The reliable way to hire a tradesperson

I've had a warm flat roof repaired with new boards and felt as the previous job 4 years ago was a botched job and I had leaks. The job now looks good with properly joined felt and finished properly at edges and into the gutter. However, we had rain last night and three quarters of the roof has water pooling on the roof (total roof approx 5m x 4m). I suspect there is no fall. Can anything be done now to rectify?

Water collects on the flat roof of my outhouse when it rains. I now notice staining on the ceiling. What is the best way to repair this? The roof is about 10 years old.

I need to get a small flat roof above a window replaced (only 2.5 squared meters). Current cover is in felt but several roofers advised using fibreglass (GRP) for the replacement as it’s more durable. I’ve read that fibreglass roofs often make loud cracking / popping sounds due to thermal expansion, which could be a real noise nuisance. Is that correct? The roofers said it shouldn’t make any noise.
