What You Need to Know About Foam Closure Strips and Metal Roofing

March 9, 2023by Joe0

There are many important factors to consider when installing a metal roof. However, one of the most often overlooked aspects of this process is foam closure strips. These small pieces of foam can make a big difference in terms of the overall quality and durability of your metal roofing system. This article will discuss what foam closure strips are and why they are so important for metal roofs.

What are Foam Closure Strips?

Foam closure strips are small pieces of foam that are used to seal the joints between adjacent metal panels on a metal roof. They help ensure a tight and secure fit and also provide additional insulation for the structure below. The shape, size, and thickness of these strips vary depending on the type of metal roofing system being installed.

There are a variety of sizes, so it’s important to know what type of metal roof you have before selecting the right foam closure strips. Furthermore, some foam closure strips are designed specifically for use with corrugated metal roofs, while others are intended for use with flat panels.

Why Are Foam Closure Strips Important?

Foam closure strips are important for several reasons. They help to create a tight seal between the panels on a metal roof and reduce the risk of water infiltration or condensation buildup underneath the structure.

Your contractor will be able to advise you on the best type of foam closure strips for your metal roofing system, but it is important to keep in mind that these strips should always be installed when installing a new metal roof. Without them, you could experience problems with water leakage or condensation in the future.

What Should You Consider When Buying Foam Closure Strips

When purchasing foam closure strips for your metal roof, you should consider the size and shape of the metal panels, as well as the type of metal used. Additionally, it is important to select a product with good thermal insulation properties and UV protection. Make sure to purchase enough strips for your entire project and follow any instructions provided by the manufacturer carefully.

It is important to keep in mind that foam closure strips should only be installed by qualified professionals who have experience working with metal roofs. Improper installation can lead to problems down the road, so it’s best to leave this task to professionals who understand how these systems work.

The Benefits of Installing Foam Closure Strips

Moisture Resistance

Foam closure strips help to create a tight seal that prevents moisture from entering the structure. This helps protect your building and its contents from damage due to water infiltration. This will also help to prolong the life of your metal roofing system. Having a moisture-resistant roof can also help you save money on energy costs by reducing the amount of air that escapes from your home.


Foam closure strips provide additional insulation for your building, which helps reduce heating and cooling costs. This is especially beneficial in climates where temperatures can fluctuate drastically from summer to winter. Your roof will be better insulated, which can help keep your building at a comfortable temperature all year round.

Keeps out pests

Foam closure strips also act as a deterrent to pest infiltration, helping to keep pests such as rodents and insects out of your home or building. This can help to ensure the health and safety of your occupants.

Noise reduction

Foam closure strips can also help reduce noise from outside sources, such as traffic or nearby construction. This can provide a more peaceful and comfortable environment for those living in the structure.

Minimizes light

Metal roofing will have voids within the highs and lows of the panel design. Foam closure strips can help to reduce the amount of light that enters a structure, preventing glare and heat from entering the interior. The light reduction will also help to keep the building cooler in the summer months, reducing cooling costs. 

Improved Durability

Foam closure strips also help to protect your metal roofing system from wear and tear caused by weather exposure. This will increase the overall durability of your roofing system, saving you money on repairs or replacements down the road. A well-maintained metal roof can last for decades, so investing in foam closure strips is an excellent way to ensure the longevity of your roof.

Maintenance of Foam Closure Strips

Foam closure strips should be inspected and maintained regularly to ensure they are still providing a tight seal between the metal panels on your roof. It is also important to keep an eye out for any signs of wear and tear, such as cracking or splitting. If any damage is found, it is important to replace the foam closure strip immediately to prevent further damage from occurring.

Cost of Installing Foam Closure Strips

The cost of foam closure strips depends on the size, material, and type of your metal roofing system. This does not include labour costs or other associated expenses, such as disposal fees. Professional installation is recommended for optimal results, so it is best to consult a qualified contractor to get an accurate estimate of installation costs.

Foam closure strips are an essential part of a properly installed metal roof. They provide additional insulation, moisture resistance, noise reduction, and improved durability for your roofing system. Furthermore, they help keep out pests and minimize the amount of light entering your structure. To ensure their effectiveness and longevity, it is important to inspect and maintain your foam closure strips regularly. With proper care and maintenance, you can enjoy the benefits of these foam strips for many years to come!
