Get Rid Of Your Roof Vent Pipe Leaks Once And For All

Getting rid of the leaks around your roof vent pipes does not mean getting rid of the vent pipes altogether. When you are frustrated because you keep getting those nasty water stains in your ceiling and you know there is considerable damage being done to the structure of your home before you even see the stains, you may be inclined to rip your vent pipes out forever.

Don’t be quite so hasty! Those pipes are there for a reason – not just as an anchor point for your roof top holiday display! Anywhere wastewater is produced in your home at plumbing fixtures such as sinks, toilets and showers a vent pipe is needed. The waste eventually ends up in the sewer system connected to your house, but the gases produced needs a place to go and that is precisely the function of your roof vent pipes. Without the pipes you would be inundated with foul odors inside your home.

To locate the leak, you need to climb up into your attic and locate the PVC pipe that goes through your roof. Be careful not to step between the ceiling joists or you may fall through the ceiling. You will have to pull the insulation carefully away from the pipe where it penetrates the roof. If you see daylight you know you have a problem. That’s where water can come through. If the roof decking is rotted, you will need to have it replaced. Hopefully you can locate the problem before it gets that bad. If you think it’s going to rain again before your roofing repair contractor gets to you, tie a towel around the vent pipe to soak up the water before it reaches your ceiling. Most good contractors can be there on the same day you call. One of the most common issues is a cracked boot around your vent pipe. The boot is the rubber cover that hugs the pipe and keeps it watertight. Exposure to the elements causes it to shrink and crack over time. Replacing it is a standard procedure.

 

You could also have the rubber boot replaced with other flashing solutions such as lead pipe flashing that are not nearly as susceptible to the weather as rubber. Your roofing contractor can advise you on the latest technology in repairing roof vent pipe leaks. The important point is to have it handled before it becomes more costly.

How to fix a vent pipe in a building

Vent pipes are used to air the plumbing systems in a building. They are connected to foul and soil water pipes. These are placed on bathroom and lavatory rooms. They allow the foul smell from the utilities to leave the house into the open above the roof. They have caps to prevent birds or pests from entering the house drainage system. They are usually PVC pipes. The pipes can be positioned inside or outside the building. For aesthetic purposes, they are placed inside to give the facades a good appearance.

The diameter of a vent pipes should be a minimum two inches. An air pipe located in the house should be encased in plaster. It should not pass through a living room, bedroom, dinning or kitchen. The connection should start from the ground floor to the roof. It should be from a man hole or inspection chamber to the roof. The connections must be air tight for the system to be effective. All soil or foul water pipes should have good gradients. This is important for the water to clean the pipe as it carries the waste to the sewer.

The fixing of a vent pipe should be done with medium duty pipes. When fixing the air pipe, identify the corner to position it. The water closet is usually a good point of adding the air pipe. The pipe taking the waste to the sewer outside is given a tee junction. The middle point will go into the water pan. The other two ends will connect to the sewer and bend for the air pipe at the corner. The bend connection is done with an appropriate adhesive. The pipe is measured to pass the roof covers. It extends by one foot above the roof while fitted with a cap.

A chicken mesh or gauze wire is tied to the vent pipe. Plaster is done to cover the pipe. Tiling is then done to match the lavatory finish. The point where the pipe cuts through the roof is then sealed. This will prevent rain water from passing into the house. The sealant used should allow for the structure movement. A Hard or brittle sealant will easily get broken and let in water through the crack. Water is then filled to test the system. This should be able to flash without any leakages.
