The Role of Furring Strips in Metal Roofing Installation.
Furring strips play a crucial role in the installation of metal roofing. They offer a range of benefits that contribute to the overall performance and longevity of the roof. Here, we explore the various reasons why furring strips are an essential component of metal roofing installation.
Improved Ventilation and Air Gap
One of the key advantages of furring strips is that they create an air gap between the metal panels and the roof deck. This air gap helps improve ventilation, allowing air to circulate between the two layers. Adequate ventilation is essential in preventing moisture buildup, which can lead to mold, mildew, and other damage. By promoting airflow, furring strips aid in maintaining a dry and well-ventilated roofing system.
Moisture Prevention and Drainage
Furring strips also act as a barrier against moisture infiltration. In the event of rain or snow, they help prevent water from seeping into the roof deck by providing a raised platform for the metal panels. The elevated position facilitates proper water runoff and drainage, reducing the risk of leaks and water-related damage.
Noise Reduction
When it comes to metal roofing, noise reduction is a significant consideration for many homeowners. The installation of furring strips can help dampen external noises by creating an additional layer between the metal panels and the roof deck. This contributes to a more peaceful and comfortable indoor environment, especially during heavy rainfall or hailstorms.
Leveling an Uneven Roof Deck
In some cases, the roof deck may have uneven surfaces or imperfections. Furring strips can help address this issue by providing a level and consistent base for the metal roofing panels. By bridging gaps and irregularities, furring strips ensure a smooth and even installation, enhancing the aesthetics of the roof.
Thermal Break and Energy Efficiency
Another advantage of furring strips is that they act as a thermal break, helping to reduce heat transfer. This can significantly improve energy efficiency in the building, as the air gap created by the furring strips prevents direct contact between the hot metal panels and the roof deck. As a result, less heat is conducted into the living spaces below, leading to potential energy savings and a more comfortable interior.
Overall, furring strips play a vital role in metal roofing installation by providing ventilation, moisture prevention, noise reduction, and improved energy efficiency. They offer numerous benefits that contribute to the performance and longevity of the roof. The careful inclusion of furring strips ensures a well-designed and durable metal roofing system.
Types of Furring Strips for Metal Roofing.
When it comes to metal roofing installations, various types of furring strips are commonly used. Each type offers unique characteristics and benefits that cater to different project requirements. Let’s take a closer look at the different types of furring strips available:
1. Wood Furring Strips
Wood furring strips are a popular choice for their affordability and ease of use. Typically made of treated lumber, they provide a sturdy foundation for the metal roof. Wood furring strips are readily available and can be easily cut and installed.
2. Metal Furring Strips
Metal furring strips, made of galvanized steel or aluminum, offer excellent durability and resistance to corrosion. They provide a strong and stable support system for metal roofing, ensuring long-lasting performance. Metal furring strips are especially beneficial in areas with high humidity or exposure to harsh weather conditions.
3. Composite Furring Strips
Composite furring strips combine the advantages of wood and metal. They are designed to provide the strength and stability of metal strips while incorporating the natural insulation properties of wood. Composite furring strips offer enhanced thermal performance and can help reduce energy consumption.
4. Foam Furring Strips
Foam furring strips are an excellent choice for adding insulation to a metal roofing system. These strips provide thermal insulation, helping to ensure energy efficiency and reduce heat transfer. Foam furring strips can help create a more comfortable and temperature-controlled indoor environment.
Each type of furring strip has its own advantages and considerations. The choice of furring strip depends on factors such as budget, desired insulation performance, and specific project requirements.
| Type | Material | Advantages |
|---|---|---|
| Wood Furring Strips | Treated lumber | Affordable, easy to work with |
| Metal Furring Strips | Galvanized steel or aluminum | Durable, corrosion-resistant |
| Composite Furring Strips | Wood and metal combination | Strength of metal, insulation of wood |
| Foam Furring Strips | Foam material | Thermal insulation, energy-efficient |
Proper Installation of Furring Strips for Metal Roofing.
When it comes to installing furring strips under metal roofing, following proper installation guidelines is essential. This ensures that the furring strips serve their purpose effectively and provide a solid foundation for the metal roofing panels.
Spacing of Furring Strips
The spacing of furring strips is an important aspect of proper installation. Generally, furring strips should be spaced evenly between 16 to 24 inches apart. This spacing allows for proper ventilation and ensures that the weight of the metal roofing panels is distributed evenly.
Installation Guidelines
- Measure and Mark: Before installing furring strips, measure and mark the appropriate spacing on the roof deck. Use a tape measure to ensure accuracy.
- Secure Attachment: Attach the furring strips securely to the roof deck using screws or nails. Make sure they are installed perpendicular to the roof slope.
- Level and Alignment: Ensure that the furring strips are level and aligned properly. This prevents any unevenness in the metal roofing panels and ensures a neater appearance.
The proper installation of furring strips is crucial for several reasons. Firstly, it allows for proper ventilation, which helps prevent moisture buildup and condensation. This promotes a healthier environment and reduces the risk of mold or mildew growth. Secondly, the furring strips provide a solid base for the metal roofing panels, ensuring their stability and preventing any sagging.
Moreover, the correct installation of furring strips creates an even surface for the metal roofing panels, resulting in a more aesthetically pleasing and professional finish.
Overall, following the furring strip installation guidelines ensures that the metal roofing system functions effectively, offering enhanced durability, energy efficiency, and protection for years to come.
| Benefits of Proper Furring Strip Installation |
|---|
| Enhanced ventilation |
| Prevention of moisture buildup and condensation |
| Stability and support for metal roofing panels |

Common Mistakes to Avoid when Using Furring Strips for Metal Roofing.
When it comes to installing metal roofing with furring strips, there are a few common mistakes that should be avoided to ensure a smooth and successful installation. By understanding and avoiding these mistakes, you can save time, money, and potential headaches in the long run.
- Not spacing the furring strips evenly: Proper spacing of furring strips is crucial for the structural integrity of the roof and the overall performance of the metal panels. Failing to space the strips evenly can result in uneven load distribution and compromised stability.
- Skipping the use of a moisture barrier: Installing a moisture barrier beneath the furring strips is essential for preventing water intrusion and protecting the roof deck from potential damage. Neglecting to include a moisture barrier can lead to moisture buildup, rotting, and deterioration of the metal roofing materials.
- Installing the metal panels on an uneven surface: Before installing the metal panels, it is crucial to ensure that the furring strips create a level and even surface. Failure to properly level the furring strips can result in misaligned panels, gaps, and potential leaks.
- Overlooking the importance of noise reduction: Metal roofing can create a certain level of noise during heavy rain or hailstorms. By incorporating soundproofing materials or techniques, such as installing acoustic insulation between the furring strips, you can significantly reduce the noise levels and enhance the comfort of your living space.
By avoiding these common mistakes, you can ensure a successful and long-lasting metal roofing installation. Taking the time to properly plan, prepare, and execute the furring strip installation will result in a sturdy, insulated, and aesthetically pleasing metal roof that will protect your home for years to come.
