Picture this: you’ve just installed a beautiful new roof on your home. The shingles are sleek, the color is perfect, and your house looks top-notch. But wait—what about those little metal strips that run along the roof’s edges and around chimneys, vents, and skylights?

Roof flashing may not get as much attention as your shingles or tiles, but let me tell you—it plays a pivotal role in protecting your roof from water damage and ensuring its long-term durability. If you think flashing is just a minor detail, think again! An adequately installed flashing system could be the difference between a dry home and a costly, time-consuming leak repair.

In this post, we’re diving deep into what roof flashing is, why it’s so important, and how it impacts the performance of your roof. We’ll also break down the types of flashing materials, common problems with flashing, and how to spot issues before they cause significant damage.

So, let’s flash forward to this crucial aspect of roofing and learn how it keeps your home safe, dry, and dry for years to come.

What Is Roof Flashing?

Roof flashing is a thin material—typically metal or, in rare cases, hard plastic—installed around roof openings and seams to direct water away from vulnerable areas. It’s like the unsung hero of your roof, essential for maintaining the overall importance of roof protection. While the shingles and tiles may be the show’s star, flashing ensures that water doesn’t slip in where it’s not supposed to.

Essentially, flashing is used to seal joints and seams between roofing materials and other components of your home, such as chimneys, vents, skylights, and valleys. Flashing’s primary purpose is to prevent water penetration and keep your home’s interior safe from leaks, mold, and structural damage.

Imagine a row of bricks in a wall—flashing acts as a protective barrier between the bricks and the water that could seep through if left unchecked. Flashing helps ensure that your roof holds up against the elements by channeling water away from these critical areas.

Why Flashing Is Crucial for Roof Performance

Water is the enemy of any roof. Over time, rain, snow, and ice can compromise your roof’s integrity, especially in areas where roofing materials meet or where penetrations (such as vents, pipe jacks, or chimneys) pierce through the roof. This is where flashing steps in to prevent moisture from creeping in.

The flashing system is your roof’s first line of defense against water damage. Flashing can extend your roof’s lifespan and prevent costly repairs if installed and maintained correctly. Water can infiltrate your home without blinking through seams, joints, and penetrations, leading to leaks and water damage. The worst part? Roof leaks can be sneaky—what looks like a minor issue on the surface can often be masking more significant problems hidden underneath, affecting the integrity of your roof.

Types of Flashing Materials and When They’re Used

Flashing comes in different materials, each suited for different roof types, weather conditions, and installation areas. Let’s go over the most common flashing materials and where they are typically used:

1. Aluminum Flashing (what is used 95% of the time)

Aluminum flashing is one of the most commonly used materials for roof flashing. It’s lightweight, easy to work with, and corrosion-resistant. Aluminum is an excellent option for areas with moderate climates, as it holds up well against rain and wind. However, it’s not the best choice in coastal regions with saltwater exposure, as it can corrode over time in harsh conditions.

Best for: Flashing around vents, skylights, chimneys, and roof valleys. Our go-to material.

2. Copper Flashing (for higher-end custom builds) is popular among roofing contractors for its durability and aesthetic appeal.

Copper flashing is known for its durability and long lifespan. It’s an excellent material for high-end homes or areas where long-term performance is crucial. Copper naturally resists corrosion and doesn’t rust, making it ideal for high-moisture areas. Over time, copper develops a beautiful green patina that many homeowners appreciate for aesthetic reasons, but its true beauty lies in its performance as a type of roof flashing.

Best for: Flashing around chimneys, valleys, and other critical areas on high-end or historic homes.

3. Galvanized Steel Flashing (also comes in baked-on enamel colors now)

Galvanized steel is coated with a layer of zinc to prevent rust, which makes it an affordable and sturdy option for roofing projects. It’s stronger than aluminum and more resistant to damage from impacts or heavy snow. However, galvanized steel, like aluminum, is best used in areas without excessive saltwater exposure.

Best for: Flashing around chimneys, vents, and roof valleys in moderate climates.

4. Lead Flashing (not used much in CO any longer)

Lead flashing is often used in older homes or situations requiring maximum durability. Lead is highly malleable, making it easy to shape around complex roof penetrations. While it’s excellent at waterproofing, lead flashing is not the most eco-friendly choice, as lead can be toxic. It’s also heavier than other materials, so it may not suit every roof type.

Best for: Flashing around chimneys and in areas with high moisture or wind conditions.

5. Rubberized Asphalt Flashing (for flat and low slope roofs)

Rubberized asphalt flashing is a flexible, self-adhesive material used in areas where traditional flashing materials may struggle to adhere, like around irregular roof penetrations or in extreme weather. It’s also very effective at creating a waterproof seal, which is ideal for low-slope or flat roofs.

Best for: Flat roofs, areas with irregular roof shapes, or areas prone to standing water.

How Damaged or Improperly Installed Flashing Can Lead to Leaks

Flashing is a small but crucial part of the roofing system. If flashing is damaged, improperly installed, or missing altogether, it can lead to some serious issues— roof leaks.

1. Water Penetration

Flashing is designed to direct water away from vulnerable areas. If it’s not installed correctly or damaged over time, water can easily seep under the shingles or tiles and travel into your home. Common leak points are around chimneys, skylights, and roof valleys. These areas are particularly vulnerable.

2. Mold and Mildew Growth

When water gets into your roof, it doesn’t just stay in one spot—it can travel down into the walls and attic, where it’s trapped in dark, warm spaces. This creates the perfect breeding ground for mold and mildew. Over time, mold can damage your home’s structural integrity and create health hazards. This is why preventing leaks through proper flashing installation is so important.

3. Roof Decking Rot and Structural Damage

If water continues to leak into your roof, it can damage the decking, insulation, and even the rafters of your home. This leads to rot, weakening the structure of your home and potentially causing expensive repairs, making timely roof replacement vital. Flashing that’s not in good condition will accelerate this process.

4. Ice Dams (on Eaves and Rakes)

In colder climates, ice dams can form when melting snow refreezes along the edges of your roof. Improperly installed flashing can exacerbate this problem, leading to water backing up under the shingles, necessitating a roof replacement. This trapped water then leaks into your home, causing damage to both the roof and the interior of your house. Keeping flashing properly sealed can help prevent ice dams from forming in the first place.

Common Flashing Issues and How to Spot Them

Now that we’ve discussed the importance of flashing and how damage can lead to leaks, let’s discuss the common flashing issues to look out for and how to spot them.

1. Cracked or Bent Flashing can severely compromise the integrity of your roof and should be addressed by a qualified roofer.

Flashing is designed to be durable, but it’s not invincible. Over time, flashing can crack or bend due to extreme weather, wear and tear, or poor installation. If the flashing is broken, water can easily slip through the seams and cause leaks, highlighting the importance of roof maintenance.

Signs to look for include gaps between flashing and shingles, visibly bent or cracked metal, and areas where water is pooling around the flashing.

2. Missing Flashing

Sometimes, flashing can become dislodged due to high winds or poor installation. If the flashing is missing, water has a direct pathway into your home. Even a tiny gap in flashing can lead to big problems over time, mainly if it affects the types of roof flashing used.

Signs to look for include exposed roof penetrations (such as around vents or chimneys), gaps in the flashing around roof seams, and water stains inside the attic or on the ceiling.

3. Rust or Corrosion

Flashing materials like galvanized steel or aluminum can rust or corrode when exposed to moisture over time. If the flashing is severely corroded, it can no longer effectively do its job.

Signs to look for include orange rust on metal flashing, discoloration, or flakes of rust around the flashing areas.
