Understanding Roofing Systems
What is a Roofing System?
A roofing system comprises various components working together to protect your home. These include:

What is Flashing?
Definition of Flashing in Roofing
Flashing refers to thin materials installed at joints, seams, and roof penetrations to divert water away from vulnerable areas. Common materials include metal (like aluminum or copper) or flexible membranes.
Types of Flashing
Step Flashing: Used where a vertical wall meets a sloping roof. Continuous Flashing: Installed along longer joints to provide an added layer of protection. Vent Pipe Flashing: Surrounds pipes that penetrate the roof. Chimney Flashing: Secures the intersection between a chimney and the roof surface.What is Counter-Flashing?
Definition of Counter-Flashing in Roofing
Counter-flashing is an additional layer placed over existing flashing to further protect against water penetration. It acts as a barrier against water that may seep under the primary flashing.
Importance of Counter-Flashing
Counter-flashing plays a crucial role in ensuring long-term leak prevention by covering exposed edges and providing an extra defense layer against wind-driven rain.
How Flashing and Counter-Flashing Protects Your Roof from Leaks
When properly installed, flashing and counter-flashing work together seamlessly to create a watertight seal around critical areas on your roofing system. They guide water away from joints, preventing pooling or penetration that could lead to leaks.
