    I have a 16ft x 8 ft asphalt (I think that's what it's called, softish dark grey stuff)) roof over my front basement area, gets walked a lot as it's between the front door and the pavement, in the city. A few bubbles have appeared, a couple have burst, but the rest is in good condition and not leaking at all (yet!) Can I get rid of these bubbles by heating, using a hot air paint stripper? Or any other suggestions please? I don't want to replace the roof yet a it looks only about 10 years old and mostly fine.
    Thanks

    To fix yourself and will last=hammer blisters flat,brush,clean,make sure dry,apply acrypol(3 coats) this stuff costs around £45 per tin,expensive yes but one of the few paint one repair compounds that works/lasts/can be wlaked on/wont get sticky in warm weather/ideal for the type of repair you need and anyone can do it. ;)

    Thanks, Cumbrianroofer. I'll do that.
    That sounds good stuff, also do you think it'd seal up a drip in my daughter's kitchen too (if we get dry weather long enough to stop the drip of course) Arched ceiling in Georgian basement flat, under the pavement, constant drip from lower bulge since she moved in 6 months ago. Had it tested and not mains, but seems to lessen when it hasn't rained for a week. Had pavement up and sealed top of concrete slab over arch with bitumen, so the water must be travelling! But could possibly coat lower parts of ceiling with the acropol when dried out (hoping for a good dry summer!)? What do you think? Thanks

    Dont know without seeing it,are you meaning try to fix leak by repairing ceiling on inside?if so not a chance leeaks cannot be fixed from underneat if thats what you mean.Bitumastic is only any good for short term repairs and has trouble bonding unless area is clean,dry and primed even then its only e temp thing.Acrypol lasts if applied right in certain repairs.ps,acrypol actually bonds to wet surfaces but for best results dry.

    What i mean is it will not stick to his feet in warm weather like bitumastic and then end up on his carpets,only going to be a small areas anyway where blisters are + only likley to be slippery when wet,stop picking faults ;) :LOL:

    The bubbles would be walked on but I'll only coat the bubbled parts, when they're hammered flat. So worth a try.
    The kitchen ceiling, yes it's an old coal hole! is a last ditch attempt, all redone from top,taken up pavement etc, Water must be travelling between waterproofed layers. It's arched, so thought I'd try to coat the lower arch, front to back, to divert the water, when it's very dry of course, after a drought! Someone in the recent past, filled above arch with concrete so no chance of getting that out without rebuilding the lot. The only other thing i can think of is a funnel and plastic tube!
    By the way I'm a she,so it's 'her' shoes slipping on it!
    Thanks
