Your roof’s flashing is one of its most critical — and most commonly overlooked — components. Flashing is the metal material installed around chimneys, skylights, vents, and roof valleys to prevent water from penetrating at those vulnerable joints. In Longmont’s climate, flashing failure is one of the leading causes of roof leaks.
Types of Roofing Flashing We Repair in Longmont
- Chimney flashing — step flashing and counter flashing around chimney base
- Skylight flashing — integrated or surface-applied around skylight frames
- Valley flashing — open or closed metal at roof plane intersections
- Pipe boot flashing — rubber or metal collars around roof penetrations
- Drip edge — along eaves and rakes to direct water into gutters
- Wall flashing — where roof meets vertical walls
How Flashing Fails in Colorado
Colorado’s freeze-thaw cycles expand and contract metal flashing repeatedly over winters. Over time, this causes cracks, separation from sealant, and rust. Hail can also dent and compromise metal flashing. Annual inspections catch these issues before they become leaks.
