The Importance Of Roof Maintenance

Roof maintenance should be every building owner’s priority. Waterproofing materials can not last indefinitely. Additionally, if the current waterproofing is not care for and maintenance, its life expectancy will be drastically reduced. 

South African climate is harsh. We experience tremendous changes in temperature. We sometimes experience high quantities of sunlight and ultraviolet rays, a long with strong winds and heavy rain or hail storms. Thus, regular attention to all exposed roof waterproofing systems is a must. Although, often overlooked. 

This responsibility should lie not only with the building owner but also with the original waterproofing contractor committed to advising the building owner when his roof maintenance is due. This regular maintenance extends the life of the system whether under guarantee or not.

Although some waterproofing manufacturers of bituminous membranes state it is not necessary to apply any protective coating to their membranes,  the norm is to initially apply at least one if not two coats of bituminous aluminium paint. The location of the roof will depend on how often a maintenance repaint is required.

In an industrial area where there is a lot of pollution, it might be necessary to repaint every one to two years.

Whereas in more rural areas, every four to five years might suffice. However, the industry ‘norm’ is every three years.

Top 5 Questions To Ask Your Waterproofing Contractor

Hiring a professional waterproofing contractor can be very costly but a worthwhile investment if done by an experienced waterproofing specialist. Make sure you ask the right questions to ensure you hire the right waterproofing specialist.

Have You Ever Had A Waterproofing System Failure?

Now, any waterproofing contractor that has been in the industry for a decent amount of time has had some sort of waterproofing failure, guaranteed. What you are looking for when asking this question is for the waterproofing contractor to say ‘Yes, I have’ and then further detailing why it failed and what they did to accommodate the client. First class client service doesn’t come from being the best and never making mistakes, it comes from HOW you manage your clients regardless of the circumstances.

Do Your Employees Have Insurance?

This is one of the most important questions to ask. You can be held responsible for any injuries that occur on your premises. The waterproofing contractor must have proper insurance and liability for their employees. Do not be afraid to request a valid workers compensation certificate and proof of public liability.

Will This Solution Rectify The Cause Of The Problem Or Just The Symptoms?

There are many symptoms to roof leaks, poorly waterproofed areas, lack of damp proofing course etc. You want to ensure that the solution that the waterproofing specialist is quoting you on is going to solve the CAUSE of your problem and not just remedy the symptoms of the problem. It is a surprise how often this occurs.

What Kind Of Materials Will You Use?

Even if you have no clue about waterproofing products, ask this question anyway. The waterproofing professional should be very well-versed in the different waterproofing products and systems available.

What Kind Of Guarantee Will You Offer?

This is definitely a no brainer. If you are going to pay a premium on waterproofing, you should always be offered a guarantee by the waterproofing contractor. Don’t be afraid to question the fine print in the guarantee terms and conditions as well. If you are paying for what looks like great quality products and services, there should be no question as to whether or not you will receive a guarantee certificate.

 

Your home or office is a treasured asset. Therefore, it’s important to be thorough in your research when choosing a professional waterproofing expert. Make sure you choose a waterproofing contractor that has your best interest in mind. Additionally, they should be committed to solving your problem.

Roof painting cost in Gauteng does not need to be expensive. And it shouldn’t be.

Although roof painting can be a time-consuming project. It requires skill and experience with roof painting products and technique.

However, because our roof painting projects are applied by means of airless spray machines, operated by highly trained employees, the cost of roof painting is not expensive.

So, How Much Does Roof Painting Cost?

For a small residential roof, you can expect to pay R105 per sqm. This includes washing down your roof prior to 2 coats of roof paint (colour of your choice).

For a larger, industrial roof, you can expect to pay R85 per sqm. This is subject to how large the roof area is.

 

Advantages Of Roof Painting

A fresh coat of high quality roof paint on your roof increases the value of your property. It also helps with the ergo dynamics of a building.

The roof colour you choose also makes a difference to the style of your building and how well it retains and reflects heat. For example, a dark charcoal colour roof will absorb a lot of heat, whereas a white roof is the coolest as it reflects the most heat.

There is a wide choice of paint products and techniques thanks to the advances in paint technology in today’s age. The roof paint products we use are durable and are of superior quality.

We receive a lot of enquiries regarding basement waterproofing or sub-ground waterproofing. Very few waterproofing companies specialize in basement waterproofing because it is finicky work and requires advanced experience.

However, we love basement waterproofing purely because we have mastered the skills and techniques required for sub-ground waterproofing.

We offer written guarantees for all our basement projects. Additionally, we advice you which system is best suited for your current water ingress situation.

 

What Causes Your Basement To Leak?

