Roof Repairs in Cape Town – Preparing for the Stormy Season

Winter is just around the corner, and for many homeowners in the Western Cape, that means investing in Cape Town roof repairs. This year, instead of waiting to see whether any damp or water damage occurs, get proactive with a simple yet effective three step check that will go a long way in preventing little problems from becoming big, expensive problems.

It is no secret that winters in this part of South Africa bring their share of wind, rain, hail and other harsh conditions. The city did not get its nickname ‘The Cape of Storms’ for nothing, after all. Whether you live on the coast or further inland, preparing for the wet weather will go a long way in preventing drips, leaks, flooding, damp and other related issues.

Roof Repair Checklist to Prepare for Winter

Don’t wait until you urgently need emergency roof repair. Some of the most important things to check include the following:

  • Gutters

Servest Box Gutter Repairs 1From late autumn all the way to late spring, Cape Town receives a high percentage of rain. One of the biggest causes of damp is blocked gutters that cause water to pool on the roof. Gutters and downpipes that are filled with leaves, branches and other debris are unable to channel water properly. As such, these fittings should be thoroughly checked and cleaned before each season to ensure that they are free of debris. It is best to leave this to the experts, who have the necessary equipment and skill to do a proper inspection and clean. If repairs are needed, they will be able to assist with these, too. They will also check that gutters are secured to the roof, and free of rust and damage.

  • Roof Tiles

roof tilesWhether you have an older home with a shingle roof, or a newer home with a modern flat roof, damaged, missing or shifted roof tiles are the quickest way to allow water to sneak inside your house. You may be able to see signs of damage from the ground, but unless you have experience in roof related repairs, it is best to leave more extensive checks to the professionals. They will be able to safely get onto the roof, know where to step (and where not to step!), what to look for and what to do when any problems are noted.

  • Flashing

Flashing that is rusted, worn, cracked, warped or otherwise damaged can also greatly affect the overall longevity of your roof. This is one of the biggest causes of water leaks in roofs – hail, strong rain, wind and heat can all affect flashing over time. After a long, dry, hot summer, it is a good idea to check that all flashing is in good shape and able to withstand the storms to come. If any signs of damage or wear are found, it is essential to replace flashing quickly.

Which Roof Repairs Will You Need Before Winter?

If you are considering roof repair in Transkei or any other part of South Africa, now is a good time to start planning. While the Wild Coast may be blessed with a mild temperate climate and fairly calm winters, the cooler time of year can bring winds and rain from time to time. Planning your roof maintenance, repair or renovation at the end of summer will ensure that you have ample time to prepare for the winter months. And, with much of the country still facing drought conditions, this is an especially good time to sort out any roofing issues you may have.

roof repair

Roofing projects are not only limited to dealing with problems however. There are many different types of repairs and renovation that may fall under this service, each offering its own benefits and goals. In this article, we take a look at some of the most common services that fall under roofing work.

Choosing the Right Type of Roof Repair in Transkei

Depending on your specific needs, and the current state of your roof, you could choose one or more of these Transkei roof repair services…

