In sheet metal roofing, flashing refers to thin, flat pieces of metal (or other waterproof materials) installed to direct water away from critical areas of the roof and prevent leaks. It is essential for protecting vulnerable points, such as joints, seams, and penetrations, where water might otherwise seep into the structure.
Importance of Flashing
- Prevents water intrusion and structural damage.
- Extends the lifespan of roofing systems.
- Enhances overall building integrity by sealing vulnerable points.
Proper installation of flashing is crucial for ensuring a watertight roofing system. If incorrectly installed or damaged, it can lead to leaks, mold, and costly repairs. Professional installation and regular maintenance are highly recommended for commercial and residential projects.
