Two Things To Know About Roof Flashing Material


You may think of roof flashing as a material primarily designed to provide protection from leaks. However, it is also a material that can be used to accentuate a roof due to how visible the material is from the ground. That's why it's important to know the following things about flashing material if the time comes to replace it. 

Are There Different Types Of Flashing?

There are a couple of different types of flashing that are used on a roof, with step flashing being one that many people are familiar with. Step flashing is used in places where a roof runs up against a wall on a downward angle and water needs to be diverted away from the edge of the shingles, which is where water would normally be able to enter. It is placed along the edge of the roofing material, with the flashing going slightly underneath the shingles and slightly up the wall.

Apron flashing is another type of flashing that is similar to step flashing, but it is used at the base of a chimney or dormer. It's placed on the surface where the roof and the structure meet and faces a downward angle. For example, if you had a dormer with a window facing the front of the house, the apron flashing is placed beneath the window where the dormer and roof meet. 

Counter flashing is used when flashing material goes up against brick or stone mortar joints. The flashing material needs to be slightly recessed into the brick or stone so that water cannot get behind the flashing material, since brick or stone can create an uneven surface to place flashing against. 

What Are The Materials Used For Flashing? 

Aluminum is the most basic and affordable material used for roof flashing. It doesn't offer any real benefits other than its low price and is good for regions that don't see much rain during the year. The next step up in flashing material is pre-finished steel. It's a much stronger material than aluminum, which helps it last a long time in comparison. 

Copper is a premium material used for flashing, which is mainly because of the look it provides. It's the most durable flashing material and is used in situations where you have a roofing material that will last a long time. For example, if you have a slate roof, it makes sense to use copper due to the longevity of both materials. Aluminum flashing would likely fail before the slate shingle material.
