How Weather Conditions Affect the Performance of GC Sheets

Besides design, strength, structural integrity and aesthetics, most modern roofing solution companies
must consider the weather when manufacturing and installing their products.
Whether it is 40 degrees outside or dropping to the minus range, knowing how galvanized roofing sheets
are affected will help you maintain your roof better. It allows you to protect it from premature degradation
due to the environment.
Hot Weather Considerations
Here are some factors you should consider if you are based in a warmer climate.
1. Heat dissipation
On a structural level, galvanized roofing sheets provide
excellent heat tolerance for use in extremely hot regions. Metal roofs don’t make your room extra
warmer during the summer—it all depends on construction. Utilise deep wall cavities to combat heat. To further cool the
interiors, strategically place vents, doors and windows that allow cross ventilation.
2. Wind resistance
Wind speed creates a significant force on both the bottom and top sides of roof cladding. That’s why wind speed is a
critical factor when designing and installing a roof. The inward force pushes the roof down and the outward force tends
to lift the roof upwards. The only way to balance such force is by providing the right spacing between the purlins and
the correct dimensions of fasteners. If you wish to install Tata Shaktee GC sheets in a cyclonic area,
consult professional fabricators or architects.
3. Proximity to coastline
Another consideration for warm weather is the structure’s proximity to water, particularly a coastline or saltwater
territory. For galvanized roofing sheets, the rate of corrosion is usually linear in most environments.
This implies that the thicker the coating, the more durable your structure will be. Different environments are more or
less corrosive than others, which is why the life of the coating varies considerably for different regions.
Cold Weather Considerations
Extreme cold conditions can affect your roof as well. Let’s discuss some common issues below.
1. Snow shedding
Snow is a serious concern for properties in colder regions. The safety of people inside the structure becomes a cause of
significant concern. Snow, after all, is just water and water is heavy. To minimise damage, it’s important to design the
roof with a steeper slope or pitch and snow guards.
2. Ice dam prevention
If you have heating inside the building and snow collecting on the roof, it will melt but freeze on its way down. This
creates an ice dam.
Galvanized roofing sheets let water run freely if installed at the proper angle. The proper ventilation
and underlayment beneath the panels stop the formation of ice dams.
Tata Shaktee GC sheets undergo several processes and treatments to ensure they are suited for most
extreme weather conditions. Reach out to us if you want to know more!