• Incorrect design from building stage.
• Excessively high water table and hydrostatic pressure.
• Damaged waterproofing on external walls.
• Root growth or structural movement.
• Inadequate subsoil drainage.
• Blocked or failed subsoil drainage.

 

Symptoms Of Your Basement Leaking

• The most obvious symptom is water seepage through the wall floor joints. This is the open joint where your masonry meets the concrete.
• Damp and muggy feeling inside the room.
• Mould smell or growth.
• Bubbling paint.
• Efflorescence or salts visible on walls.
• Lifting floor tiles (if any).

 

Basement Waterproofing Recommendations

If your basement leaks once or twice a year during a multi-day long down pour, you can tank the basement and waterproof it from the inside relatively easily.

However, if it leaks through normal Gauteng flash storms, we advise installing external subsoil drainage or an internal sump pump as an artillery measure to deal with the water.

 

My Basement Is Leaking. What Now?

The cheapest option and first point of call is to look at drainage in the vicinity. This alone may alleviate the problem entirely, depending on the severity of the leak.

However, if you have a sump pump or subsoil drainage, your best option is known as tanking. This is an application of waterproof, structural slurry capable of withstanding high levels of negative water pressure. Therefore, this is a highly effective system when installed correctly.

 

What Not To Do When Your Basement Leaks

• Do not apply a paint on ‘damp proofing’ or ‘waterproofing’ paint to the internal walls.
• Drilling holes in the wall to drain water out the room will only make it worse.
• Don’t apply any system onto the painted walls or floors.
• Selling your house is not necessary as this is completely salvageable.

 

We have successfully solved many basement waterproofing problems. If you have any other questions or concerns you would like to ask us, don’t hesitate to get in touch with our basement waterproofing specialists.

What is Rising Damp?

Rising damp can be defined as moisture which rises up from the ground and travels upwards in the masonry of the building structure by means of capillary action. This moisture dries out on the wall surface and can present itself in various unsightly forms such as paint failure, discolouration and mould growth.

Capillaries are very narrow passages or tubes which occur in masonry. Capillary action is when moisture rises up in these tiny passages even against the force gravity.

The foundations of a standard dwelling are generally constructed of concrete laid onto compacted soil. Brick work, usually between 5 and 8 courses high is built on top of the concrete foundation. Do you want to know how much rising damp treatment costs? Read our article here, ‘How Much Does Damp Proofing Cost?’

A DPC (Damp Proof Course) usually consisting of a heavy-duty plastic layer is loose laid onto this. The rest of the wall is built on top of this plastic DPC layer. The section of brickwork between the foundation and DPC is designed to be a “wet zone.” The DPC is designed to prevent water from rising up beyond this wet zone. However, when various factors develop and the DPC is comprised, then rising damp can take place.

 

What Are The Signs Of Rising Damp?

Rising damp can occur to interior and exterior walls and usually presents in the lower portion of the wall typically up to a height of 1m. It is rare for rising damp to be higher than 1,2m.

However factors such as tile cladding or a waterproof plaster applied to lower section of walls without installation of a chemical DPC can cause this occurrence.

The use of a moisture meter is sometimes used by professionals to detect rising damp, but usually the signs are very obvious and is not a necessary tool.

There is moisture in walls naturally so using a moisture meter is almost always guaranteed to pick up moisture.

 

Signs and symptoms include the following:

• Paint failure characterised by blistering and bubbling of the paint film.
• Brown or darker stains or “tide” marks to the wall surfaces which is blemishes due to moisture in the wall.
• Wall surfaces feel cold and clammy.
• White powdery deposits on the wall surfaces, technically termed salts or efflorescence.
• Crumbling and failure of plaster.
• Rotting or warped skirting boards.
• Mould smell which could be occurring under skirtings or carpets and is often is triggered by damp in walls.
• Peeling or discoloration of wallpaper.
• Rooms feel unusually cold in the winter months.
• Mould on wall surfaces which is usually black in colour, but can also be brown, red, green and yellow.

 

What Causes It?

There are many possible causes of rising damp and these include the following:

• DPC non existent, degraded or failed or is incorrectly positioned.
• Moisture bypasses DPC via plaster from wet zone area.
• Wall below DPC has been plastered and painted, which traps moisture inside the wall.
• Excessive exposure of walls to rain due to design of house with no eaves or roofs with no gutters.
• Ground level higher on other side of wall which breaches DPC.
• Wooden floors which been removed and replaced with concrete.

 

What Are The Detrimental Effects Of Rising Damp?

