    hello



    I have watched roofing videos on youtube and they use a flame to heat up the felt to lay on top of other felt..



    i wondered can you use a simple blow torch like this -- http://www.wickes.co.uk/Rothenberger-Rofire-Torch-C-W-Multigas/p/118675



    to heat the felt up ?


    and can you heat the back of normal shed felt to get it to stick to the old felt below?



    thanks

    Not enough heat, need a proper roofing torch, BUT I wouldn't use one on a wooden shed,otherwise you'll end up with a pile of ash & charred remains.:eek:

    What can use that is quite cheap is a weed torch. They normally come with a can of butane gas for £10-£15. Just keep it about 18 inches from the felt.

    Interesting seeing someone walk behind. I normally walk in front torching, and unroll the felt with a piece of rebar. Got the base layer done today on the extension roof. You have to find the perfect speed, otherwise you won't heat the felt enough, or you'll melt it.

    I find the plumbers torch to be a handy tool for edging and tricky bits. It's got to have a high heat though, MAP gas is the best for it.

    OP: you can get roofing paint that seals the felt joints. TBH I think torched on felt for a shed roof is crazy.

    Got to agree, crazy using torched on felt on a shed, & he won't be the first to burn the shed down applying it.

    Old fashion nowadays, GRP is the way to go.:)

    I did consider it, but I wasn't too sure.

    I trust felt, I haven't worked with GRP before, so I don't know enough about it yet.

    That and the two quotes I got for GRP were more than double the cost of felt. I spent a lot more on groundwork than planned, so I'm trying to keep spending down.:)

    I knew I would be told GRP was better!:D

    Anyway Kiab, how are you doing at the moment? I haven't spoken to you in a while.:)
