Wife bought a house in her sisters subdivision. House sat for 10 years empty. Has a flat roof over the carport, and that is also next to a pitched tile roof that sits over the front patio.

Property had trees in the yard that dropped leaves and fruit on the roof and it was so thick it blockes the 4 flat roof "drains".

Finally got up there yesterday to pressurewash the roof. Oh dear, I died inside when I saw what we are left with.

Here are some photos. Looking for some general advice and maybe just a couple of words of encouragement. The cumulitive damage is looking pretty expensive to rectify, especially as I wouldn't feel comfortable with the Thai "it's good enough" attitude so prevalent in our area whrn it comes to contractors....

Close up of some seams in the concrete that look bad

Some photos from the ground looking at the patio and carport ceiling...

Over the patio it appears to be gypsum board drywall, easily tore out and replaced. The carport on the other hand, appears to be the same concrete as the flatroof.

I could only pressurewash the flat roof so much, i would say about 10% of it is covered up by the hangover from the front patios tile roof. So i still have to figure out how I'm gonna get to that section of the roof for repairs, I may end up tearing out the drywalled patio and going from underneath, that's where appears most the water damage is anyhow.

Thanks for the time if anyone with any general knowledge pitches in...

I've sent the photos to a roofing friend back in the States, can't wait to hear what he has to say🤣

Lick of paint will fix that for another 10years.

I'm not clear what the big deal is. Patch the bigger holes with mortar and lay down some roof-coat.

Do not try to patch a roof from the bottom.

Looks about right for an unattended Thai roof, as per previous post - lick of paint and she'll be ok.

Clean the roof as well as possible loose chips and paint and whatever. Then apply this stuff once the roof is completely dry…

Thanks everyone. Will update as things progress. We have plenty of time, just not plenty of funds atm😅

Mortar is cheap, as is a hammer, chisel, scraper, wire brush, a bucket and a trowel .

Just my view - but I'd try to add a gutter to take the water from the pitched roof tiles and let it drain away from the flat roof. That'll reduce the water pressure on the flat roof and give a good coat roof seal on the flat section a fighting chance.