  • Waterproofing. Low pitch roofs require special waterproofing, but regular pitch roofs may also require work to fix holes or leaks. As this type of job requires professional assistance, it is essential to consult a roofing or waterproofing expert if you have experienced any leaks or damp patches coming from a damp or damaged roof. Attempting to fix it yourself can be dangerous. If you are not sure exactly what to look for or where it is safe to walk on the roof, or even where to safely climb up and down using a ladder, do not risk your safety. A professional will get the leak sorted quickly and simply, saving you time, effort and ultimately, money.
  • Roof Tile Restoration. Sometimes, over time, wear and tear may cause damage to one or more roof tiles. Specific types of tiles have their own properties, such as clay Dek-tile or other varieties of natural or man-made tile materials. As such, the restoration of a tiled roof will depend entirely on the type of tiles your roof contains. The age of your house will also affect how simple or extensive this type of job will be. In some cases, you may choose to upgrade older clay tiles to a modern alternative, or in other cases, you may want to refurbish older tiles to prevent further damage.
  • Metal Roof Refurbishment. If you have a corrugated metal, aluminium or asbestos sheet metal roof, you will require a roofing expert who is equipped to handle such material. Asbestos roof repair requires an accredited repair specialist and cannot be done by laymen. If you wish to add on to your garage or shed, or replace an old metal roof with a newer one, remove an asbestos roof or repair any holes or damage within the roof, it is best to consult an experienced expert who has a solid understanding of this type of roof.
  • Roof Cooling. Infra-red roof cooling technology was once limited to the air force and related industries, who used this special paint to make ‘invisible’ planes that could not be detected by heat sensors. Today, it is used to cool buildings by blocking the sun’s rays. Various colours are offered in our roof cool coating range, giving you the benefit of a freshly painted roof that does not retain heat. View our infra-red roof cooling page for more information about this product.
  • Roof Coating. For all other types of roof paint, coating options can be done according to your preferences and needs. For older roofs that require a new coat of paint, or roofs in high sun areas that have faded prematurely, this cosmetic job is also a good way to extend the life of roof tiles and protect your roof against damp and rot.

Whatever your roof repair needs may be, you are sure to find the help you need at Wilcote. Contact us today to tell us how we can help you get your roof ready for the upcoming winter.

5 Things to Know About Asbestos Roof Repair

Asbestos roof repair in Mpumalanga and the rest of South Africa typically applies to any work done on roofs that contain asbestos. As this hazardous material has been banned in SA, only certified asbestos removal specialists are allowed to repair, remove or handle the substance. If you have an older property that is fitted with an asbestos roof, this means that is better to call in a professional to help you get your roof fixed safely and simply.

Once considered to be a miracle substance in the 19th Century, asbestos is comprised of a number of naturally occurring silicates. Originally, this material was popular for its economic advantages, along with its sound absorption, tensile strength and its fire, heat, electrical and chemical damage resistance. At one point, it was widely used in automotive, marine, construction and scientific industries, for a variety of purposes. Over time however, studies began to show that prolonged inhalation of asbestos fibres was linked to serious illnesses, which include lung cancer, mesothelioma and asbestosis.

damages-asbestos-roof-fibres

It is this potentially deadly risk of exposure to the fibres that has led to the ban of the material all over the world. But, as many older buildings still have asbestos roofs, repairs are inevitable. Complete removal or replacement of the roof is not always a viable option, which is where specialist contractors come in to help.

What exactly is asbestos, and more importantly, what should you know about repairing a roof that contains this material? Keep reading to find out.

Everything You Should Know About Asbestos Roof Repair in Mpumalanga

Some of the most important things to note about this sort of roof repair include the following:

  1. Asbestos can some major health risks. Asbestos fibres that are inhaled into the lungs can cause major diseases, including asbestosis (scarring of the lung), lung cancer and mesothelioma (tumour growing on the lining of the lung). Early symptoms could include chest pain and shortness of breath, with respiratory failure, cardiac arrest and death becoming a risk at later stages. It may take anywhere from 15 to 50 years for symptoms to develop, from the very first contact with the fibre. No symptoms are experienced during this dormant period, and there is no cure for asbestos related illness.
  1. Illnesses are not always reported in SA. The World Health Organization (WHO) estimates over 100 000 asbestos related deaths per year world-wide, with 125 million workers exposed to fibre around the world. In South Africa, some 200 mesothelioma cases are reported annually, but, due to the large size of the construction and mining sectors and the fact that SA was once a major exporter of the material, many more cases are believed to be unreported.
  1. It is not a good idea to handle asbestos without authorisation. Unless you are authorised to provide asbestos removal services, it is illegal and dangerous to attempt asbestos roof repair in Mpumalanga or anywhere else in South Africa. If you discover any signs that the roof may contain asbestos fibres, or you are not fully sure what the roof is made from, it is safer to call in a specialist to assist.
  1. Exposure is a risk when fibres are released into the air. If fibres are contained within the structure of the roof, the risk is minimised or even reduced completely. But due to the high risk nature of this material, repairs may not be conducted on any roof that contains asbestos – hammering, high pressure cleaning, drilling, cutting, patching and walking on roof tiles can all release fibres into the air.
  1. When in doubt, play it safe. If you have an older property and you are not certain whether asbestos is present in the roof or not, it is safer to proceed with caution. Contact an approved contractor who can safely repair your roof using the proper methods and equipment.

