The answer to 'average cost of flashing' is that the cost can vary significantly depending on several factors. Flashing is a crucial component in roofing systems, used to seal and waterproof areas around chimneys, vents, and other roof penetrations. The cost of flashing can be influenced by the material used (such as aluminum, copper, or stainless steel), the complexity of the installation, and the size and scope of the project.
Typically, homeowners can expect to pay anywhere from a few hundred dollars to several thousand dollars for flashing, depending on the size of the roof and the number of penetrations that need to be sealed. Additionally, the location and accessibility of the roof can also impact the overall cost.
