The standard roofing is a heavy duty 38kg Green Mineral Felt onto 12mm moisture resistant O.S.B. Boarding. The boarding is fitted onto 50mm x 125mm joists (purlins), spaced at 2′ centres. We can provide alternative roof coverings (please see options below). Should you require Onduline roof sheets – please note, we recommend sterling board underneath, because without the boarding it is liable to condensate during the winter.
Should you wish to upgrade the roofing for cosmetic reasons or to increase the time between maintenance, we offer the following options.
Coloured Polyester Felt – This is available in the same colours as our Felt Tiles (Brown & Grey) and has a life expectancy of about 15 years. Please note this is only available on buildings up to 7m in length.
Metal Profile Roofing. – This has a metal profile roof in black or anthracite grey and comes with a water proof under felt.
Black Onduline Roofing. – This has a corrugated profile and is compressed felt & bitumen, giving a life expectancy of 15 years. The standard colour is black, although other colours are available. Onduline has the benefit of offering a clear roof sheet to allow light, however we recommend sterling board is fitted on the roof before the Onduline to prevent condensation.
Felt Tile Roof. – These are sheets of felt that have a profile of 4 individual tiles within the sheet. They overlap each other and are staggered to provide a tiled effect roof. In addition to the tiles, underlay felt is laid over the boarding beforehand to provide a secondary skin. Angled tin and additional felt strips are fitted to the gables to prevent water ingress, thus providing a life expectancy of over 15 years.
Cedar tiles – These make a beautiful addition to any of our buildings, long lasting and they are set out on battening with under felt
Tapco Slate tiles. – These tiles have a life expectancy of 50 years and look fantastic as a lightweight replacement slate tile, follow the link to find out more about ‘Tapco Slate’
Tiled Roof Option. – Should you require a tiled roof for planning reasons, we would be able to provide and fit the roof trusses (at 600mm centres) with a 30 degree pitch. We clad the gable ends for you, and fit the trusses in place, however a local tiler will need to batten & tile the roof, plus fit the soffits & guttering.
