I did this last year. May I suggest a hoover before sweeping off the dust. It's fast and keeps everything clean. I still brushed afterwards but doing the hoovering first stopped me dumping dust into the air for people to breath or my neighbour to see on their roof. Your end result is great. I am disappointed in the original person who laid it because they seem to have made quite a few unnecessary joins in the fibreglass. They also failed to feather the edges to remove the lines where the sheets join.
Hiya, Amazing video with lots of information. Thank you. I have a coated fibre glass roof, which hasn't been maintained for about 20 years. It's not leaking but I want to restore it to prolong it's life before it does start to leak.. I am getting conflicting info from companies. Some say use acropol some say don't, some say cromopol and acropol would peel off after a couple of years because of the old coating etc. I am so confused. Can you help please? Thnx
Is there a good product that lasts you could paint over this type of roof ? Ive had a room added with this roof and has leaked from day one builders gone and im out of large amounts of money to have it taken off really is there any advice ? Many thanks in advance.
I have done over 10 thousand fibreglass roofs and u should never do this clean sand acetone then you need to mat the roof then the top coat doing what he done will start to peel off I see this all the time to many roofers doing fibreglass who don't know what they are doing I started work building fibreglass boats I'm 1976
Hi. I used Res Tec GRP 505 topcoat but I wouldn't get too hung up about the brand. Go to your builder's merchant and ask for topcoat for a grp/fibre glass roof. BTW, topcoat and resin are two different things. Resin is applied first and topcoat is applied second, on top of the resin. In my video I only apply topcoat because it had worn with time. I just wanted to explain that in case you weren't aware. And topcoat isn't cheap! Expect to pay about £80 for a 20kg tub. Take care
@@Mezquita100 I have lots of pin holes and fiber glass that wasn't properly soaked with resin. Would you suggest putting additional layer of resin and glass fiber matt?
@@MrFlatroofer there is no felt flat 30 years old that hasnt had multiple repairs(mostly by cowboys) and leaks,if felt was better we'd still be doing it(no body was burnt alive or no house was burnt down in the making of this video)😁
@@robertodonoghue4490 I pass a roof many times that I renewed 27 yeas ago and not leaking. All the professional roofers where I live all use a 3 layer torchon system. (SBS Polyester).The GRP and rubber roofs were introduced for unskilled roofers. I have visited over 80 GRP roofs that were leaking. The felt you refer to is the old Glass and rag felt that has not been used for over 35 years since the Poly/SBS was introduced. If you wanted I could (along with many other flat roofers) construct a flat roof that would last over a 100 years and still cheaper than GRP. Not practical though. One prominent contributor to these blogs, no longer uses GRP. he was big enough to admit GRP is not suitable for flat roofing. I note your remark about fire though. Good point Sir. That is another reason why many roofers are turning to GRP and rubber, much to their disgust.

Or you could just buy some aquashield flat roof paint. Just sweep the roof and paint on. No fuss.
how much you would charge for a square meter similar structure roof?
Fantastic

Hi New Polyester Topcoat ,Key it back and apply

Presumably the recoating would be covered by the guarantee.

What step did he miss? Mat the roof? Does that mean to wipe off the acetone?
So you re fibre glass the roof then apply top coat lewis ?
So you need to re fibre glass the roof after acetone lewis then apply top coat again
Excellent demo many thanks for sharing.
Hi
Which top coat resin did you used
Thanks 😊

Hi
Thanks for your reply and information about the topcoat
Thanks again
@@Mezquita100 would this top coat fix pin holes common with fibre glass. Nice vids
@@TheNdreeves I would apply topcoat for pinholes and hairline cracks but for anything bigger than this I wouldn't advise
@@Mezquita100 I have lots of pin holes and fiber glass that wasn't properly soaked with resin. Would you suggest putting additional layer of resin and glass fiber matt?
Why would a fibre glass roof need recoating. if it was a 3 layer torch on roof, it would last at least 30 years.
he told you at the start....the topcoat had worn away
So it was over 30 years old than ?@@stevehallam6495
@@MrFlatroofer how do I know? Probably not but he said his basecoat was fine so he gave it a new topcoat so back to as new.
