Roof vent pipe repair in Virginia can be very tricky

Roof Vent Pipe Repair Company in Northern Virginia

If you look at your home’s roof, you’re most likely to see a roof vent pipe protruding through your roof. These vent pipes allow gas to safely exit your home. The gas originates from the toilets and sinks then travels up through the venting pipe, and exits the home where the pipe protrudes through the roof. Every 8 – 10 years they should be inspected for a roof vent pipe repair

Common Roof Vent Pipe Leak Repairs

When trying to pinpoint the source of a roof leak in VA, you’ll need to examine the vent pipe. Occasionally a vent pipe leak can occur at the collar surrounding the base of the vent pipe where it penetrates through the surface of the roofing material. These collars are made with a metal base, generally consisting out of aluminum, and a rubber boot integrated into the top of the collar. The collar’s job is to create a water tight seal, keeping rainwater and debris from getting into your attic. Over time due to the exposure of the sun and harsh weather conditions in Fairfax and surrounding areas of Northern Virginia, the rubber boot may wear out and deteriorate or crack. When this occurs, rainwater can seep in between the rubber boot and the vent pipe causing leakage in your home. If the rubber boot collar is cracked or damaged, it will need to be replaced by one of our professional Roof.net roofers

My New Roof Vent Pipe Flashing is Still Leaking

If the vent pipe flashing was installed correctly then this is when you’ll need the services of Roof.net. There are many other problems that can cause a VA roof vent pipe leak!

During a rainstorm, some rain will fall directly into the open end of the vent pipe. This rainwater makes its way down the vent and ultimately to your home’s sewer line. If there are leaks in the elbows or joints on this line, water can seep out and cause interior damage. If the vent pipe is clogged with debris or leaves it will cause water to back up inside the pipe and leak into the attic. If the pipe is clogged then you can use a snake to unclog it.

Check the entire roof above the roof vent pipe leak for any damaged or cracked shingles. If all looks well then there’s a problem with the roof above the vent pipe which is causing the water to travel between the shingles and the felt paper to the problem roof vent pipe leak.

Here at Roof.net we have over 40 years’ experience to know that water can travel from anywhere above and show no signs of leakage in the attic until it reaches the problem roof vent pipe.

Always keep in mind when water travels between the shingles and felt paper it looks for an opening. In this case it’s the vent pipe because it protrudes through the roof sheathing.  If the vent pipe wasn’t there you wouldn’t know you have a leak. This can can go undetected for years!
