What is Roofing Felt?

Roofing felt, also known as tar paper, is an underlayment material used in roofing. It provides an extra layer of protection by preventing water penetration and offering some insulation. Applied to the roof deck before the final layer, it plays a crucial role in protecting the roof from the elements.

Factors to Consider When Choosing Roofing Felt

When choosing roofing felt, price range, brand reputation, quality, specific project requirements, and adhesive, underlay, and waterproofing capabilities are all crucial factors to consider for long-term waterproofing and weatherproofing benefits.

Price Range

When considering roofing felt, it’s important to understand the different price ranges available. This ensures that you can make an informed decision, choosing an affordable option without sacrificing quality or performance.

When selecting roofing felt, opting for a reputable brand ensures high-quality and reliability. Established brands offer proven performance and durability, reflecting the effectiveness of their products. Trusting a well-known brand assures successful roofing projects.


Ensuring proper waterproofing during the application process is essential for outbuildings like garden sheds. The use of adhesive and clout nails ensures a secure attachment, contributing to effective usage and durability. Waterproofing techniques play a crucial role in the application of roofing felt.


The aesthetics of a structure can be influenced by the colour of the roofing felt. Choosing the right colour enhances the building’s exterior and complements its architectural style, offering visual appeal suitable for various projects.


When considering roofing felt, it’s vital to select the appropriate width, which directly impacts the coverage area, installation efficiency, and handling. Understanding the width options is crucial for informed decisions and effective installation.
