Through-Wall Flashing protects this gable in all areas vulnerable to potential water leaks. Note that masonry is set within the copper trough, providing an outlet for water to escape--outside the structure, which keeps the inside dry.

Chimney flashing requires careful planning to prevent wet weather leaks. Notice details below as flashing is prepared to protect the chimney. Through-Wall Flashing gives water a safe way to exit a building. The copper "cricket" behind the chimney uses a steep angle to prevent leaves and debris from collecting, to avoid structural deterioration over time.

When executed well, Through-Wall Flashing is barely noticeable, as seen below left. But as the second picture below displays, the outer stone wall can sit within a water-tight trough which will lead water down and away from a building's internal structure.

Copper flashing beneath the wood siding shown below is connected to a wide copper flashing which provides a maintenance walkway, protecting the adjacent slate roof. Water coming off this roof flows into the downspout opening shown on right.
