What are the benefits of breathable roofing felt

Breathable roofing felt, also referred to as underlay or membrane, is a paramount element in modern roofing construction. This innovative product is an essential component for roofing systems, providing significant benefits that contribute to the longevity and durability of roofs. This article will look at the advantages that breathable roofing felt offers, particularly within the context of the United Kingdom's unique weather conditions and construction standards.


Understanding Breathable Roofing Felt


Before delving into the benefits, it is crucial to understand what breathable roofing felt is. This material, typically made from water-resistant yet breathable synthetic fabric, is used as an underlay in roof construction. It is installed directly onto the roof decking and beneath the final roofing material, such as tiles or slates. Its breathability is one of its defining features, allowing water vapour to escape from the loft or roof space while preventing water and wind from getting in.


Benefits of Breathable Roofing Felt


1. Improved Ventilation and Moisture Control


One of the primary benefits of breathable roofing felt is its ability to manage moisture effectively. In the U.K., where humidity levels can be high, this is especially important. Breathable underlay allows moisture from inside the house to escape into the atmosphere, reducing the risk of condensation in the loft or roof space. This reduction in moisture levels helps prevent damp and mold growth, which can cause structural damage over time.


2. Enhanced Energy Efficiency


Breathable roofing felt can contribute to a home's overall energy efficiency. By providing an additional layer of insulation, it helps to retain heat within the property during the cold U.K. winters, reducing the need for excessive heating. Simultaneously, it allows moisture to escape, helping to keep the property cool during the summer months. This balance can result in significant energy savings over time.


3. Increased Lifespan of the Roof


The breathable roofing felt's protective properties contribute to the increased longevity of the roof. It acts as a barrier against external elements like wind-driven rain, snow, and ice, which are common in the U.K. It also helps to prevent the entry of dust and insects. By protecting the roof structure from these harmful elements, breathable roofing felt can extend the roof's lifespan, leading to long-term cost savings.


4. Simplified Construction Process


Breathable roofing felt can simplify the construction process. Traditional roofing methods require the installation of ventilation products to allow air circulation and prevent moisture build-up. However, breathable roofing felt eliminates the need for additional ventilation in most cases, reducing the complexity and time involved in the construction process.


5. Compatibility with U.K. Building Regulations


The U.K. Building Regulations advocate for the use of breathable membranes in roof construction to manage moisture effectively. These rules are designed to ensure the safety, health, and comfort of building occupants. The use of breathable roofing felt allows builders and homeowners to comply with these regulations easily.


Conclusion


Breathable roofing felt offers a multitude of benefits for homeowners and builders in the U.K. Its exceptional moisture management, improved energy efficiency, and enhanced roof lifespan make it an invaluable component in roof construction. Additionally, its compatibility with U.K. building regulations and its ability to simplify the construction process makes it a practical choice for the U.K. market.
