What is Roofing Flashing?


Understanding what is flashing in roofing systems

To get into roof flashing definition, take a look at your roof. It doesn’t matter what this part of your home is made of: clay tiles, shingles, wood shakes, metal panels, coal tar pitch, or others. Considering the roofing system, it is just a part of it, but not the main weather barrier that protects your house from water leaking. The inconspicuous hero here is roof flashing. To keep your shingles, some areas of the roof that may be more delicate to damage, and wall constructions from water penetration, you need flashing — a waterproof material that prevents moisture seeping in. So, the process of roof flashing is a way for improving your house and insure yourself from unpleasant consequences, for example, mold. The concept of its work is simple. It collects unnecessary water and directs it away.

Now you know what is flashing in roofing system, but which material is better to choose for this element? There are four common materials:

  • aluminum;
  • galvanized steel;
  • lead;
  • copper.

For house owners who wish to install this part of the roof on their own, the best option will be aluminum. It is the least expensive and durable. However, be careful with aluminum, as flashing pieces can be applied using concrete or cement, so aluminum requires adding a finish to avoid corrosion. Also, galvanized steel will be the most optimal and reliable option. Long exposure to water and moisture is not a challenge to this type of flashing material.
