I've got an extension area comprising a car port, laundry, pool machine room and a small workshop, all encompassed in a structure with a flat roof. And it's leaking, not a lot but there's lighting and electrical outlets so I need to get it fixed.

 

Can anyone recommend a good roof coating that would be available in TH - or a reliable company that can fix the problem without exorbitant skin tax? (E. Pattaya area).

 

 

What is your flat roof made from? 

 When rain falls on a roof, it needs to drain off somewhere. 

Is the roof holding water? 

If so, then applying any kind of sealant would be useless. 

You need to check that any rainfall has an unblocked outlet, and that water isn't sitting up there. 

If it is, then that would more than likely be your problem. 

Flat roofs are a nightmare do you use the flat roof area, if not over roof it.

It's a concrete structure.  Water is pooling on the top side surface so this is bound to be the issue; there's a definite puddle that forms after rainfall and there's accumulated sediment around it.

 

I've since contacted the builder and they're going to take a look next week.

 

Thanks everyone.
