Understanding about how the different elements of your roof works can go a long way to staying on top of its condition.  One of the parts to pay attention to is flashing.  Flashing is something that not a lot of people know about, when in fact it is something that is important to the function of your roof.  Flashing is a thin piece of metal or can be another type of waterproof material as long as it is that is meant to prevent water or other build-up from getting into vulnerable areas on the roof. You will find that the flashing is either exposed or concealed on the roof.

Exposed Roof Flashing

Often if the flashing is exposed, it is made from a metal such as lead, copper, aluminum, or other painted, galvanized steel material. Flashing got its name from being exposed to the sunlight, which then shines out and creates a flashing effect. Copper is one of the most used materials for flashing since it is durable and creates no weak spots throughout the roof. Copper also does not wither away from the weather elements.

Concealed Roof Flashing

Usually any flashing that is concealed is made from a waterproof fabric or sheet metal. Sometimes the membrane can even be made of plastic, but this all depends on the area the home is in and the structure itself. Aluminum is not usually recommended when it comes to concealed flashing since it can cause a chemical reaction with the mortar that is used in the home.

Types of Flashing

Flashing is usually used in two different places: around spots on the roof such as bolted areas, skylights, and chimneys to keep the water from pooling in these vulnerable areas; it's also used  to provide a protective barrier around pipes and cables. There are many types, brands, and styles of flashing to choose from, so it's a good idea to talk with a roofing professional about what's appropriate for your home.  Flashing serves an important function, and choosing the right product involves more than aesthetics.   And professional installation is a must.  You do not want to face headaches in the future if the flashing is not installed correctly.
