GRP (God-awful Rubbish Period)

I'll start with the GRP roof but I'll dedicate this whole blog entry to which I will deem the God-awful Rubbish Period. This probably seems like I'm over exaggerating but there's just been a lot of things combined with work, personal etc and I have really been feeling the pressure.

 

Intially, as they started laying the fabric the GRP looked OK but, despite what I would say is perfect conditions for the GRP going on from what I know through reading on here we, were appalled by the quality of the work. Without bombarding this blog with pics unless you really, really want to see them, just take my word for it, it was bad! I believe I this was subcontracted but as we have not been on site I think it's been done by the builder themselves.

 

Needless to say I was not happy so met with the builder who muttered something about weather and acknowledged it was poor. There has been some improvement but I can't say I'm entirely happy but I believe this will be rectified, hopefully. I also raised the issue of the rooflight upstands not been GRPd to the roof and something is happening with lead flashing so I'm hoping that will be rectified too.

 

Here is the current GRP as it stands, comments welcome because I don't know if I'm being over picky but I want to be prepared for meeting the builder this week so please give me your opinions.

Roofing aside, thanks to the people that contributed to the thread on our ASHP and solar @PeterW and @ProDaveothers as I really feel I would have had a complete meltdown. For some reason the idea of fitting a PV immersion controller seemed to cause all sorts of issues and it's literally blown my mind trying to explain to people that should know more than me how to do it and what is needed. 

 

And my final rant, how is it despite giving delivery drivers instructions they still turn it in an articulated lorry the size of a double decker bus.... er no you will not that over a canal bridge! Took delivery of a bathroom suite after it was pump loaded over the bridge with the lorry blocking the farm who were not happy and finally unpacked it to find the whole lot was damaged. Can't get the same items now as they are out of stock but in some good fortune the bathroom company decided it was far too much hassle to collect them again so let us keep them and refund the money so we can flog them to try and pay for an alternate suite.

 

We did finally get all our 12 panel GSE 3.84kw PV system and immersion controller for under £2300 which has now been delivered which is a relief.

If the builders make as much of a dog's dinner of fitting this as they did of the GRP I'll have an absolute breakdown 🤯

The main laying up of the GRP does not look to bad, just the edges and corners that look rough.

Basically what they did was use the cut edge of the roll on the trim.  They should have used the torn edge.

It is hard to tell if the trim was properly prepared before they started as they seem to have tried to cover up mistakes with extra flowcoat.

Not a hard job to put right to be honest, just a bit time consuming and messy.

Yes and I get the feeling this will be exactly what they do again.

If they actually properly sort it and don't just but extra coats over it. Now the fascias are up I get the feeling if they can avoid doing owt they will.

First there is nothing fundamentally wrong with GRP as a technology (I say speaking as someone who sails in a 50 year old GRP sail boat)

 

The problem you have is poor workmanship. You need the contractor (the person you appointed to do the job) to sort it out.  I hope you have not paid in full for the work yet, as if not you have a lever to make them put it right, and make sure you watch what they do to "put it right"

We have month invoices from our builder and it is him we are paying for the work but we are meeting him this week so I am going to tackle this. I didn't know if I was being picky but I'll mention the edges and corners and that covering it up with extra flowcoat is not dealing with the issues. I'm not entirely sure how they will deal with the issues but I don't want to be fobbed off.

I would get the angle grinder out, sand off all the problem areas, then re-GRP those areas.

The external corners are always going to be a problem, would probably use a glass tape on them.

Thanks @SteamyTea I'll see how I get on with the builder. It's like they have ploughed on doing all the cladding knowing we.aren't happy.

As someone who has done GRP roofs myself that is shoddy work, but as @SteamyTea says it’s fixable. Another example of Some tradespeople not paying attention to detail.

You should have seen it before they rectified it. This is the fix! It's really stressing me out.

It is probably waterproof, and will stay that way, do don't get stressed about it. 

Main thing is that it is cosmetic, and fixable.

I was feeling pretty confident about speaking to the builder after comments from @joe90, @SteamyTea and @ProDave 

 

Good news, they have GRPd the roof light upstands.

 

Bad news, I just am not happy with the roof. I can't accept that this is normal even though the builder says it is and in places it looks like patchwork although he assures me it's watertight. He was talking about putting some sort of edging on it to tidy up the corners and whilst I accept these areas will always be problematic and the guttering will seem to disguise some of it but it just doesn't seem right.

More worrying is I was talking about the gully from the pitch onto the flat roof below and apparently our roof is flat "you mean there is a fall on it" I said. The response, "No, not really" 😳

I think I'm making myself quite ill obsessing over this!

 

Everything else seems to be going ok.

It might be fir him but not for most people (me included) an angle grinder and a flap wheel to take off the rough bits (as long as you don’t go right through, but even if you did it’s patchable) and a bit of topcoat will fix it.

 

flat is ok, I had a GRP roof that had a dip in it (no I didn’t do it!) and a permenant  puddle existed in wet weather but it was ok. @ProDave has an old GRP boat, they go on for many years.

 

time  to move on, no one has died, consider it a learning experience and onwards to the next hurdle 🤷‍♂️

+1 on not needing it to be 'not flat'. Many GRP roofs are fitted because of this attribute. Panic yea' not.

That's one thing off my mind then.

 

The builder knows I'm not happy and as we were walking around site he told one of the workers "she says your roof is crap" so I've made my feelings more than clear. I need to give him a chance to sort it and will follow it up with an email over the weekend. I'm not on site next week and the wife is dealing with things whilst I have a few days at my parents.

He's a bit of a cock doing that in front of you unless it was in jest?

We had this stuff done on our flat dormers. I wasn't impressed and ended up removing and leading them. Waste of time and money.

You mean not impressed with GRP generally?

 

I can only comment on pictures I've seen on here and online videos etc and compare it to the job we have had done. It can look pretty good, I guess like anything it depends on the fitting of it.

you mean you weren’t impressed with the way your roofer did it!!!, GRP can look very good if done correctly and is my choice fir flat roofs.

As far as I know, the fake stone pillars are still outside the entrance of the Heathrow Excelsior Hotel, made them in 1984 (hotel has been renamed).

@joe90 @SteamyTea 

hoping for some advice. Still no rectification to the roof as yet but after a heavy downpour today and a visit to the site I went to inspect the roof. And this is what's happening.... Clearly this needs sorting as it looks like water is already penetrating...... Any words of wisdom? Surely now I can't be told this is normal??IMG-20200924-WA0032.thumb.jpg.c040f0f1c69fce40bee1c3f6918c3185.jpg

We also have definite pooling of water, albeit we have no guttering.

The pooling is not a problem but the “delaminating” from the trim is wrong, make sure you photograph every area where this has occurred. @SteamyTea will be along in a moment to suggest it’s remedy (that the roofer should do). Don’t know if it’s luck or judgement (hopefully the latter) I have never had that happen on a roof I have done.

I know others are a fan of the old GRP. I could not live with that. I would be having that whole roof ripped off. I have built atleast 20 flat roofs, and i have never built One Flat, for the reason that, regardless of what you cover it with, it will look like yours. I am not saying that it won't be ok, but it looks dreadful. What do your drawings say ? have your drawings asked for a flat roof, or do they show a fall, constructed by perhaps firing pieces. If your drawings ask for a flat roof, then that is what you have got. If your drawings ask for a flat roof will falls, i would make him rip the whole lot off.

Thanks. I was actually having a couple of days away but my wife just sent me these. I'll get photos and get on to the builder. My patience is wearing thin!
