Metal roof systems are popular in architectural design because of their advantages such as durability, ease of maintenance, and low cost. If built and installed correctly, the service life can be more than 20 years. Therefore, it is a very good choice for owners who want to save money on roof decoration and maintenance.
Not all Anti-Corrosion Sheet Metal Roofing is the same. The length of service life depends on various factors. If install the same roof system in unknown areas, the service life will be different. That’s why it’s necessary for experienced contractors to install roofs. The contractor must have a comprehensive understanding of the characteristics of the various roofs.
This article discusses the two most commonly used types of roof systems in self-storage facility design and their advantages and disadvantages. First of all, understand the typical characteristics of the roof.
There are many types of roof slabs for self-storage, which vary in width, length, and thickness. Some also need to consider insulation, slope, fastening techniques, finishes, and coatings. When considering the installation of a new roof or replacement of the roof, the operator must have a clear understanding of these basic elements in order to install the roof well.
First, measure the length and thickness of the panel. The most common thicknesses are 24 and 26. In general, panel 26 should not be too long due to the wave effect after installation. The 24 gauge panels are more robust and can be used for longer lengths. This reduces the wave effect and the number of horizontal joints required.
Next, consider the type and finish. Self-service metal storage helps improve the aesthetics of the roof. The greater the slope, the more obvious the distance between the roof and the ground. it can achieve different appearances by varying the width of the seams between the panels and using various seam types: stripe, wavy, flat, or ribbed. They also come in a variety of colors and surface treatments, including surface grinding. Common finishing mills include aluminum, aluminum zinc alloys, coated steel, stainless steel, and copper.
The most expensive and longest-lived metal roofs are stainless steel and copper. Aluminum galvanized sheet and galvanized sheet can be polished or painted. Please note when choosing warranty terms. Products for metal panels include watertight / surface warranty or surface only warranty. The combination of metal type and surface treatment is usually related to the surface treatment warranty period. Please be sure to check the scope and duration of the warranty covered in the warranty.
Bare fastener metal roof is widely used and easy to install. It consists of sheet metal and is fixed to the vertical and horizontal joints of the roof with screws and neoprene or rubber gaskets. It is visually attractive and cost-effective, but it can’t adapt to the expansion and contraction of the roof caused by wind or temperature changes.
The roof is made up of concealed, mechanically stitched panels. The fastener is under the panel and fixed on the purlin. The panel slides onto them. This eliminates the need for fasteners at the vertical joints, allowing the panel to move as it expands and contracts. This roof type is more expensive to install but has the advantage of longer waterproof life.
The choice between the two types usually depends on the budget, the expected duration of ownership, and the location of the business. Maintenance tolerances and clogging are also factors. Here are the obvious advantages and disadvantages of both.
On the bright side, this rooftop is cheaper. The main reason for cost savings compared to concealed roofs is the use of wider and thinner panels (up to 36 inches wide and 26 inches thick) for lower costs. Due to faster lapping technology and vertical installation, the labor force in the installation process is also reduced. As long as the roof has a good finish and is properly installed according to its environment and climate, the system can also adapt to weather conditions.
On the other hand, exposed fasteners require the erector to make holes in the roof, which can cause problems. Water seepage is one of the most common problems in this system. If the fastener is too tight or too few, it will cause leakage. As the system cannot adapt to the expansion and contraction of the metal, the fasteners will be drilled and leaked over time. The system requires so many holes in the roof, and leakage seems inevitable, so it is unlikely to find a long-term waterproof warranty.
Exposed fasteners require more frequent maintenance, so he must pay close attention to the roof. It is recommended to check the condition of fasteners regularly and replace the damaged fasteners in bad condition.
Finally, exposed fastener roofs cannot reach low slopes. A slope of more than 1 inch per foot is recommended as this will better allow water to flow down the roof and help prevent water from accumulating.
An obvious advantage of using concealed metal roofs is that fasteners are not exposed to ultraviolet light, moisture, wind, and other factors that can cause them to wear over time. From an aesthetic point of view, these roofs look more fashionable because there are no holes in the roofs, which makes them more waterproof.
The vertical roof is retractable, while the concealed clip system requires less maintenance. Of course, maintenance is still essential and should be carried out by a professional contractor to ensure that the roof reaches the design durability. Finally, although the recommended roof slope is 1 inch per foot or more, the manufacturer provides a slope as low as 1 / 4 inch.
Hidden roofs are more expensive, although hidden roofs are not always the most expensive system compared to sheet metal and other stamped metal materials. It involves more labor-intensive equipment and fewer qualified contractors. The installation of the system is complex and cumbersome and requires careful production and an accurate multi-step process. It is difficult to find experienced contractors with a reliable track record.
No matter what kind of metal roof system is selected, it has the core advantages of durability, weather resistance, and environmental protection. Metal has the ability to resist strong wind, water mist, and snow. In order to protect the environment, compared with asphalt shingles, metal systems produce much less waste, and asphalt shingles need to be replaced more frequently. Even if the price of these roofs is low, and with proper maintenance and maintenance, the coating can last 20 years or more, which is another advantage.
Understanding the basic design of a roof can help homeowners make informed decisions about balancing installation prices and the total cost of ownership. The company provides roof asset management, assessment, preventive maintenance, repair, repair, and replacement.
