Cost to replace a roof

Has anyone done a roof recently in CPT? Cost per m2 for a tile roof including trusses etc?
 
I recently had relatively standard roof trusses made up, and it cost me R21k for the trusses, battons and fixings for a 100sqm roof.

Roof tiles were an additional R12500 (give or take).

Labour was included in a different quote since I am doing a relatively extensive renovation.

Is the labour cost extensive? Did you have to order the trusses and tiles yourself?

By the way, who designs the roof? The architect of the builder? Im thinking of extending an existing roof, so who would do the design to merge the two sections?
 
Well I was building a double garage and workshop, so best guestimate was R10k labour to erect the new roof structure (there was no old roof to pull down).

The architect should give a rough indication of the roof design, but the guys who build the trusses will do the final design.

I did order everything myself, purely so I could keep track of the costs involved. Theoretically, if you're extending an existing roof, the trusses should be the same design, and it should be easy to tie the two together.

Thanks dude, more advice needed though.

Effectively I want to extend a garage forward right, see pic below:

The garage looks almost exactly like that. So I want to make it longer, and obviously break down the existing front wall and then just continue the roof and have a single double garage with no slit in between. Does that make sense? Your thoughts?
 
Should be entirely doable..

The roof span won't require any special engineering since its a double garage width (7m give or take).... You will have to be careful when you rebuild the front wall in its new location, that you get the right type of lintel to span the distance, but it shouldn't be too difficult to find.

I would guess that your building cost will probably be large than the cost of extending the roof tbh.. depending on how much long you want to make the garage structure.

Looking at extending it about 8metres forward (8metres x 7metres = 56m2). Would I be able to break down that wall completely and extend? I know it's difficult to say without actually being there. Cause then the roof would look uniform on the inside.

Oh I forgot to mention, I want the new extended roof to look like this instead:

So the garage will look like this without the slit:

What do you think this will cost for the walls and roof structure? Have any idea? Do contractors charge a lot to break down walls?

Im assuming the walls would costs about R2000 pm x 8m = R16000 x 2.
 
So you want to change the entire roof structure... eish, then it gets trickier because you have to take the entire roof off unfortunately..

From a cost point of view, I would not suggest going down this road tbh, its just pouring money into something that will never get you an increase in equity to equal the cost.

You would be able to break the existing wall down completely, its a Gable wall, so theoretically its pretty much only holding up itself, and a maybe 2 columns of tiles (which would eventually be supported by the new roof trusses anyway.

Unfortunately I have no idea of the cost of building and breaking walls in CPT....
 
I have the exact same requirement. I wish constructions with flat roofs would be abolished :)

No, not changing the existing structure at all. Let me try and illustrate (my drawing skills are horrible):

Im keeping the existing structure as is (pic on the left, and would like to extend. But instead of ending the new section as an open Gable wall, I would like it to end like the pic on the right. Understand? Instead of having a Gable wall, I want the new roof to slope downwards, but only on the one end of the new section. The existing section would stay as is.

What would be the cheapest/easiest option of extending in your opinion? So the existing Gable wall serves no purposes other than well, being a wall? The trusses are then supported by the side walls?
 
Ahhh ok,

Then it should be very simple really, but you will need to make sure that you "new" section of end wall is up to holding that extra weight, because the "hip" section of the roof will be supported on the wall.

With a gable wall, the roof is supported on the side walls pretty much, the gable is just to fill in the space.

Personally I'm not a fan of Hip roof structures, they limit "storage" space.. and just general access in the roof, but to each his own.

Ah, I understand. Two reasons I was thinking of "Hip" is, wouldn't it be cheaper to have the roof pitched instead of having a wall built upwards? Also I do like the look of "Hip".

In terms of space, I very much doubt I will use the roof space. Maybe in the longer term I would look to having an attic, but not anytime soon.
 
Oh yes, would I be able to use a draughtsman to draw up these plans or would I need an Architect?

Does your rates increase in you increase your garage or living space?
 
Draughtsman will be fine..

And yes, your rates will eventually increase, because your property value will increase with the additions.

Thanks all the advice.

Any builders on this forum who would be able to give me a rough idea of what this would cost?
 
Honestly do yourself a favour and go to Chamberlains and get a quote on your roof. Their Watloo Branch in Silverton will do it for free (for the material).

Buy the material and let the contractors make their price.

Very good advice this....

(Not that I have experience with Chamberlains specifically)

Sounds like this place is in JHB? Know of a CPT counterpart?
 
Hi everyone. I have just purchased a double storey thatch house in durban. The house is 680 mtr2 in total. I would like to remove the thatch and gumpoles and replace it with new trusses and tiles. Some of the walls will need to be built up higher to change the pitch as currently some gumpoles cut low into the bedroom walls and take away room space. Does anyone know roughly how much this project will cost? Thanks.
