Common Mistakes to Avoid When Buying Sandwich Roofing Sheets
Choosing Panels Based on the Cheapest Price
Cheaper roofing panels will have less dense insulation and/or thinner sheets.
Failure to Take Note of the Density of Insulation PUF
Check density of PUF (polyurethane foam) and panel specifications instead of relying only on the thickness stated by the supplier
Using Thin Sheets for Industrial Buildings
Industrial buildings require higher-thickness metal sheets for the roof since the wind exerts a lot of pressure and, over time, can cause stress on the roof panels.
Not Professional Installation May Lead to Leaks and Thermal Bridging
Even the best roofing sheets can become useless if the installation is done unprofessionally. Poor installation can cause roof leakage or thermal bridging, which affects the roof panel efficiency

Before purchasing, ask yourself,
- what the building will be used for,

- whether it is located in a rainy or coastal region,
- how long the roof is expected to last
