We had a supplier a few years back on the Maejo Road (from Nong Jom) but he's not there anymore.  We have a section of roof needing replaced, so any contacts or info gratefully received.  Thanks in advance..  

There are 9,001 kinds of roof shingles.  What kind are you looking for?

Apologies, "shingles" was never in my vocabulary until I came to Thailand. 

Wooden, teak is about the sum of my understanding.  I've attached a couple of pics - a roof perspective, and the last replenishment load.  Trust and hope that helps.  Cheers.

Nice roof. 

One option is to buy some new fibre felt shingle strips from ACG which are about 750long and swap for your replacement shingles from one of the unseen valleys there.

You will get an exact match without much effort.

I see the lower shallower roof is lined with aluzinc, something i did with mine which can get noisy when it expands.
