The Importance of Choosing High-Quality Felt for Roofing

Introduction

Roofing felt plays a crucial role in protecting your home from the elements. While often hidden beneath tiles or other external coverings, felt acts as a key layer of defence against water ingress, wind uplift, and thermal loss. Yet despite its importance, not all roofing felt is created equal. Choosing a high-quality felt can be the difference between a roof that lasts decades and one that suffers from premature leaks and costly repairs.

At WCT Roofing Long Buckby, we’ve installed and repaired countless roofs throughout Long Buckby and the surrounding Northamptonshire area. Time and again, we’ve seen how the quality of roofing felt directly impacts performance, durability, and long-term value. In this article, we’ll explore why investing in superior roofing felt is essential—and how it benefits both new builds and roof replacements.

What Is Roofing Felt and Why Is It Important?

Roofing felt is a flexible sheet material typically made from fibreglass or polyester, coated with bitumen or synthetic compounds. It is installed beneath the roof covering (such as tiles, slates, or shingles) and serves as a secondary waterproofing barrier.

Its primary functions include:

• Preventing water ingress during heavy rainfall or snow
  
• Protecting against wind-driven rain and draughts
  
• Acting as a temporary waterproof layer during roof installation
  
• Supporting thermal insulation and energy efficiency
  

Whether you’re re-roofing a domestic property or fitting a flat roof system, using high-quality felt ensures this hidden layer continues to do its job effectively for years to come.

Durability and Longevity

One of the most compelling reasons to choose premium felt is durability. Lower-grade felts are more prone to tearing, blistering, and cracking—especially when exposed to temperature fluctuations or UV rays over time. This can lead to premature roof failure and the need for early replacement.

Key advantages of high-quality felt:

• Greater resistance to weather extremes
  
• Better tensile strength and tear resistance
  
• Reduced risk of punctures from foot traffic or falling debris
  

At WCT Roofing Long Buckby, we always recommend materials that have been tried, tested, and proven to perform well in the British climate—ensuring long-term peace of mind.

Enhanced Waterproofing Capabilities

The primary function of roofing felt is to keep moisture out, and not all products are equally effective in doing so. High-quality felt offers advanced waterproofing through multi-layer construction and superior bonding. This ensures water is efficiently shed from the roof surface and away from vulnerable areas like valleys and junctions.

Look for felts that offer:

• Multi-layer laminate construction
  
• Heat-bonded seams or cold adhesive compatibility
  
• Resistance to water pooling or capillary action
  

Proper installation combined with reliable materials means less chance of damp patches, rot, or mould forming in the structure below.

Better Fit and Finish

Roofing felt must be flexible and manageable for accurate installation, particularly around tricky areas like eaves, hips, and roof penetrations. Inferior felt can be brittle, difficult to manipulate, and prone to splitting during fitting—leading to weak spots in the finished roof.

A superior felt will:

• Lay flat without excessive creasing
  
• Conform well to contours and edges
  
• Allow for cleaner joints and overlaps
  

This not only improves the roof’s overall performance but also enhances the professionalism of the finished job, both visually and structurally.

Energy Efficiency and Insulation Support

Modern high-performance felts can also help regulate a building’s temperature. By forming an airtight layer under the external roofing material, quality felt reduces unwanted heat loss in winter and heat gain in summer.

Benefits include:

• Supporting a more comfortable indoor environment
  
• Helping reduce energy consumption
  
• Enhancing the effectiveness of roof insulation
  

This is particularly valuable for homeowners in Northamptonshire looking to improve the sustainability of their homes or meet modern building standards.

Cost-Effectiveness Over Time

While premium felt may come at a higher upfront cost than basic options, the long-term value is far superior. Choosing better materials at the outset often means fewer call-outs, lower maintenance costs, and a longer lifespan for your roof overall.

Long-term savings come from:

• Avoiding premature repairs or re-roofing
  
• Less frequent maintenance visits
  
• Improved protection for the structure beneath
  

At WCT Roofing Long Buckby, we believe in delivering roofing solutions that offer true value—not just short-term fixes.
