Hi All,

I asked a while back about considerations when raising the pitch on a
garage / workshop roof (to make more of a 'loft' / storage space) and
I'm now, after seeing some in use, considering that pre coloured galv
steel roofing you often see in the bigger profiles cladding the walls
and roofs of the sheds we all know and love. ;-)

I'm told it would be much noisier than the existing corrugated cement
fibre (and I would have to replace that anyway as it would be too
short with a higher pitch) but I see you can get self insulated
panels but not sure if they meet the requirements of 'non combustible'
(I'm thinking of the insulation rather than the panels here).

I've even seen (but now can't find) a simulated slate (I've found the
tile one) that would be in keeping with our and many of the houses
round here.

The pro's for me could be that it might be lighter than cement fibre
(easier for me to do), possibly more secure (you couldn't just break
it open) and could be pre-insulated?

So, has anyone here used such stuff themselves and can point out any
pitfalls etc please?

All the best ..

I've lived in tin tops in africa. BOY they get hot.

Definitely put insulation under.

Don't worry about noise. Just make sure there is something inside in the
way of e.g. plasterboard - that will cut the echoes down.

try

I used their 80mm AS35 foam sandwich for a large, pitched roof workshop
without any real problems.

Points to consider are....

the sheets arrive cut to length: one end square and the other
having a 50mm rain drip (insulation and under sheet cut back). When you
fix this as a lean-too or ridge there is a triangle of uninsulated
space which needs filling with fire rated expanding foam.

flashing is made to your specification but sits on top of the
roofing ribs. Metre wide foam gap fillers are available but need to be
trapped by the flashing fixing screws.

Fixing screws are available for metal or wooden purlins.

rolls of mastic tape are required to prevent heavy rain bouncing under
the lap joins. This is applied to the underside of the lap but requires
care when lifting the sheet into position. Pair of hands needed at top
and bottom. Lap stitching screws are essential.

The biggest problem I encountered was how to attach the guttering and
how to seal off the exposed foam. Steadmans did not offer any solutions.
In the end I got some 100mm x 75mm pine cut diagonally (done by my
timber supplier with a band saw) which suited my roof pitch. Fixing was
by some home made *Z* shaped galvanised steel strips and the wood dosed
with preservative.

Things you may not realise about ribbed roofing..... not all buildings
are built square, my barn is 1m longer on one side than the other. This
is not a problem where the gutter is longer than the ridge however, on
the other side, the ribs conduct rain water over the end of the
building. Luckily I had some left over extruded aluminium gutter from a
greenhouse which was fitted behind the flashing.

Brilliant. That was one of the profiles I considered (I spotted it on
another site). Can you remember roughly how much it cost please Tim?

Gotcha. I wondered how you / they dealt with that ..

When you
fix this as a lean-too or ridge there is a triangle of uninsulated
space which needs filling with fire rated expanding foam.

Understood.

flashing is made to your specification but sits on top of the
roofing ribs.

And considering the up to down ratio on that profile there would be
some fairly considerable sized gaps! It was that area that started my
questions previously. The existing low pitched roof came with a pre
moulded cement fibre ridge and that excludes all but the smallest of
gappage at the ridge. I wasn't sure if this was a common solution that
was available in a variety of angles but as yet I'm still not sure.

Metre wide foam gap fillers are available but need to be
trapped by the flashing fixing screws.

Understood.

Fixing screws are available for metal or wooden purlins.

Ok ..

rolls of mastic tape are required to prevent heavy rain bouncing under
the lap joins. This is applied to the underside of the lap but requires
care when lifting the sheet into position. Pair of hands needed at top
and bottom. Lap stitching screws are essential.

Understood and ok again ..

The biggest problem I encountered was how to attach the guttering and
how to seal off the exposed foam. Steadmans did not offer any solutions.

Isn't that strange. They make a product then sort of run out of ideas
on how to use it?

In the end I got some 100mm x 75mm pine cut diagonally (done by my
timber supplier with a band saw) which suited my roof pitch. Fixing was
by some home made *Z* shaped galvanised steel strips and the wood dosed

Ok ..

Yeah, I guess that's bound to happen quite often, especially with
older buildings.

This
is not a problem where the gutter is longer than the ridge however, on
the other side, the ribs conduct rain water over the end of the
building. Luckily I had some left over extruded aluminium gutter from a
greenhouse which was fitted behind the flashing.

Handy. ;-)

I was thinking of building a little forward overhang into the
replacement roof to offer a bit of cover over the doors so would also
have to do something gutterwize.

I guess it might come down to cost in the end, based on the cement
fibre at the lowest and working up from there.

All the best and thanks for your time and info Tim

November 2006 AS35 80mm composite sheeting cost £23.78/m

I also bought some AS35 40mm seconds at £7.73/m. Seconds are slightly
damaged: dented/overlong etc. They are exempt from LPC approval so may
not be a good idea for a domestic installation. I used a metal cutting
circular saw to cut them but there may be other ways.

For a ridge, you will need internal and external folded section at
around £5.00/m. Ridge fillers at £0.75ea. Also 90 deg. barge at a
similar price. Fixings are not exorbitant.

Delivery might be an issue as these usually arrive on an artic fitted
with a Moffet Mountie fork truck. Delivery to Herts. was £150.

I guess you have 3" cement fibre in self colour. I found delivery times
on painted *big 6* sheets had reached 3 months, recently.

Ouch .. :-(

That is slightly better (considering it is already insulated etc) but
still not cheap if you are d-i-y'ing (ie, not having to pay labour).

