Should You Get Flexible or Metal Flashing in Seattle?

At the time of making sure that buildings are properly protected against the elements, you will always need to address the need for flashing. Understanding the importance of choosing good flashing materials in construction will be important in order to ensure the longevity of the building. We work hard to develop proper metal flashing in Seattle regardless of the intended use. However, a lot of people tend to seek out flexible flashing due to its ease of use and installation. Which option will ultimately be better? Let’s see.

Flashing Durability

When it comes to durability, there really is no contest. Flexible flashing, which usually consists of materials such as rubberized asphalt, polyvinylidene fluoride (kylar), acrylic, and butyl rubber, is definitely durable. However, it’s important not to generalize when it comes to just how durable the flashing can be. The application temperature, material adhesion compatibility, material adhesion, levels of volatile organic compounds, chemical compatibility, and resistance to ultraviolet light exposure of each different material will vary from one to the other. The specific choices made will ultimately depend on the conditions of the building in question. Some will definitely be quite durable, but others are not exactly considered the best options. Metal flashing, on the other hand, is specifically designed to withstand long-term exposure. 


Materials used in metal flashing include aluminum, lead, copper, stainless steel, and specific alloys. As you can probably tell already, these are very consistent and reliable materials. Due to the resistance, durability, strength, and endurance of the materials used, metal flashing is commonly thought of as the ideal choice for effective protection. After all, the consistency of metal flashing materials is consistent under the ideal circumstances. One factor in favor of flexible flashing is its ability to withstand temperature changes without disfigurement. However, in order to protect metal flashing from the expansion and contraction commonly caused by temperature changes, it incorporates expansion joints on long runs, preventing deformation. This combines ideal protection with the necessary consistency to withstand strenuous circumstances.


Most of the materials often used for flexible flashing are adhesive-backed. This means that they tend to be quite convenient at the time of installation. However, these are not intended for long-term exposure or water resistance. In fact, as previously stated, none of the flexible flashing materials available are designed to be exposed to elements for nearly as long as metal flashing materials. In other words, they are much more convenient than they are genuinely sturdy. You don’t exactly want to go with the easy option when you are talking about protecting your home from the elements. At the end of the day, equally sturdy and cost-effective materials such as aluminum will always be an ideal choice at the time of flashing.
