Roof flashing is one of the most critical components in maintaining the structural integrity of your home. It prevents water from penetrating your roof at vulnerable points, such as valleys, chimneys, and skylights, ensuring that your home stays dry and safe. At Roof Repair Albany NY, we specialize in expert flashing installation and maintenance to protect your roof from water damage.
Why Roof Flashing is Essential
Roof flashing is designed to direct water away from areas where two surfaces meet, such as roof valleys, chimneys, and vents. Without proper flashing, these areas are prone to leaks, leading to water damage, mold, and structural issues. The primary function of flashing is to create a watertight seal that directs rainwater into the gutters and away from the roof.
Fact: Roof flashing is a crucial element in preventing up to 90% of roof leaks, particularly in high-risk areas such as valleys and chimneys.
The Evolution of Flashing Materials
The materials used for flashing have evolved significantly over time. Historically, flashing was made from basic materials like birch bark, especially in early New England homes. As construction practices advanced, sheet metal became the standard. Some common flashing materials used today include:
Lead: Durable but less popular today due to health and environmental concerns.
Copper: A high-end option known for its longevity and aesthetic appeal, often used in historic or luxury homes.
Steel and Aluminum: These are the most commonly used materials today, offering a balance of durability and affordability.
Rubber and Plastic: In some modern applications, rubber and plastic materials are used for flashing around chimneys or skylights, providing a flexible seal.
Key Areas That Require Flashing
Flashing is necessary in several critical areas of your roof, ensuring these points remain watertight.
Valleys: Roof valleys, where two slopes meet, handle large volumes of water. Proper flashing prevents leaks in these high-flow areas.
Chimneys: Chimneys are particularly vulnerable to leaks and require step flashing on the sides, an apron below, and a cricket above to divert water.
Skylights and Dormers: Skylights and dormers require continuous flashing and rubber gaskets to maintain a watertight seal.
Maintaining Your Roof’s Flashing
Flashing can wear out over time, even if your roof is in good condition. For materials like tile or slate, the roof may last longer than the flashing, requiring periodic inspections to ensure no gaps or leaks have developed. It’s recommended that asphalt shingle roofs be inspected every three years, while tile or slate roofs should be inspected every five to seven years.
