One of the bestselling roofing materials here at Greengate's is flat roofing felt, designed to be used on such structures as garden sheds, garages and extensions. Providing a durable, robust barrier against the elements, flat roofing felt is simple to install and here we present a brief step-by-step guide.

  1. As with any construction project, proper preparation is key to achieving a professional finished result. First, check that the surface the felt is to be laid on is suitable: it should be made from sound, moisture-tolerant timber or from chipboard that rests on treated timber joints. For new roofs, ensure that the deck is clean and dry with no protruding nail heads or other obstruc­tions. Where an existing felt roof is to be replaced, all of the old felt, adhesive and nails should be removed and the deck cleaned.
  2. Now it's time to start your first layer, an underlay that will form the base of your new felt roof and should be nailed directly to the deck without adhesive: this will allow the felt to move with the natural thermal and moisture-related movement of the timber. Starting at the roof's lowest edge, roll out the felt perpen­dicular to the direction of the full. Cut to size and, starting at the sheet's centre, work towards the edges, nailing as you go. We recommend galvanised clout nails, which are available in various pack sizes on our website.
  3. Add the next layer, in the same way ensuring that joints are in different places from the first layer. Allow the adhesive to dry for the time stated on the included instruc­tions.
  4. The final top layer can now be added in similar fashion to the second layer.
