The roof of a factory isn’t just a cover. It’s the first line of defense against harsh weather, corrosion, and heat. The wrong roofing sheet can lead to water leaks, frequent repairs, higher energy bills, and, eventually, early roof replacement.
If you’re planning or upgrading a factory roof, here are some common mistakes you should avoid—and what to do instead.
1. Ignoring the Local Climate
One of the biggest mistakes is choosing roofing sheets without considering the local weather.
Coastal and Humid Regions
If your factory is near the coast or in high-humidity areas, corrosion can eat away at low-quality sheets within a few years. You need sheets with excellent anti-corrosion properties, such as color-coated sheets made from premium galvanized or galvalume coils.Hot and Dry Regions
In extremely hot areas, go for sheets with heat-reflective coatings to reduce indoor temperature and energy bills.Heavy Rainfall Areas
Thicker sheets with strong water drainage capacity are crucial to prevent leaks.
What to do instead
Always pick roofing sheets designed for your region’s climate. It saves you from frequent maintenance costs.
2. Choosing the Wrong Thickness
A lot of factory owners try to cut costs by selecting thinner sheets. But here’s the thing—thin sheets may look economical upfront, but they wear out quickly under industrial conditions.
For most industrial projects, 0.45 mm to 0.60 mm thickness is standard. Anything thinner compromises durability, especially for wide-span factory roofs.
What to do instead: Consult with a reliable manufacturer to pick the correct thickness based on your building size, span, and load requirements.
3. Overlooking Load-Bearing Capacity
Factories often house heavy equipment, and roofs need to withstand not just weather but also wind loads and, in some cases, the weight of maintenance workers or solar panels.
Using sheets without checking their load-bearing capacity can lead to sagging, structural damage, or even roof failure.
What to do instead: Ask your manufacturer for technical specifications, including the load-bearing capacity of the sheet profile you’re considering.
4. Ignoring Thermal and Acoustic Insulation
Factories can get uncomfortably hot, and noisy environments can affect worker productivity. Many project owners choose basic roofing sheets, only to regret not investing in better insulation later.
PUF Panels or insulated color-coated sheets are great for temperature-controlled factories.
Polycarbonate sheets can be used in selective areas to allow natural light without adding too much heat.
What to do instead: Think long-term. Spending a little more on insulated sheets now can significantly cut cooling costs later.
5. Focusing Only on Price
Price is important, but choosing the cheapest option often turns out to be the costliest mistake. Low-grade sheets corrode quickly, need frequent repairs, and might need replacement within a few years.
Remember, a roof is a long-term investment, not a short-term saving opportunity.
What to do instead: Balance cost with quality. Look for sheets made from premium coils (like JSW) that offer proven durability and come with a warranty.
6. Buying from Unreliable Suppliers
Some contractors source sheets from local traders or unknown suppliers to save money. The risk? Inconsistent quality, no after-sales support, and no warranty.
What to do instead: Always buy from a trusted manufacturer who can guide you on the right product, provide genuine materials, and supply all roofing accessories—purlins, fasteners, and ventilators—so your project runs smoothly.
