If the aim is to protect the facia board, you do so by putting the inside edge of the gutter under the tiles, as in Kopkei's photo.
Come on, please tell me this is a wind up so you can see how many people are gullible enough to believe that these protection sheets / drips edges / drip strips go ON TOP of the roof tiles, as you've shown in your first post about this, where you somehow forgot to mention that this was a diagram and photo of the roof BEFORE THE SHINGLES / TILES WERE FITTED, rather than UNDER the bottom row as I've said repeatedly and as your videos very clearly show!!!samuel wrote:and another video showing the problem very well:
so this was my contribution to the discussion.
it's up to you how you have your gutters fittet.
but as a said before - thais don't pay much attention to drip strips - maybe due to lack of knowledge?
As your videos show, and exactly as @Kopkei has shown in the photos of his gutter, these protection sheets / drip strips / edges go UNDER THE ROOF TILES!!!! They're nothing to do with "protecting the roof from getting wet" as you said, but they're there to stop wooden fascia boards getting wet and water being drawn up into a wooden roof frame.samuel wrote:in addition to this, please make sure you will have protection sheets fixed as well. they are very important to protect your roof from getting wet, specially at times with heavy rain. these special protection sheets are often missed in thailand, but very helpful to protect your investment. see next pics.
Thais don't pay much attention to drip strips because they seldom need them: a) most roofs have a much bigger slope to them than the 1:12 or so shown in your pictures and so the tiles overhang sufficiently so that rain drips/flows straight into the gutter, b) Thais seldom use flexible asphalt shingle roofs, where drips strips are needed due to to the flexibility of the shingles which you don't have with tiles, and c) the guttering is usually designed to cover the fascia board up to the tiles, with little or no gap so that wind can only blow the rain back onto the gutter not onto the fascia board.
Where there is a need for a drip strip to protect the fascia or cover any gap, any decent Thai guttering fitter will fit drip strips or modify the gutter, exactly as they have done with @Kopkei's.
I'm still not sure if you're winding people up and trying to see how many people will be gullible / stupid enough to believe that drip strips / protection sheets go on top of the tiles and are to "protect the roof from getting wet", if you genuinely believe that they go on top and you simply haven't looked at the videos you've taken the trouble to link to, or if you simply haven't noticed that what you have posted is wildly misleading even though I've repeatedly pointed out that they go under the tiles rather than on top where it will have an adverse effect.
Either way, you've shown that some people here will believe anything, even putting something on top of their roof tiles to "protect the roof from getting wet"!!! I wouldn't have believed that was possible unless I'd seen it here, so thank you for that!
