The Pros and Cons of a Mechanical Standing Seam Roof Profile
The mechanical standing seam roofing system comprises long, interconnecting panels that are positioned vertically. In order to create a safe and waterproof seal, the elevated seams are folded over the top of the panel. Because of this design, there is less chance of leaks and other types of damage because the metal can easily expand and compress. Standing seam metal roofs are a multipurpose roofing solution for structures in commercial and industrial settings. If one is familiar with metal roofing systems, one can determine which type of roofing is ideal for a certain structure. Yet, being aware of the pros and cons of this specific standing seam roof profile can help you pick the best design for your upcoming metal roofing project or installation.
Advantages and Disadvantages of a Mechanical Standing Seam Roof Profile
1. Compatible With Low And Steep-Slope Roofing
Depending on the project requirements, panel design restrictions, and location, mechanically seamed profiles can be used on steep-slope and low-slope roof surfaces. When descending below a particular pitch, a seam sealer is typically necessary. They will offer more weather resistance, which is beneficial for low-slope roofs, since it makes it more difficult for water to run off.
2. Effective Watertightness
The possibility of water remaining on the roof, particularly on low-slope roofs, might be worrisome. Given how these panels are joined, it would be better to use a mechanical lock profile in this situation to increase the water tightness and waterproofing. The risk of leakage into the roof structure is decreased when mechanical seam profiles are installed using a seaming tool because the seam is kept securely closed. Moreover,zinc sheet roofing may also be used to prevent roofing corrosion due to its non-ferrous nature.
3. Robust and long-lasting
You get superior performance from double-lock roofs because they are more secure and weather-tight. The roofs are seamed firmly together by being folded twice, preventing any opportunities for water to leak through any gaps. With the support of C or Z purlins, these panels are mechanically seamed together, giving stiffness to the structure and making it stronger against high winds and severe weather. Many C and Z purlin suppliers offer these purlins with cut-to-length lines that can be easily used at industrial sheds.
4. Expensive And Noise Factor
The mechanical lock panels for this design must be connected together using a manual crimper or electric seamer, which can add to the installation's cost and labour requirements. Due to the effort and expertise required to complete the work correctly, repairs will also be more expensive. Also, the sound of raindrops striking your standing seam metal roof will be noticeable. Your ceiling contributes to noise reduction even if it is set up above decking sandwiched between metal panels.
5.Possibility Of Oil Canning
When installers join the metal panels together too firmly, oil canning happens. If this occurs, the metal panels have space to grow lengthwise but not laterally. Your standing seam metal roof will eventually display oil canning, which starts as a ‘superheated’ look and then develops into a rippling appearance on the metal panels, creating an unappealing problem
After looking through the aforementioned pros and cons, you'll be better able to decide which choice is ideal for your project. Thanks to its durability, mechanical standing-seam roofs have become a popular choice. In essence, this type of roofing raises the seams above the level of the roof, creating panels that reach all the way from the ridge to the eaves.