Why Hire a Roofing Contractor in Fourways This Summer?

With a hot, wet summer ahead for much of the Gauteng area, hiring a roofing contractor in Fourways is essential to ensure that you are prepared for those epic storms. While many parts of South Africa have their rain during the winter months, Gauteng is famous for its summer rains. This is great to balance out the hot temperatures, but not so great when it comes to preventing leaks, drips and other roof problems.

Now is the time to get your roof ready for summer – whether you need a simple check to see that everything is still in good condition after winter and spring, or you have specific issues that you wish to get sorted before the weather starts to heat up.

Roofing solutions

Getting Summer Ready with Fourways Roofing Contractors

There are many things that a fairly competent DIY enthusiast can tackle. Fixing and assessing roofs however is not one of them; unless you are an experienced, qualified roofing specialist. With this in mind, one of the simplest and most effective ways to get the job done properly (without the risk of even more problems further down the line) is to bring in someone who has been trained to take on specialist tasks, such as Fourways roofing contractors with sufficient expertise in summer roof preparation, repair and maintenance.

Some of the benefits of outsourcing this job include the following:

  • Storm proofing. Even the smallest hole or broken patch on a roof can lead to very serious, very expensive damage in a storm. When the rain comes down hard, your roof needs to be fully proofed against storms to ensure that water has no chance to get in anywhere.
  • Safety first. As we mentioned just now, attempting to fix or examine your own roof is not the best idea. Accidents are caused by inexperience in many cases, and unless you have built up ample experience and expertise in getting on and off roofs, walking on roofs and checking roofs safely and properly, it is far safer to call in a specialist
  • Long-term investment. Seasonal or bi-annual roof checks are a great way to ensure that your property remains in good condition throughout the year. Your property is, after all, an investment. As such, you need to look after it to get long-term rewards. This way, small problems can be spotted and fixed right away, instead of being overlooked and turned into bigger, more expensive disasters.

As you get ready for the upcoming summer months, holiday season and year-end festivities, make sure that your roof is also ready for the hot, rainy months ahead.

With the help of qualified, trusted roofing contractors in Fourways, such as Wilcote, you’ll have one less thing to worry about while you wind down to the end of year.

TSR Levels on Infra-Red Cool Coating

One of the many roofing services that we offer here at Wilcote is infra-red cool coating, which is an innovative technology that helps to provide cooling to buildings and structures. This technology has been proven to be extremely effective in preventing urban ‘heat islands’ – an occurrence that is caused by the sun’s rays reflecting on manmade surfaces such as roofs, which in turn results in increased temperatures.

A very important part in the effective usage of infra-red roof cooling lies in ensuring that products and technology used in the process meets certain standards. TSR (Total Solar Reflectance) measurements are used to meet these standards, and measure the amount of solar radiation that is reflected by the sun.

Before we discuss TSR levels and their importance, it is first a good idea to understand exactly why infra-red coating for roof cooling is becoming essential in our cities and towns.

Temperature increases in densely populated areas is thought to be caused by air pollution to some degree, but the sun’s rays that are absorbed by buildings also plays a major role in this heating process. The light reflectance value of roof coatings and paints used on buildings has a direct effect on how these rays are absorbed. Technology suchas infra-red has been successfully used in many different instances, but in the paint and roofing industry, it has proven to have significant impact on reducing the amount of heat absorbed by coated surfaces.

cool-roof-energy-saving

What Are TSR Measurements?

