Roofing Felt questions? WE have the answers

Roofing felt, plays a crucial role in protecting your home from the elements. This layer of protection lies beneath the main surface of the roof, acting as a secondary barrier against water intrusion. With various options available, homeowners in High Wycombe might wonder which roofing felt is best for their needs.


Let's dive into the details to help you make an informed decision.


Understanding Roofing Felt


Before selecting the best roofing felt, it's essential to understand what it is and why it's important. Roofing felt is a fibrous material, typically made from either natural or synthetic fibres, coated in a waterproofing agent such as bitumen.


It serves multiple purposes: it provides a waterproof layer to protect the roof deck from rain, offers extra insulation, and improves the longevity of your roof by preventing the shingles from sticking to the wood.



"Don't underestimate the importance of roofing felt. It's a crucial layer of protection that can significantly extend the life of your roof."



Types of Roofing Felt


Traditional Organic Felt: Made from organic materials and saturated in asphalt, this type of felt has been a staple in roofing for many years. It's affordable and offers basic protection, making it a popular choice for budget-conscious homeowners. However, it's heavier and not as durable as some of the more modern alternatives.

Fibreglass Felt: This type of felt uses fibreglass strands to reinforce the material, making it stronger and more resistant to tears than organic felt. It's also lighter and less prone to absorbing moisture, which can lead to improved longevity of the roof. Fibreglass felt is particularly suited to High Wycombe's varied climate, providing robust protection against both rain and occasional heat waves.



"Fibreglass felt offers superior strength and moisture resistance compared to traditional organic felt, making it a smart choice for long-term protection."

Synthetic Underlayment: While not "felt" in the traditional sense, synthetic underlayments have become a popular alternative due to their superior durability, water resistance, and ease of installation. These are made from polypropylene or polyester and often treated with waterproof or water-resistant coatings. Synthetic underlayments are more expensive but can offer better protection and a longer lifespan.

Which Roofing Felt Is Best?


The best roofing felt for your home in High Wycombe depends on several factors, including your budget, the climate, and the specific requirements of your roofing project. If cost is a major concern and your roofing project is relatively straightforward, traditional organic felt might be the way to go. It offers basic protection at an affordable price.


For homes in areas prone to extreme weather, or if you're looking for a material that will last longer and offer better protection, fibreglass felt is a great choice. Its enhanced durability and resistance to moisture make it a worthy investment for keeping your home safe and dry.


For those looking for the highest level of protection and longevity, synthetic underlayment is the top choice. Although it comes at a higher initial cost, its benefits, including superior water resistance, durability, and ease of installation, can make it the most cost-effective option in the long run.


When considering which roofing felt to choose, it's also worth consulting with local roofers who understand the specific challenges and requirements of roofing in High Wycombe. Companies like Aztec Roofing can provide valuable insights and recommendations based on years of experience in the area.
