Problem with this is that you need to take the air somewhere.

Also bathrooms usually aren’t wired up for electricity (except maybe lights). Though maybe that’s an option? Switch the fan on while the lights are on?

I have duct routing the air towards the roof/edge of the house.

Yes, you could also add one of those smart Wi-Fi switches to the fan if you really need to.

If your roof space is big enough and vented properly, as it's supposed to be, it's fine venting into the roof space.. either way, most extractors include some length of ducting anyway..

As for electricity, it shouldn't take a competent electrician more than an hour two to run a supply for the fan and install a two gang light switch to have independent control over the bathroom and fan..

Generally you connect the extractor to the lights. But there is regulations regarding the switch if used for a fan as well....


You can use 110mm plumbing drain pipe and bends to lead the air somewhere.
Best is straight through the wall. Mine is in the ceiling with a 110mm bend leading it through the wall...
 
Need urgent help. What would be decent quote for this ?
  • Retaining wall dimensions: 18.1 linear meters.
  • The retaining wall will be double brick 3 coarse wall which will be plastered.
  • To supply the concrete and lay the foundations for the retaining wall.
  • To supply and build the retaining wall.
  • To plaster the retaining wall.
  • Labour.
  • Building materials.
  • Sundries.
 
Break down and tell us how high the wall must be.
We'd need the height of the soil being retained and the height of the wall, if higher.
Also do you need an agricultural drain and/or drainage holes.

Thanks. Wall is 50cm high - just around garden beds. Sitting on 15cm soil. There will be 2 drainage holes.
 
18.1lm of foundation @ R280/L = R5058
18.1 x 500mm of double wall R5610
Plastering both sides = R2780.
Waterproof leading side R680
Total R14 126

Notes:
You don't need a triple wall.
Triple Retaining wall will double the price of items one and two.
The leading sidewill need Coprox in the mix to waterproof.
SABS plastic should be laid against wall before backfilling.

Note: Wall is not a load bearing wall and should never be used as one.

Price excludes backfill, plastic and VAT...

Noticed some mould starting to build up in the bathroom on the ceiling and cornices. Is it necessary to remove the mould or can I just paint over it with an anti-mould product?

I also have a mold issue EVERY winter in our bedroom - roof turns black...real pain in the ass.

I run a dehumidifier once a week for 8 hours - only barely helps, the humidty stays down for a few days - then back up again.

The cleaning products you get, like MoldBuster - work - but - its never permanent.

Do you have insulation in the roof, like think pink or isotherm etc..?

You'll have to run the dehumidifier way more than once a week.

Mine runs all through the night and then during the day too if it's wet outside.
 
I know I've asked this before, so here we go again, We've had multiple roofing companies out - spent north of R100k - none do a good job.

Where I've marked in yellow - there is no overlap between the wall and those flat cover plates. You can actually see it clearer on the parapet wall perpendicular to the one I've marked in yellow. Its basically just butt joined. (even with the torch on)

The last company took the torch on approach for the parapet walls - and I again questioned no ovelap - and again was told its right like this.

Roof.png
(side story: the various shades of red are from my now annual trip up the roof in April to waterproof what could be a problem in the rainy season).

Now my issue - 100% of my walls visibile below which have no ceiling boards (patios/walkways/etc) have water streaks,

Then in various other parts, the water makes it way past the ceiling boards and runs down the walls...

Does anyone know why they say there musnt be an overlap?

I have a section inside that looks like its raining every morning - just from the moisture buildup on the roof because of the cold - I peaked in the ceiling this afternoon and the entire section with the yellow marking (about 8m) is sopping wet (and we haven't had rain this week).

At this point, I'm planning on buying waterproofing membraine and painting it on everywhere where there isn't overlap.

So this moisture occurs even when it's not raining?
 
WAslayer said:

Nope - and not possible to get it in. The cavity between the ceiling and roof is between 30-60cm - and some parts are not reachable. Looked into getting the spray in stuff - but apparently because we have downlights everywhere - its an issue.

On the actual roof itself, i.e. outside. I've been up a few times recently for other reasons, and its always wet in the morning.

Its not a humidty problem like our bedroom - its our lounge which has a fireplace in frequent use, the humidity in the room stays between 40-60%.

Did you get Thomas to come by? https://morgnerroofing.co.za/contact/

When they redid my roof there is a foil vapour barrier that goes underneath the sheeting to prevent that moisture accumulation. It would obviously be costly and disruptive to get that done as the roofing would need to come off.

This is what it looks like from the inside:

I'm still confused, is this a roof leak issue?
Does the water run down the walls only when it's raining?
Or is this a dew/frost/humidity issue?

No - but - I'm kind of over trying different companies and spending unnecessary money on it - I've had multiple come out and quote, and used about half of them. These guys are making more than I do in a month for what takes them a day or three with two/three guys.

The least amount of leaks I've had is when I started maintaining it myself, hence wondering why there is no overlap of sorts.

The membrane you mention is actually there - BUT - has started coming off where the roof sheeting meets the wall because its filling with beach sand blown in from the wind. (again - no overlap).
