Roof Leaks

Common Causes Of Roof Leaks

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.

Roof Ridges

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.

Valleys and Flashings

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

How Much Does Damp Proofing Cost?

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 – R730.00 per square meter.
  • Interior Rising Damp More Than 10m – R680.00 per square meter.
  • Exterior Rising Damp Less Than 10m – R600.00 per square meter.
  • Exterior Rising Damp More Than 10m – R520.00 per square meter.

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.

If you do have damp in your home and you have questions, please do not hesitate to contact our damp proofing team. We will happily assist you with any queries you might have. We are a 4th generation waterproofing and damp proofing business so we have seen it all!

Waterproofing Options

3 Common Waterproofing Systems For Your Project

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.
