Building roofs have been simpler than maintaining and a regular inspection to keep the roof functioning for a long and reasonable period. Whether you are a homeowner with a flat roof or have a commercial building with a flat roof you may be aware of the work it requires to be maintained compared to other types of roofs. It is often a challenge to identify whether the roof is in need of a whole replacement or just a few repairs. Following in this reading we have provided you with a list of the common issues that occur in flat roofs and ways to deal with these issues. 

  1. If you see cracks and bubbles that make the asphalt used to build your flat roof look like the skin of an alligator it is called alligatoring. This means your flat roof needs to be replaced. 
  2. One of the most common issues with flat roofs is leaking and moisture. Since the water has nowhere else to go on a flat roof it causes leaking and often the moisture seeps into the roof itself, causing mold and fungus. Regular inspections and maintenance of the roof are the best advised ways to deal with leak and moisture issues in your flat roof. 
  3. Most asphalt flat roofs are made up of a membrane soaked in asphalt and laid across the top of the building. The membrane on the flat roof is all one piece and over time that shits and settles over time. Excessive movement causes buckles in the membrane which not signifies safety risks and the end of the flat roof’s life but is required to be replaced as soon as possible. 
  4. With the settlement of homes over time, the roof will shift too which means it will no longer be as leveled as it was first installed. This causes the water to pool in divots in the roof since it has nowhere else to go due to it being flat. A check is needed to ensure that water has not gone to the lower layers of the roof and that these pools are drained as soon as possible. If the pools are not taken care of it damages the exterior of the roof, as well as shortening the lifetime of the flat roof. 
  5. Flat roofs due to it being flat tends to have more pressure on them. Often this built up pressure can cause cracks in the roof. In the event of seeing a crack in your roof professionals should be called to assess your roof. However; a crack in the roof is often a sign that it is time for a new one. 
  6. Asphalt flat roofs tend to change, expand and contract as weather and temperatures change.  

Over time the continued expansion and changes cause the edges and corners of the roof to be destroyed, which in turn allows leaking and moisture going in to your roof. The best advice to avoid this from happening is regular inspection and maintenance of your roof by a professional before you are left with no other choice but to replace the roof.




To repair a flat roof means to restore functionality to the roof, reinforce the flat roof
waterproofing and insulation properties and prevent overall damage to the roof over time. This
does not mean immediately tearing off all the layers of the flat roof, especially without analysis
of the causes of damage. Some parts of the flat roof can serve as a substrate for the new layers.

The first step to repairing a flat roof is to recognize the state of roof the and identify the cause of
any flat roof leaks. Revealing the space under the flat roof does not always show faulty or
damaged waterproofing. Flat roof leaks can also stem from errors resulting from building physics
or mistakes made ​​in the construction (drains, pipes, etc.) A flat roof can be installed with the
highest quality materials, but if poorly constructed – temperature changes, weather and debris
will lead to corrosion, damaged insulation, ridging, blistering, alligatoring and other common flat
