Roof vents are a vital part of the roof. Depending on their purpose, they may allow you to reduce condensation in your loft or attic, or allow toxic or unpleasant gases to escape from your house if it is a soil vent or gas vent. However, since they are also an aperture in the roof, they can also be vulnerable to springing a leak. If you’re comfortable working on a roof, then you may be able to sort it out yourself before the leak can do any more damage. This article explains about how to fix a roof vent leak.
How to fix a Roof Vent Leak – Roof Tile Vents and Abutment Vents
Roof Tile Vents and Abutment Vents if properly installed, should not be weak points in a roof’s protection. Roof Tile Vents are too durable, while Abutment vents are cunningly dressed with lead to prevent leaks. However, if improperly installed they may act as areas which can leak. Sometimes a roof vent can simply be removed and installed once more – properly this time. However, if parts of it are missing, or if it is a bad fit for the tiles or roof, it will be worth it ordering another roof vent to fix it. Companies like Klober and Hambleside Danelaw have wide selections of roof tile vents to fit almost any roof line, while Manthorpe produces a top quality abutment vent.
How to fix a Roof Vent Leak – Soil Vents
Soil Vents are pipes that allow the gases in your u-bend to equalise, preventing your toilet from backing up and flooding your house or releasing noxious gases into it. These usually have to penetrate the roof itself and rise a certain height above it. The vent is made of three parts. There’s the pipe itself, the rubber “boot” surrounding it, and the lead flashing that the boot is set into.
This multi-part structure makes soil vents relatively vulnerable to damage. Serious damage to any of the three parts of the soil vent will allow water to enter your roof. You can remove the tiles surrounding the vent to give you access to the vent. Once you have removed the vent as well, you can identify which part is damaged, you can replace it and reinstall the vent, then replace the tiles.
When it comes to reinstalling your soil vent, the ALM Flexi Slate provides a fantastic replacement solution. The rubber-metal joint is nearly seamless and the neoprene boot is tough as they come. The Flexi Slate is also available both in pitched and flat variations.
How to fix a Roof Vent Leak – Gas Vents
If you suspect that a gas vent is the cause of your roofing issue, make sure to call professionals. Fixing a gas vent should not be considered a DIY task. Gas vents are the vents which take away and disperse harmful carbon monoxide gases from appliances. If a gas vent is incorrectly repaired it could block the vent and cause your house to fill with deadly gas. Even approaching the vent could be dangerous. To help monitor harmful carbon monoxide levels, we recommend installing a carbon monoxide detector in your home.
