When your roof is leaking, you should hire an experienced roofing contractor to assess the situation and provide a lasting solution. Knowing the cause of the leak will help to prevent the problem from getting worse and protect your home. 

How does roof damage develop? What can you do to prevent or address the issues? 

Here’s what to know: 

Water build-up 

You are likely to notice a build-up of water on your roof if the surface has a low slope. This build-up will lead to excessive weight and stress on the roof which could damage the roof, causing it to leak. To protect your roof from this, you should assure the surface is well designed and have a proper draining system with clear gutters, drains and downspouts. 

Improper sealing 

Gas lines, vents, HVAC units and pipes can lead to a leaky roof if they aren’t properly sealed. Without giving these the proper attention during installation, they will become open holes in the roof membrane. A roofing contractor will ensure the penetrations are properly sealed to avoid the problem. Regular roof maintenance and inspection will further prevent leaks and expensive repairs. 

Roof membrane damage

The roof membrane is a waterproof layer that seals the interior of your home, effectively preventing water from leaking. However, factors such as harsh weather, foot traffic, mechanical damage and wear and tear can compromise the structural integrity of the membrane. Regular maintenance, inspections and repairs will ensure it remains in good shape. In severe cases of damage, the roof membrane may need to be replaced. 

Aging Roof

Your roof will become weaker as it ages, even with regular maintenance. Constant exposure to the elements will damage the structure of the roof and increase the chances of leaks. Flat roofs will reach the end of their useful life somewhere between 15 and 20 years. If your leaking roof has served its useful life, it’s best to have it replaced.
