hey there, I'm sure you have solved your issue by now, but since you posted this i had a similar case like yours a couple of months back, and regardless of the roof you choose its really up to you all of its pros an cons, of course on top of all is the cost la.

i think the most important thing is to consider the long term expectations you have, as you know metal roofing vs clay only has one issue. the Sound it makes when it rains, and heat absorption during mid day sun, but if you have decided to use metal roofing, there are ways to make it sound proof, and more resistant to building up heat, my Uncle Mr Teh ( contact below ) can quote and do this for you.

But if you or anyone, ever face this same issue again you can call my uncle Mr Teh 012-6721130 .can Call /wassap

I recently also launched his website at https://mrfix-leaking-roof.com/ been around for the last 15years, if anyone can stop your leaks or give you the best price for metal or clay roofing its him ! Hahah support yah! thankx