There are numerous adverse effects of rising damp. These would typically include the following:

• Unsightliness. Paint failure occurs very quickly when rising damp is present and negatively impacts on the aesthetics of the building structure.
• Devaluation of property. Buyers seldom want to purchase buildings which are damp affected.
• Moisture in walls reduces insulation properties and makes buildings much colder in the winter months.
• Damp in walls can trigger mould growth which has bad odour and is detrimental to health.
• Rising damp can cause damage to property, especially to interior walls, including rotting of skirtings and carpets and rusting of metal door frames and electrical plug sockets.

Derbit SA. Their aim is to be the reference provider of sustainable solutions that safeguard buildings from the elements of nature. A company that has changed the face of waterproofing in South Africa. A company that provides products of only the absolute highest quality. And we are fortunate enough to say we are PROUDLY a Derbit Approved Applicators.

Our Story With Derbit

It all began on a busy waterproofing day when Richie got a phone call from a lady, Carlize, from Derbit SA. She wanted to meet up to discuss their product range. Of course, we had heard of Derbit and Derbigum before, so Richie booked an appointment. Thereafter, our relationship only grew as we order their torch on waterproofing on a weekly basis.

Our waterproofing team (who have dealt with various torch on waterproofing systems over the years) brag to other waterproofing companies how incredible Derbit torch on waterproofing is. The mastic that oozes from the torch on upon heat fusion is something out of a fairy tale waterproofing movie! (Mastic is what helps to secure the torch on to the surface. Lots of sticky mastic = quality waterproofing)

Since Apex Waterproofing’s mission is to offer quality waterproofing services with 5 star client relations, we only use the best of the best. Derbit is considered one of the more expensive waterproofing brand names but they offer incredible quality and durability. If your preferred waterproofing contractor quotes new torch on or torch on maintenance, ask what brand of torch will be used. This is a clear indication of what type of waterproofing service provider you are dealing with.

Derbit’s approved applicator system is by no means easy. It requires project assessments and client follow ups on several different past projects.

We are proud to support them and to be one of the few approved applicators in South Africa.

How to fix damp walls South Africa? Damp proofing is a skilled trade and should not be considered a DIY practice.

Damp is the unwanted presence of moisture within a structure, whether on the exterior or interior of the building. It can be caused by different aspects such as leaking plumbing pipes, rising damp, water ingress from roofs or window sills and condensation.

How To Fix Damp Walls In South Africa

Damp proofing works as a long-term prevention of unwanted moisture. Damp treatment is NOT as simple as scraping off loose and flaking paint and coating with a product from your nearest hardware.

There are various types of damp. If the damp is not found at the base of the wall and is situated above eye-level then it is not rising damp.

The area around the damp would then need to be inspected to investigate the cause. It could be a leaking downpipe, roof leak, plumbing, balcony leak or even a small crack on the exterior of the wall.

How Do I Know If My Home Has Rising Damp Treatment?

When a building is in the construction phase, a damp proofing course should be installed at the base of the walls. Either by a specialised waterproofing or damp proofing contractor. Damp proofing and waterproofing in new builds is only 1.5% of the entire building cost. It is not an unnecessary purchase that many building contractors make it out to be.

If you want your property to last as long as what it should, do NOT skip out on proper waterproofing and damp proofing. If damp is found at the base of your walls, then it is likely rising damp. That means either there is no damp proofing course. Or there has been damage to the foundation where the damp proofing course has been installed.

Roof leaks are every homeowners worst nightmare. No one wants to fork out thousands to get fix their roof. It is what we like to call a ‘guilt purchase’. If the roof leaks are not discovered and repaired quickly, it can cause immense damage to the building structure. Here is a list of roofing aspects we think you should consider with roof leaks:

Dirt And Debris Build-Up

If you have a lot of overhanging trees by your rooftop or you see a lot of debris on your roof, call a roof repair specialist to come and clean and inspect your roof. It is important to keep your roof clean to permit adequate waterflow. Even if you do not notice any roof leaks, we suggest you have your roof inspected anyway.

Gutters And Downpipes

This goes hand in hand with item 1 above. Blocked gutters or down pipes will cause a water backlog. Thus, water will find its way under your roof tiles or metal sheets, causing internal leaks. Ensure your gutters are clean and are in good condition.

Roof Age

Roofs deteriorate overtime, that is inevitable. The older it gets, the less effective it becomes with keeping water out. South Africa is very prone to experiencing all 4 seasons in one day. This causes your roofs temperature to fluctuate often resulting in your roofing material to become brittle and crack or loose effectiveness. If your roof has not been inspected in more than 3 years, we strongly recommend you get your roof inspected ASAP. Roof leaks can occur for months before you see the symptoms in your interior space. But by that time, it is too late and the damage to your roofing structure has already been done.

Roof Ridges

Roof ridges are the highest point of the roof and covers the opening where the 2 roof planes meet. The roof ridges are normally joined with repair mortar which has a tendency to crack overtime. The tiny cracks result in roof leaks.

