Wind is a powerful nature tool to test your roof because of its unpredictable yet inevitable nature. It is powerful on its own, even more when accompanied with storms, and its damages excuses no one. It moves in irregularity, with varying temperature, speed, and pressure. Its damages can manifest through the following:
- Windborne Debris
The wind carries with it debris and other elements from one area to another, causing physical damage, potentially leaks and punctures.
- Displacement of Roof Panels and shingles
Roof shingles can be blown off, uprooted, or detached from its place because of a strong wind force, leaving elements of the roof exposed and susceptible to damage. Sometimes, the roof isn’t detached but creased or curled upward, signifying that the damage is significant nonetheless.
- Structural Damages
Specific parts of the roof, like soffit, fascia, and gutter can be damaged by the wind, by bending the structure, loosening the pieces, and causing cracks, causing future water damage.
Wind Resistance of Polycarbonate Sheets
The wind resistance of polycarbonate sheets depends on a number of considerations. In elevated installations, it is recommended to use thicker polycarbonate as they can handle wind forces stronger than thinner ones can. Polycarbonate types like solid polycarbonate and twin wall polycarbonate are also recommended. Proper installation and workmanship with appropriate number of supports and frames remains crucial to brace impact against windy conditions. Polycarbonate roofing offers good wind resistance, withstanding winds up to 180-220 km/h, and even higher in some cases. Its strength and lightweight nature make it suitable for various applications like patios, carports, and greenhouses, especially in areas prone to high winds or storms.
The slope of the roofing system also improves wind resistance by minimizing the negative pressure that pulls the roof upward. A sufficiently steep slope (30-40 degrees) can generally help in preventing the wind from damaging the roof. Flat or low-sloped roofs, pitched gable roofs, and wide overhangs are more susceptible to wind damage, so they must be considered in creating the roofing systems especially if the area of applications is nearby coastal areas.