Seconds are slightly
damaged: dented/overlong etc.

I guess if that was say a sheet of polycarb or cement fibre you could
easily cut off the excess or lose a damaged corner somewhere where it
didn't matter. I seems this AS35 is quite a 'engineering' solution in
how the joints are made / sealed etc.

They are exempt from LPC approval so may
not be a good idea for a domestic installation.

Even for something like a fully detached workshop Tim?

That's another couple of hundred quid?

So would be the same for me (Herts) as it's probably per load rather

Oh, ok, well in the real world I have a lot of work to do before I get

is this something that would need re-doing in time?

Umm.. My insurers (NFU Mutual) were quick to ask if the foam insulation
met the regulations. ISTR this was changed a few years back so my
concern was that *seconds* might be the earlier version sold without LPC
approval. Mine were used for stables so no human occupation.

I have some offcuts if you are that close and wanted to play.

nips out with tape measure Yep ;-) While we are on the subject,
would you know what other colours are available please?

Slate blue (preferred by our planners as we have slate roofing
elsewhere), Van Dyke brown, Juniper green, Merlin Grey. Other colours to
special order.

I think Brookers at Hitchin might supply locally or try your local
builders merchant.

I found delivery times
on painted *big 6* sheets had reached 3 months, recently.

Oh, ok, well in the real world I have a lot of work to do before I get

Not really. The surface will degrade slowly and may support lichen in
damp climates. The paint will fade over the next ten years.

I suppose there are more D.I.Y. solutions such as fitting an undersheet
below the purlins filling the void with rockwool and then fitting
plastisol coated roof sheets over the top. Wall sheets are cheaper as
they are normally 0.5mm thick compared to 0.7mm for the roofing.

It can be...when you're on the phone.
It also tends to amplify the intensity of the rain...it sounds like
Armageddon has arrived early, and when you open the shed door to take
a peek at the spectacle you find it's just a light shower.
As for hail, well, that just gets silly.

I quite like the sound of rain, especially when I'm trying to get to

Myford. ;-)

LOL. We have a poly carbonate lean_to roof that has a similar effect
and is normally our 'audible rain indicator'. ;-)

As for hail, well, that just gets silly.

I bet!

So, if I can get some sort of resolution to the ridge question, maybe
corrugated cement fibre would be a cheap / quiet / cool (as in temp
g) easy_to_source solution and potentially less likely to attract
any attention (as it's what's on there already).

I will just have to design in (and will have more space for with the
increased pitch) some form of roof lining (the walls are lined with
ply and insulating material already).

All the best

Lol. Seriously though, its nothing like that bad. In fact it isnt bad
at all. The sound gives early warning of rain, which is handy to
enable the quick dash to the house before it starts raining properly.

sure - but nothing like corrugated iron, which is a real condensation
magnet. If your asbestos condenses a bit you could open a
waterworks with iron.

A few mm of insulator vs less than 1mm of good heat conductor.
You still get hot roofs in the sun, but less so and its not all

Well... it sure was popular. The reason it isnt today is its become
associated with the dreaded asbestos word. Bear in mind how long
those roofs have stayed up for, maintenance free.

steel roofing you often see in the bigger profiles cladding the walls

I'm told it would be much noisier than the existing corrugated cement

corrie is relatively noisy in the rain, but I dont see it being an
issue.

Have you considered using Decra tiles? -- very easy to put in position
single-handed. Excellent end result.

Not till now. ;-)

It looks like they are designed to be alternatives to traditional
tiles / slates on traditional roofs? ie, I'm not sure they would suit
the big open frame that is my sort without some sort of sub roof
sheet?

Certainly need something to fix them down to, but the end result is a
great deal better than most of the alternatives, imho.

I would have to use some sort of 'non combustible battens as I believe
that is part of the 'permitted development construction.

I suppose I could screw to a steel purlin as easily (if not quite as
fast) as nailing to a wooden one?

Hi All,

I'm told it would be much noisier than the existing corrugated cement
fibre (and I would have to replace that anyway as it would be too
short with a higher pitch) but I see you can get self insulated
panels but not sure if they meet the requirements of 'non combustible'
(I'm thinking of the insulation rather than the panels here).

I've even seen (but now can't find) a simulated slate (I've found the
tile one) that would be in keeping with our and many of the houses
round here.

The pro's for me could be that it might be lighter than cement fibre
(easier for me to do), possibly more secure (you couldn't just break
it open) and could be pre-insulated?

So, has anyone here used such stuff themselves and can point out any
pitfalls etc please?

That looks interesting Rob.

Funny though, after folk have got me thinking about the heat aspect, a
light cement fibre grey seems it might be a good colour to reflect the
suns rays?

Depending on the price and finding a suitable corrugation match I
wonder if I could use Onduline in it's underlay role (it mentions
using it under tiles and slates but if it can 'oversheet' existing
corrugated roofs I guess it can 'underlay' as well? g).

All the best ..

I used some Onduline back at the last place.

Advantages - it's relatively cheap, doesn't rust or rot, light to
lift, easy to cut to size - but use an old saw - quite messy!

Disadvantages - needs cross-support at the recommended intervals
as otherwise it will sag under the effects of sunlight / heat.

Used it to roof one of the woodsheds (6ft x 20ft) and a chicken shed
(only 6' x 4').

Good stuff, IMHO

Only that it needs a lot of supporting as it lacks the rigidity of
cement fibre.

On the condensation issue.... cement fibre is good because the surface
is porous and can retain some moisture to evaporate off when things warm
up. Steel can be coated with *felt* to a similar effect.