Chimneys

These little devils are the source of many roof leaks. Chimneys need to have specific flashings properly installed and the counter-flashing that goes into the brick mortar needs to be perfect. If not, you will have roof leaks guaranteed. Small hairline cracks often occur which causes major water ingress, especially in our heavy Johannesburg storms.

Valleys And Flashings

Valleys are long metal sheets that run up and down the intersection where two roofs meet. Roof flashings are metal sheets that are installed where objects or extra builds protrude from the roof. It prevents water from entering joints and causing roof leaks. If these vital aspects have holes or are not joined correctly, it will cause major roof leaks and damage.

Uneven or Unlevelled Surfaces

If you have a flat concrete roof that is not even or slopping slightly towards a downpipe, you will experience water ponding. Roofs are not designed to hold the weight of water so ponding will cause major roof damage if not corrected. Long periods of ponding can also create a build-up of silt. Silt is like tiny grains of sand and soil that start to break down the waterproofing on the flat roof. Thus, causing roof leaks.

Damp proofing cost are based on a number of factors as damp proofing treatment can be very broad depending on what sort of damp it is.

 

Our Rising Damp Cost Factors Include:

• Firstly, is it rising damp? If not, what sort of damp is it?
• How many meters of damp need to be treated?
• Are there any obstructions in the way of installing the damp treatment? (ie. windows, plugs, wall mounted items etc)
• Is it a simple wall or are there permanent wall mounted objects that would need to be broken and removed and carted off site?
• Is the damp accessible? We have had cases in the past where our team had to squeeze through a tiny gap under the bathroom basin cupboard in order to treat the rising damp on the wall.

With the above factors in mind, you can expect to pay the following for rising damp treatment:

• Interior Rising Damp Less Than 10m – R1,200.00 per meter.
• Interior Rising Damp More Than 10m – R1,000.00 per meter.
• Exterior Rising Damp Less Than 10m – R890.00 per meter.
• Exterior Rising Damp More Than 10m – R860.00 per meter.

These prices are a rough indication and exclude painting and rhinolite.

If you want to confirm that you do in fact have rising damp, read our article ‘Rising Damp Explained‘ here.

 

What If It Is Not Rising Damp?

If the damp problems are not rising damp at all then a comprehensive investigation would need to be scheduled by our trained damp proofing team to determine what the cause the damp is. Damp can be caused by tiled roof leaks, flat roof leaks, leaking window sills, plumbing pipes, cracked exterior wall, leaking down pipes and more. For more information on damp, see our damp proofing page.

Waterproofing systems are critical to have. A simple leakage in a building roof can often result into serious problems, not only causing damage to the building’s structure but can also be very expensive to fix.  Leaks can be mended with efficient waterproofing techniques done by a professional waterproofing company.

This ensures that water cannot penetrate through the roof of the building. The best and most cost-effective solution is prevention. Through durable sealing and applying of waterproof coatings, water intrusion can be prevented, eliminating water damage.

Consult with a roof waterproofing expert who will know the most effective waterproofing method to use for each application.

Sheet membranes and Liquid membranes are mostly used for implementing water protection for roofs. Let’s take a closer look at these three waterproofing systems.

Waterproofing Options:

Sheet Membrane Waterproofing (AKA Torch On Waterproofing)

Using high quality adhesive, sheet membranes may be cold applied or with the help of a torch. When done right, sheet membrane provides a durable and long-lasting waterproofing solution. Sheet membranes are good to apply to almost all horizontal areas that require waterproofing. They are usually high performance and non-hazardous.

Liquid Membrane Waterproofing

Liquid waterproofing membranes delivers an excellent waterproofing solution that is applicable to small or very detailed areas. It is ideal for wet areas, very easy to apply, resistant to UV rays and not harmful to the environment. A great advantage of using liquid membranes is that it creates a fully bonded, protective seal, this ensures that no water will enter beneath the membrane.

Epoxy Waterproofing

Epoxy is a type of resin adhesive membrane that dries hard, shiny, and smooth. Applying several coats of this can result in a water-proof or water-resistant surface. It is designed to be used as seamless waterproof membrane to protect concrete from water damage as well as resistant to bacteria and moisture due to its seamless nature. But epoxy waterproofing is rigid (not flexible) and may break when there are movements in the building elements due to thermal expansion and contractions.

What Is Important To Note

Roof waterproofing prevents damage to the roof and structure caused by water. Little attention is paid to the waterproofing as it ends up being hidden, when it fails it results in a very expensive repair.

In order to prolong the life span of a building structure and prevent damage, waterproofing methods must be properly applied by waterproofing specialists.