Simply put, Total Solar Reflectance (TSR) uses a percentage or decimal figure to show the amount of infra-red radiation that is reflected from a surface, such as a roof. The higher the TSR level, the higher the reflectance. Roofing companies and paint and coating manufacturers need to be aware of these levels before they are able to make claims on how much light can be reflected by the products they offer. Light reflectance levels are measured through visible and invisible colour spectrums – particularly the infra-red spectrum where light is absorbed. Needless to say, it is impossible to measure such levels by the human eye. Instead, special measurement tools are used.

Through the use of standards that govern TSR measurements, and the use of colour measurement tools that allow these levels to be accurately measured, it is possible to determine the exact value of TSR in roof coating products. These measurements are based on US standards that differ from SABS standards used in South Africa.

Measuring tools include the Solar Spectrum Reflectometer, which features a selectable solar measurement spectrum that correlates to standard global and beam normal solar irradiance models. This tool delivers accurate measurements on various materials, including surface reflectors as thick as 6.4mm. Solar reflectance or absorptance is shown to 0.001 units, with a 0.003 unit repeatability.

How Do TSR Levels Affect Infra-Red Cool Coating Products?

TSR levels on all Wilcote infra-red cool coat products meet the following US standards:

  • ASTM C1549. Standard Test Method for Determination of Solar Reflectance Near Ambient Temperature Using a Portable Solar Reflectometer.
  • ASTM E903. Standard Test Method for Solar Absorptance, Reflectance, and Transmittance of Materials Using Integrating Spheres.
  • ASTM E891. Tables for Terrestrial Direct Normal Solar Spectral Irradiance Tables for Air Mass 1.5.

3 Things to Remember When Sourcing Roof Repairs in the Cape Winelands

With winter in full swing throughout much of South Africa, roof repairs in the Cape Winelands are certainly something to consider. Strong rains, wind, hail and storms can wreak a fair amount of havoc on your roof – especially in older homes. Horror stories about roofs being blown away at night aside, there are a few things that can go wrong when it comes to the roof. Leaks are one of the most common issues, but an old or tatty roof can also look less than appealing, result in more drafts and even increase your energy consumption if it is interfering with the house’s ability to retain heat.

The good news is that many roof problems can be prevented entirely if you stick to a regular schedule of inspections and upkeep.

Paarl-panorama_300dpi

Top Tips for Roof Repairs in the Western Cape Winelands

Some of the most important tips to remember when it comes to Winelands roof repair include the following:

  1. Maintenance is the best way to prevent problems. At least once a year (before winter is usually the best time), call in a roofing expert to do a proper inspection or make sure that basic steps are taken to prevent problems from arising. Clean ventilation systems and vents, caulk around openings with a high quality sealant, paint any exposed metal to prevent rust, clean out gutters and check from the ground to see if anything looks out of place. Use binoculars if you want a better look, but try not to climb onto the roof unless you have plenty of experience in this regard. This routine check can help spot small problems, before they become bigger, more expensive problems.
  2. When to call in the experts. Doing a visual inspection over the course of the year is essential, but if you notice any problems such as stains on the shingles, missing parts of the roof, rusted flashings or anything else that seems amiss, call in for help. The same applies if you notice any water stains or mould in the attic or on the roof, or if there are any leaks on second story ceilings or unexplained damp patches in the ceiling.
  3. Investing in the best quality roof will help it last far longer. Another step that is recommended is to focus on getting the best repairs, materials and installation that is within your budget. If the roof is installed by a qualified expert, using high quality materials and coating, you will be able to rest easier knowing that it will last you through many years to come.

If all else fails, hiring a dedicated, professional expert to assist with roof repairs in Winelands will go a long way in ensuring that the roof is fixed quickly, properly and simply.

Port Elizabeth Asbestos Roof Refurbishment

Wilcote Port Elizabeth have been awarded the Phase II contract, (after the successful completion of phase I) for the Asbestos Roof Refurbishment at their bottling plant at Coca Cola Lakeside in Port Elizabeth.

