Hi.. I am new to this forum. Was struggling online for help and came across this forum. Will be thankful if guys can give expert opinion on my issue:

I had rear extension done of my house about 10 months before. Flat roof (fibre glass) extension about 50 SQM. I already have a leak through this new roof. I went on the roof and noticed below issues:

1. Layer of raisin used is not thick enough
2. Splinters of boards underneath grey paint/raisin are visible i think due to extreme heat earlier this week, at so many spots splinters have expanded and came out on top of the grey raisin/paint.
3. Roof has no slope/fall at all and water is settling at different places on roof in small ponds.

First two of above issues can be resolved by applying a new coat of raisin but the biggest issue i am facing is that roof has no slope/fall at all. My understanding is, doesn't matter how many coats of raisin apply, settled water will eventually cause damage to roof sooner or later.

Is there any solution to make a slope on the roof (without ripping the whole surface)?
OR I am worrying needlessly. I mean if thick layer of raisin is applied thoroughly on the whole roof then even small water settlement will not damage anything?

Contractor who built the extension is willing to do another coat on top the roof but is not willing to redo the whole roof.

I wait for your valuable inputs. Thanks in advance :)

You can't create a fall in coats of resin.

Unless the contractor is prepared to replace the deck and create a fall and then resurface the roof, at no cost, then the best option may be to leave it and wait for the time when it needs replacing. Whilst it is true that the performance and lifetime is potentially reduced, you should still get many years out of it. Another resin coat may not necessarily be of any use, as the whole lot will degrade as one.

But ultimately, if the contractor has not done the work properly, ie not created a suitable fall, then he is negligent and a court claim for your losses (ie refund and cost of replacement) would succeed if that is what you are minded to do.
 
This is the posters roof (from another forum) hard to believe a roofer done this.

By the look at that picture, it looks like court action is required.

Thank you all for your valuable inputs. Your inputs told me where exactly I stand and gave me confidence and grounds to talk with the builder. He is willing to redo the whole roof at the end of this week. I will keep you guys updated. Thank you all again.
