Introduction: When it comes to roofing systems, every component plays a crucial role in ensuring the longevity and efficiency of the structure. The underlayment is a silent yet essential guardian, particularly in felt roof systems. Gillingham Roofing Services understands the significance of this often-overlooked layer and its impact on the overall performance of a roof.


What is Underlayment?

Underlayment is a protective layer between the roof deck and the final roofing material. In felt roof systems, it is a barrier against water infiltration, provides additional insulation, and enhances the roof’s durability.


Waterproofing Properties

One of the primary functions of underlayment in felt roof systems is waterproofing. Felt roofs typically consist of layers of bitumen-saturated felt membranes, which are susceptible to water penetration if not adequately protected. The underlayment acts as a secondary barrier, preventing moisture from seeping through to the roof deck and causing damage to the structure.


Enhanced Durability

Felt roofs are exposed to various environmental stressors such as UV radiation, temperature fluctuations, and mechanical damage. Without proper protection, these factors can compromise the roofing system’s integrity over time. The underlayment provides an additional layer of defence against these elements, prolonging the roof’s lifespan and reducing the need for frequent repairs.


Improved Insulation

In addition to its waterproofing properties, underlayment also offers thermal insulation benefits. Adding an extra layer of material between the roof deck and the final roofing membrane helps regulate indoor temperatures and reduce energy consumption. This is especially advantageous in regions with extreme weather conditions, where proper insulation can enhance comfort and energy efficiency.


Types of Underlayment

Various types of underlayment are available for felt roof systems, each offering unique advantages based on the project’s specific requirements. Common options include traditional asphalt-saturated felt, synthetic underlayment, and self-adhering membranes. Gillingham Roofing Services can help clients choose the most suitable underlayment based on climate, budget, and performance expectations.


Professional Installation Matters

While the role of underlayment in felt roof systems is undeniable, its effectiveness ultimately depends on proper installation. Improperly installed underlayment can lead to premature deterioration of the roofing system and compromise its performance. That’s why it’s essential to entrust the installation process to experienced professionals like Gillingham Roofing Services, who have the expertise and knowledge to ensure quality workmanship.


Conclusion: In roofing, the underlayment may not always be the show’s star, but its role in ensuring the durability, waterproofing, and insulation of felt roof systems cannot be overstated. Underlayment can help safeguard residential and commercial properties against the elements for years to come with proper installation and maintenance.
