Is this GRP roof being done correctly?

[ERICAB]

Thanks cotswoldbuilders - you predicted correctedly.

Also mentioned previously was that the works were undertaken during period of rain. I called the builder prior to the work starting to ask him how he intended to go about it given rain forecast and he assured me it would all be weather proofed without problems. But it wasnt the case.

He laid the cheap plys down (nailing through the old felt roof) and put down the first layer of resin. He left all the edges of the roof exposed without any weather proofing and left it when it rained the whole night and some part of the following day. 48 hrs after the first layer of resin went down he coated with the second resin.

Day 3-4 days following the night of rain, water has come through the inside of the ceiling in a bad way! Dripping through the plasterboard and through the downlighter holes. It is worse that before I had the roofer in!

I called the roofer and he said its a minor problem. He said it would have happened anyway over time given there's no insulation and there will be condensation. He now cut a hole in the GRP roof and put a vent in?!? Any views on whether this will resolve the major leak I'm having? and whether this makes my roof any better?

My question is - how can he make the roof better, short of stripping it all off and doing it all again which he has sworn he won't be doing? What actions shall I take?

29.10.24. Hants UK. DIY NOT. REPLY TO MANEATCHICKEN. This looks like a terrible situation and these roof issues are very distressing. If we could help we would but are in dire circumstances ourselves. We have had 8 different people round here to look at this lean to roof which was capped by 10mm polycarb multiwall fitted the wrong way round and none of the sheets were fixed to each other, they were glued. The sheets are full of water which has no way of draining. They are huge sheets with no way of expanding so huge bows are present. When I was very ill someone put 40 bricks and bits of concrete on the sheets which did still more damage. I found a lot of my tools and equipt were damaged by water so the situation is devastating. We have moved all tools etc into the main bungalow and we can hardly get into the kitchen,bathroom,sitting room. The lean to is fixed to side wall of bungalow and is about 40ft long x6ft wide. The rafters are fixed to the facia of the Bangalow and have inadequete slope. Theres no wall plate,the rafters just lay on the 4.5 inch bricks. The 8 people who looked at it seemed to want to make their first millions and in no way wouild we trust them. One person however has been round to discuss the issue and even put an estimate on the net but theres hardly any details about what they intend to do, how can they expect us to approve the work? He said he would do the work in Nov 2024, just imagine the risk of doing that. Crazy. Do you realise the difference tween an estimate and a quote.No materials are listed and no metion of what thickness PC would be used either. Would his wife go and pay £60 quid to a hairdresser not knowing what they would do. He lives i a two room flat. A 'friend' brought round a young bloke who works for a firm but does moonlighting, he quoted £200 just to drape a tarp over the problem. He is using his firms van. So £200 for about three hours work adds up to about £500 a day wages with no tax or overheads. Thats about £2500 a week. I think its time for me to start a tarp draping firm and get myself a mansion and a Rolls Royce. I wish I was just starting out in life because I would undercut these characters by about 60% and would have 1000s clients. I reckon its time we had a dose of unemployment. In our case we were tricked by sellers,agents,surveyor and it took us 10 yrs to realise that this building is full of bodging that tw teachers signed chqs for. God help the UK. We are working 7 days a week 12 hours a day whilst ill. Now someone has been rounde here explaining all about will/trusts scams This is the second build crisis in our lives, the one before the present involved the builder going to Court. We had no sewage/water/elect/door/window, then all our tools were stolen and I got Legionairs. DOES NO ONE CARE?? This is not the whole story re what we know, its on 40 hard drives.

We currently have an old Felt roof on our house which is dipping in places and decided to replace the roof with a GRP roof. We hired a roofer/builder who quoted to strip existing felt, re-fir, re-deck, and install GRP system to the entire flats roof.

When looking at the work done so far, I noticed the following:
1) The old felt was not completely removed but the firring/plywood was laid on top of the old felt (builder claims he removed the top layer)
2) We agreed to lay new firrings, the builder said the laid 4 inch of fall over approximately 10 meters (length of roof). Is this sufficient?
3) The plywood looks like ordinary plywood rather than Weather proof plywood or OSB - can this cause any issues with movement/moisture?
4) There is a noticeable dip in the middle of the roof which looks like there will be some puddling ... Is this normal/acceptable or can I assume there will be problems in the future?

Any thoughts? The builder has so far completed the decking and the first layer of resin...
