Roof flashing is an essential part of any roofing system. It provides critical protection against water intrusion, safeguarding your home from leaks and the costly damage they can cause. At Falcon Roofing, we understand how important proper roof flashing installation is, and in this article, we'll explain the process and why it's crucial for the longevity of your roof. Whether you're a homeowner or a professional contractor, this guide will help you understand the ins and outs of flashing installation and how Falcon Roofing can assist you.

What is Roof Flashing?

Roof flashing is a thin material—usually made from metal like aluminum, copper, or galvanized steel—that directs water away from certain vulnerable areas of a roof, such as valleys, chimneys, vents, skylights, and the intersections between different roof sections. It forms a water-resistant barrier that helps prevent moisture from seeping into these areas, which are more susceptible to leaks due to their complex shapes and connections.

Without flashing, even the best roofing materials can struggle to hold up against rain, snow, and ice. Flashing ensures that water is guided safely to the roof's drainage system, minimizing the risk of water damage.

Types of Roof Flashing

At Falcon Roofing, we install several different types of roof flashing, each designed to protect specific areas of the roof. Below are some common types:

1. Step Flashing

This type of flashing is used where the roof meets a vertical wall, such as the side of a dormer or chimney. Step flashing consists of multiple pieces of metal that overlap each other in a "stepped" manner. Each piece is integrated into the shingle system to ensure water is directed away from the wall and onto the roof surface.

2. Continuous Flashing

Also known as "apron flashing," continuous flashing is a long, single piece of metal that protects the area where a sloped roof meets a vertical wall. Because it is a single piece, it allows water to flow smoothly away from the joint.

3. Valley Flashing

Valleys are areas where two roof planes meet, forming a V-shape. Valley flashing is installed to channel water off the roof and into the gutters. Because valleys can collect large amounts of water, proper flashing in these areas is essential to avoid leaks.

4. Drip Edge Flashing

Drip edge flashing is installed along the edges of the roof. It directs water away from the fascia and into the gutter, preventing water from seeping behind the shingles and causing rot.

5. Counter Flashing

This is installed over step flashing or other types of flashing. It's typically used around chimneys or walls to add an extra layer of protection by covering the exposed edges of the primary flashing.

6. Skylight and Vent Flashing

Skylights, vents, and pipes penetrate the roof and create potential entry points for water. Flashing around these elements is critical to ensure they are properly sealed and do not allow moisture to infiltrate the roof.

Importance of Proper Roof Flashing Installation

Improperly installed roof flashing can lead to a host of problems, from small leaks to extensive water damage. At Falcon Roofing, we've seen firsthand the damage caused by poor flashing installation, and we know that taking the time to install flashing correctly is vital for the longevity of your roof.

Here are a few reasons why proper flashing installation is critical:

1. Prevents Water Damage

The primary purpose of flashing is to keep water out of vulnerable areas of your roof. Improper installation can lead to water seeping into these areas, which can cause leaks and eventually rot, mold, or even structural damage to your home.

2. Protects Roof and Wall Materials

Flashing also helps protect roofing materials and the materials that make up your home's walls. Without it, water can damage not just the roof, but the underlying structure, including insulation and drywall.

3. Increases Roof Longevity

A roof with well-installed flashing will last longer because it is better equipped to handle the elements. By keeping water away from weak points in the roof, flashing ensures that the roofing materials remain intact and functional for many years.

4. Energy Efficiency

Leaks in the roof caused by poor flashing can also affect your home's energy efficiency. Moisture can seep into insulation, reducing its effectiveness and causing your HVAC system to work harder to maintain indoor comfort, leading to higher energy bills.

5. Protects Your Investment

Your roof is one of the biggest investments you'll make in your home. Installing flashing correctly protects that investment by ensuring your roof lasts as long as possible with minimal issues.

How to Install Roof Flashing

Roof flashing installation is a technical process that requires careful attention to detail. At Falcon Roofing, we follow a meticulous approach to ensure every piece of flashing is installed perfectly. Here's an overview of the basic steps involved in flashing installation:

1. Preparation

Before installing flashing, the roof area must be cleaned and prepared. Any old flashing, debris, or damaged roofing material is removed, and the surface is made smooth and ready for new flashing.

2. Cutting and Shaping the Flashing

Flashing materials come in various sizes and shapes, but often they need to be cut and bent to fit specific areas of the roof. For example, step flashing pieces are typically bent at a 90-degree angle to fit against the wall and the roof.

3. Installing the Flashing

Once the flashing is cut and shaped, it's installed in layers. For step flashing, each piece is placed between shingles, and the installation follows the slope of the roof. For valley flashing, a continuous strip of metal is installed in the roof valley, and shingles are placed over the edges to direct water into the valley.

4. Securing the Flashing

Flashing is typically nailed or screwed into place, but care must be taken to ensure the fasteners are not overdriven or placed in areas that could lead to water intrusion. Sealants may also be used to ensure a watertight installation, particularly around skylights, chimneys, and other penetrations.

5. Inspecting the Installation

After installation, it's important to inspect the flashing to ensure it is securely fastened, properly sealed, and functioning as intended. At Falcon Roofing, our technicians thoroughly inspect all flashing to guarantee that it will provide long-lasting protection.
