    The plan below shows the roof area of my new extension (approx. 27 metres square). All dimensions are in metres. All construction work is finished & I now need it felting. I have had a quote from someone who was going to apply four layers of torch-on (3 plus 1 mineral) and he gave me a price of £900.

    To me, this seemed steep as I paid £350 to have my double garage done eight years ago.

    Can anyone advise on what I should expect to pay for this?

    Thanks

    £900 seems about right to me for a torch-on system.

    Never look to do a roof on the cheap, remember it is one of the most important parts of your building.

    Thanks, I'm going to get a few quotes for EPDM as well. Looking at this stuff it seems to have quite a few benefits over torch-on.

    £900 is about right. Materials have increased over the years and so has Insurance costs!!!
    Check he's covered...

    Why go for a four layer system ? Most roofers use the three layer system .

    And using this system you would expect a 10 year guarantee.

    First 3B tack on under layer
    second layer 2mm torch on under layer, Finished with a 4mm torch on mineral cap sheet.

    The EPDM system can be quite expensive. Personally I think its over rated. But each to there own.

    Not that much more than quoted in the first post really, about £1200 and available with at least 15 year insurance backed guarantee

    My concern with GRP is that if there is any air trapped in the layers, this can expand on a hot day & break through, causing a potential leak. I think I'm going to go the EPDM route as it seems by far the most robust.
