Flashing is a crucial component in roof construction and repair, yet it often goes unnoticed by homeowners until a problem arises. Understanding its role and importance can help prevent significant damage and costly repairs. With this in mind, we at Nickerson Roofing would like to stress the importance of flashing and where it fits in roof repair.
What is Roof Flashing?
Flashing is a thin, waterproof material installed at various intersections and joints of a roof to direct water away from vulnerable areas. It is typically made from metals like aluminum, copper, or galvanized steel, though flexible materials such as rubber or plastic can also be used. The primary purpose of flashing is to seal gaps and transitions where different roof elements meet, such as around chimneys, skylights, vents, and roof valleys.
Why is Roof Flashing Important?
1) Prevents Water Damage: One of the most critical functions of flashing is to prevent water infiltration. Roofs are subjected to various weather conditions, including heavy rain, snow, and ice. Water can seep into gaps and joints, leading to leaks and structural damage. Flashing acts as a barrier, ensuring that water is channeled away from these vulnerable areas, reducing the risk of leaks and water damage inside the home.
2) Protects Roof Structure: Properly installed flashing helps protect the underlying roof structure from rot and decay. By preventing water from penetrating beneath the shingles or roofing material, flashing helps preserve the integrity of the roof deck and rafters. This protection is essential for maintaining the overall durability and longevity of the roof.
3) Reduces Mold and Mildew: Water infiltration can lead to mold and mildew growth, which can pose health risks and cause further damage to the roof and home. Flashing helps minimize moisture accumulation by directing water away from the roof’s vulnerable spots, thereby reducing the risk of mold and mildew growth.
4) Enhances Roof Longevity: Flashing contributes to the overall longevity of the roof by preventing water-related damage and deterioration. When flashing is correctly installed and maintained, it can extend the lifespan of the roof, saving homeowners from frequent repairs and replacements.
Common Roof Flashing Issues
Despite its importance, flashing can encounter issues that require attention. Common problems include:
Improper Installation: Flashing must be installed correctly to function effectively. Incorrect installation, such as gaps or improper sealing, can lead to water infiltration and damage.
Corrosion: Metal flashing can corrode over time, especially if it is exposed to harsh weather conditions. Corrosion can compromise the effectiveness of the flashing and lead to leaks.
Damage from Weather: Flashing can be damaged by severe weather, such as high winds or hail. Regular inspections can help identify and address any damage promptly.
Maintaining & Repairing Flashing
Regular roof inspections are essential to ensure that flashing remains in good condition. Homeowners should check for signs of damage, such as rust, gaps, or loose sections. If any issues are detected, timely repairs are crucial to prevent further damage. Repairing or replacing flashing typically involves:
Cleaning: Removing debris and dirt from the flashing to ensure a proper seal.
Sealing: Applying roofing cement or sealant to address any gaps or cracks.
Replacing: Replacing damaged or corroded flashing with new material.
