![]() Steel flashing is the most popular choice for flashing.Copper flashing is routinely found around chimneys. On the other hand, there is some discoloring into patina, which can vary based on the homeowner. Not only that, it is highly durable and tends to have a longer-lasting life. Copper roof flashing takes soldering well and is also malleable.There is one thing to note, however: aluminum has to be coated if it is going to be used with masonry and concrete since plain aluminum degrades and reacts when it makes contact with alkaline surfaces. Aluminum flashing is generally easy for roofers to form and it is also quite lightweight.Now, professionals throughout North America have switched to one of three materials. In the past, this would be lead or materials that were lead-coated. There are also a few different roofing materials that you need to be aware of. This kind of flashing is used to direct water away from the wall and down into the gutter. Roofing contractors generally need something to bridge the gap where the step flashing comes to an end and where the gutter begins. At the edge of the roof, there is a thin metal flashing that allows water to drip off the roof without doing damage to the home or causing a pesky leak that can do further damage to the roof or home. Any open valleys on your roof have metal flashing in order to protect this area, which is a critical area of the roof. Knowing which option you have beforehand is helpful. There are some skylight manufacturers that include flashing with their product, but others will require you to create it or purchase it separately. In this instance, multiple pieces of flashing will be installed as layers with the shingles to make sure that the water flows away from the wall. This is a rectangular piece of flashing that is bent 90 degrees in the middle. Counter flashing completes the team with the aforementioned base flashing. This is placed opposite of base flashing, or above the base flashing. Not only that, it is notoriously difficult to install flashing around a chimney. This is to ensure that the rain always meets a flashing surface to direct it downward. There are some roof features, like chimneys, that require two pieces of flashing. It is a long, single piece of metal that is used to carry the water down to the shingles that lay below. This is also known as “apron flashing” because it acts in a similar manner to an apron. So, what do you do when you find yourself needing roof flashing? Knowing the different types as well as the techniques to implement can be helpful. Without the roof flashing against those walls, water would slowly drip into the space between the roof and wall and even potentially into the home. Water should then run down the side of the flashing and wind up getting directed to the shingles instead of finding a way into the roof deck. The flashing is installed to surround the features of the roof, like chimneys, vents, and skylights.
