Mineral Felt Roofing Specialists in
Worcester

Mineral felt remains a highly effective, cost-efficient choice for flat roof waterproofing. Modern systems utilise SBS-modified bitumen, which offers significant improvements in elasticity and durability compared to traditional roofing materials. These systems are designed to resist the thermal expansion and contraction cycles that occur throughout the year in Worcestershire. The mineral granule surface provides a protective shield against UV degradation, which helps to extend the lifespan of the underlying bitumen, typically resulting in a roof that can last for 15 to 25 years when correctly installed. This material is particularly well-suited to the varied building stock found in areas like Bromsgrove and Redditch, offering a seamless and traditional finish.

A high-performance flat roof relies on a correct build-up of layers. Our team installs a robust three-layer system designed to prevent moisture buildup and ensure complete water-tightness. The process begins with a perforated venting base layer, which allows the roof structure to breathe, followed by a strong reinforced underlay. The final stage is the installation of a high-performance mineral-surfaced cap sheet. Using precision torch-on application, we melt the bitumen to create a uniform, watertight seal at every lap and seam. We pay particular attention to detailing, ensuring that perimeter drips and lead flashings are installed to professional standards to prevent common issues like ponding or water ingress.

Even the best-installed flat roofs require maintenance to reach their full potential. If your roof is suffering from solar blistering, tears, or localized ponding, we offer comprehensive inspection and repair services. We diagnose the source of the leak, distinguishing between minor surface damage and structural issues that may have affected the timber deck or OSB3 boards underneath. For projects involving the replacement of more than 25 percent of the roof area, we ensure all works comply with current Building Regulations Part L requirements regarding thermal insulation. Whether you are in Evesham or Kidderminster, we can assess whether a repair is viable or if a full system replacement is required to secure your property.

Many of our clients ask how long their investment will last. A high-quality SBS-modified bitumen system generally provides 15 to 25 years of service life, provided the substrate is sound and the installation is handled correctly. Regarding repairs, we always perform a site assessment to see if a cost-effective patch or overlay is suitable, or if the extent of moisture ingress necessitates a total strip and replace. When comparing mineral felt to materials like EPDM rubber, many homeowners find that mineral felt offers a more traditional aesthetic and is often easier to repair if accidental damage occurs.
