Mick's House Build

[samuel]

I have requested an extra 50mm length on the inner vertical side to provide a much larger catchment area.

a larger catchment area is one good point.
another important point is one that thais obviously do not know nor pay attention to:

the inner vertical side must be higher than the outer vertical side!
why? in case the gutter is full, the water must be able to escape on the outside instead of the inside. so where will the water escape? it will escape on the lower level.
if the water escapes on the inside, your roof will suffer, sooner or later.
the following 2 pics might help you to follow my argumentation:

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.

i wish you well with your house building project.
good luck.

Correct

[mickojak]

Samuel,
I think you are spot on with all you said.
It is too late for me to fix the protection sheets for me and the inner part of the gutter may still be a fraction lower than the outer edge, but if it overflows it will just run down the facia board.
The guy came and measured up this morning.
I was going to have a 5" down pipe at each end, but he has suggested two each end.
I am happy with that and gives me some confidence that he knows what he is doing.
I think it should all work well.
Time will tell.
He is coming back Wednesday to fit it.

Mick,

The guys have bought up a good question with this back section height and now provides me with some food for thought prior to ordering start of next month.
But on the other post you show 120mm at the back and 115 mm at the front so you may be OK.
Another solution for a retrofit would be to punch some holes at the best location on the front to allow some water to escape on dig downpours when it gets to deep. Just a thought and may or may not be feasible.
I know you are trying to keep this particular high use area dry.

[mickojak]

Yes, Barney,

The guys have bought up a good question with this back section heigh

All gutter is designed that way and I have always thought it strange.
What I have got is 19m of gutter collecting water from two roofs.
Hopefully, the extra height at the back and the 4, 5" down pipes will do the trick.
If not, i will use that guttering on another part of the roof and get some larger ones made.
That's really all I can do until I get i right.
Trial and error.

Sent you a PM

Barney,
Didn't get the PM for some reason?

Yes, Barney.
I've just been thinking about your place and your roof sections are very big and will have heaps of run-off.

....but if it overflows it will just run down the facia board.

ever heard of "capillary action" ?
Wikipedia

[mickojak]

Yes Samuel, I have,
But I don't think it will happen on False wood facia boards.
If it does then millions of houses around the world will be having the same problem already

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.

IT'S A ROOF!! It's designed to get wet!!

All your "protection sheets" are doing by having them on top of the roof tiles is ensuring that some water goes under the "protection sheets", between them and the roof tiles, then goes down behind your gutter or sits on the roof tiles harbouring mould. Apart from on the photo of your (?) roof where they are bridging a gap between your roof tiles and the gutter because your gutter doesn't go under the edge of your roof tiles as it should!

These "protection sheets", where fitted, are designed to go under the last row of roof tiles to protect your fascia board from overflow.

[JohnG]

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.

[BillaRickaDickay]

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?

[JohnG]

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.

[samuel]

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.
