What Is Aluminum Flashing, What Does It Do, and Where Is It Installed?
Aluminum flashing is a protective metal material used to prevent water intrusion in exterior walls and siding systems. It seals joints, redirects rainwater, andprotects vulnerable areas from leaks and moisture damage.
These flashings are made of aluminum and are custom-bent using a metal brake machine to fit eachspecific area of the building. One of the most common types is Z-flashing, typically fabricated from aluminum trim coil.
In Chicago homes and buildings, aluminum flashing is commonly installed around siding, windows, doors, dormers, roof edges, and gable walls. Proper aluminum flashing installation and aluminum flashing repair in Chicago help prevent leaks, wood rot, and costly structural damage while extending the life of the siding and exterior wall system.
Flashing Helps Prevent Water Leaks and Keeps Animals Out of the Home
Essentially, flashing helps prevent water leaks by directing rainwater away from vulnerable areas such as siding joints, roof edges, and dormers. Additionally, properly installed flashing seals small openings, helping keep birds, squirrels, and other animals from entering wall cavities.
Where Are Water Leaks and Animal Entry Most Common Around a Home?
Some of the most common areas where water leaks and animals enter homes are dormers, soffit and fascia boards, gable walls, and around windows. These areas depend on properly installed aluminum flashing to keep the structure sealed and protected.
At Pro Siding Chicago Inc, we frequently repair openings and damage around dormers and soffit and fascia areas, which are very vulnerable if flashing is missing or improperly installed. Without proper aluminum flashing installation, birds, squirrels, and other animals can easily enter and build nests inside the roof or wall cavities.
Dormers are especially sensitive because the dormer wall connects directly to the roof. Missing or poorly installed dormer flashing can allow water to penetrate behind the siding and cause interior leaks.
Another common problem area is the gable wall where siding meets brick. If the wall flashing or aluminum flashing is missing or incorrectly installed, water intrusion can occur and animals may find easy access points.
We also see leaks caused by missing or damaged Z-flashing above windows, which allows rainwater to enter behind the siding and eventually leak inside the home.
Proper aluminum flashing repair and replacement in Chicago helps seal these vulnerable areas, preventing water damage, structural problems, and unwanted animal entry.
