Thank you for watching our GRP / Fibreglass Roofing Installation Video. If you would like to purchase any of the materials we have used, please visit www.fibreglass...
GRP is so easy .... One days course and a bacon sandwich. And your ready to go! Which is a total mockery of the four year apprenticeship and three years I spent at college 🤨🤨
Great presentation, I've got a question, could you flash fibre glass on to a metal standing seam roof around a roof light to make it water tight and would it it last, pitch is bout 10 degrees on it, the metal roof will be fixed down on plywood roof, thank you,
Really informative. Thanks for posting. Is it ok to install a new roof deck from 12mm OSB over an existing fibreglass roof (that was originally installed poorly) and install the new fibreglass roof on this new deck?
We stock a flexible resin which adapts to roof contractions and expansions. We've been selling Fibreglass Roofing products for a long time with few complaints. A lot of the issues with fibreglass roofing come down to poor application.
Depends if you do warm deck or cool deck construction. If doing cool deck with insulation between joists you should leave 50mm ventilation gap above the insulation and allow for cross ventilation from the front to the back of the roof.
If I want to remove let's say a extractor fan from the roof which has been fibreglassed. Is it possible to reapply fiberglass to the area after filling in the hole?
Yes, grind out the fan unit and remove, fit any timber joists underneath, fill in the hole with decking making sure its level with the rest of the roof decking san down the existing roof around the fan opening back to about150mm, and then simply laminate and topcoat to finish. Simples
Hi Harry, it sounds like your Topcoat did not adhere properly. This can be for a number of reasons for example the surface was contaminated. The good news if there are no leaks etc. this layer can be sanded back and a new layer of topcoat applied.
Hello, we wouldn't recommend painting over the topcoat. A new layer of topcoat may be applied but original layer would have to be sanded back first and cleaned down with acetone.
We do get a lot of enquiries from the U.S about fibreglass roofs. Not too sure why, but there are some suppliers over there. This type of roofing system is definitely not as common.
They do proper jobs in USA & Canada. Seriously, how durable are GRP against more extreme climate of North America? Snow, deep freeze, monsoon rain, desert heat, etc.
This is the colour of roofing topcoat that we stock, some people do go for a lighter colour but we find dark grey is normally our customers preference.
Oh my god!!! You have to be the bionic man and read 3 million words a second to watch this!!!! Lost count of how many tines I have tried to pause and rewind...trouble is when you pause to read TH-cam have covered the words with a myriad of symbols....it's absolutely Impossible to watch

... when your flat roof is at knee-height - always makes it look easy and a great finish is easily achieved! try this outside and 12 feet up...
Or even 40 feet up and drizzling.
Using a 4" roller seems like an interesting nightmare to purposefully impose upon yourself lol

Listen that's nothing half my trade went with no lead work and the real carpenters the real skills r going
It was truly useful thank you FGD (: !

Tell them people to do some push-ups. That stapler and caulkgun was giving them hell
I have a few patches of rubber paint, will top coat work over it?

Yes, that's called lasagna style and is favored by Italian tradesmen.
@@felixhelix6171 shut the fuck up
Calm down bender
I wouldnt. Rip it off n start again.

GRP : a material so singularly foul to handle and apply, you must ask: does a problem exist that is worse than this solution?
Only if you don’t do the correct prep
Fibreglass splits over time in different weather conditions and perish alot.
We stock a flexible resin which adapts to roof contractions and expansions. We've been selling Fibreglass Roofing products for a long time with few complaints. A lot of the issues with fibreglass roofing come down to poor application.
complete bullshit,fiberglass is inert,and no expansion or contraction qill crack it short of an earthquake,another no nothing internet expert.
@@mariomartin1981 he might be referring to the crazing you sometimes see.
Are acetone and white spirit interchangable for cleaning the surface in preparation?
Great video. Awful music and no need for it.
Thanks for the feedback Martin, we'll take note for next time.
Do you still need a breathable membrane under a grp roof for a garden room with 2" of ventilation between insulation and roof?.
Depends if you do warm deck or cool deck construction. If doing cool deck with insulation between joists you should leave 50mm ventilation gap above the insulation and allow for cross ventilation from the front to the back of the roof.
Warm deck or cold would’t need a breathable membrane with a GRP top, vapour barrier yes, but I don’t see how a breathable membrane is appropriate.
Is there any reason why a sedum roof couldn't be laid on top of this system?
wtf is that windows notification sound in the music lol
I have drips from resin can this be fixed?
Can the fibre glass roof be applied directly to a PIR insulation board, or wood fibre insulation composite board - such as STEICOprotect dry?
I wouldn't apply direct to pir board. Clad with OSB or ply.
How many builders carry a set of scales to site???
All the sniff heads

Sarb S yes you can

Wish my two roofs looked like this. Top coat is peeling all over. Any ideas as to what's gone wrong?
Hi Harry, it sounds like your Topcoat did not adhere properly. This can be for a number of reasons for example the surface was contaminated. The good news if there are no leaks etc. this layer can be sanded back and a new layer of topcoat applied.
If it hasnt been sanded the gel coat will just peel off
Sounds like a few things either topcoat has been applied to a dirty no prepared cold surface 👍
I had this problem, dried roof sanded down and re applied a fresh tin of topcoat and added more catalysts, poured shit loads on.....its solid now 😂😂
if you does it properly does not peeling off for sure doing this job for 10 years
can box gutters be fiberglassed in as well?
Yes
Can you paint over the topcoat? If so, what kind of paint should I use?
Hello, we wouldn't recommend painting over the topcoat. A new layer of topcoat may be applied but original layer would have to be sanded back first and cleaned down with acetone.
Any idea why this is almost never done in the U.S. and Canada
We do get a lot of enquiries from the U.S about fibreglass roofs. Not too sure why, but there are some suppliers over there. This type of roofing system is definitely not as common.
I would love to be able to purchase the hard edge parts to make the whole thing easier. Any chance you want to start selling over here?

25mm gap between boards? 3mm surely?
Between the boards and wall. Not between the boards themselves. No gap is needed with T&G.
Video implied 25mm between boards and between boards and wall. I'll be doing 3-5mm between boards and 25mm between wall.
Talented guys these... they'd just come from lab, designing the covid vaccine!
Didn't even have time to get changed!!
Life expectancy?
Hello, once properly applied a fibreglass roof will easily last in excess of 20 years.
sir aap Khan se ho or kya mkaan ki roof pr bhi lgwa skti hai
No, they dont do it in curry flavour.
@@Daisy-ef6bq😂😂😂😂😂😂😂😂
Why this top coat Black instead of any light colur
This is the colour of roofing topcoat that we stock, some people do go for a lighter colour but we find dark grey is normally our customers preference.
We have lots of coloured topcoats too but we stock 2 specifically for roofing.
Black top coats matter.

The myriad of symbols disappear if you tap or click on the screen again, obviously anywhere but near the pause button 👍
All well and good when you doing it in sterile conditions indoors but nobody puts a roof on inside a building so pretty pointless really
Hahahahahaha😂😂😂😂😂😂
