Introduction
In the realm of roofing, particularly for shingle roofs, one of the most critical components often overlooked is flashing and counter-flashing. These installations are vital for directing water away from vulnerable areas, ensuring that your roofing system remains intact against leaks and water damage. An understanding of flashing and counter-flashing can empower homeowners when making decisions regarding roof installation, maintenance, or repairs. With the right knowledge and professional assistance from a local roofing company, you can protect your investment effectively.
Understanding the Basics of Roofing
What is Flashing?
Flashing refers to thin pieces of impervious material installed to prevent water from infiltrating areas around roof features such as chimneys, vents, skylights, and valleys. It's commonly made from metals like aluminum or galvanized steel and is essential for any roofing system's integrity.
What is Counter-Flashing?
Counter-flashing complements traditional flashing by providing an additional layer of protection. It is typically installed over existing flashing to seal the joint between the two surfaces. Counter-flashing ensures water runs off your roof instead of penetrating beneath layers where it can cause significant damage.
