Binh Duong, August 8, 2025 – This year’s rainy season is entering its peak, causing many factories in industrial parks across Binh Duong, Dong Nai, Ho Chi Minh City, and other areas to suffer from severe roof leaks. These leaks are directly affecting production and goods storage. Construction experts recommend that businesses repair factory roofs promptly to prevent damage to machinery, raw materials, and to minimize the risk of operational disruption.
Field observations reveal that many factories built between 5 to 15 years ago are showing signs of deterioration. Among these, the roof is the most affected component as it is constantly exposed to sunlight, rain, wind, and the harsh industrial environment.
Common causes of roof leaks include:
Roofing sheets rusting due to oxidation and humid conditions.
Loose screws or worn-out rubber washers, creating gaps for rainwater to seep in.
Loose panel joints caused by peeling or degraded sealing materials.
Roof structure deformation due to storms or excessive load.
Poor initial construction quality without long-term leak prevention measures.
"Just a few small leaks can, after a heavy rain, leave the entire production area wet, forcing machines to halt for cleanup. The cost of production downtime is often far greater than the cost of timely repairs."
Failing to address roof leaks promptly can lead to serious consequences:
Damage to goods and raw materials – especially moisture-sensitive items such as paper, wood, food, and electronic components.
Safety hazards for workers – slippery factory floors increase the risk of workplace accidents.
Damage to machinery and equipment – water seeping into control panels, motors, or wiring can cause electrical short circuits or fires.
Higher maintenance and replacement costs – repair expenses may be 3–5 times higher if issues are left untreated.
Loss of reputation with clients – delayed orders caused by production interruptions.
Industrial construction experts emphasize that the cost of repairing the damage caused by leaks is often many times higher than the cost of repairing the roof at the first sign of trouble.
Depending on the severity of the damage, businesses can choose one of the following solutions:
When to apply: When the roofing sheets are severely degraded, with rust covering more than 50% of the surface.
Advantages: New roof lifespan of 15–20 years, high aesthetic value, and excellent leak resistance.
Disadvantages: High cost and longer construction time.
When to apply: When only certain areas of the roof are damaged.
Advantages: Cost savings, quick installation.
Disadvantages: Lower overall uniformity and aesthetics.
When to apply: When leaks originate from panel joints or screw positions.
Solution: Apply specialized silicone or PU waterproof sealants, replace screws with new ones featuring rubber washers.
When to apply: When the roof is still in good condition but needs improved leak resistance and temperature control.
Advantages: Extends roof lifespan, reduces indoor factory temperature by 4–7°C.
A reputable factory roof repair contractor typically follows these five steps:
Inspection – Assess the entire roof, identify leak points and causes.
Propose a Solution – Recommend the most cost-effective and time-efficient approach.
Prepare Materials and Equipment – Roofing sheets, screws, sealants, scaffolding, and safety gear.
Execution – Carry out repairs according to technical standards and workplace safety regulations.
Warranty and Maintenance – Provide warranty from 12 to 36 months depending on the work scope.
While many companies offer factory roof repair services, businesses should select contractors who:
Have proven experience in large industrial park projects.
Use genuine, certified waterproofing materials.
Employ skilled and safety-conscious technicians.
Provide clear contracts and long-term warranties.
"A factory roof repaired with proper techniques not only stops leaks but can also extend the building’s lifespan by decades."
To minimize the recurrence of roof leaks, businesses should:
Inspect the roof every 6–12 months.
Clean gutters to prevent clogging and overflow.
Replace rubber washers and screws when signs of aging appear.
Apply anti-rust coatings to protect the roofing sheets.
Repairing a leaking factory roof is not only about maintaining the building—it is also a crucial step in protecting production operations, assets, and a company’s reputation. With the rainy season becoming increasingly unpredictable, taking timely action will help factory owners reduce losses, maintain stable operations, and ensure worker safety.
The factory is the heart of every manufacturing enterprise. Over time, the factory inevitably deteriorates and breaks down, directly affecting productivity and labor safety. Therefore, factory repair services in industrial parks are increasingly gaining attention and becoming an important factor in the production infrastructure maintenance plan.
In the context of increasingly fierce competition in production, ensuring that the factory system always operates stably, safely and meets technical standards is a vital factor for every business. In large industrial parks such as VSIP, My Phuoc, Tan Dong Hiep, AMATA, ... factories often face damage and deterioration due to continuous production processes. Professional factory repair services are an urgent solution to help businesses maintain stability and sustainable development.
