This video shows the repair and re-coating in grey of a fibreglass roof in London. A section of the fibreglass has delaminated due to a fault in the original installation. As a result the top coat also failed in places. The fibreglass was repaired and the top gel coat reapplied. Enjoy.

Great Job, are you based in London? Could you quote me to fix my fibreglass roof please?
Hi yes I’m based in London. No problem, you can Whatsapp or call me on 07580512409
How long did you have your fiberglass roof before it needed repair?
@@uittyman a year - these guys did a great job. You should try them out.
PPE where the mask at bro. You’ll regret that in years to come. Get a mask. Worth the money
If you did a job like that up north with car repair kits and diy gear, you would starve. I got the impression this is your first time with grp. Try reading the book again specially the technical bits about "CLEANING" MIXING" and "LAYING UP" and how to do it correctly. I'm sure in time with a bit practice you could get it right.
I have been doing this for a very long time with flat and pent roofs, also repairing sea going fishing boats. I do have an idea how it's done.
Hi guys thanks for your comments.

I'm just wondering why doing fiberglass just the edges supposed to be the whole thing whole roof
If that rood does not peel within in a year or two id be stunned. Never seen GRP roofers work in this way. Not enough tacks in trim, not enough resin used, didnt notice a paddle roller, no additional coat or two of resin before top coat applied i could go on
There’s a lot these videos don’t show. Bare in mind most are time lapses and edited down. Many other videos showing more steps. One to be uploaded later today. Thanks for watching.
Great video, difficult to find quality videos on fibreglass roofs. I now feel confident in giving it a go. Thanks a lot.
Could a commercial jet washer be used instead of the scrubbing and wiping with acetone?
Yes that could be used but I would still clean with acetone also
Got to say that patch repair had no where near enough resin underneath or ontop?? The rest looked ok tho 👍
Could of found a smaller brush lol
Looking at what your chipping off......... apart from the edges of about 6 inches up to the roof edge. That looks far too thin, there can’t be any fibreglass mat on that roof, it looks like the centre of that roof only has topcoat straight onto the plywood. (You weren’t chipping up fibreglass mat-were you) ? Or is it possibly 1 layer of 1 oz mat. Very odd.
What the hell are you using to laminate the fibreglass mat on the edge trim ?
Goggles every time measuring and mixing the Catalyst.
Sorry to say it, but just putting another thin coat of float-coat over the whole roof will not fix that roof problem.
A waste of time and someone’s money.
Don’t be too quick to judge the thickness of.a product from a TH-cam video. The roof does have fibreglass mat. My job was just to reapply a top coat (uv gel).
The fibreglass Mat underneath was fine except that small area on the front.
@@darrenthebuilder ............... it did look very thin
Tbh it wasn’t a good job. I just did an inexpensive repair for a friend. The rest seemed sound anyway and wasn’t pinholed
@@darrenthebuilder your friend was lucky to have you around, but I don’t think you’ve solved the problem with a small repair and another thin coat of float coat.
Did you do the original fibreglass roof?
what's the difference between the resin and the top coat? If you have pinholes would the top coat fix that .. Some good videos. Keep them coming.
Hi the resin is the most important part. It’s what creates the waterproof barrier. Pin holes won’t be solved by the top coat. If you’ve got pin holes it may be better to sand them down and apply a think resin to fill the holes.
Total amateur job..
Coating was very thin?
You are a very hard work
Thankyou
Looks good ! I reckon a floor sander would’ve been easier?
Good Joob!)
This is a guy who thinks he’s a fibreglass roofer
Hi 👋 could you let me know where based please?
That's a excellent job, I have a flat roof that needs repairing in Manchester like that , looking for someone who can repair it like this, as had lots of cowboy roofers who don't understand fibreglass, can you recommend anyone?
Thanks, unfortunately i dont know anyone in manchester
It’s true. People come over and say you need to replace whole roof
By looks of roof it was a ply base substructure which fiberglass is not happy to adhere to unless sanded before fiberglassing and also if damp it will also not adhere to , OSB 3 is best for the roof decking. Also you did not put fiberglass matting over places where you scrapped off the smaller areas where it had delaminated which you should have before using the gel coat on top.
I didn’t construct the original roof. The other areas scraped was only gel coat and hadn’t delaminated
@@darrenthebuilder I did realise you were only repairing the roof but this is a common fault were people use ply . Ply need to to be well sanded before applying GRP as it will delaminate as this roof is doing , OSB3 is far better . You did leave patches that you should of keyed back and applied CSM then topcoat over as will fail later .
