What is Corner Flashing Used for?

Corner flashings are essential components in building construction, providing a waterproof seal at the intersection of walls and roofs. By preventing water from penetrating joints, they play a crucial role in maintaining the structural integrity of a building. These flashings are particularly important in areas where two surfaces meet at an angle, such as the corners of a structure, ensuring that water is effectively diverted away from vulnerable areas.

The Purpose of Corner Flashing

Corner flashings are essential components in building construction. Their main purpose is to prevent water from penetrating into the structure, which could lead to damage from rot, mould, and corrosion.Corner flashings help protect the underlying materials, such as wood or masonry from the elements. This extends the life of the building by reducing the risk of deterioration due to water exposure.

What are Common Materials used for Corner Flashings?

If you’re diving into construction, you’ll find that some common materials for corner flashing are:

• Lead
• Aluminium
• Copper
• Steel
• Asphalt

Lead has been a go-to choice for flashing over the years, thanks to its impressive durability and flexibility.

When Should Flashing be Used?

When it comes to exterior wall corners, flashing plays a crucial role. It’s installed where two walls meet, especially at those angled corners of a building. This clever addition helps to channel rainwater away from those joints, keeping it from seeping into the walls.

Flashing is commonly placed around windows and doors corners to fill in any gaps between the frame and the wall. This little detail is essential for keeping water out, which helps prevent damage.

And what about roof to wall junctions? Here, corner flashing is key. It stops water from trickling down the wall and into the structure when the roof meets the wall at a corner. This is especially vital in regions that experience heavy rainfall or snowfall.

Tools needed to install a corner flashing

• Lead Corner flashing
• Tape measure
• Hammer or roofing nails
• Sealant or roofing cement
• Tin snips (for cutting flashing)
• Level or square (for accuracy)
• Ladder (if needed)

Steps for Installing Corner Flashing:

• Prepare the Area:
• Apply Sealant
• Position the Flashing
• Nail the Flashing
• Seal the Edges
• Check for Proper Alignment
• Allow to Dry
• Inspect the Installation

By following these simple steps, you can install corner flashing the right way and make sure your structure’s corners are effectively waterproofed.

Flashing Maintenance

Taking a good look at the corner flashing for any signs of damage is important for ensuring your roof stays watertight and properly sealed. While you’re up there inspecting the roof, keep an eye out for any gaps or cracks. Pay special attention to the edges where the flashing connects with the wall or the roof itself. If you spot any gaps, cracks, or holes, it could mean there’s some damage or wear that needs addressing.

What are the Benefits of Flashing?

When it comes to construction and roofing, correct corner flashing installation and maintenance can make a world of difference. Here are some key benefits:

• Waterproofing and Leak Prevention: Think of corner flashing as a protective shield that keeps water from sneaking into those vulnerable spots, like wall corners.

• Protection Against Mould and Rot: Water that gets trapped in corners can create a perfect breeding ground for mould, mildew, and rot in your walls or roofing materials. Corner flashing steps in to ensure that water is channelled away properly, significantly lowering the risk of long-term damage.

• Increased Durability of the Structure: When flashing is installed correctly, it increases the overall durability of the building. By reducing water damage, it helps maintain the integrity of construction materials, which can extend their lifespan.

• Energy Efficiency: Corner flashing also plays a role in keeping your building energy-efficient. By preventing water from infiltrating the building, it helps avoid drafts, moisture buildup, and insulation issues. Keeping these areas dry can lead to better energy performance.

• Improved Aesthetic Appeal: Nobody likes unsightly stains or discoloration from water seeping into corners. Corner flashing helps keep your structure looking sharp and well-cared for.

• Enhanced Building Resale Value: A property with well-maintained flashing is less likely to suffer from water damage, making it more appealing to potential buyers. Properly installed flashing can really increase the overall value of your home or building.

In a nutshell, corner flashing is essential for maintaining the long-term health and functionality of a structure, ensuring it stands strong for years to come.
