While it can be “out of sight, out of mind” for many homeowners, roof vent and water leaks can be a big source of frustration! They can be a common roofing issue that will lead to significant damage if not addressed promptly. Understanding the causes and solutions for fixing a roof vent leak is essential in maintaining the health and integrity of your home and its roofing system. Read on to learn more or contact our team at RoofPRO today! 

What are Common Causes of Roof Vent Leaks?

From flashing damage to broken materials and seams, there are several things that can cause a roof vent to leak! If you’re unsure of the source of your leak, feel free to reach out to our team at RoofPRO for a free inspection and estimate.  

Flashing Damage

One of the most common causes of roof vent leaks is damage to the surrounding vent flashing. Flashing is the metal strip that surrounds the base of the vent pipe, providing a waterproof barrier where the pipe meets the roof. Over time, flashing can deteriorate due to weather exposure, leading to gaps where water can seep through and cause problems to your interior.

Broken Vent Pipe Collars

Vent pipe collars, also known as vent sleeves, are another critical component that is prone to damage. These collars wrap around the base of vent pipes and, when cracked or broken via storms or other wear and tear, can allow water to enter the home. Routine and professional inspection can help identify these issues before they lead to serious leaks and damage to your home!  

Poorly Sealed Seams Near the Roof Vent

Improperly sealed seams near roof vents are a less obvious but equally problematic cause of leaks! These seams should be securely sealed during installation, but exposure to the elements can weaken the sealant over time, necessitating reapplication or repair. While this can be tough to diagnose initially, it can be one of the easier fixes when it comes to roof vent leaks. 

A Leaking Roof Can Be a Big Problem for Your Home

A leak from your roofing system is more than just a minor inconvenience; it’s a significant concern that can lead to a host of problems within your home and roofing system. Over time, even a small leak can compromise the structural integrity of your house and roof deck, leading to issues like weakened beams and rafters, damaged ceilings, and mold growth!  

Furthermore, water infiltration can ruin insulation, electrical wiring, and even personal belongings. Therefore, it is vital to address any kind of roof or vent leaks promptly to prevent extensive and costly damage. 

Interior Water Damage

As stated previously, a roof vent leak, if left unchecked, can result in significant interior water damage. This damage can manifest as stained ceilings, peeling paint, or warped wood. In severe cases, prolonged exposure to water can weaken structural elements! 

Moisture and Mold Build-Up in Your Attic

Beyond visible water damage, a leaking roof vent can also lead to moisture accumulation in your attic. This damp environment is ideal for mold growth, which can spread and potentially cause health issues for those inside your home, as well as damage to your property’s structure.

Can I Fix a Roof Vent Leak on My Own?

Fixing a roof vent leak on your own is a feasible task for those with basic DIY skills and comfort working at heights. It involves several steps, including assessing the damage, removing old sealant, applying new caulk or sealant, and possibly replacing the vent’s gasket or collar. While the process can be straightforward, it’s crucial to prioritize safety by using a sturdy ladder, wearing appropriate footwear, and considering safety gear like gloves and eyewear!  

However, if the damage is extensive or if you’re unsure about any part of the process, it’s advisable to seek professional help. Roofing experts like RoofPRO have the experience, tools, and knowledge to safely and effectively repair roof vent leaks, ensuring long-term solutions and peace of mind.

NOTE: Use Extreme Caution When Working on a Roof

For those willing to take on these kinds of repairs themselves, it’s vital to make safety a top priority. Working on a roof can be extremely hazardous, especially if the roof is steep or wet. While we advise calling a professional for help, those who take on these projects should always use a stable ladder, wear non-slip shoes, and consider using a safety harness when working on your roofing system.  

1) Scrape Old Caulk/Sealant from the Base of the Vent Pipe

The first step to repairing a roof vent leak is to remove any old caulk or sealant from around the base of the vent pipe. This will allow for a clean surface to apply the new pipe flashing, ensuring a more effective and long-lasting seal. If a new gasket is placed over a pipe with old caulk, it can create small places for water it infiltrate. 

2) Gently Remove All Roofing Material Around Vent

It’s important to remove the shingles and roofing material that is directly around the vent pipe. After this, depending on the condition, you’ll most likely need to install new underlayment such as ice and watershield. You’ll want to remove the old material gently so as not to damage the surrounding roof. 

3) Install the Flashing and Roofing Material

Place the new pipe flashing over the vent along with caulk around the outer edge of the gasket as needed. Install the new shingles or roofing around the new pipe collar and secure it in place. Be sure to secure the roofing material next to the new shingles and caulk any existing fasteners. 

Feel Free to Contact a Professional if Unsure

If you’re unsure about any part of the process or the damage seems too extensive for a DIY repair, it’s wise to contact a professional roofing contractor, like RoofPRO! We have the expertise and equipment to handle the repair safely and effectively, ensuring peace of mind for years to come.
