INSTRUCTIONS ON HOW TO DEAL WITH FACTORY ROOF LEAKS SAFELY AND EFFECTIVELY

1. The main cause of factory seepage and leakage

Factories, one of the important production bases, often face damage and leaking roofs. In fact, there are six common causes that most constructions encounter, negatively affecting production activities and labor safety.

The main causes of factory leaks can be listed as follows:

• Rust or loose screws: After a period of use, screws that are not properly maintained can rust or loosen, creating gaps for water to seep into the roof.
• Perforated roof: The impact of harsh weather such as heavy rain, strong winds and sunlight can weaken the roof and lead to perforation.
• Ineffective drainage system: Improper design or ineffective drainage system can lead to rainwater accumulation and corroding the roof.
• Mismatched joints: When building components are not installed or connected properly, gaps can be created that are susceptible to water infiltration and leakage.
• Structural gaps and lack of maintenance: Wall joints that are not regularly maintained can allow water to seep in, especially when the structure is not properly cared for.
• Lack of regular maintenance and repair: Failure to regularly inspect and maintain roofing panels can result in the loss of their leak-proof properties and make them susceptible to damage.

2. How to quickly identify a leaky factory?

To quickly detect leaks in the factory roof and make timely repairs, there are the following methods:

Direct observation with the naked eye:

• Carefully observe the condition of the factory roof.
• Pay attention to signs such as kinks, holes, dust or rust.
• Check the locations around the roof such as the roof edge, support structure, seams and intersections to detect loss of firmness.

Check periodically and when in doubt:

• Schedule regular inspections of the roof to detect early signs of leaks.
• Determine the inspection time based on the age and conditions of use of the roof.
• Check immediately if there are any unusual signs such as noise, vibration or change in the shape of the roof.

Check screws regularly:

• Make sure the screws on the roof are tight and not loose.
• Check the screws on the entire roof, especially in high load areas such as ridges, seams and intersections.
• Replace old, poor quality or damaged screws to ensure the strength of the roof.

Locate the exact location of the damage:

• Use measuring and inspection tools carefully to locate the damage on the roof.
• Make sure to accurately identify the damage location for correct and effective repair, minimizing unnecessary time and effort.
• Check for heavy rust spots:
• Look for and check for heavy rust spots on the roof surface.
