In case you can't see the difference, have a look at Kopkei's picture where the inner edge of the guttering is fitted as it should be - under the last row of tiles.

Every country has its own building regs, some good, some not so, I've never seen these roof protection sheets in use in the UK, although my building projects were some 20 odd years ago so things may have moved on. Looking at the diagrams, the protection sheets are being used on low pitched roof structures and I would suggest so low that concrete tiles would not be used. I can see why on a slow draining low pitched roof these would be of use to prevent water seeping back due to capillary attraction. Most Thai houses I see are usually pitched between 30 and 45 degrees. Why would you want to protect your facia boards any way as I think most people by now are using non perishable materials, In Thailand no boarding is used under the tiles so what part of the roof are we trying to protect?

They're absurd. Why "protect" just the bottom few rows? Why not all the tiles over the whole roof? ... and what about protecting the protection?

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.

This has got to be a wind-up to see who falls for it.

So, JohnG, looks like you're up to some creative editing on this thread.

....just to underline why protection sheets (drip strips or drip edges) are needed.

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?

Not playing a game at all - simply guilty of trying to quote part of a post using a mobile rather than a laptop, which is extremely difficult here for some reason, then being unable to edit it later to correct the mistake as there is some sort of time limit on edits making correcting it later impossible.

Obviously the quoted part was from @samuel, not from you. I would have thought that was patently obvious and that anyone who can spell IQ would have seen that straightaway.

The whole issue of "protection sheets" which are now "drip strips" is obviously from @samuel.

If you want an apology for making a mistake that may have led someone with the intelligence of an over-ripe banana to think I was trying for some bizarre reason to make it look as if the protection strips / drip strips were your idea, rather than @samuel's, then I apologise unreservedly, but I never thought anyone here would be quite that stupid.

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!!!

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.

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!

So to sum up, "Drip Strips" are useful when it comes to bodging up leaky roofs caused by poor design, old age or bad construction practice such as low pitched roofs, insufficient tile overhang into to the gutters and/or lack of Soffits.
Obviously not the case in Micks Construction as its a new build, has a typical Thai pitched roof a good tile overhang into the gutters and Soffits of adequate dimensions.
Too much knowledge can sometimes throw spanners in the works. PS never trust Promotional Video's...........
IMO.

I think it's fair to say the facia boards in most homes in Thailand today, probably for the past 10ish years, are cement board (Serpa, Chang, etc). They don't rot.

Ok, Back to business
The sheetmetal crew came around and fitted my gutters today.
Done a pretty good job too.
They constructed them just as planned.
Highest point of gutter is in the middle of the centre, straight section, sloping down to the two inner corners, then sloping further towards the end of the roof and down pipes, perfect.
Plenty of brackets too.
Only two small problems, misunderstanding/confusion as usual.
1: I requested 125mm down pipes, he came out with two 90mm down pipes. He agreed to make two more on the job, so now I have two 90mm down pipes at each end. Hopefully will be enough to get rid of the water fast enough.
2: The quote of 8ooBht p/m was for their standard gutter, so all cost 1000Bht p/m, fitted with extra brackets and the new design.
So, time will test it out from now on.
Fingers crossed.

Mick, looking at the size of roof which is actually feeding the gutters you shouldn't have a problem.

Just out of interest, is the rest of the roof unguttered, and where will your down pipes lead to?


The only rrason I ask is if the pipes don't actually lead to a drain off you don't have a problem - you could just leave the ends open, or cut the ends down slightly so that in the event of an overflow it will be at the ends rather than anywhere else.

John,
Rest of the house in un-guttered at present.
Truth is, I have not really decided on what else exactly I am going to do yet.
I need to decide where the rain water tank will go and how much of roof to drain into it and also where to send all the other run-off water..

I am really just wanting to get to lock-up, (which is done), get kitchen built etc, so we can move in if we want.

The rest will happen over time as work will dictate my timef rames.
No hurry for me, just be really happy when the bulk of the build is finished.
Mick

no matter what kind of roof you have, they are very useful at gutters.
kind regards from a ex-professional plumber ...... me.
have a nice day and feel free to make it different.

Looks like a great house. I'll have to find this interesting thread again on the desktop instead of the phone (which will now be easier once I send this note.)

One thought now that I've looked at your plans (I know it's a bit late, but maybe not too late).

Your kitchen area, and more importantly your cooking area, is right in the middle of the house between bedrooms and living area. Even if a lot of your cooking is done outside unless you're only into salads and meusli it may make the house smell. One option which could be done now before everything's finished would be to put plumbing and wiring into your #4 bedroom so it could be easily changed to a kitchen, with outside walls, extractors, etc IF you need it later.

If you don't need it so much the better, but it may be easier to do something about it now than later
