‘Torch-On Felt Roofing’ – One of the traditional methods of flat roofing and still one of the most common in use today, torched-on felt roofing is still widely used for both repair and replacement of flat roofs. Many flat roofs on structures such as:

  • Garages
  • Extensions
  • Kitchens
  • Sheds
  • Outbuildings

Will have there roofs covered with ‘torch-on’ felt – this system is also sometimes known as ‘built-up’ felt roofing. Our staff are fully trained and experienced in the use of torched on mineral felt – both for repairs and replacement flat roofing – and will ensure that the whole roof, including edges and features, is fully sealed and water-tight.

Rubber EPDM – Rubber EPDM roof coverings are a more modern flat roofing material which offer greater benefits than traditional felt roofing, including:

  • Greater Durability and Longer Life – Rubber roof membranes are designed to withstand everything the weather can throw at us, with greater resistance to UV light, heat, cold, frost and water, rubber roofing materials have a life expectancy far longer than felt roofing and can come with guarantees of over 20 years.
  • Greater Flexibility – Unlike mineral felt and other traditional methods of flat roofing, rubber roof coverings remain flexible even at low temperatures and offer greater elongation to accommodate any movement within the roof structure.
  • Applied Without Heat or Flames – Rubber roof membranes are applied using a cold-applied adhesive and, unlike torch-on felt, don’t require and heat or flames to install.
  • Fewer Joints or Weak Spots – Rubber roof coverings come in large, seamless sheets rather than smaller rolls, meaning most roofs can be covered without the need for joints – these are generally weak spots in traditional roofing methods.
