The Common Causes Of Roof Leaks


The fact is, a leaking roof is a common problem homeowners face, and there are several reasons it occurs. Some of the reasons include:

• Improper ventilation 
• Poorly maintained or installed roof penetrations 
• Ice dams 
• Poor workmanship 
• Insufficient underlayment 

Improper Ventilation 

Sometimes the water drops you see are not actually from a leaking roof but simply as a result of moisture condensation. This occurs due to improper ventilation system. It is paramount to have proper attic ventilation to maintain optimal function and longevity of your roofing system. What is proper ventilation?

Well, proper ventilation simply refers to a perfect balance between exhaust and intake. It involves closing air leaks and correct bathroom venting, dryer, dishwasher, and washer, with the perfect amount of insulation. By chance, if any of the above elements are installed poorly, it may lead to moisture buildup, which is a leading cause of rotting wood and mold growth. 

Roof Penetrations 

Water leaks commonly occur around where there are roof penetrations or objects that have penetrated the roof. Examples include wall flashings, terminations, dormer walls, plumbing stacks, vent pipes, and even chimneys. The area around the penetrants is the most vulnerable part of the room, and if improperly maintained or installed, it could cause a lot of problems. These areas need a great deal of time and the touch of an expert. 

Ice Dams 

An Ice dam is as a result of constant freezing and thawing processes of ice or snow on the roof. With time, ice will build up at the base of the roof, around the eaves. As such, when the ice melts, it may cause water to seep through into the shingles and eventually into the roof. A professional roofer can help you fix the problem and prevent it from recurring in the future. 

Poor Workmanship 

A roof consists of different components that must work together to have a complete system. For this reason, poor workmanship can lead to a serious problem like a leaking roof. This is one of the reasons to always hire an experienced professional roof contractor that knows what they are doing. 

Insufficient Underlayment 

Underlayment is a layer that is located between a roof deck and shingles. This layer is made up of breathable synthetic material. What many people do not know is that it is an important component. As such, if not installed properly, it puts your roof at a greater risk of leaks, especially during a wind-driven rain. 

What Should You Check For? 

NOTE: By the time you notice leaks coming through the ceiling, it means that your roof has been leaking for a while.

As such, when this happens, you should take a few precautionary measures. You should look for the following signs:

• A visible sagging roof from outside 
• Water stains on the roof rafters, beams, and sheathing 
• Wood stains in the garage 

The moment you see any sign of a leaking roof; you should call a professional immediately.
