Understanding Metal Roof Edging
Metal roof edging serves as a protective barrier for the edges of your roof. It is typically a metal strip installed at the roof’s perimeter, providing structural integrity and enhancing the roof’s visual appeal. Beyond aesthetics, the primary function of metal roof edging is to manage water runoff effectively, directing it away from the fascia and into the gutter system.
Types of Metal Roof Edging
Drip Edge
Drip edges are a fundamental component of metal roofs, designed to divert water away from the roofing material and prevent moisture from seeping under shingles or roofing panels. They are available in various materials, including aluminum, galvanized steel, and copper, each offering unique benefits.
Fascia Edge
Fascia edges cover the roof’s perimeter, protecting the rafters and roof sheathing from exposure to the elements. They enhance the overall appearance of the roof while providing essential support for the gutter system.
Coping Edge
Coping edges are installed on parapet walls and serve as a cap that protects the roof from moisture intrusion. They help prevent wind uplift and are typically made from durable materials like aluminum or galvanized steel.
Gravel Stop
Gravel stops are used primarily in low-slope roofing systems. They prevent gravel from washing away while directing water toward the drainage system, ensuring the longevity of the roofing materials.
Lineal Edge
Lineal edges are pre-manufactured metal systems designed for easy installation, commonly used in EPDM or TPO roofing systems. They provide a clean, finished look while serving as an effective barrier against water infiltration.
Installation of Metal Roof Edging
Proper installation of metal roof edging is crucial for ensuring its effectiveness. Here are the steps to install drip edge on a metal roof:
Step 1: Gather Necessary Tools and Materials
Before starting your installation, gather the required tools, including a measuring tape, chalk line, roofing nails, a hammer, and the metal drip edge material.
Step 2: Measure and Cut
Measure the length of the roof edges to determine how much drip edge material you need. Cut the metal strips to the required lengths using tin snips or a metal cutting saw.
Step 3: Position the Drip Edge
Position the drip edge along the eaves of the roof, ensuring that it extends over the edge to allow for proper water drainage. Use a chalk line to mark the placement for accuracy.
Step 4: Secure the Drip Edge
Secure the drip edge using roofing nails, placing them approximately 12 inches apart. Ensure that the nails are driven flush to avoid damaging the metal.
Step 5: Overlap Sections
When installing multiple pieces of drip edge, overlap the sections by at least 2 inches to ensure a watertight seal. Seal the joints with roofing sealant for added protection.
Step 6: Inspect the Installation
After installation, inspect the drip edge to ensure it is secure and properly aligned. Check for any gaps or misalignments and make adjustments as necessary.
Maintenance of Metal Roof Edging
Regular maintenance of your metal roof edging is essential to prolong its lifespan and ensure optimal performance. Here are some tips for maintaining your metal roof edging:
Regular Inspection
Conduct regular inspections of your roof edging, especially after severe weather events. Look for signs of rust, damage, or misalignment, and address any issues promptly.
Cleaning
Keep the metal roof edging clean by removing debris, leaves, and dirt. Use a soft brush or cloth to clean the surface, and avoid harsh chemicals that could damage the finish.
Painting
If your metal roof edging is painted, consider repainting it every few years to prevent rust and maintain its appearance. Use high-quality exterior paint suitable for metal surfaces.
Repairing Damage
Address any damage to the metal roof edging immediately to prevent further deterioration. Use roofing sealant to fill small cracks or gaps, and replace any heavily damaged sections.
