Metal Flashing: Fold or Solder?
"Fold or Solder: Choosing the Right Method for Your Metal Flashing"
When it comes to installing metal flashing on a roof, you have two main options: folding or soldering. But how do you know which method is best for your project? Here are a few things to consider when deciding between folding and soldering metal flashing:
Thermal movement: One of the key factors to consider is thermal movement, which refers to the expansion and contraction of materials as they are heated and cooled. Metal is especially prone to thermal movement, and it's important to allow for this when installing flashing. Folding creates a hinge-like joint that allows for movement, while soldering creates a permanent bond that may be more prone to stress and failure.
Watertightness: Both folding and soldering can create a watertight seal, but the method you choose may depend on the specific requirements of your project. For example, if you need a very strong and permanent bond, soldering may be the better option. However, if you need a more flexible joint that can accommodate thermal movement, folding may be the better choice.
Durability: In general, folding is a more durable method of joining metal flashing because it allows for movement. This can help to prevent stress and prolong the lifespan of the flashing. Soldering may be more prone to failure due to the brittle nature of the bond it creates.
Cost: Another factor to consider is cost. Soldering generally requires more specialized equipment and may take longer to complete, which can increase the overall cost of the project. Folding is generally faster and may be more cost-effective in some cases.
Ultimately, the decision between folding and soldering metal flashing will depend on your specific needs and the requirements of your project. By considering factors such as thermal movement, watertightness, durability, and cost, you can choose the best method for your roof.
