Tips to Ensure Your Roof Flashing Never Leaks
One of the most commonest and recurrent problems homeowners come with is a faulty flashing. A faulty flashing shows signs of water leaking through the chimney or mold ruining the walls and the ceiling of the house. Intriguingly, fixing this solution is pretty straight forward: correct flashing installation. A licensed roofing contractor should be able to install a leak-proof flashing around your chimney so that you never get the chance to complain about it.
What is roof flashing?
Flashing is the metal membrane that is added to the junction of your chimney and roof to provide a proper fixation, cover up cracks and holes, and ultimately stop rainwater from leaking into the interior of your house.
The metal used in flashing can vary according to your location and also on your budget. High-end flashing material includes copper that has a very long life. Copper is also one of the best options in the market currently because it can be used to make a solid watertight connection which greatly reduces the chances of a leak. But because of its high price, the average consumer usually opts for aluminum or galvanized steel instead.
Although the type of metal used in the flashing can affect the quality of your flashing, correct installation still has a bigger role in constructing a leak-proof flashing.
Installing a leak-proof flashing
The installation process consists of multiple steps. Normally, more than one layer of flashing is applied on the roof to really make sure there are no gaps left in the intersection between your roof and the chimney. Your roofing company will move systematically by first applying a step-flashing and then counter-flashing the junction. Step-flashing consists of wrapping an L-shaped metal meet around the shingle course and up towards the side of your chimney.
Counter-flashing comes next and involves a second layer of metal that is fixed on the mortar joints of your chimney. This second layer envelops the first layer of step-flashing.
The corners of the flashing need to be paid special attention to as well. These corners often end up with gaps or holes that promote leaking. To overcome this problem, all crevices and corners should be sealed with urethane caulk. The sealant is an additional step in flashing and should not replace the double layers of metal sheet.
