Felt Roofing Services

Modern felt roofing systems provide an excellent balance of durability, flexibility and value. We install advanced polyester-based felts designed to withstand the UK climate.

Suitable applications include:

  • Garages and extensions
  • Dormers and porches
  • Commercial flat roofs
  • Roof terraces and balconies

Our felt roofing installations are completed to a high technical standard and backed by 10, 15 or 20-year guarantees.

In addition to our domestic work, we are trusted contractors for local authorities and national utility companies, delivering specialist roofing works on infrastructure and public buildings.

Modern felt roofing technology

Contemporary felt systems bear little resemblance to older three-layer built-up roofing:

Polymer-modified bitumen – Modern felts incorporate SBS (Styrene-Butadiene-Styrene) or APP (Atactic Polypropylene) modifiers that dramatically improve flexibility, temperature tolerance and longevity.

Polyester reinforcement – Superior to traditional glass fibre, polyester reinforcement provides excellent tear resistance and dimensional stability.

Mineral finishes – Coloured mineral surfaces protect the bitumen from UV degradation while improving aesthetics and reducing heat absorption.

Torch-on application – Hot welding creates homogeneous joints between sheets, eliminating the weak points found in nailed systems.

Felt Roofing Installation Process

Professional felt roofing installation is essential to ensure optimal performance:

  • Surface preparation – Existing deck must be sound, dry and smooth. We repair or replace deteriorated substrates before applying new felt.
  • Vapour control layer – Prevents moisture migration into roof construction where appropriate.
  • Insulation installation – Rigid insulation boards achieve required thermal performance while providing a stable base for the felt membrane.
  • First layer application – Perforated underlay or bonded first layer creates the waterproof foundation.
  • Cap sheet installation – Mineral-finished cap sheet provides weather protection and UV resistance.
  • Detailing – Upstands, outlets and penetrations require careful detailing for long-term weathertightness.

 

Felt Roof Maintenance

While modern felt systems are substantially more durable than older alternatives, periodic maintenance extends lifespan. Therefore, we recommend the following:

  • Annual visual inspection for surface damage
  • Immediate repair of punctures or tears
  • Keep drainage clear of debris
  • Monitor for standing water or ponding
  • Apply solar-reflective coatings where necessary

 

When felt roofing is the right choice

Felt roofing systems are best suited to projects where:

  • Budget constraints limit material options
  • Quick installation minimises disruption
  • Traditional appearance is preferred
  • Existing felt requires like-for-like replacement
  • Building use doesn’t justify premium systems

We provide honest advice on material selection, ensuring you receive the most appropriate solution for your circumstances and budget.
