The right setup of counter flashing is crucial to prevent leaks, protect your property structure, and keep the overall integrity of your roof.
Counter Flashing Types
Counter flashing broadly speaking refers back to the steel piece that overlaps step flashing, there can be variations in its shape and setup depending on the roof’s particular conditions. There are several types of counter flashing used, depending on the specific needs of the building and the design of the roof. Here are the main types:
1. Standard Counter Flashing:
That is the most common type, a flat metallic piece bent at a ninety-degree perspective to overlap the step flashing.
2. Custom Counter Flashing:
For complex roof structures or unique architectural patterns, custom counter flashing might be to fit the specific contours of the roof and wall intersection.

Measure the area where the counter flashing might be installed and reduce the metal to size.
3. Overlapping:
Use the counter flashing to overlap the step flashing through several inches.
4. Securing:
Fasten the counter flashing to the wall or chimney using appropriate fasteners like nails or screws.
5. Sealant:
Fix a sealant around the edges and joints to create a watertight seal.
How to Repair Counter Flashing?

4. Set up:
Use a brand new piece of counter flashing, overlapping the present flashing and securing it properly.
5. Sealant:
Apply sealant to make certain a watertight seal.
Different Methods to Install Counter Flashing
While there’s no significant variation in the basic principle of overlapping the step flashing, the installation method can differ based on the roof’s material and complexity.
1. Wall set up:
This entails securing the counter flashing to the wall cavity, which is then fixed at outdoor siding or masonry.
2. Floor mount installation:
The counter flashing is connected to the outside surface of the roof or wall using fasteners and sealant.
3. Reglet setup:
This technique entails the usage of a pre-fabricated metal channel (reglet) to create a base for the counter flashing, ensuring a smooth or even setup.

FAQ’s
What is counter flashing?
Counter flashing on a roof is a metallic piece hooked up over step flashing to create a double layer of safety. It overlaps the step flashing, forming a watertight seal between the roof and wall, preventing leaks.
What is counter flashing on a chimney?
Counter flashing on a chimney is a steel barrier installed over the base flashing. It creates a double layer of safety, stopping water from getting into the gap between the chimney and roof, and safeguarding your home from leaks.
Is counter flashing necessary?
Yes, counter flashing is necessary for a strong roof. It provides a second layer of protection against water infiltration at the critical junction where the roof meets a vertical surface. Without it, water can seep into your home, causing significant damage.
How tall should counter flashing be?
The ideal height for counter flashing is typically 4 inches. This allows for sufficient overlap with the step flashing and ensures proper water drainage. However, the exact height might vary slightly depending on the specific roof and wall conditions.
What is the difference between countertop height and table height?
Countertop height typically ranges from 34 to 36 inches tall and is designed for tasks such as food preparation and school work. Table height, on the other hand, is usually around 28 to 30 inches tall and is designed for comfortable seated dining.
