In the world of roofing, exposed fastener metal roofs have established a reputation for their rugged durability and straightforward installation process.
With their distinctive appearance and cost-effectiveness, these roofs have become a popular choice for residential and commercial projects alike.
Whether you’re a homeowner looking for a reliable and budget-friendly roof or a contractor seeking insights into this roofing solution, read on to discover the strength and simplicity of exposed fastener metal roofing in Fort Wayne, IN.
What is an Exposed Fastener Metal Roofing System?
An exposed fastener metal roofing system is a type of metal roofing solution that utilizes visible screws or fasteners to secure metal panels to the roof deck.
Unlike concealed fastener systems, exposed fastener systems have fasteners exposed on the surface of the roof.
In this roofing system, metal panels are typically corrugated or ribbed, featuring raised ridges or seams that create a distinctive aesthetic.
The panels are installed by aligning them on the roof deck and fastening them directly through the panels into the roof deck using screws or nails. The fasteners pass through the surface of the panels and are visible from the outside, hence the name “exposed fastener.”
Advantages of Exposed Fastener
Exposed fastener metal roofing systems combine affordability, simplicity, and strength, making them a popular choice for various applications.
- Affordable Roofing Solution – These roofs are generally more cost-effective compared to concealed fastener systems. The simpler installation process and fewer materials required contribute to a lower overall cost. This makes it an attractive option for budget-conscious homeowners or commercial projects with large roof areas.
- Lightweight – Exposed fastener panels are typically thinner and lighter than standing seam panels. This reduces the load on your roofline, preventing structural issues caused by heavier roofing materials.
- Easy Installation – The visible fasteners provide clear guidelines for panel placement and alignment, simplifying the installation process. This can result in faster installation times and potentially lower labor costs.
- Strength and Durability: Exposed fastener metal roofs are known for their strength and durability. The visible fasteners create a secure attachment, ensuring that the metal panels remain firmly in place, even in harsh weather conditions. Metal roofs are resistant to fire, insects, rot, and deterioration, offering a long-lasting roofing solution.
Disadvantages of Exposed Fastener
When considering an exposed fastener metal roofing system, it’s important to weigh these pros and cons against your specific needs, budget, and aesthetic preferences.
- Noise – Exposed fastener metal roofs can be noisier compared to other roofing systems, especially during heavy rainfall or hailstorms. The sound of raindrops hitting the metal panels can be more audible inside the building, due to the way the fasteners are installed and the resulting construction of the roof system. This may be a consideration for those seeking a quieter indoor environment.
- Higher Maintenance – Although metal roofs require less maintenance compared to some other roofing materials, exposed fastener systems may need more attention. The exposed fasteners may experience wear or weathering over time, necessitating periodic inspections and potential replacement to prevent leaks or damage.
- Weak Leak Resistance – One of the main drawbacks of exposed fastener metal roofing systems is the potential for water penetration. Over time, the rubber washers that surround the fasteners can deteriorate, leading to leaks if not properly maintained. Regular inspections and maintenance are crucial to ensure the integrity of the roof and address any potential leakage issues promptly.
Cost of An Exposed Fastener Metal Roofing System
The cost of an exposed fastener metal roofing system can vary depending on several factors. These factors include the size of the roof, the complexity of the installation, the type and quality of materials used, and the location.
On average, the cost of an exposed fastener metal roof is approximately $4.50 per square foot. Other factors that influence the price:
- Metal Type: The cost of the metal panels themselves is a significant component of the overall cost. The type of metal used, such as steel or aluminum, will affect the price. Additionally, the gauge or thickness of the metal panels can impact the cost, with thicker panels generally being more expensive.
- Size: The size and complexity of the roof will affect the overall cost. Larger roofs will require more materials and labor, resulting in higher costs. Additionally, roofs with multiple angles, valleys, dormers, or other architectural features may require more time and expertise during the installation process, potentially increasing the cost.
- Colors and Finishes: Different finishes or coatings, such as painted or galvanized, can also affect the price.
Types of Exposed Fastener Panels
The three types of exposed fastener panels, namely corrugated, box rib, and all-purpose, differ in their design, appearance, and applications.
1. Corrugated – Corrugated panels have a distinctive wavy or ribbed pattern that creates a series of parallel ridges and valleys across the surface of the panel. These panels are known for their strength and durability. The corrugated profile enhances the rigidity of the panels, making them suitable for applications that require structural integrity and load-bearing capabilities. They provide a rugged, industrial aesthetic and are often chosen for their cost-effectiveness and straightforward installation process.
2. Box Rib – Box rib panels, also known as V-beam or V-crimp panels, feature a series of distinct raised ribs or V-shaped crimps that run vertically along the length of the panel. The ribs create a visually appealing linear pattern on the roof’s surface. Box rib panels offer a balance between strength and aesthetics. These panels are suitable for roofs with moderate to steep slopes and are often chosen for their durability, ease of installation, and versatility.
3. All-Purpose – All-purpose panels, also referred to as R-panel or PBR (Purlin Bearing Rib) panels, are characterized by their trapezoidal shape and deep ribs. These panels have a more industrial appearance and are popular in commercial and agricultural settings. The deep ribs provide strength and stability, making them capable of withstanding heavy loads and harsh weather conditions. All-purpose panels are often used for roofs with low slopes, and their versatility makes them suitable for both roofing and wall applications.
