The Cause of Roof Water Overflow during Rain (And the Solution of Gutters)
Kerala’s lush greenery and beautiful architecture come with one major challenge heavy rainfall and high humidity. With over 3000 mm of annual rainfall and intense monsoons, homes in Kerala are constantly exposed to moisture.
One of the most common problems homeowners face is wall dampness, which not only affects aesthetics but also damages the structure over time. In this blog, we explore the top causes of wall dampness and how a proper rainwater management system like Besguard rainwater gutters can protect your home.
The number one cause of wall dampness in Kerala homes is poor rainwater management. During monsoons, rainwater flows directly from roofs onto walls and foundations.
Without a proper gutter system:
Water splashes onto exterior walls
Moisture seeps into the structure
Paint starts peeling and mold develops
A well-designed gutter system like Besguard ensures controlled water flow, protecting walls from constant exposure.
Traditional Kerala homes often have sloped tiled roofs, which channel large volumes of water quickly.
If gutters are missing or undersized:
Water overflows during heavy rain
Walls get continuously soaked
Structural weakening begins
High-capacity gutters (like Besguard’s advanced designs) are built to handle heavy monsoon downpours efficiently.
Small cracks may seem harmless, but in Kerala’s climate, they act as entry points for moisture.
Common causes:
Temperature changes
Poor construction quality
Aging buildings
Once water enters:
Damp patches appear inside walls
Paint bubbles and flakes
Mold growth increases
Many homes in Kerala lack proper external waterproof coatings, especially older buildings.
Without waterproofing:
Rainwater penetrates porous surfaces
Dampness spreads internally
Repairs become costly over time
Combining waterproofing with a gutter system provides double-layer protection.
Kerala’s coastal climate means constant humidity in the air, even without rain.
This leads to:
Condensation on walls
Persistent damp smell
Mold and fungus formation
While humidity cannot be avoided, proper drainage systems reduce excess moisture exposure significantly.
Internal water leakage is another hidden cause of damp walls.
Sources include:
Leaking pipes
Bathroom seepage
Poor drainage connections
These issues often go unnoticed until:
Damp patches spread
Walls weaken internally
In many areas, water accumulates around the building due to poor ground drainage.
This results in:
Rising dampness from the foundation
Water entering through lower walls
Long-term structural damage
Proper rainwater diversion systems help move water away from the building base, reducing this risk.
Kerala’s climate demands more than basic construction it requires smart water management solutions.
A high-quality gutter system like Besguard offers:
High water-carrying capacity to handle heavy rainfall
Rust-free uPVC material, ideal for coastal conditions
Leak-proof design that prevents wall damage
Aesthetic integration with modern and traditional homes
With over 30 years of expertise in rainwater management, Besguard systems are engineered to provide maximum protection and durability.
Wall dampness is not just a cosmetic issue it’s a warning sign of deeper structural problems. In a state like Kerala, where rain is intense and frequent, prevention is always better than repair.
Control rainwater at the source (roof)
Use high-quality gutter systems
Ensure proper drainage away from walls
Investing in a reliable solution like Besguard rainwater gutters helps you protect your home, enhance durability, and maintain long-term value.
Don’t wait for damp patches to appear.
Upgrade your home with a precision-engineered rainwater gutter system and stay protected all year round.
