What are 3 Common Roofing Problems You Should Consider?

1. Shrinkage - Pulling at the flashings is a clear indication of shrinkage after installation. This is normally due to the membrane not being cured properly. You may also notice the membrane pulling away from edges which is another sign of shrinkage.
2. Water Pooling  -A roof that has been poorly installed can cause pools of water forming instead of it running or draining off the roof efficiently. This can also result from repairs that were made on the roof not being implemented correctly. The pooling water can occur between the membrane and tiles, on the roof tiles or covering or even under the membrane which can result in leaks occurring.

Even with flat roofs, a slight gradient or drainage system is needed in order to effectively allow water to run away and prevent pooling. Water puddles or pools on the roof can have negative consequences for the roof as well as the structure.
3. Blistering - Blistering is another common problem that occurs with roofing and there are some myths and misconceptions regarding this problem. The problem does not occur because of exposure to the sun but rather because bitumen was not heated to the proper temperature during installation. While it is not always worth the cost of fixing blisters, it can result in the roof deteriorating and ageing much faster.
