Leaks that happen around the seams or flashing are often due to ponding water. This happens when water that puddles after a rainfall for more than 48 hours. Other leaks can occur from chimneys, skylights, roof drains and other penetrations. A few leaks in your roof doesn’t always mean it needs replacing. Replacing your roof should really be last resort, as it can be time consuming and costly.
So when should you consider replacing your roof?
There are two ways to determine that. The first is when the original installation has reached its life expectancy. BUR and Modified Bitumen have a life span of 10-20 years and Single PLY can range from 7-10 years for EPDM, TPO and 30+ years for PVC.
The second is when the original roof has not been properly installed, which can result in on going leaks. If the insulation under your roof is wet, it will not be able to dry out on its own. This can lead to structural damage and mold. Fixing this damage can be more expensive than putting a new roof or replacing a section of the old roof.