Yes @darren, - I would have sanded all the bare bits & applied more matting- even though the CSM was still intact in those places-- however I'm fussy & never want to be called back & realise it was my fault 😅-- & have to charge accordingly -- it all depends on how much ££'s was negotiated with the customer as to how much they wanted to spend on a repair --- it may be effective to do it well, like he did it, as quickly as possible, & factor in to the client to call him back in a 2-3 of years to sand & apply another top coat!-- what do you think?
Really nice job. This will help our repair. 🙏🏾
Omg that is nightmare finish, and why not nail trim ? Was leak coz not enough nails and no glue under , and you put mesh and hold by hand ? That will do ? After half year will leak again, and finish top coat is really bad
Well it’s been 3 years and it’s fine so your obviously wrong. Thanks for watching
Bro you need to post more often you’ll definitely gain followers your work is amazing good to see a brotha doing it shout out for Australia
Thanks for your feedback bro. I’m definitely going to be posting more regularly.
very well demonstrated
I have peeling in a small area, could I not do a patch repair? Also, would isopropyl alcohol be a suitable alternative to acetone?
Hi yes you can patch repair. The alcohol should also work to clean
Great video how many coats would you put on a boat Hull and do you do boat hulls thanks again
This is a job welll done. I also have an issue with my fibre glass roof, of course it’s leaking. Lol. Would you be able to give us a quote. Many thx. 😀
Hey Thanks, sure send me a message to 07580512409 Thanks
I’m not sure who has taught you this but , where the gel coat had lifted fron trim where you did repair the raised trim was not nailed down properly , the gelcoat you fibreglass repaired onto was not power sanded what won’t last more than a year , the roof needs to be power Sanding back to fibreglass even then I would re fibreglass all roof , rubbing a-bit of acetone on gel does nothing I can assure you, fibreglass roofs don’t peel the gel because they not been sanded , soon as the styrene has released from fibreglass roof and Are fully cured it can be gelcoat we sand them to take off burrs and and rough edges , I will assure the roof you repaired in years to come will look alot worse than It did before you started it 😂😂 hope you take my advice on board it’s not a dig at you if you even need help or advice message me
It said he sanded the whole roof. It wasn’t because of the raised trim, it was because of the poor prep prior to him repairing it. No adhesion to the substrate.
Or better still,use a 3 layer torchon system.
Wtf have I just watched
How did it get damaged.?
I gotta repair a fiberglass roof that has black volcanic sand on it, any tips buddy.
Great content 👍👍
Hi there, not really sure. Is it’s felt?
@@darrenthebuilder No!
It's like that sharp black fish tank sand lol looks sprinkled on before it's go off.
Client was happy with it just plain for now so long as it's water proof!
Mute guy
how money much ?
Job well done but you could lose your life with no mansafe line or edge protection.
Hi nice repair
I tried to repair my fibreglass roof last year but now the gray top coating is pelting off I sanded everything down just like you do
Can you give every advice please
Blus up 👍
You need to sand all of the top coat off ! Not like he has done this is wrong , it will peal off again - use a belt sander not a orbital one
Cure it’s manual states that you can clean, abrade and recast topcoats. Abrade means to key. There is no requirement to sand back to the laminate and it’s impossible with out removing some of the laminate itself, therefore weakening the roof and possible revealing pinholes.
Peeling usually occurs when the topcoat is applied too thick.
Also you must clean the roof with acetone after sanding to remove contaminants 👍🏾
@@darrenthebuilder
All right pardy nice 👍👍👍
Hope you are well insured , as a long drop off that roof if you forget where you are working , which is easy done and slip off that roof .
Insurance won't save your life - a bit like fisherman in small boats will always tell you, just don't fall in.
Is this roof leaking?
No
@@darrenthebuilder Why is it being repaired then?
@@MrFlatroofer it was delaminating in an area and they asked me to repaint the roof
Can you give it 2 coats
Yes you can but normally one is sufficient.
Really a fantastic job!
Thanks
That one sheet of sandpaper won’t last to do that whole roof
The paper was changed multiple times. Thanks for watching and your comment!
Again AMAZING 👍👍👍
Thank you so much 😀
I like fiber glass roofing , it will last forever and strong perfect and nice job .
