How to Choose the Right Closure Strips for Your Metal Roofing

Nov 27, 2023

If you have chosen metal roofing for your building, you might be pondering over the question, “Do I need closure strips for metal roofing?” The short answer is yes. But why is it so necessary, and what role do these seemingly small components play in your roofing system? Let’s delve deeper.

Importance of Closure Strips

Metal roofing, while being incredibly durable and long-lasting, has its own set of challenges. One of them is the slight gaps and spaces that could potentially occur between the panels and the roof deck. That’s where metal roofing closure strips come into the picture.

Closure strips for metal roofing are designed to fill these gaps, ensuring there are no openings for water, insects, or air to penetrate. This means they play a crucial role in insulating your building, enhancing energy efficiency, and preventing leakages. The absence of closure strips can lead to a variety of issues, such as moisture accumulation that could eventually result in rusting and degradation of the metal roof.

Types of Closure Strips

Primarily, there are two types of closure strips – solid and vented. Solid closure strips are used to fill spaces and prevent water and air infiltration completely. On the other hand, vented closure strips, as their name suggests, allow a certain degree of air circulation, proving beneficial in preventing condensation under the metal roof.

Your choice between solid and vented closure strips would depend on the specific needs of your building and the local climate conditions. It’s always a good idea to discuss this with your roofing contractor to make the right choice.

In Conclusion

In a nutshell, closure strips for metal roofing are indeed important. They not only provide a secure, tight fit for your metal roofing panels but also contribute to the overall longevity and performance of your roof. So, if you’re considering a metal roof for your building, don’t overlook the role of roof closure strips. When installed correctly, they can go a long way in ensuring a durable and efficient roofing system.

What are Closure Strips for Metal Roofing?

Closure strips are an essential component of metal roofing systems. They are designed to seal the gaps and spaces between the metal roof panels and the roof deck, which helps to prevent air infiltration, and moisture seepage. This is a critical aspect of your roof’s overall performance and longevity.

Constructed typically from foam or plastic materials, metal roofing closure strips come in a variety of shapes and sizes to accommodate different types of metal roofing profiles. For instance, you might find closure strips with corrugated or squared profiles, depending on the design of your metal roof. The closure strips are flexible and durable, designed to maintain their form and function even under extreme weather conditions.

Why are Metal Roofing Closure Strips Important?

Closure strips for metal roofing play a vital role in the overall efficiency and durability of your roofing system. They help to create a seal between the metal roofing panels and the roof deck, blocking out wind, rain, snow, and other environmental elements that could otherwise penetrate your roof and damage your home.

Without proper closure strips, your metal roof could be at risk of leaks and moisture damage. The moisture can seep into the gaps between the roof panels and the decking, leading to problems like mold growth, wood rot, and even structural damage. By sealing these gaps, closure strips help to protect your home and extend the lifespan of your metal roof.

Understanding the Types of Roof Closure Strips

There are two main types of closure strips: solid and vented. Solid closure strips are designed to completely seal off the gaps between your roof panels and the deck. They’re often used on the ridge cap, where the highest point of a roof is, to prevent moisture from seeping in. Vented closure strips, on the other hand, are designed to allow some air movement while still blocking out moisture. These are often used in conjunction with ridge vents to promote airflow and regulate attic temperatures.

In conclusion, closure strips for metal roofing are a small, yet critical component of your roofing system. They help to seal your roof, safeguarding your home against potential water damage and extending the lifespan of your roof. Given their importance, it’s crucial to ensure they’re installed correctly and replaced promptly when they show signs of wear and tear.

What Are Closure Strips Used For?

Closure strips for metal roofing serve a crucial function in the overall performance and longevity of a metal roof. They are instrumental in ensuring that the roof provides the best protection against elements such as wind, rain, and even small insects and critters.

So, what exactly does a metal roofing closure strip do? Let’s delve into their primary functions.

Prevent Water Infiltration

The first and most important role of roofing closure strips is to prevent water infiltration. When it rains, water can seep into the gaps or spaces in the metal roofing. These gaps may be between the panels or at the ridge cap, which is the highest point of a roof. Closure strips effectively seal off these spaces, preventing water from penetrating your roof.

Keep Out Wind and Debris

Another critical function of metal roof closure strips is to keep out wind and debris. High winds can potentially lift the panels of your metal roof, especially if they find a way into the gaps. Closure strips can help prevent this by creating a tight seal. They also keep out debris and other foreign materials such as leaves and small branches from settling into the spaces between your roof panels.

Prevent Pest Intrusion

By sealing gaps and spaces, roof closure strips can also deter pests such as insects and small critters from entering your roof. Without these closure strips, your roof could potentially become an entry point for pests, leading to infestations.

Ensure Proper Ventilation

Even as they seal off spaces, closure strips for metal roofing also ensure proper ventilation. They’re designed to allow air to flow while blocking out elements that could damage the roof or the interior of your home. Proper ventilation is crucial as it helps to keep the roof and, by extension, the house, cool during the hot summer months.

In conclusion, closure strips are a vital part of a metal roof installation. They ensure that your roof can stand the test of time, providing the essential protection that you need against the elements while maintaining proper ventilation. Without them, water and pests can infiltrate, and wind can dislodge your roof, leading to potential damage and costly repairs.


How to Install Closure Strips for Metal Roofing

Installing closure strips for metal roofing is a relatively straightforward task but it requires attention to detail to ensure a well-sealed roof. These roofing closure strips are essential in closing gaps between the metal roof panels and the roof deck, preventing water and pests from penetrating.

Materials and Tools Required

To install your metal roof closure strips, you will need the following:

  • High-quality roofing sealant
  • Screws or nails for attachment
  • Hammer or screwdriver
  • Measuring tape and marker

Step-by-Step Installation Guide

Follow these steps carefully to install your metal roofing closure strips:

Step 1: Measure and Mark

First, measure the length of the space between the metal roofing panels. Mark the placement of the closure strips along the length of the gap using your measuring tape and marker.

Step 2: Apply Sealant

Apply a generous amount of sealant along the length of the roof where the closure strips will be placed. This will ensure a watertight seal.

Step 3: Place the Closure Strips

Next, align the closure strips with the markings you made. Press them firmly into the sealant to ensure a good seal. Make sure the strips overlap at the ends to prevent gaps.

Step 4: Secure the Closure Strips

Secure the roof closure strips with screws or nails, ensuring they are tight and secure. Overlap the ends of the strips and secure them as well.

Step 5: Repeat the Process

Repeat the process for all necessary areas on the roof. Make sure to check the sealant and closure strips after a few days to ensure they are still secure and sealed tightly.

Proper installation of closure strips for metal roofing not only ensures a watertight roof but also extends the lifespan of the roof. Always consider hiring a professional if you’re unsure about the process.
