Want to find a good and reliable roof contractor around Kepong/KL area.

Having some water leak during heavy rains. Personally went up to the roof and attic to check but no visible crack. Judging from leak area and pattern, most likely water sipping from wall and drainage gutter instead of roof tiles itself.

Anyone have any good recommendations? Would like to see my options before I go back to my original roof contractor which was 6 years ago..
