High quality wall flashings as moisture protection

Roofing in the form of tiles or sheets is by no means enough to ensure the complete waterproofing of a building's roof. In addition, among other things, the installation of so-called wall flashings, or chest flashings, is also required.

The most important facts about wall flashings at a glance

• Wall flashings ensure that no water can enter at transitions between vertical elements such as dormers and the roof.

• Wall flashings, or breast plates, are available in a variety of metals such as aluminum, steel, titanium zinc and copper.

• When choosing a particular material, it's important to consider the metal from which other building components such as gutters or valley flashings are made.

• For wall flashing to be installed properly, it must be the right size as well as the right angle.

What is the function of wall flashing?

In order to prevent rainwater penetration and associated moisture damage to the building, roofs must of course be completely waterproof. While this is easily achieved on the roof slope surfaces with tiles or even sheet metal coverings, the transitions between the roof and the vertical building elements are always a weak point in this respect.

To prevent rainwater penetration into the building, roofs must of course be completely watertight.

To seal these transitions, as they are present in addition to the facade, for example on dormers and chimneys, wall flashings, or breast plates, are attached. The plates there practically represent a connection between the vertical wall and the pitched roof and ensure the drainage of rainwater.

Wall flashings are made of different materials

Wall flashings are made from a variety of metals. Typically, they are made from aluminum, titanium zinc, copper or steel. As long as quality is assured, the materials can all offer decent stability and long life, although there are some differences.

Whatever the case, when making your choice, it is of course wise to opt for chest plates made of the same material as other existing metal structural elements. For example, if a roof has been covered with stainless steel trapezoidal sheets, steel wall flashings are usually used as well.

Steel Wall Flashings

Over time, steel has become an increasingly common material for roof flashings. Stainless steel wall flashings are characterized by a high degree of stability. They are rustproof and weather resistant, so there is no reason why steel breast plates should not have a long service life.

Zinc Titanium Wall Flashings

Zinc titanium is also strong and durable, so this material is ideal for making high quality wall flashings. One of the characteristic properties of titanium zinc is that a gray patina forms on the surface over time.

Aluminum wall flashings

Aluminum is lighter than steel. Therefore, aluminum wall flashings are generally lighter than steel wall flashings of the same size and thickness. Aluminum is non-corrosive and weather resistant. However, it is not as strong as steel. For use as wall flashing, however, this is not a problem, so there is normally no disadvantage to be expected in terms of sheet longevity.

Copper wall flashing

Copper has been used for a very long time as a material for building components such as gutters or roof sheets. This metal is characterized by a long service life and is appreciated, among other things, for the typical green patina that forms after some time. Copper wall flashings are found especially on older buildings, where they blend in perfectly with the overall appearance. In principle, however, there is of course nothing to prevent them from being installed on newer buildings as well.

Wall flashings in different colours

Wall flashings are not only available in different materials. In addition, the chest plates also come in different colors. In addition to plates in the color of the metal concerned, you can choose from a range of colored plates. There is a choice of colors such as anthracite, white, brown or even green and blue.

What to look for when buying wall flashing?

Generally, it is of course also important when buying wall connection plates to pay attention to good quality, in order to guarantee a long life. Apart from that, the chest plate must of course have the right dimensions. This applies not only to the length, but especially to the width as well as the angle of the plate.

Depending on the other metals installed on the roof (e.g. in the form of gutters or flashings), it may also be advisable to limit the choice of material accordingly. This is because some metals do not get along with each other.

It is precisely the combination of copper with other metals, such as steel or titanium zinc, that proves problematic in this regard. Therefore, to avoid excessive corrosion, it is best to use copper wall flashings with other copper roofing sheets.
