Standing seam is a structural roofing system designed with mechanical field joints that provide enhanced resistance to both weather and wind. In the UAE, standing seam metal roofing sheets are available in diverse shapes such as conical and curved forms, catering to a wide range of architectural designs.
Corrugated metal roofs are installed using fasteners exposed to environmental elements, which leads to eventual loosening of screws, panel holes enlarging, and potential leaks. All corrugated roofs require annual inspection and tightening of fasteners.
Standing seam roofs, on the other hand, feature concealed fasteners, eliminating the need for routine maintenance and providing a longer-lasting solution.
The exposed fasteners in corrugated metal panels require regular maintenance to ensure panels don’t loosen in high wind conditions. In windy regions, it's crucial to frequently inspect and tighten these fasteners.
With standing seam roofing, wind resistance is greatly enhanced. The panels' side joints are locked and tightly sealed, eliminating the concern of panels becoming loose.
Conventional roofing systems, which rely on exposed fasteners and end lap connections, struggle to maintain their air and water tightness. Over time, metal panels react to temperature changes, compromising the integrity of the roofing system.
Standing seam roofs, however, offer superior tightness, eliminating the gaps and weaknesses often found in traditional systems.
Standing seam systems provide limitless design flexibility, accommodating modern architectural trends far better than conventional roofing systems, which often come with design limitations.
In conventional roofing, fasteners are driven through the panels into the purlins, leaving hundreds or thousands of fasteners visible, all of which must be perfectly spaced to prevent water ingress.
In contrast, standing seam roofs utilize a concealed clip-fastened system, where fasteners are hidden beneath the panel. This improves the roof’s appearance and prevents weather elements from affecting the fasteners.
Exposed fastener systems do not allow for natural expansion and contraction of the metal due to temperature changes. In contrast, standing seam systems, with their concealed clips, provide flexibility and allow for thermal movement.
This ensures that fasteners are not exposed to harsh weather conditions, reducing wear over time.
While exposed fastener metal roofs may initially seem like a cost-effective option, their long-term maintenance costs and shorter lifespan should be considered. These systems require regular maintenance, and eventually, may need replacement.
On the other hand, standing seam roofs offer a long-term, reliable solution. Although their initial cost is higher, their reduced maintenance needs and longer lifespan make them a smart investment, particularly for low-slope roofs that require less structural support.
