Is your roof safe from water damage? 
 

Without proper waterproofing, you could face leaks, cracks, and even ceiling damage. 

To protect your home and extend the life of your roof, applying a waterproof coating to your roof is essential. And to ensure your roof’s quality remain intact along with, it is important to choose the right waterproof coating. 

With several options available, you must have an understanding of what makes each one effective and durable. This guide is here to help you with just that. 
 

Understanding your roof’s needs 
 

To choose the most suitable waterproof coating for your roof, consider the following factors – 

• Roof type and climate  -
  
  The type of roof you have and the climate in your area are fundamental in determining the best waterproof coating. 
  
  For instance, roofs in areas with heavy rainfall or extreme temperature fluctuations require coatings that are highly resistant to water penetration and can expand and contract without cracking. 
  
  On the other hand, roofs in milder climates may not need such heavy-duty solutions. 
   
• Substrate material  -
  
  The material of your roof’s substrate—whether concrete or metal—also plays a significant role in the selection process. Each material has different absorption rates, adhesion properties, and expansion behaviours, all of which should be considered when choosing a waterproof coating. 
   
• Roof size and foot traffic  -
  
  The span of your roof and the level of foot traffic it experiences are critical factors – 
  
  Small to medium roofs (up to 7000 sq. ft.) 
  
  For these roofs, an effective waterproof coating that offers long-lasting protection is generally sufficient. These coatings are designed to handle moderate expansion and contraction, providing reliable waterproofing without the need for extreme thickness. 
  
  Large roofs (more than 7000 sq. ft.)  
  
  Larger roofs require specialised attention due to their increased surface area and susceptibility to environmental stresses. For these roofs, Dr. Fixit recommends coatings with a thickness of 1000 microns or more as they offer enough protection to withstand heavy foot traffic and mechanical stresses. 
   
• High foot traffic areas  -
  
  If your roof is subject to high roof traffic, choose a waterproof coating that enhances tensile strength and durability. Coatings that incorporate fibre mesh reinforcement are particularly effective in these scenarios. The added reinforcement increases the roof’s ability to resist wear and tear, ensuring that the waterproofing remains intact even under constant use.  
   
  
   
   

  Evaluating performance characteristics 

When selecting a waterproof coating for your roof, consider the following performance factors – 
 

• Durability – Ensure the coating can withstand the elements over time, maintaining its protective qualities even under harsh conditions. 
   
• UV resistance – UV rays can degrade roofing materials, so choosing a coating with high UV resistance will extend the life of your roof. 
   
• Flexibility – A good waterproof coating should be flexible enough to accommodate the natural movements on your roof without leaking, cracking or peeling.
