Repair roofing felt from inside loft

    What is the best way to repair some tears in roof felt (inside loft space)? Is
    there some product something like a rubber patch for bike inner-tune repairs I
    can just stick on - or maybe some gunge I can use to stick on another piece of
    felt over the tear?
    Thanks

    We are talking about the under tile felt or "sarking" here are we?

    If so I would have thought that ordinary felt adhesive would do the job
    with a piece of underfelt as a patch. You could also probably use "torch
    on" felt if you are feeling brave enough to wield a blow torch in the
    loft (make sure you have a fire extinguisher handy though!).

    You need a bitumen based roffing felt adhesive as used to stick
    down roofing felt.

    To improve adhesion warm up before use ie put hot air from hair dryer
    on tin for few minutes just before using: support felt whilst it grips.

    I take it you mean the sarking? Shouldn't worry about it too much
    unless water is getting in but that would indicate a more serious
    problem with the primary roof covering...

    You don't really want to just "stick a patch on" water will collect
    behind it.
    /
    Sarking> /g/ <patch
    / /
    / g = glue
    /w/ w = trapped water
    /w/
    /g/
    /

    The patch needs to overlap the lower remaining sarking and preferably
    extend underneath the next lath.


    /
    Sarking> // < patch
    //
    --/
    //
    patch > // < sarking
    L//
    //

    With good overlaps you don't need any glue just clout nails through
    the felt into the rafters each side. This works, BTDTGTTS, using old
    feed bags as patches during a F8 Gale when the slates where off the
    barn roof and the old sarking was getting torn to shreds.
