We are thinking about changing from flat roof to Apex. Do we need permission, have to check with neighbours, plans etc. Please advise. Regards, Haidi. Haidi, you will need to submit plans to your local authority, and the roof must be built in accordance with SANS Part L Roofs, which is covered in some detail on this page. Hi Prak, Apologies for taking a few days to reply, but I must admit I was a little taken aback being asked a question by the CEO of a respected firm of architects.
Having said that let me try and answer as best as I can. As you know the intention of the regulations is to ensure that all buildings are to be waterproofed according to their designated use.
Two other comments: 1. They set out, in the simplest and shortest way possible, requirements to ensure that buildings will be designed and built in such a way that persons can live and work in a healthy and safe environment. Apart from other textbooks, a qualified concrete technologist would be able to advise whether additional waterproofing would be needed.
More important is the concrete mix design and any reinforcing including its placement required. Hi, I bought my house Kempton Park about 4 years ago. I have had some alterations done and addad a double garage. Now I want to knock out a weight carrying wall inside my house. I was told a laminated beam across could carry the roof load.
How do I go about this job. I had an engineer come out 2 years ago, still waiting on a quote. Tiled roof You need professionals on the ground who can visit your house and make sure it is all going to be done properly. Hi Penny, thank you for the advise regarding expansion joints for flat roofs. Can you please provide me with the correct slope on a corrugated roof of a carport with a width of seven meter.
The carport is open on the sides. Hi Kerneels, The regulations for corrugated pitch roofs say: 4. Table 1: Corrugated including box rib profile galvanized iron, polycarbonate and fibre glass 11 to 22 degrees. You can read more on this page. What type of roof anchors is required when doing maintenance on asbestos roofs.
Is crawl boards necessay. First of all Irvin, If the roof is indeed asbestos, then you need to take special precautions when working with it. I will put up a new post on asbestos in the next few days and send you a link.
Hopefully it is fibrecement. The actual size will depend on the structure of the roof — timber members in particular. It is advisable to use a crawl board. Are there any building regulations related to irrecting objects on roof tops e. The building regulations do not cover erection of solar panels and solar geysers on roofs. The local authority may have by-laws that affect them. You can ask who the manufacturer was and find out if the softwood timber SAP that was specified meets the specifications.
We mainly deal with the SANS on this site but help where we can. I would like to know if I need building plans drawn up and approved for a lapa with a concrete tiled roof less than 20 square metres in size? Nadine, if it has a tiled roof, you need a properly built roof structure and so it is quite likely that your local authority will need plans.
You need to ask them — ultimately they have the last word. Hi James, Yes it is possible to use maxi bricks for your project. It does not make any difference if you are building on a farm if you do not submit your plans for approval before you build then you will be breaking the law.
Is this true? Timber poles are less likely to rot if buried in concrete rather than in the ground, but you should always use some sort of sealant on the ends first — e. BTW cement is a powder that is used with sand, stone and water to make concrete; it is never used on its own.
The complex that i stay in was built in with a roof angle of 18 degrees. But the regulations recommend checking with the manufacturer. Bethuel let me know the answer and what score you get for your assignment. Not sure what you are doing here. Hi I would like to know whether thatched roofs enquire gutters for the release of rain water or how does it release the rain water?
Good day Could you kindly assist with what height a flat concrete roof is built to, above level ground. I am doing a college project on solar panel installation in a rural environment and urgently require this dimension for my water pressure drop calcs. Many thanks for any assistance.
Kind regards Mark. Mark, to be able to give you this information and ensure it is accurate we would have to do some research. Contact people who do solar panel installations. Mkholisi, The water flows off the thatch, but there should be a skirt of concrete or paving around the foundations to help channel the water away from the house.
This is why thatch roofs require a steeper pitch. The thickness of the thatch is also specified in the building regulations. You can read more in this article about waterproofing roofs.
I have had a duratile roof fitted by Roofix They are extremely unprofessional and untidy. There are exposed nails all over, and when I asked them about it I was told that is normal with these tiles. Here is a link to the way that they should be laid. Your best bet is probably to get a representative from Duratile to visit your site and give an opinion.
It looks as if they have offices in Durban and Brakpan If you live elsewhere they may be able to send a reputable installer to check for you.
