Flat or slightly sloping roof question
 

Looking at replacing a small flat roof on an extension (thread a couple of
months ago).

Expected cost around £1k.

I was looking at the powder coated steel roof of our shed the other day
and thinking that it was looking pretty good 3 years or more on.

I know that this is not a traditional finish for a flat roof on a domestic
property, but is there any other reason not to?

Cheers

If it were me, I'd consider zinc or aluminium.

Noise? ether when it rains, or possible annoying clicky noises when it
expands/contracts ...

Is that not going to generate a lot of noise when it rains?

It works well. But eventually it'll be a rusting eyesore.

Many years ago when I lived in Australia :-( some houses had "tin" roofs.
Apparently when it rained the noise was awful.

I lived in a tin roofed converted garden shed in S Africa. When it
hailed, which it did, often, it was deafening.

Mind you it wasn't insulated either.

I assume that insulation, joists & ceiling would much reduce the noise.

I'd personally have galvanised instead of powder coated.

Even sillier than you usually manage.

I just dont believe that it hails anywhere often.

They dont actually with hail. But it isnt hard to have rockwool or similar
insulation immediately under the metal decking with chicken wire under
that which holds the rockwool up against the underside of the decking
which makes a hell of a difference with heavy rain.

We have a powder coated steel roof on our house extension (specialist
roofing from Tata Steel) but this is designed to look like a zinc roof. It
is a number of sheets with crimped joints. Looks pretty good.

It isn't particularly noisy in heavy rain because it is laid on wooden
sheets (can't now remember if they were OSB or chip board) designed for
roofing.

Under that is a significant amount of Celotex (or similar) to modern
building regs.

However here I am looking at the corrugated (square section) roofing more
commonly used in agricultural buildings.

It won't look pretty, but it should be durable. Possibly as durable as
torch on felt.

It has just occurred to me that if it does get worn out (or at least
rusty) then all you have to do is unscrew the bolts and bolt new metal
sheeting in place.

Just idly toying with the idea at the moment, but it could be an
interesting option.

Yes - that's unlikely to be much different to a felt roof as the mass of
the board stops it resonating as well as attenuating the noise. As will
the plasterboard ceiling.

Steel sheets with no boarding are likely a different matter.

There is a similar alternative made out of zinc. Expensive.

The tin has several inches of insulation under it. The major problem is preserving the weather seal at joints. Tin flexes in violent winds and expands and contracts a lot more than stone or clay. Large sheets being both a blessing and a downfall. I imagine going around the finished product with a soldering iron might be the only way to cure that.

Not necessarily, we have a wet winter at the moment.

major problem is preserving the weather seal at joints.

Not with metal decking which has no joints at all where
the water is, it is one continuous length with the joints
well up from the deck itself where there is no water.

Tin flexes in violent winds and expands
and contracts a lot more than stone or clay.

Yes.

Large sheets being both a blessing and a downfall.

Not when they are long and thin with the joint well up from
the deck. Which is why metal decking is done that way.

I imagine going around the finished product with
a soldering iron might be the only way to cure that.

You're wrong. The way to fix the problem is the way
metal decking does it, very long sheets that have no
joints at all where the water is with the joints between
the individual sheets of decking well up out of the water.
Works very well indeed and very easy to lift up a sheet
to get at the wiring etc and put it back again too.

Wouldn't the solder tend to come away from the steel when flexing occurred on hot sunny days?

I recently had a shed roof [Corrougated Steel] replaced, one of the
items charged for that was not included with the original was a tub of
grease. This it turns out was to lubricate the overlapping flashing
that covers the wall/ roof at the edges that don't drain.

Not sure how long it lasts though and I dont see any grease noipples
anywhere for the service :-(

Zinc reacts with sunlight so they used to paint the roof after putting it on. It comes ready treated these days. Why would they use a metal flashing that could rust?

Yes it is, I think the flat stuff is aluminum. It is bent over the
wall and continues down it for about 400mm. Around a metre lies on the
corrugate. The corrugate was cemented to the wall around half a block
from the top. I suspect that the new corrugate is no longer fixed to
the wall as that was the point where it rusted. I will ask the person
that did the repair as it is around two years since the work was done
and in the warm weather there is the occasional clang from the roof.

Zinc reacts with sunlight so they used to paint the roof after putting it on. It comes ready treated these days. Why would they use a metal flashing that could rust?

The flashing doesn't rust. Sorry I didn't make things clear.

I think the corrugate was treated, most of it was in perfect
condition. Only the bits close to the cement bridging the corrugate
and wall were rusted.

Not when the roof is designed properly so the metal can move.

If the metal moves, the solder is put under strain.

Not if the design allows the metal to move without any strain.

That's how metal decking works, there are clips under the decking
and no screws thru the decking at all so there is no strain on the
metal at all as it heats up and cools down with the weather. Don't
get any clicking from the decking either.
