ive had a few quotes (excuse my lack of information as it is a bit confusing to me what APEX, valley, channel, the box) and other things that were mentioned.


i had one for £750  (i was told the membrane needs to replacing under the tiles etc and its leaking behind the wall)

another quote was for £1500-2000, i sent a pic on whatsapp and was told where i have the trianlge above the window all that needs changing re channeling ... and re-doing etc 

Frustrating to have such conflicting advice.
Solution - get more quotes!
But make sure each one actually looks at the area, and can point out what the cause is.
Yes, there's a sheet - 'felt', underlay, membrane - under the tiles, and that acts as a secondary barrier to failed tiles and stuff. It also helps guard against air pressure lift against the tiles.
But, it ain't essential. The outer roof covering - slates or tiles - do the weatherproofing bit, so a failed membrane should not let water through.
I'd want photographic evidence of the cause, before handing over the contract.
If that is the cause, I'd at least want solid trays along there, under the felt.
But, evidence still required.

I had another quote, this time the gentleman got his ladder and went up
he took a few videos and showed me, he said a tile was out of place and he put it back in
he also said the lining is rotted and crumbling and showed me a clip of him using his finger to take bits out. he said water is getting in through there

he said he would need to cement/seal both sides of the lining again and he quoted £350.00


the fact this roofer went had a look and took a few videos and showed me did give me confidence over others.

A misplaced tile will clearly let water through, and if the membrane underneath is tatty, that second protection could also fail. That all makes sense.
Not sure what 'cementing' of the 'lining' means, tho'. 
Do you have sight of the pics?

Do you know where the roof titles meet the apex section, there is a like a ‘cement line’ seal in a straight line , and there are smaller titles between this and another ‘cement line ‘ which leads to the apex triangle section of my roof

he was saying that needs re-doing as it’s rotten and crumbling and water is likely getting through there too 

I will have to take picture tomorow and post and hopefully it will make sense 

please bear with me and I appreciate your help

That guy sounds like a keeper

Bothered enough to get up and look in his own time and take pics for you.

Plus the price sounds reasonable
