"Eave trays should be fitted under the felt as they are designed as felt support trays for the fact over time the ends of the felt deteriorate so you need the eave trays to support the ends of the felt to stop it sagging inside the soffit and in future causing a leak."

"Hi Lesley.
Yes the eave trays need to be installed underneath the felt unfortunately.
If you would like to give me a call for some further advice please feel free.
Kind regards

"Ideally the eve trays should be fitted under any existing felt, as a way of ensuring any water entering the roof does not run under the trays."

"No, he is right to put nails in your eaves as it makes the roof even stronger and the tiles can't come loose."

"B) If there on top of the felt then it's pointless having them because the water will still run under it they need to be under the felt so the water can run don't need scaffolding and it would probably take 30 mins per side"

"They need to be fitted under the felt to make sure it doesn't cause a pocket where the water can get underneath and cause leaks or damp"

"If eps trays have been fixed on top of the felt then yes it can cause problems as the eps trays should be fitted underneath the felt as there there to prevent the felt from sagging and it gives you that extra protection as they should finish into the gutter. Yes they can be taken off and re fitted at a low cost as you can re use as long as you don’t damage them when taking them off. As for scaffold that’s down to the tradesman and whether he feels comfortable working off a ladder."

"The eaves trays should definitely always bit fitted under the felt or the water will run beneath them defeating the object of them. Extra scaffold price depends on the height of the building.
