My extension roof was leaking a few months back and on close inspection
noticed one of the overlapping roof felts had come away. So I blasted it
with a hot air gun and flattened it down and all seemed well.

I also coated it with Thompson's roof seal. However after a week or so I
spotted that right along the repair loads of tiny holes appeared so coated
it in more roof seal. After another few weeks more holes appeared.

Here is how it looks today a few months since I last coated it.

It has never leaked since I originally heated it with the hot air gun but I
would like to fill the holes with something and completely paint the roof
but don't want the bubbles coming back.

I bought some joint tape as suggested by the Thompson's roof seal site but
I'm not sure that would do the trick.

Any suggestions as to what I can fill the holes with before giving it
another coat of the roof seal? I can't imagine the holes could get any
bigger!

Cheers.

What does the joint tape say to use to stick that down? If it is
something goopy then I'd use that to "fill" the holes and stick the
tape down. Just applying more roof seal isn't likely to tolerate much
movement, see below.

Looks to me that the holes are larger near the edge the roof and get
smaller finally dissappearing. To me it looks like something is on
the move opening up a crack...

It probably is getting to the stage when it needs stripping and
replacing.
It is only good for ten or fifteen years.
Don't leave it too long or you will get rot in the roof structure.
Flat roofs and felt are bad news. Cheap and ****ty solution.
There's better stuff now than bitumous felt to replace it with.

Wise words. Mine was in poor condition - a flat roof over a porch at
the side of the house, that we never use. Long story short - I suddenly
realised that I could not open the door from the house into the porch -
jammed solid. Could not open the door from the garden, either, because
it was locked from the inside. Eventually jemmied open the door from
the house. What a mess. Water everywhere. Thick mould all over the
floor, walls and ceiling. Growths of 'stuff' - fleshy tubes about six
inches long growing in there. Mushroom shaped things. Absolutely
disgusting. Roof has now been replaced. What should have been a change
of felt resulted in change of all the wood, too. Dehumidifier running
24/7, and requires emptying twice a day.

Moral of the story - don't ignore a failing flat roof!

I find Evostik "Flashband" tape is very effective and lasts well. I
expect what you've got is the same or equivalent. It's a thin, greyed,
metal foil stuck down with a bituminous goop. Your felt looks in
pretty good shape apart from the crack, and assuming nothing is
tearing apart below the tape should last the rest of the life of the
felt.

Its self adhesive which I can't imagine would hold very well.

Yeah the holes do get slightly bigger near the roof edge. What amazes me
though is it appears water tight even with the holes.
Yet before I coated the roof the water pouring in through my inside wall.
I put the holes down to the exceptionally high temperatures we had here
recently as this part of the roof is in the sun all day.

Thanks.

Yeah you are probably right as we have been in the house for 11 years and
the roof was done about 15 years previously so we've well exceeded its life
span.

The only problem being is this part is the join with the next door neighbour
and unfortunately they have never moved in despite buying the house several
months ago.

Thanks I'll have a look at this. Do you know if it can be overpainted at
all?
