How to Install Blind Rivets for Roofing ?

I reprinted a tutorial video from youbute for one of the tutorials for installing a blind rivet for a metal roof. Other than the different application scenarios, there isn’t a big difference in how the blind rivets are installed. Overall just the following steps:

  1. Pre-drilled holes of appropriate size
  2. Place the prepared blind rivets into the holes.
  3. Completing the installation of blind rivets with a blind rivet gun

The Importance of Using Blind Rivets for Roofing

Although small and insignificant, blind rivets play a vital role in the installation of metal roofs. Blind rivets provide the stability and waterproofing that a roof needs, and they also reduce the need for maintenance and repairs.

  • Attaching Metal Roof Panels: Metal roof panels are attached to the roof structure by means of blind rivets. Blind rivets ensure the overall stability of the roof. This type of connection can withstand the forces and challenges of wind, rain, and other natural environmental conditions.
  • Provide Structural Support: Blind rivets provide structural support between metal roof panels. When metal roof panels are exposed to external pressures, such as wind or gravity loads, blind rivets are able to dissipate and transfer these forces, enhancing the overall stability of the roof.
  • Prevents roof loosening and leakage: It prevents loosening and movement between metal roof panels. This fastening not only maintains the overall appearance of the roof, but also prevents the penetration of moisture and other exterior materials. It is able to prevent roof leaks from occurring.
  • Durability and Corrosion Resistance: Metal roofing has high requirements for fasteners due to long-term exposure to various weather conditions. Blind rivets with good durability and corrosion resistance can keep the function and performance stable for a long time.

Requirements of Blind Rivets for Roofing of Different Materials

1.Different Materials of Roofing

Metal roofing is a roofing material that is widely used on buildings. It has many features that other materials do not have, such as durability, high strength and aesthetics. Next I will give a brief introduction to some common metal roofs.

Steel Roofing

Steel is a common metal roofing material that offers excellent strength and durability. It can be galvanized or coated to increase its corrosion resistance. Steel roofing is often used for large commercial and industrial buildings because of its strength to withstand larger loads.

Aluminum Roofing

Aluminum is a lightweight metal with good corrosion and oxidation resistance. Aluminum roofing is suitable for a variety of building types, including residential and commercial buildings. Its lightweight characteristics make installation easier, while it has good corrosion resistance to environmental factors such as humidity and salinity.

Copper Roofing

Copper is a high-end metal roofing material that offers unique natural beauty and durability. Over time, copper develops a unique oxidized layer that takes on a green or blue-green natural look. Commonly used for projects such as historic buildings, churches and luxury homes, copper roofing showcases unique taste and character.

Zinc Roofing

Zinc is a metal with excellent corrosion resistance and is suitable for metal roofing in all climates. Zinc roofing has excellent durability and self-repairing ability to resist the natural elements such as sun, rain, snow and ice. Zinc roofing is also highly malleable and can be manufactured in a variety of shapes and designs.

2.How to Choose Right Blind Rivets for Roofs with Different Metals

Combinations between different materials may produce bad results. So pay attention to the conflict between materials when choosing blind rivets for roofs made of different metal materials. Blind rivets and metal roofing materials should match to ensure a solid connection and reliability. Below I have listed the points of attention for choosing the right blind rivet material for metal roofing.

Strength and Hardness

The strength and hardness of different metal materials are different. For example, harder metals, steel, need to be joined using blind rivets with higher tensile strength and shear capacity. Softer metals, such as aluminum or copper can be joined using blister rivets with lower tensile strength.So when choosing a blind rivet for your metal roof, you need to consider the strength and hardness of the metal material. Make sure that the blind rivets can adapt to the properties of the metal material.

Corrosiveness

When selecting blind rivets, the interaction between different materials needs to be considered. For example, copper or zinc such materials, you need to choose compatible blind rivets to avoid corrosion caused by electrochemical reactions.

