Roof Flashing

Residential roofing is typically made up of a multitude of materials and surfaces whose primary task is to maintain a barrier between the interior and the weather. The most pervasive and difficult weather element to control is water. Roof flashing is usually the last line of defense in the battle against water penetration.

Flashing forms the intersections and terminations of roofing systems and surfaces, to thwart water penetration. The most common locations for roof flashing are at valleys, chimneys, roof penetrations, eaves, rakes, skylights, ridges, and at roof-to-wall intersections.

Our flashing is all custom designed for your application and need.

Typical Roofing Flashing

Metal flashing helps seal out water from many critical spots on a home's roof, including valleys, around chimneys and vent pipes, beside dormer walls, and along the rakes and eaves.


For any covering to be effective, moisture entry points must be adequately flashed and sealed, and other water-shedding components must be properly installed and maintained.


Roof coverings and related flashing must be installed to prevent moisture infiltration. Flashing is required at wall and roof intersections, changes in roof slope or direction, around roof openings, and at gutters.