 The process of refurbishing Asbestos Roofs involves firstly washing the roof down with an Eco Friendly Special Asbestos cleaning chemical in order to remove the algae and lichen growth. Because the process is a “wet process” the chances of releasing asbestos fibres into the air are minimal as we also fit asbestos filters to all rainwater downpipes. The Asbestos Regulations do however require the air to be monitored during this process of washing the roof down. The method of monitoring the air is by fitting air pumps at either end of the roof and one pump is fitted a staff member. The gauze grids on the inside of the pumps are sent to a laboratory for inspection and counting of the number of Asbestos Fibres contained therein.

 Once the roof has been thoroughly cleaned down and has dried an Asbestos Encapsulation is applied by Airless Sprayer onto the roof sheets. This process binds any loose Asbestos Fibres which may have been loosened during the cleaning process and then renders the the Roof 100% safe. The roof is then ready to be waterproofed.

 The waterproofing layer consists of the application of our Elastomeric Sealer which is applied by airless sprayer at the rate of one square metre per litre. This waterproofing layer effectively seals all hairline cracks, which tend to occur in older asbestos roof sheets and makes the roof waterproof. Because the product is designed to be elastic it expands and contracts with the roof sheets as they heat up and cool down by the ambient weather conditions. Immediately after this layer has been applied the roofing screws are sealed with Wilcote non-hardening Crack and Hole Filler. This product too has very good expansion and retraction properties and, very effectively, seals the roofing screws preventing ingress of any moisture.

 The final step of the refurbishment process is the application of the top coat. This top coat is part of our latest Technology Development in Solar Reflection where the infra red rays are reflected back up by the coating. This means that the roof sheets are kept at a cooler temperature than with normal roof coating which in turn means a saving in energy costs.

This whole process is cheaper than replacing the roof with one of the many types of metal roof sheets available and the real plus is that the refurbishment will not interfere with the day to day activities taking place on the inside. If clients were worried by the effects of Asbestos on the staff and businesses these can now be forgotten.

 Wilcote offers a guarantee on the above asbestos roof repair system of 12 Years but longer guarantees are available upon request.

How to Choose Roofing Contractors in Mpumalanga

Whether you are based in the Highveld or the Lowveld, one thing remains the same – finding reliable roofing contractors in Mpumalanga is essential. Known for its varied climates, this South African province is blessed with astounding natural beauty and a staggering range of temperatures. Snow, rain, humidity, dryness, summer rain, wind and frost can all be found across the province’s various climatic regions. This is great for those who enjoy the beauty of the diverse province, but not so great when it comes to keeping your roof in shape.

All too often, most people find that they will only start searching for roof contractors after the roof has been damaged or when there is a storm or other event that causes problems. The problem with this strategy however is that the urgency of the situation can lead to the search being far more rushed than it should be. The last thing you want to deal with on top of roof problems is a contractor who does not know what they are doing.

To help you make a choice that is less rushed and more informative, we have put together a few tips that will make the process far easier (and less stressful, too).

wilcote-roofingChoosing the Best Mpumalanga Roof Contractors

What do you need to look for when searching for roof contractors in Mpumalanga? There are a few things that you can check for that will make the search a lot more efficient. These include the following:

