Characteristics of metal flashings:

Material:
• Galvanized steel – Corrosion-resistant, durable, and strong.
• Aluminum – Lightweight, corrosion-resistant, and easy to shape.
• Copper – Extremely durable, develops a patina over time that provides additional protection.
• PVC and other composite materials – Resistant to chemicals and weather conditions.

Shape and design:
• Profiled sheets – Available in various shapes to adapt to different parts of the roof and facade.
• Flat sheets – Flat sheets that can be bent according to requirements.

Surface treatment:
• Galvanized – Extra protection against corrosion.
• Coated – Painted or plastic-coated sheets for additional protection and aesthetic appeal.

Advantages of metal flashings:

Protection from weather elements
•Prevent the infiltration of water, snow, and wind into the building structure.
•Maintain the integrity and longevity of the roofing system.

Aesthetics:
•Provide a finishing aesthetic look to the roof and facade.
•Available in various colors and finishes to match the building’s design.

Functionality:
•Facilitate water runoff from the roof and prevent the formation of puddles.
•Adapt to different roof structures and slopes.

Easy installation and maintenance:
•Relatively easy to install and maintain.
•Durable materials reduce the need for frequent repairs.

Applications for metal flashings:

Roof Joints:
• VFlashings around chimneys – Sealing joints around chimneys to prevent water penetration.
• Ridge and hip joints – Protecting the joints at the roof’s peaks.
• Roof windows and ventilation openings – Ensuring waterproofing around windows and vents.

Roof edges and finishes:
• Eavestroughs – Directing water off the edges of the roof to prevent erosion and damage to the facade.
• Valley flashings – Protecting the roof’s valley areas from water infiltration.

Wall and roof joints:
• Vertical and horizontal joints – Sealing joints between walls and the roofing structure.
• Parapets – Protecting the upper edges of walls, especially on flat roofs.

Facade:
• Covers and finishing elements – Aesthetic finishing and protection of exterior walls.
• Water drainage – Facilitating the runoff of water from the facade.

Installation of metal flashings:

Preparation:
• Measuring and cutting the sheets to the required dimensions.
• Preparing the surfaces for attachment.

Installation:
• Positioning the sheets in the correct locations, using appropriate fastening methods (screws, rivets, adhesives).
• Ensuring overlap of the sheets to achieve waterproofing.

Sealing:
• Using sealants and tapes to further ensure waterproofing of joints.
• Inspecting all joints and finishes for proper sealing.

Final touches:
• Checking and refining all parts to ensure both aesthetics and functionality.
• Painting or applying protective coatings as needed.

Maintenance of metal flashings:

Regular Inspection:
• Inspect all joints and flashings for signs of damage, corrosion, or wear.
• Timely replacement or repair of damaged components.

Cleaning:
• Remove dirt, leaves, and debris that could cause water retention.
• Wash and clean the sheets with mild detergents and water.

Repairs and replacement:
• Quick response to minor damage to prevent further issues.
• Replace older or corroded parts to ensure long-lasting protection.

* * * Metal flashings are essential for protecting buildings from weather elements and ensuring the longevity of roofing and facade systems. Their proper installation and regular maintenance ensure both functionality and aesthetics of the building, making them an indispensable part of any structure. * * *
