The answer to how much flashing costs in your area can vary significantly based on several factors. Flashing is a critical roofing component that helps prevent water leaks, and its cost is influenced by the type of material, the size and complexity of your roof, and your local market conditions.
In general, you can expect flashing to cost anywhere from $100 to $500 or more per 100 linear feet, depending on the specific needs of your project. Metal flashing, such as aluminum or galvanized steel, tends to be on the lower end of that range, while specialty materials like copper or stainless steel can be on the higher end. The labor costs to install the flashing can also add significantly to the overall price.
