Signs that your flat roof needs to be replaced

Over time, flat roofs can deteriorate due to various factors such as age, weather conditions, and improper installation. It’s important to be aware of the signs that indicate your flat roof may need to be replaced. Here are some key indicators to look out for:

  1. Persistent leaks: If you find yourself constantly dealing with leaks, even after repairs, it may be a sign that your flat roof has reached the end of its lifespan. Water infiltration can cause significant damage to your home’s interior, so addressing the issue promptly is crucial.
  1. Sagging or uneven areas: A flat roof should have a level surface. If you notice any areas that appear saggy or uneven, it could mean that the underlying structure has been compromised. This could be due to water damage or structural issues, and may require a complete roof replacement.
  1. Cracks and blistering: Cracks or blisters on the surface of your flat roof can indicate underlying damage or wear. These issues can lead to leaks and should be addressed promptly to prevent further damage.
  1. Excessive wear and tear: If your flat roof is showing signs of extensive wear and tear, such as loose or missing shingles, it may be time to consider a replacement. A worn-out roof is more prone to leaks and other issues, so investing in a new roof can save you money in the long run.

Replacing your flat roof at the right time can help prevent further damage to your home and ensure the safety and comfort of your family. Now that you know the signs to look out for, let’s explore the benefits of replacing your flat roof.

Types of flat roofing materials

When it comes to flat roof replacement, there are several types of materials to choose from. Each material has its own unique characteristics, advantages, and disadvantages. Here are some of the most common options:

  1. Built-up roofing (BUR): Built-up roofing consists of multiple layers of roofing felt, asphalt, and a protective surfacing material. BUR is known for its durability and longevity, making it a popular choice for flat roofs. However, it can be heavy and requires professional installation.
  1. Modified bitumen roofing: Modified bitumen roofing is a single-ply membrane that combines asphalt with rubber or plastic modifiers. It offers excellent resistance to extreme weather conditions and is relatively easy to install. However, it may not be as durable as some other options.
  1. Ethylene Propylene Diene Terpolymer (EPDM): EPDM is a synthetic rubber roofing membrane that is resistant to UV rays and extreme temperatures. It is easy to install and maintain, making it a cost-effective choice for flat roofs. However, it may not be as aesthetically pleasing as other options.
  1. PVC roofing: PVC roofing is a single-ply membrane that offers excellent durability and resistance to chemicals, fire, and UV rays. It is also highly reflective, which helps to reduce energy costs. However, PVC roofing can be more expensive than other options.
  1. TPO roofing: TPO roofing is a single-ply membrane that is known for its energy efficiency and durability. It is resistant to UV rays, chemicals, and punctures, making it a popular choice for flat roofs. However, TPO roofing may not be as aesthetically pleasing as some other materials.

Each of these flat roofing materials has its own unique characteristics and suitability for different climates and budgets. Consider your specific needs and consult with a professional to determine the best material for your flat roof replacement project.

Flat roof replacement technology:

  1. The complete dismantling of the damaged roll cover is being carried out. The working surface is cleaned using stiff brushes, shovels, and grinding machines. The removed roofing material is cut into small sheets, which are folded separately. The old roofing must be taken to a specialized landfill after dismantling.
  2. A visual inspection of the working surface is conducted, during which its technical condition is determined. If a concrete screed is damaged, then it must be dismantled. Special breakers are used to remove the concrete layer. After cleaning, the surface is moistened with water.
  3. Linear guides are being installed. When installing, observe the sloped roofs at 3-5% from the center to the roof’s edges.
  4. The concrete screed is poured. For this, the mixture is served in portions, starting from the center of the roof.
  5. After pouring and distribution, the concrete screed is covered with polyethylene. In this state, the roof’s surface must be moistened with water 2-3 times a day for seven days. The total drying time of the concrete layer is 28 days.
  6. Roll or membrane coating is laid after the concrete screed has wholly dried.
  7. After the screed dries, the surface is cleaned of abrasive particles. Next, the vapor barrier diffusion membrane is laid. Vapor insulation is applied with an overlap of 10-15 cm relative to the adjacent row.
  8. A mineral or basalt wool insulation is placed on the concrete screed.
  9. A thin-layer concrete screed is poured. After the second layer of concrete screed dries, begin laying the modified bitumen.
  10. The roofing material is mounted in a run with an overhang on the sides of the roof. If a roll type of material is used, the surface is lubricated with a primer. Then the material is applied.
  11. Roof systems and other accessories are installed at the final stage.

Conclusion about flat roof replacement

In each case, the capital repair of a flat roof may have pros and cons. To a large extent, this is related to the operational condition of the roof. But in general, the capital repair is easy to install and consists of dismantling, cleaning, preparing the old surface, and laying the single-ply roofing materials.
