Types of Chimney Flashing Materials We Use

We use different materials for chimney flashing based on durability and cost. Each material has unique strength, resistance to weather, and maintenance needs. Understanding these helps us choose the right one for each job.

Aluminum Flashing

Aluminum flashing is lightweight and easy to work with. It resists rust and corrosion well, making it a common choice for many homes. This material bends easily, allowing a tight fit around chimney bases.


However, aluminum is less durable than some other metals. It can dent or crack in severe weather or impact. This makes it a better option for areas with mild climates or when budget is a concern.


We prefer aluminum where cost and ease of installation matter most. It needs regular checks to ensure no gaps or damage form over time.

Copper Chimney Flashing

Copper flashing is highly durable and lasts many years without rusting. It can handle extreme weather, including heavy rain and snow, without damage. Copper also forms a strong seal around the chimney.


This material is more expensive but offers excellent protection and low maintenance. Over time, copper develops a green patina. Some homeowners like this look, while others may not.


We recommend copper for homes requiring long-lasting, low-maintenance flashing. Its strength makes it suitable for challenging weather conditions.

Galvanized Steel Flashing

Galvanized steel flashing combines strength and affordability. It has a protective zinc coating that helps prevent rusting. This makes it a reliable choice in wet climates.


The steel is heavier and stiffer than aluminum, which can make installation more complex. Over time, the zinc coating can wear down, increasing the chance of rust if not maintained.


We use galvanized steel when a durable and cost-effective option is needed. Routine inspections are important to catch early signs of corrosion or damage.

Our Chimney Flashing Repair Process

We follow a clear and thorough process to fix chimney flashing. Our method focuses on careful inspection, choosing the right materials, and performing each repair step with attention to detail and safety.

1. Initial Inspection and Assessment


We start by closely examining the chimney area to find any damage or weak spots in the flashing. This includes checking for cracks, rust, or loose seals that could let water in. We also inspect the surrounding roof to see if it has any impact on flashing problems.


Our team uses special tools to measure and test tightness and water resistance. We look for signs of leaks inside the home, like stains or dampness. This helps us decide exactly what kind of repair is needed.



2.  Material Selection and Preparation


Once we know the problem, we pick materials that fit the chimney and roof type. Most often, we use durable metals like aluminum, galvanized steel, or copper for long-lasting protection. The choice depends on weather, roof style, and budget.


Before starting repairs, we prepare the site by cleaning away dirt, old sealant, and rust. This ensures that new materials stick properly and last longer. We cut and shape flashing pieces to match the chimney shape exactly.



3. Step-by-Step Repair


Our repair work follows precise steps to secure the flashing and prevent leaks. First, we remove any damaged or loose flashing carefully to avoid further harm. Next, we place the new flashing in layers, overlapping to direct water away from the chimney.


We then fasten the flashing with corrosion-resistant nails or screws and seal all edges with high-quality roofing cement or sealant. Finally, we check the entire area for gaps or weak spots and test to confirm water tightness.

Preventative Maintenance for Chimney Flashing

Taking care of chimney flashing helps stop leaks and costly damage. We focus on practical steps you can take throughout the year to keep the flashing in good shape and spot problems early.

Regular Inspection Tips

We recommend checking chimney flashing every few months. Look for cracks, rust, or loose edges where the flashing meets the roof and chimney. These spots are common places for water to get in.


Use a flashlight and binoculars if you can’t get close. Pay close attention after storms or heavy rain, since damage is more likely then.


If you find any issues like gaps or rust, mark them and arrange for repair quickly to avoid bigger problems.

Seasonal Maintenance

Before winter, clear leaves, dirt, and debris around the chimney base. This prevents water from pooling and freezing, which can cause flashing to crack.


In spring, wash the flashing with mild soap and water to remove grime and check for any freeze damage.


Also, check the sealant around the flashing. If it’s cracked or missing, reseal with a high-quality, weather-resistant product.


Doing this keeps the flashing strong through temperature changes and weather cycles.