Thickness and Hole Diameter

The thickness of the roof is inconsistent. Thicker metal roofs require a larger riveting range of blind rivets to make the connection. And the diameter of the blind rivets needs to match the holes in the metal roof to ensure a stable connection.

Selection of Appropriate Blind Rivets for Roofing

Types of Blind Rivets for Roofing

1.Standard Blind Rivet (Open Type Blind Rivet)

Open end blind rivets are the most common type of blind rivets. Usually made of aluminum or stainless steel, they have excellent corrosion resistance and tensile strength. In roofing connections, standard blind rivets are commonly used in the following scenarios:

  • Metal Roofing Installation: Fixing the metal roof panels to the fabricated structure
  • Metal Roofing Accessories Installation: Installation of metal roofing accessories such as gutters, drainage systems, weather stripping and edge trims.
  • Roof Equipment Fixing: e.g. vents, skylights or solar panels, etc.
  • Roof Repair and Restoration: When replacing or securing damaged roof panels or fittings, blind rivets can provide a reliable attachment solution.

2.Waterproof Blind Rivet (Bulb Tite Blind Rivet)

The Waterproof Blind Rivet is a connecting fastener specifically designed for use in metal roof waterproofing systems. It is designed with additional sealing and waterproofing features. Watertight blind rivets are usually equipped with a watertight gasket or seal that provides greater watertightness and less risk of water penetration and roof leaks.

Watertight blind rivets have the following characteristics:

  • Tightness
  • Corrosion Resistance
  • Adjustable Length

In roofing, waterproof blind rivets are typically used in the following application scenarios:

  • Metal Roof Waterproofing System: fixing metal roof panels and waterproofing layer
  • Roofing Accessories Installation: Installation of metal roofing accessories such as rainwater harvesting equipment, weathervanes or parapets.
  • Roof Repair and Maintenance: replacing or fixing damaged roof panels or accessories while maintaining the waterproofing of the roof

3.High Strength Structural Blind Rivet

High Strength Structural Blind Rivets are a type of blind rivet used to withstand higher loads and provide a higher strength connection. It utilizes stronger materials and design for roofing connections that require high strength and greater stability.
In roofing, High Strength Structural Blind Rivets are typically used in the following scenarios:

  • Attach metal roofing members such as purlins, beams and braces.
  • Connecting and fixing large-size metal roof panels
  • Connecting and fixing metal reinforcement materials, reinforcement sheets and other structural components

4.Closed End Blind Rivet

Sealed Rivet is a specially designed blind rivet. It has an extra sealing cap that provides better waterproof performance and weather resistance. It has the following three main features:

  • Sealing: Has a built-in sealing gasket or sealant gasket. Protects the roof from water leaks or other environmental impacts.
  • Corrosion Resistance: Made from materials such as aluminum, stainless steel or galvanized steel to provide long term corrosion resistance.
  • High Strength: Possesses high strength and load-bearing capacity to ensure a solid and durable roof.

Sealed rivets mainly help the roof to fulfill several functions:

  • Metal Roof Installation to keep your roof watertight.
  • Installation of vents, skylights, parapets or air strips.
  • Installation of roof sewer systems, securing sewer pipes, fittings, or other components.

Quality Standards and Strength of Roofing Blind Rivets

The tensile strength and load carrying capacity of the blind rivets are important for joining roofs. Proper tensile strength and load carrying capacity ensures that the joints can withstand the forces and loads of normal operating conditions, such as wind, rain, snow or other external pressures. This maintains the stability, durability and safety of the roof.
So when selecting blind rivets for your roof, you need to consider the tensile strength and load carrying capacity based on the requirements of your project. Follow the manufacturer’s installation guidelines and recommendations.

While searching for Roofing Blind Rivets manufacturers and suppliers, it is recommended to prioritize manufacturing plants with international quality certificates. Such as ISO,IATF,DIN,CE,ASTM and other quality certificates.
