I did correct it in a later post that it is inland. The beach front is 4 rai and 450 million. Out of OP range i think. C_lliers is the agent.

Thanks – and sorry I did not notice your correction post, just under it – presume I was too interested in quickly buying the 2 rai beachfront land for 7.9 million baht and resell for a minor fortune...????

So the 100% waterproof solution the galvanised with insulation? I think this is how they make in EU.

 

Well you do have options here.............

 

There is a type of waterproof "paper" which can be laid under the tiles, just the same as it can be under a galvanised roof, or there is the foam spray type insulation which also helps to keep out the bugs.

 

I do like the look of expertly tiled roofs, although I come from New Zealand where galvanised steel roofs are very often the norm!! However if I was building my own house here, depending upon the type and construction, I would choose a roof to suit, either of which would have some form of insulation under it.

 

Seems ambiguous I know, but some form of insulation under both roofs is really a must, in my opinion.

 

PS. The waterproof "paper" that I have seen used, does tend to disintegrate with heat, over time.

Now that is excellent advice, because I lived in two houses where the roof was of substandard construction with tiles simply laid on a basic steel construction and it was not satisfactory at all.

 

This especially in the wet weather when the wind was blowing because it would blow rain under the tiles and the leaks would show in the ceilings of the rooms below. Furthermore they are apt to move because they are simply fixed by their own grooved pattern with the occasional piece of wire or suchlike.

 

A professional job with a galvanised steel roof won't have those problems provided the fixings are of the correct type and not just nails. Or as Khun Per has suggested, some form of waterproof/insulation below the tiles if you are going to use them, which can also help with keeping out the heat as well as waterproofing.

SCG – i.e. HomeMart – has a roof center that will make detailed drawings, and give free quotes for various types of roof tiles, for a total roof construction, including the use og galvanized steel instead of normal steel. In my case, it was cheaper labor costs than using our building constructors normal work team, and he was kind enough to accept me choosing SCG for that specific job. SCG have travelling expert teams that will come and do the job, and give you a five year written warranty; which I presume is worth a lot more, than any promise from a local bulding constructor that one cannot find next year, when the roof is leaking – I've heard that tale more than once.

 

Water protection and heat insulation are two different membranes. Galvanized steel has less weight, as thinner steel profiles can be used due to rust-elimination.

 

In my case SCG Roof Service representatives came once a year for five years to check, that the roof was still satisfactory, and we haven't observed any faults – i.e. water leaks – after nine years, including beachfront monsoon storms, it's still in perfect condition...????

OMG - I've heard that you can lead a horse to water, but not make him drink. In this case despite many experienced people trying to drag the horse away from a poisoned well, this horse is determined to stay and drink til it's dead. So in 2 to 3 years time you expect to inherit some money (I say this as you aren't displaying the aptitude that would suggest you are a retainer of money). Here's some free advice, when you get your money invest it in property. Invest it somewhere like your home country where it has a good chance of appreciating in value and should the need ever arise you can sell it when and if you want to. Treat Thailand for what it is, a holiday destination, stay in hotels and rent. Everyone is telling you this, try listening.

If you just want a weekend retreat, rent. Far less risk.

Agree in that. Having a house also mean maintenance, and if you don't live there, you might need someone to look after the house.

 

If your are dreaming about a week-end retreat in paradise, rent – and that can include fully serviced – it might be much cheaper than buying land, and build something. Think of buying a sea-view land-plot for 4+ million baht – or beachfront for a lot more – on one the popular resort islands; and build a dream house for another 5 million baht or more; and a little bit of this-and-that and some furniture etc. inside the house; you end up in the area of 10 million baht. That's about 300,000 baht a year just in plain dividend, if you instead invest the 10 million baht. You're having travelling expenses and living costs anyway, so you have 300,000+ baht a year to rent something that might even be more outstanding than what you can buy for 10 million baht. Furthermore, if you wish to stay at a different location, or on another island, you're free to choose...????

The water-protection used by SCG on my roof was a thick coated alu-foil, placed under the roof battens at the ends, where rain would find it's way in (in photo, the blueish foil under the tiles) – mind that in wind gusts the rain don't come straight down from the sky – right underneath the tiles were placed a reflecting foil for heat insulation (slightly visible at photo).

 

I am sure this OP must be on the long run troll with this post.
