Metal Flashing vs Flexible Flashing: Which One’s the Best Way to Go?

At the time of applying flashing to buildings, walls, and structures, it is vital to select the ideal material for these specific circumstances. After all, the flashing will be preventing the passage of water into the structure. Choose the wrong material and you will be dealing with humidity, leaks, and worse. A lot of contractors will tend to suggest flexible flashing materials given their lower cost and easier application. However, others will probably suggest metal flashing in Seattle because of how durable it is. This is not necessarily an easy choice, plus the specific circumstances will ultimately influence the material you should use, but here are a few key pointers that could help the decision. It’s important to assess your options before settling for any material.

Flexible Flashing

The types of flashing that are considered to be flexible implement materials include rubberized asphalt, polyvinylidene fluoride (kylar), acrylic, and butyl rubber. 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. This means that the specific circumstances of the building in question will need to be properly taken into account at the time of flashing. Since most of these materials are adhesive backed, they tend to be quite convenient for installation. However, these are not intended for long-term exposure or water resistance. In fact, none of the flexible flashing materials available are designed to be exposed to elements for nearly as long as metal flashing materials.

Metal Flashing

Metal flashing, on the other hand, is specifically designed to withstand long-term exposure. Materials used in metal flashing include aluminium, lead, copper, stainless steel, and specific alloys. 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. Despite the more complicated installation of the material, it tends to prove itself a better choice overall. 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. At the end of the day, a sturdy and cost-effective material such as aluminium will always be an ideal choice at the time of flashing. That’s true even if at first the choice seems intimidating or complicated.