  • Make sure that the contractor is fully licensed and authorised. A certified roof expert will need to adhere to certain standards, which means that you will be able to trust that they get things done properly. It is tempting to pick a random roofing company on Gumtree or in the classifieds, but if they are not licensed to perform the work, you are instantly at risk of liability if anything goes wrong.
  • Ask for references or look for testimonials. Most good contractors will have testimonials on their website, and will be glad to provide references if needed. You could also do an online search to see if there are any reviews from previous customers. Good or bad, these reviews go a long way in helping you get an idea of what the contractor is all about.
  • Choose local wherever possible. A contractor who is based in your area (or at least in your province) will be a lot more reliable than one who is not. The reasons for this: they will know the area’s specific weather challenges, they will be easier to reach when you need them and they will have good knowledge of any zoning laws that may apply to your specific area.
  • Do not choose on price alone. Sure, cheap always good. But what is better is a job done right. It will not be much use getting a great deal on a roof replacement if the roof starts leaking a few weeks later. You may end up having to fork out far more trying to fix the mistakes done by the cheap contractor. Ideally, you want a good price AND a good service.
  • Start looking right now, before your roof needs help. This is something that will save you a great deal of time and stress in the long haul. Finding a reliable, experienced roof expert before emergency repairs are needed will mean that you know who to call immediately when anything goes wrong. If your roof is old, you may also find that a proper inspection could save you a fortune by spotting small problems before they become big problems.

As a qualified, fully certified company that operates across South Africa, Wilcote is your ideal choice for reliable roofing contractors in Mpumalanga. Contact us today for a quote, and let us know how we can assist.

Refurbishment of FNB Stanger

Wilcote was contracted to carry out the refurbishment and waterproofing of the FNB Building in Stanger. It was found that the Building was in desperate need of Refurbishment, as the existing roof and the exterior were in a poor state.

The waterproof system was a Torch-on System. We found the Protective Aluminum Silvakoting on the Torch-on, had started to deteriorate, from the harmful UV rays. In order to refurbish this roof we had to clean down the roof and attend to all problems areas of the Torch-on. Once this has been completed we then applied of our Wilcote Infra-Red Silvakote System.

The advantages of using the Wilcote Silvakote are as follows:

  • It carries a 5 year guarantee.
  • It reflects the harmful UV rays of the sun.
  • It reduces the internal temperatures of the building.

On the exterior of the building, we found that there was a large amount of cracks. We then recommend a full Exterior Decoration, this included opening and sealing up all cracks with our Soudal Polyurethane Sealant. This sealer has a two ton breaking strain and therefore prevents the cracks from re-appearing. We then also proceeded to seal all parapets with our Wilbond Parapet Sealer; this prevents water ingressing into the bank. Once this was completed we then painted the exterior with our W120 Infra-Red Cool Coating.

The advantages of using this system are:

  • All cracks are correctly sealed and don’t re-appear.
  • This system creates a waterproof casing, to ensure water doesn’t enter into the building.
  • The Infra-Red Cool Coating System prevents the deterioration of the pigment in the paint, to ensure a longer lifespan of the coating.

Tip of the day:

  • Ensure all flat roofs are coated regularly with protective coatings, to allow a longer life span of the waterproofing and avoid excessive costs in the long run.
  • Ensure that your building is correctly sealed to ensure no internal water damage and damp.

Granor Passi Roof Repairs in Polokwane

Granor Passi is a fruit juice and fruit juice concentrates manufacturer. It has four factories is Limpopo, and one in Cape Town with offices in Johannesburg. The main plant – which was the first factories here in Polokwane – was built between the 1940s and 1960s Due to the age of the plant, they have a lot of need for our services.

We have been doing maintenance and roof repair with Granor Passi in Polokwane for over 6 months now and they are very pleased with our work quality, reliability and response time to their ”emergencies”.

The roof we just did for them is over one of their many cold storage rooms. The roof was badly rusted and perforated in places. The solution I offered them was to restore the roof as we did their Workshop and Yoghurt roofs in May 2014. So in badly rusted areas where the rust has perforated the sheets, we cut those sheets (all the badly rusted areas were on the end laps) and fitted slip sheets extending 0.3m over the purlin.

 We treated the overlaps with WS4 and squeezed some soudal in the overlaps. We used descalex in places, then high pressure cleaned the roof then spot primed the roof and all the newly fitted sheets

 A final coat of W130 was sprayed over the roof. (W130 left over from the Yoghurt and Workshop roof).

 We have a very good working relationship with Granor Passi and number of jobs lined up with them for roof repairs and painting in Polokwane.
