Roof flashing is an essential component of any building's roofing system, serving as a critical barrier against water infiltration and potential damage. It's designed to redirect water away from vulnerable areas, such as joints, valleys, and transitions, where leaks are more likely to occur. There are different types of roof flashing, each with its own benefits.

One type of roof flashing is called step flashing. It's commonly used along the sidewalls of a building, where the roof meets the vertical surface. Step flashing consists of individual pieces of metal that are overlapped and integrated with the shingles or other roofing material. This creates a watertight seal that prevents water from seeping into the building. The main benefit of step flashing is its ability to provide a continuous and reliable barrier against water intrusion.

Another type of roof flashing is known as counter flashing. This type of flashing is typically installed on top of step flashing to further protect the joint between the roof and sidewall. Counter flashing is designed to cover the top portion of the step flashing and is often made of metal or other durable materials. Its primary benefit is that it adds an extra layer of protection to the vulnerable area, ensuring that water doesn't penetrate the roof system.

Types of Roof Flashing Materials

Different types of roof flashing materials offer distinct advantages and disadvantages, and understanding their pros and cons can help homeowners and professionals make informed decisions.

Here are three common types of roof flashing materials:

Material Pros Cons
Aluminum – Lightweight and easy to work with <br> – Resistant to corrosion <br> – Affordable – Less durable than other materials <br> – Can be prone to denting
Copper – Highly durable <br> – Resistant to corrosion <br> – Aesthetically pleasing – Expensive <br> – Requires skilled installation <br> – Prone to theft due to high scrap value
Lead – Excellent malleability <br> – Long-lasting <br> – Easy to shape and form – More expensive than other materials <br> – Potential health hazards if not handled properly <br> – Can be stolen due to high scrap value

Each material has its own strengths and weaknesses. Aluminum is a popular choice due to its lightweight nature and affordability, but it may not be as durable as other options. Copper, on the other hand, offers excellent durability and a visually appealing aesthetic, but it can be quite expensive and requires skilled installation. Lead is known for its malleability and longevity, but it comes with a higher price tag and potential health risks if mishandled.
