Sydney roof repairs - are Google reviews reliable for finding good roofers?

The roof repair scene in Sydney (and maybe the rest of Australia) is dominated by questionable roofers.
When Google brought out its review system for businesses, we thought that it would weed out the 'BAD ACTORS" in the roofing scene.
Unfortunately, every system can be 'GAMED". And Google reviews suffer because of 'BLACK HAT' reviewers supporting the sub-par roofers.
This just makes it so much harder for the poor homeowner to separate the good from the bad. Especially on the roof - where the typical homeowner has no opportunity of any quality assurance checks.

Very true. Keep up the good work.
