Growing up in a house full of girls, I unofficially took on the role as my father's only son. So when the time came to fix a leaky sink or change the oil in the family car, it was me that stood by my father's side. Thanks to him and everything he taught me, I am now able to take care of myself and my children in a way that not everyone can. I have tried over the years to engage my own daughter in the same way my father engaged me, but she's currently more interested in playing with dolls than fixing potholes. After my father passed away last year, I vowed to find a way to pass on everything he taught me, this blog is my way of keeping that promise. I truly hope that you learn as much as I have over the years.
The best way to stop leaks from forming around protruding items on your roof, such as chimneys and vents, is with flashing. Since there are so many materials to pick from, it can be difficult to select a flashing material for your roof. By understanding the pros and cons of two popular types of flashing materials, you can decide on which one is best for your roof.
Many homeowners decide to go with copper because it's very durable, but also pliable. Copper can be customized to fit around the most complicated roofing configurations, making it an ideal choice for most roofs. When copper needs to be joined together, it can easily be soldered. Soldering is an ideal way to connect two sections of flashing together because it makes the material watertight. Other materials that use chemical or mechanical fasteners run the risk of leaking or breaking down much faster.
Copper's biggest disadvantage is that the material is pricy. The material also requires some skill to install, which may result in needing to have a professional perform the installation for you. These two factors combined will make the material expensive to use. Copper also runs the risk of causing stains to form on your roof when rainwater runs over it, which will require a drop edge or overhang to fix.
When compared to copper, aluminum is a much cheaper material. The installation costs will also be lower because you have the option of purchasing aluminum flashing preformed. While aluminum flashing can be installed in an unfinished state, the material can be painted. This gives you a great way to improve on the aesthetics of your home by painting the flashing a color that matches your existing roof. Painting the flashing also provides a layer of protection from corrosion.
Corrosion is aluminum's biggest weakness, which is caused by the alkaline content found in cement, mortar, and concrete that is commonly used in masonry work for a chimney. You will be unable to solder aluminum, making it more susceptible to problems. An adhesive must be used, like caulk, which is not as watertight as soldering. The adhesive will also be an additional cost you must factor into your budget.
Now that you know the differences between copper and aluminum flashing, you can make an informed decision about which material is right for your home. If you have more questions, contact a local roofing contractor that can help.
