I guess it all depends on if you can find the root cause and have the right contractor to fix it?!

My case was also similar to yours, but mine is a roof tiles. Last 7 years was hell, we cant even leave the house for vacation in peace. It pretty much leaks at multiple places, and the span of 7 years, easily would have called 7-8 contractor to fix and cash spent! was just wasted.

Finally found the contractor that mentioned above, via a relative of mine, who did his house 1 year ago.

Last 2 months, expecially during this rainy period, was/is the most peaceful time of our life!

Mine cost about 15k.
