no, that's the problem. we're looking to replace all the flat roof section, retile the tiled areas, new soakers and felt the concrete bit in the corner. I was wondering if it's worth the additional £280 to use triflex rather than torched felt on the flat roof area. Torched felt to my untrained eye looks a bit like the budget and shit option. Is that the case, or is it the go to option for this sort of thing? thanks very much

Ah, not sure then. Looks like mastic asphalt is on there now. There is a two layer and three layer torch on felt, with the three layer having a longer expected life, but different brands give varying quality and life expectancy.. Any particular reason that EDPM or the grp resins aren't being offered as I though that would be easier/cheaper as less time and skill to cover a small area.
EDIT: Currently working on a listed building and the roof replacement we are looking at EDPM and or grp resins. But so far we are 5 years in and still fund raising.

It all depends on what guarantee is offered with the two systems. Torch on if installed properly is a cost effective way to do a flat roof that can be easily repaired down the line. The best roofer I know prefers torch on systems to GRP / EDPM, the latter has a longer life expectancy but this is unproven as they have not been widely available for as long as the claimed life expectancy so any claims are based on lab tests.
One thing I would say about the roof pictured is it has clearly been patched many times in the past. Take any quote you get with a pinch of salt, simply put it is impossible to know the condition of the roof structure under the tiles and felt until everything has been lifted. You may get lucky but I'd be surprised if you didn't have to do some form of repairs to the structure. Plan for the worst, hope for the best.

Do you know where the leak is?
Those waterproof roof coatings work, was used on a temporary repair on a really poor roof till funding was in place. So far lasted five years and the funding isn't in place.
EDIT: Thompson roof seal, the 10 year guarantee one.
