Commercial steel roofing experts can help you understand the different roofing solutions
Commercial steel roofing experts in Asheboro NC can help maintain a functional roof. Commercial steel roofing is a popular choice for many businesses and industrial structures due to its durability, longevity, and low maintenance requirements. The type of steel used in commercial steel roofing plays a crucial role in ensuring the roof’s performance and resilience against various environmental factors. In this article, we will explore the different types of steel commonly used for commercial steel roofing and delve into the methods employed by roofers to calculate and install these roofing materials.
Types of Steel Used in Commercial Steel Roofing:
1. Galvanized Steel:
One of the most common types of steel used in commercial roofing is galvanized steel. This steel is coated with a layer of zinc to protect it from corrosion. The galvanization process involves immersing the steel in molten zinc, creating a robust bond that enhances the steel’s resistance to rust and other forms of corrosion. Galvanized steel roofing is known for its affordability and durability, making it a popular choice for commercial applications.
2. Galvalume Steel:
Galvalume steel is another popular option for commercial roofing. It is a type of steel coated with a combination of zinc and aluminum. This coating provides excellent corrosion resistance and heat reflectivity. Galvalume roofing is valued for its longevity and ability to withstand harsh weather conditions. Additionally, its reflective properties contribute to energy efficiency by reducing the absorption of heat.
3. Stainless Steel:
While stainless steel is often associated with industrial and residential applications, it is also used in commercial roofing. Stainless steel is alloyed with chromium, which forms a passive layer on the surface, preventing corrosion and making it highly resistant to rust. Although it tends to be more expensive than other types of steel, its durability and aesthetic appeal make it a suitable choice for certain commercial roofing projects.
4. Corrugated Steel:
Corrugated steel roofing is a distinctive option characterized by its wavy or ribbed pattern. It is commonly made from galvanized or galvalume steel. The corrugation not only adds strength to the roofing panels but also increases their ability to withstand bending and impact. Corrugated steel roofing is frequently used in commercial and agricultural buildings, offering a cost-effective and reliable solution.
Calculating Commercial Steel Roofing:
Roofers employ various methods to calculate the amount of steel needed for a commercial roofing project. These calculations are essential to ensure accurate material estimates and prevent wastage. Here are some key factors considered in the calculation process:
- Roof Measurements:
Accurate measurements of the roof’s surface area are the foundation of any roofing material calculation. Roofers measure the length and width of each section of the roof, accounting for any protrusions such as chimneys or vents. The total roof area is then calculated by summing up the individual measurements.
- Pitch and Slope:
The pitch or slope of the roof is a critical factor that affects the amount of steel required. Steeper roofs generally require more material due to the increased surface area. Roofers take precise measurements of the roof pitch to factor this into their calculations.
- Overlapping and Waste:
Commercial steel roofing panels often have overlapping seams to ensure water tightness. Roofers account for the necessary overlap and add a percentage for waste when calculating the amount of steel needed. This helps accommodate cuts, corners, and any errors that may occur during the installation process.
- Accessories and Trim:
In addition to the main roofing panels, roofers consider the quantity of accessories and trim required for the project. This includes items such as ridge caps, flashing, and gutter systems. These elements are crucial for the functionality and aesthetics of the commercial steel roofing system.
- Local Building Codes and Regulations:
Roofing calculations must also comply with local building codes and regulations. These codes may dictate specific requirements for roofing materials, insulation, and other aspects of the roofing system. Roofers must be familiar with these regulations to ensure that the commercial steel roofing meets all necessary standards.
Once the calculations are complete, and the appropriate type of steel is selected for the commercial roofing project, the installation process begins. Roofers follow a systematic approach to ensure the effective and efficient installation of steel roofing panels.
1. Preparation of the Roof Deck:
Before installing the steel roofing panels, roofers ensure that the roof deck is clean, dry, and free of any debris. They may make necessary repairs to the underlying structure, addressing any issues that could compromise the integrity of the roofing system.
2. Underlayment Installation:
Roofers often install an underlayment as an additional layer of protection between the steel panels and the roof deck. The underlayment acts as a moisture barrier, preventing water infiltration and providing added insulation.
3. Panel Installation:
Steel roofing panels are installed systematically, starting from the eaves and progressing towards the ridge. The panels are secured to the roof deck using screws or other fastening methods, ensuring a secure and weather-tight fit. Proper alignment and overlap are crucial to the overall integrity of the roofing system.
4. Flashing and Trim Installation:
Roofers install flashing around openings, such as chimneys and vents, to prevent water penetration. Trim pieces, including ridge caps and edge trim, are also installed to provide a finished look and enhance the weather resistance of the roof.
5. Sealing and Fastening:
Sealing is a critical step in commercial steel roofing installation. Roofers apply sealant at seams, overlaps, and around fasteners to create a watertight seal. Properly fastening the steel panels is essential to prevent wind uplift and ensure the overall stability of the roofing system.
6. Quality Control and Inspection:
Throughout the installation process, roofers conduct quality control checks to verify that each step is completed accurately. Inspections may be carried out to identify any issues that need immediate attention, ensuring that the final result meets industry standards and specifications.
While commercial steel roofing is known for its low maintenance requirements, periodic inspections and basic maintenance practices are essential to prolong the life of the roofing system.
- Regular Inspections: Roofers or building owners should conduct regular visual inspections of the steel roofing to identify any signs of damage, loose fasteners, or areas that may require attention. Inspections are especially crucial after severe weather events.
- Cleaning Debris: Clearing debris, such as leaves and branches, from the roof surface and gutters is important to prevent water pooling and potential damage. Accumulated debris can impede proper water drainage, leading to issues like corrosion or leaks.
- Checking Sealants and Fasteners: Over time, sealants and fasteners may deteriorate due to exposure to the elements. Periodically checking and reapplying sealant as needed, and tightening or replacing fasteners, help maintain the integrity of the roofing system.
- Addressing Rust and Corrosion: While galvanized and galvalume coatings provide excellent corrosion resistance, no roofing material is entirely immune to rust. Addressing any signs of rust promptly by cleaning and applying an appropriate coating can prevent further deterioration.
- Professional Inspections: Engaging professional roofers for comprehensive inspections at regular intervals is advisable. They can identify potential issues that may not be apparent during routine checks and provide expert recommendations for maintenance or repairs.
In conclusion, the installation and maintenance of commercial steel roofing require careful planning, attention to detail, and adherence to industry best practices. By choosing the right type of steel, following proper installation procedures, and implementing routine maintenance, businesses can enjoy the long-term benefits of a durable and reliable roofing system. Commercial steel roofing not only protects the structure but also contributes to energy efficiency and overall sustainability.