It is also best to use reputable companies to avoid this type of problem. Hi, I am designing a low cost building. They asked for a wooden roof no roof tiles, no steel sheeting what does the building regulations say with regards to this? First of all Monique, with all due respect, you should not be designing anything if you are not au fait with the National Building Regulations.
Legally you need to be a competent person to be allowed to draw and submit plans! Even reading what I have posted on this page — which quotes the National Building Regulations and Standards Act — you should be able to tell that a roof has to be constructed in such a way that it will not be adversely affected by weather conditions — including the penetration of rain water.
You have to have some type of SABS-approved covering. Penny I am building a house for somebody, but insists on a roof with a ceiling right at the top. So, no normal trusses.
Laminated pine beams, will do the trick,I think. However I need some formulas to calculate the stresses,the right spacings and thicknesses of the beams. Unfortunately the total length is x That involves the open plan kitchen and lounge. Martyn I am not qualified to give you formulae. Apart from which the rational design of the roof needs to be done by a person who is competent and qualified to do so, and it needs to be approved by the local authority.
If you are not competent to do this, you will need to employ someone who is. This is a mandatory requirement in terms of the National Building Regs. Hi to all I have a problem, I had a storm that damaged my tiled roof, The house has been built over 20 years and has always brushed off the forces of the winds. Meaning that the purlins are to far spaced apart to far. I know the law now states mm for tiles, but what was the law 20 years ago.
I am building my own house out of my pocket. The roof is flat with laminated beams, any suppliers who might quote me for a good product at reasonable prices.
My spacings of Rafters are 1. We had a hailstorm and the roof leaked a lot. The insurance company sent someone to check and according to them the roof is not built according to standard and therefore they are not paying any damages it has a pitch of less than 5 deg. They also said that in future they will not pay until the roof is fixed,.
As a competent person Brynn I would have thought your knowledge of the regulations would be much more thorough than mine. I assume that your engineer would need to draw a custom plan for the roof that accommodates the measurements safely. Thomas, several thoughts. Firstly, the National Building Regulations and Building Standards Act was only promulgated 36 years ago and there is no law that states old houses have to be redesigned or rebuilt to meet the current regulations.
Secondly, you need to check your insurance policy carefully to see whether they state anything like for e. Thirdly check the fall of the roof according to the current regulations, viz: 4. Where two directional falls intersect, the minimum finished fall of shall be maintained along the mitre. See figure 2. Jacobus, the purlins required for sheeting should be considerably more substantial than the battens used for tiles. Working backwards, with a 1,2 m spacing, you should be using either 50 x mm, 50 x mm, or 76 x mm purlins.
I need some advice please. The length of the patio is 3. What is the minimum size of the supporting beam? The beam will be supported by brick pillars on each end and the roof pitch 11 degrees. They have included many more specifications in the new regs. Pieter you need approved plans drawn by a competent person to be able to do this legally. That person will advise regarding timber and dimensions.
HI can anyone help me or give advice? I bought a house in an estate, which had an existing carport only paved and covered by a louver roof now there seems to be problems brewing about these roofs and apparently they want us to remove them.
Is this legal? Do we need any plans for these roofs? Message: Hi, I have bought a house 14 months ago. There is no isolation in the roof. It has 2 sections of a Gable roof type with a flat roof between. Tile roof type. Is this within the minumim requirements of the building code. Willem there is fairly detailed information from the Building Regulations on this page, however if it is not sufficient, you can either buy your own copy of this part of SANS i.
You will need to approach your local authority if you want a building inspector to take a look at the roof, or alternatively get an independent roofing specialist in. I am designing a single bedroom, lounge, kitchen, timber dwelling and was wondering on the following? Hi Balerit, Any one of the better timber merchants and or roof truss manufacturers will have those specs to hand. MiTek truss manufacturers are national and you can find their contact numbers here: mii.
Hi Stephen, There is no set standard amongst the municipal councils in SA when it comes to this situation, some want plans others not. The best I can suggest is you contact your local council planning department and find out what their rules are.
Hello, kindly advise me what the maximum height of a parapet is to be when using standard clay bricks and M concrete blocks? Hi Habat, The span can be as wide as the size of the beams will allow, but the wider you go the bigger the beam will be, the pitch of the roof will also need to be considered. A Structural Engineer or Architect will be able to advise you on your specific needs. Willem,flat roofs……brandering strips equi-spaced.
