Roof flashing is an important part of any roofing system. It helps to direct water away from critical areas of the roof and prevents water from seeping into the home.

How do I know if my chimney flashing is leaking

Why does my chimney leak when it rains?
One of the most common reasons for rain to leak into a chimney is physical damage or wear and tear to the chimney. The portion of your chimney that extends outside of your home faces near constant exposure to the elements, including rain, snow, high wind, and sun exposure. Over time, these elements can break down the materials of your chimney, causing cracks and gaps that allow rain to leak in.
Chimney flashing deterioration is a common problem that can occur over time. Metal flashing can rust or otherwise weaken from the elements, and caulking around the flashing can become loose, which can cause problems for the homeowner. Getting up on the roof to inspect the chimney can be dangerous, so it’s important to be aware of these potential problems.
Does flashing need to be caulked
Sealing the flashing is important to prevent water from getting into the cracks and causing damage. Choose a sealant that is compatible with the material of the flashing and apply it according to the manufacturer’s instructions.
This is a very common defect that can occur on new construction projects. Make sure to check the space between the siding and the flashing above any windows to ensure that there is no caulking present.
