What is flashing?
The protective seal that prevents water intrusion at areas such as skylights, chimneys, dormers and vents is called flashing. Flashing is a critical preventive measure for moisture damage when water is most prone to penetrate a roof’s surface.
Where is flashing important?
Flashing is important at all roof penetrations, including edges, valleys, joints and any grooves, gaps, intersections and projections on the roof of any structure.
How can improper flashing damage my roof?
Poor or improper flashing can lead to premature deterioration at roof joints, so it is imperative to have flashing installed correctly when a new roof is installed. Having it done right the first time is one of the best things you can do to preserve your investment.
