If youre considering a metal roof for your home or business, its essential to understand the importance of flashing and sealing. These critical elements play a significant role in ensuring the longevity and durability of your metal roof. In this blog post, well break down everything you need to know about flashing and sealing for metal roofing.
What is Flashing?
Flashing is a thin piece of metal that is installed on the joints and seams of a roof to prevent water from seeping through. It is typically made of galvanized steel, aluminum, or copper and is installed around roof penetrations such as chimneys, skylights, vents, and valleys. Flashing is crucial for protecting these vulnerable areas from water damage and leaks.
Types of Flashing
There are several types of flashing used in metal roofing, including:
1. Step flashing: This type of flashing is installed on the slope of the roof and overlaps with the roofing material to create a watertight seal.
2. Counter flashing: Counter flashing is installed on top of step flashing to provide additional protection against water intrusion.
3. Valley flashing: Valley flashing is installed in the valleys of the roof where two sloping roof planes meet. It helps channel water away from these low points to prevent leaks.
Proper installation of flashing is essential for ensuring your metal roof remains watertight and leak-free. Its crucial to work with a qualified roofing contractor who has experience installing metal roofing systems to ensure that flashing is installed correctly.
What is Sealing?
Sealing is the process of applying a protective coating or sealant to the seams and fasteners of a metal roof to prevent water intrusion. Sealing helps create a barrier against water and moisture, protecting the roof from leaks and corrosion. It is an essential step in ensuring the longevity of your metal roof.
Types of Sealants
There are several types of sealants used in metal roofing, including:
1. Silicone sealant: Silicone sealant is a popular choice for metal roofing due to its flexibility, durability, and weather resistance.
2. Butyl sealant: Butyl sealant is another commonly used sealant for metal roofing. It offers excellent adhesion and is known for its ability to withstand extreme temperatures.
3. Polyurethane sealant: Polyurethane sealant is a versatile sealant that offers excellent adhesion and durability. It is suitable for a wide range of metal roofing applications.
Properly sealing the seams and fasteners of a metal roof is essential for preventing leaks and ensuring the roof’s longevity. Its important to work with a qualified roofing contractor who uses high-quality sealants to ensure that your metal roof is properly sealed.
Benefits of Flashing and Sealing
Properly installed flashing and sealing offer several benefits for metal roofing, including:
1. Preventing leaks: Flashing and sealing help create a watertight barrier that prevents water from seeping through the roof and causing leaks.
2. Extending the life of the roof: By preventing water intrusion and corrosion, flashing and sealing help extend the lifespan of a metal roof.
3. Enhancing energy efficiency: A well-sealed roof can help improve energy efficiency by preventing air leakage and maintaining a consistent indoor temperature.
