
  • Sag

under the pressure of heavy rain. This interferes with the flow of water causing leakage and overflow.

Good-quality uPVC systems are made to resist adverse weather conditions and also remain stable as time goes by.

What then happens when water overflows?

Neglecting water overflow in roofs may also result in severe long-term consequences:

  • Structural cracks in walls
  • Leakage of water in rooms
  • Growth of molds and fungus
  • Near foundation soil erosion
  • Reduced building lifespan

In other words, uncontrolled rain water may ruin your investment gradually.

The Solution to the Problem by Gutters

A well planned rainwater gutter system is not an accessory, it is a necessity to keep your building safe.

1. Controlled Water Flow

The rainwater falling on the roof is collected by gutters, and it is directed through down pipes thus avoiding uncontrolled overflow of the rainwater.

2. High-Capacity Drainage

The contemporary systems are constructed with the capacity to manage high amounts of water. As an illustration, Besguard gutters are set to work faster and have greater capacity even during heavy rain.

3. Leak-Free Design

High-technology guttering involves precision engineering to allow water to flow effectively with no leakages or spillages.

4. Structural Protection

Gutters keep walls and foundations dry, eliminating long-term structural damage and lowering maintenance expenses.

5. Aesthetic Integration

The modern gutter systems are not clumsy and unappealing. The designs of Besguard are made to combine with the contemporary architectural designs, which improves the appearance of the building.

Why Choose Besguard?

In the case of keeping your building out of the reach of rainwater, the difference is in the selection of appropriate systems.

Besguard is unique due to:

  • More than 30 years of experience in production and construction
  • Large capacity uPVC rain gutters
  • Creative designs to prevent overflow and leakages
  • Durable, weather-resistant materials
  • Long-term reliability and easy installation

Besguard guarantees that your building is safe, be it at home or in a business establishment, even in the monsoons.

Final Thoughts

The overflowing of roof water is not a seasonal problem, it is a structural hazard. The reality is plain and straightforward:

Unless water is directed, it will cause destruction.

A good installation of a rain water gutter system is one of the best things you can invest in your structure.

Using solutions such as Besguard, you do not only stop rainwater, but you secure your whole structure.