The authority in the municipality of your town can present you the SABS for authenticity. Message: Hi I would like to find out what it means when you are building with Grade 5 SA Pine, were doing an extention on our house with timber, it says they will use grade 5 sa pine timber, how do I know if they are using the correct timber. We have also had a lot of rain and our skeleton timber and roof trusses are wet, how long should one wait before you can start cladding the wood, and is grade 5 pine treated for getting wet.
Thanks Adele. I think you a referring to a UK product. Fibreglass is generally used for sheeting and is normally corrugated. Adele, all structural timber is graded according to specific SABS specifications. Grade 5 is for compression parallel to the grain of the wood. The grade mark is displayed on the timber which is usually CCA treated. The timber has no protection from water — which is why it should be covered on site. The problem with getting water on roof trusses is that they can warp.
They should dry out without too much of a problem, even if still damp when the tiles or sheeting are put on. Is it compulsory to have the plastic sheeting under the roof tiles for waterproofing? I have recently just bought a place and the geyser pipe burst and on inspection I noticed that there was no waterproofing or plastic sheeting under the roof tiles? NOTE The entire area of jurisdiction of any local authority, the area of which is cut by the line demarcating these coastal areas, is taken as falling within the coastal area.
I then inspected the last row of tiles, lifted them up and saw that the plastic sheeting below the tiles stops before the bricks, the plastic was also rolled up, looked like they were pushed back… With the last heavy rain theses areas with the rolled up plastic were filled with water and from the looks of it is running then down the wall between the brickworks. I have been told that the plastic is there to keep dust out and against heavy winds, but surely it must assist in times like my problem as well?
My questions: 1. Is this something that I can call the Builder or the Roof contractor back for to come and fix? Please assist me with a solution to my problem. Hello, i would like to ask what the appropriate size for timber wall plate is when using a currogated chromadek roof sheet on a pitched roof.
I just wanted to find out where one could train to Grade Structural Timber possibly a qualification of some sort. Would appreciate any help. I suggest you contact timber suppliers and ask if they know. Bukhali, All the specified timber sizes from the NBR are on this page. If it is not clear from this then I suggest you contact a Chromadek supplier and ask them. Alternatively contact Chromatek directly — they are based in Gauteng. Andries this looks like the same question asked a different way?
If an undertile membrane is properly laid it will provide a very effective, impermeable barrier against wind-driven rain and dust. For this reason this particular SANS states that underlays should be provided for all slate and tiled roofs, no matter what the pitch or slope , and where ceilings are not installed. I want to span a timber fascia for 7. The fascia is not a loading bearing member, and will only carry the gutter to collect water from an existing 7.
I have approved plans for the house with a normal gable roof with trusses. Now that I want to start building, I a m changing my mind about the whole. I want to build the house now and then later may be after 3 years get plans drawn to extend it higher into a double story house.
So I am gonna reinforce the foundations with steel and the will use M blocks for outside walls and M for partitions and will get the engineer to check every thing. Detailing of concrete roof tiles is the focus of section 4 of the Concrete Roof Tiles: Technical Manual, while section 5 covers timber roof construction. In South Africa, under the National Building Regulations, there are only two legal methods by which to design and construct timber roofs:.
Tacit approval has been given by municipalities in general to pre-fabricated truss manufacturers who use a suite of design programmes supplied by system suppliers to design roofs up to 10m in span for non public buildings.
Most of these system suppliers have been accredited. Also discussed in the timber roof construction section is timber quality; timber specification; timber treatment; storage of timber; roof pitch and wind forces; undertile membrane for roof tiles; factory engineered trusses; site manufactured trusses; erection of trusses; the use of rafters as roof supports; and fixing of battens.
This article cannot cover all the facets and requirements of good roofing practice. However, the Concrete Roof Tiles: Technical Manual issued by the Concrete Manufacturers Association CMA does, and is an invaluable guide for ensuring that roofs are correctly and safely installed and erected, and that they remain functional for many, many years.
We suggest you download the manual or, alternatively, get in touch with the CMA on Email: [email protected].
