Introduction: Regarding roofing solutions for commercial buildings, durability, longevity, and cost-effectiveness are paramount considerations. Felt roofing, also known as built-up roofing (BUR), has been a trusted choice for commercial properties for decades. This blog post will explore the applications and advantages of felt roofing in commercial buildings, highlighting why it remains a popular option for many businesses.

Applications of Felt Roofing in Commercial Buildings:

Flat and Low-Slope Roofs:

  • Felt roofing is ideally suited for flat and low-slope roofs commonly found in commercial buildings such as warehouses, factories, office complexes, and retail outlets. Its flexibility allows for seamless installation on large surface areas, providing reliable protection against the elements.

New Construction and Roof Replacement:

  • For new construction projects or roof replacement endeavours, felt roofing offers versatility and adaptability to various building designs and structures. It can be installed over roofing materials, making it a cost-effective solution for refurbishment projects.

Multi-Layered System:

  • Felt roofing consists of multiple layers of bitumen-saturated roofing felt, alternating with layers of bitumen and topped with a gravel or mineral surface. This multi-layered system creates a robust, resilient roofing membrane that can withstand harsh weather conditions and foot traffic.

Advantages of Felt Roofing in Commercial Buildings:


  • Felt roofing is renowned for its cost-effectiveness, making it an attractive option for budget-conscious commercial property owners. Its relatively low material and installation costs and long-term durability result in a favourable return on investment over the roof’s lifespan.

Durability and Longevity:

  • Built-up felt roofing systems are designed to withstand prolonged exposure to UV radiation, temperature fluctuations, and mechanical stress. With proper maintenance, felt roofs can provide reliable protection for 20 to 30 years, ensuring peace of mind for property owners.

Waterproofing Properties:

  • Felt roofing offers excellent waterproofing properties, effectively sealing out moisture and preventing water infiltration into the building structure. This helps mitigate the risk of water damage, mould growth, and structural deterioration, preserving the integrity of the commercial property.

Thermal Performance:

  • Felt roofing systems can be enhanced with insulation layers to improve thermal performance and energy efficiency. By reducing heat transfer through the roof assembly, felt roofs help maintain comfortable indoor temperatures and lower heating and cooling costs for commercial buildings.

Conclusion: Felt roofing is a popular choice for commercial buildings due to its versatility, cost-effectiveness, durability, and waterproofing properties. For new construction projects or roof replacement endeavours, felt roofing systems offer reliable protection against the elements and ensure long-term performance for commercial properties.
