What are the three flashing methods used on chimneys?

There are three primary methods used to flash a chimney: the step flashing method, the pan flashing method, and the cricket flashing method. Each of these methods has its own set of benefits and drawbacks, so it is important to choose the right one for your needs. 

The step flashing method is the most common type of chimney flashing. It involves attaching a series of L-shaped metal pieces to the base of the chimney, with each piece overlapping the one below it. This overlap creates a water-resistant barrier that prevents water from seeping in around the chimney. The main drawback of this method is that it can be time-consuming and difficult to install. 

The pan flashing method is another popular option for chimney flashing. This method involves installing a metal pan around the base of the chimney. The pan helps to deflect water away from the chimney and prevents it from seeping in. The main drawback of this method is that it can be expensive, as you will need to purchase a custom-made pan. 

The cricket flashing method is a less common but more effective way to flash a chimney. This method involves installing metal strips that run the entire length of the chimney. The strips are spaced about 1 inch apart, and they are arranged in a criss-cross pattern. This pattern helps to deflect water away from the chimney and prevents it from seeping in. The main drawback of this method is that it can be difficult to install, as you will need to use a special flashing tool.
