What do you put under corrugated metal roofing?

Corrugated metal roofing is a popular choice for its durability and versatility. However, to ensure its longevity and effectiveness, it is crucial to consider what goes beneath it. The material you put under corrugated metal roofing serves several purposes, including insulation, moisture prevention, and noise reduction. In this article, we will explore the different options available for what you can put under corrugated metal roofing and discuss their benefits.

1. Roofing felt:

One of the most commonly used materials for underlayment is roofing felt. Also known as tar paper or underlayment, roofing felt is a versatile material that provides an extra layer of protection against moisture. It helps prevent water from seeping into the roof structure and causing damage. Roofing felt is available in various weights and qualities, so it is essential to choose a high-quality product suitable for corrugated metal roofing. Additionally, roofing felt also acts as a cushioning layer, reducing noise from rain or hail.

2. Synthetic underlayment:

In recent years, synthetic underlayment has gained popularity as an alternative to traditional roofing felt. Made from polyethylene or polypropylene, synthetic underlayment offers superior waterproofing capabilities, enhanced durability, and increased resistance to UV rays. It is lightweight and easy to handle, making installation quicker and more efficient. Moreover, synthetic underlayment can provide better protection against moisture buildup compared to roofing felt, ensuring the longevity of your corrugated metal roof.

3. Insulation materials:

Insulation is an essential component when it comes to properly protecting your home. Insulation materials can be installed under corrugated metal roofing to regulate the temperature, reduce energy consumption, and increase comfort. Some common insulation options include fiberglass, mineral wool, polystyrene, and polyurethane foam. These materials help prevent heat transfer, keeping the interior space cool in summer and warm in winter. However, it is crucial to choose insulation materials that are compatible with corrugated metal roofing and meet local building codes.

4. Vapor barrier:

Another crucial consideration when installing corrugated metal roofing is the need for a vapor barrier. A vapor barrier is a thin material that prevents moisture from traveling from the interior to the roof deck, where it can cause condensation and potentially lead to mold or wood rot. The barrier can be made of plastic or foil, and it helps maintain the integrity of the roof structure. Installing a vapor barrier is particularly important in areas with high humidity levels or when there is a high potential for condensation.

In conclusion, when installing corrugated metal roofing, it is vital to give careful thought to what goes beneath it. Roofing felt and synthetic underlayment provide an additional protective layer against moisture, while also reducing noise. Insulation materials help regulate the temperature and increase energy efficiency. Lastly, a vapor barrier is crucial to prevent condensation and potential damage to the roof structure. By choosing the right materials for what you put under your corrugated metal roofing, you can ensure its longevity, protect your home from moisture-related issues, and create a comfortable living environment.
