If your concrete is a loose or crumbly, I dont think will get the fibre glass and resin to bond to it ...
If you were to use it ... it would have to go up under the tiles and slightly under the felt. It would also have to be spread down the face of the gutter and underneath.
Otherwise the water will get underneath it ... and it will float... that puts you back at square one.
Dont get me wrong, It will work but its a bit messy if you are not used to working with GRP.
As builder says it works well where you have a valley..I have personally made up gutters from fibreglass using the old broken zinc as a former.
If you want to do a good job without the great expense...I would go for Isoflex..you will get it at most DIY stores... and it's just a case of preparation and painting it on.
First of all get everything nice and clean and dry... buy the special primer and follow the instructions...then just apply the top coat of Isoflex.It should be the end of your problem if applied correctly....dont be tempted to go for a cheaper alternative.

These things are called FINLOCK, not Flintlock.
These are a well-known problem in the building industry, I'm afraid.
The Builder has alluded to some sort of possible solution which will last a few years.
Read here for a rather more complete expose on the whole issue (skip down the thread to the answer given by Oxfordlite, about 10 down). No, he isn't me in disguise.

Buildersmate - Obviously they are not that well known 'the builder' didnt know what a concrete gutter was. Apololgies for the incorrect naming of said gutters i stand corrected not that I'm sure it really matters. I have checked the link in your response and as I said in my original post I cannot afford to have them removed by an overpriced builder but thanks anyway.
No probs. I only put the info about the correct name in because if you know the right name, you stand more chance of searching for possible solutions. These things have a lot of 'previous'. I only know about them because they were were on my mum's house. The worst issue is that the guttering is set level, so the water doesn't actually naturally drain along them - it just sits there.
