Do You Need Roof Vents with Breathable Felt?
As a homeowner, you may wonder if roof vents with breathable felt are necessary. The importance of roof ventilation cannot be underestimated, as it plays a crucial role in maintaining a healthy environment in your home. Without proper ventilation, moisture can accumulate in the roof space, leading to condensation issues, mold growth, and damage.
When it comes to roof ventilation, the need varies depending on the age and construction of your property. Pre-war properties with clay tiles usually have natural ventilation, while modern construction methods with bituminous non-breathable underfelt can trap moisture. Even properties built after the mid-1990s with breathable membrane under the tiles may require additional ventilation, especially during extreme weather conditions.
Proper roof ventilation is necessary in all cases to ensure the movement of air and prevent condensation issues. By allowing moisture to escape and promoting air circulation, roof vents with breathable felt offer several benefits. Not only do they help maintain a healthy environment, but they also prolong the life of your roof and prevent costly damage.
Building Regulations, such as BS5250 and BS5534, provide guidelines for roof ventilation to prevent condensation problems. Compliance with these regulations is crucial for new build and most refurbishment projects. To ensure compliance and the best results, consult with professionals and use BBA-approved products for ventilation.

Roof Ventilation Options for Different Property Types
When it comes to roof ventilation, different property types have different needs. Understanding the ventilation requirements for each type can help ensure a healthy and structurally sound roof. Let’s explore the ventilation options for pre-war properties, post-war properties, and properties built after the mid-1990s.
1. Ventilation for Pre-war Properties
Pre-war properties often have clay tiles that provide natural ventilation. However, these roofs may need to be updated to meet current regulations. If you own a pre-war property, it’s essential to assess the condition of your roof and consider the need for reroofing. Upgrading to modern roofing materials with built-in ventilation solutions can help prevent condensation issues and promote better airflow.
2. Ventilation for Post-war Properties
Post-war properties typically have bituminous non-breathable underfelt, which can trap moisture and lead to condensation problems. To address this issue, additional ventilation options can be installed. Vent tiles, which allow air to flow through the roof space, are a popular choice. Soffit and fascia vents can also be installed to provide a continuous airflow from the eaves to the ridge. These ventilation solutions help remove excess moisture and maintain a balanced environment in the roof space.
3. Ventilation for Properties Built after the Mid-1990s
Properties built after the mid-1990s often have breathable membrane under the tiles. While this membrane provides some level of ventilation, it may still be overwhelmed during extreme weather conditions. If you have a newer property, it’s important to consider additional ventilation options, especially if you live in an area prone to heavy rain or high humidity. By ensuring proper ventilation, you can prevent condensation issues and protect the integrity of your roof.
When choosing roofing materials for any property type, it’s crucial to consider the ventilation requirements. Opting for materials that promote airflow and prevent moisture buildup can significantly reduce the risk of condensation problems. Consult with a professional roofer who can assess your specific property and recommend the best ventilation solutions for your needs.

Benefits of Roof Ventilation with Breathable Felt
Proper roof ventilation is essential for maintaining the health of your roof and preventing moisture-related issues such as condensation, mold, and dampness. When using breathable felt as an underlayment, roof ventilation becomes even more crucial to ensure optimal airflow and moisture regulation.
Installing roof vents near the apex and at the eaves allows for a balanced airflow, promoting the escape of moisture and the circulation of fresh air within the roof space. This helps prevent the buildup of condensation and protects the structural integrity of your roof.
By implementing roof ventilation with breathable felt, you can enjoy several benefits. Firstly, it helps create a healthier environment by preventing the growth of mold and mildew, which can have negative impacts on your health. Additionally, proper ventilation extends the lifespan of your roof by reducing the potential for rot and decay caused by excessive moisture.

|Prevents condensation and mold growth
|Promotes air circulation
|Extends the lifespan of the roof
Investing in roof ventilation with breathable felt is a proactive measure that can save you from costly repairs and replacements down the line. It not only protects your roof structure but also safeguards any items stored in the loft space.
When it comes to the installation of roof vents, it is recommended to consult with professionals who can assess your specific needs and provide the most suitable solutions. Using BBA-approved products ensures compliance with industry standards and guarantees the best results.
Building Regulations and Roof Ventilation Compliance
When it comes to roof ventilation, it’s crucial to ensure compliance with building regulations. These regulations, such as BS5250 and BS5534, provide important guidelines to prevent condensation issues and maintain a healthy roof space. Whether you’re embarking on a new build or a refurbishment project, compliance with these regulations is essential.
As responsible building designers, owners, and contractors, we all have a duty to meet these standards. Failure to comply can lead to serious problems in the future, including costly repairs and potential health risks. That’s why it’s essential to consult with professionals and use BBA-approved products for ventilation.
By adhering to the building regulations for roof ventilation, you can ensure the best results and peace of mind. These regulations are designed to protect your property and its occupants, as well as prolong the lifespan of your roof. So, don’t overlook the importance of compliance when it comes to maintaining a healthy and functional roofing system.
Do I need roof vents if I have breathable felt?
Yes, proper roof ventilation is still necessary even with breathable felt. While breathable felt helps prevent condensation, additional ventilation ensures the movement of air and prevents condensation issues in all weather conditions.
What ventilation options are available for pre-war properties?
Pre-war properties with clay tiles usually have natural ventilation. However, they may require reroofing to meet current regulations and ensure proper ventilation.
How can I prevent condensation issues in post-war properties with non-breathable underfelt?
Additional ventilation is essential for post-war properties with bituminous non-breathable underfelt. Vent tiles or soffit/fascia vents can be installed to allow air circulation and prevent condensation problems.
Are breathable membrane under tiles enough for properties built after the mid-1990s?
While breathable membrane under the tiles helps with ventilation, properties built after the mid-1990s may still require additional ventilation, especially in extreme weather conditions. It is crucial to ensure proper ventilation when choosing roofing materials to prevent condensation issues.
What are the benefits of roof ventilation with breathable felt?
