Roof Flashing Repair
New metal at valleys, walls, eaves, and penetrations, the joints that decide whether a roof stays dry. Offered by York Roofing Co for homeowners in York, Pennsylvania.
Overview
Roof flashing is the metal and membrane work at every place a roof changes direction or meets something else: valleys, sidewalls, dormers, eaves, rakes, and pipe penetrations. It is a small share of the roof by area and a large share of its leaks.
York Roofing Co repairs roof flashing in York, Pennsylvania, replacing worn or poorly installed metal so water is guided off the roof.
Flashing failures hide in plain sight
Flashing can corrode, pull loose, or be installed in the wrong order so that it channels water behind siding rather than over shingles. Kickout flashing at the base of a roof wall junction is often missing altogether.
Because the roof field looks fine, flashing problems are easy to overlook until a wall or ceiling shows the damage.
Flashing repair can include
Sidewall and step flashing
Where roofs meet vertical walls and dormers.
Valley flashing
Open or closed valley metal and membranes.
Drip edge and kickouts
Edge metal and diverters that steer water into gutters.
Penetration flashing
Vents, pipes, and other openings through the roof.

Local notes for York homeowners
Many York homes have additions, porches, and dormers added over the decades, and each of those connections depends on flashing. Older connections are worth a careful look.
Questions about roof flashing repair
What is kickout flashing?
It is a small angled piece at the bottom of a roof wall junction that turns water into the gutter instead of letting it run behind the siding.
Can flashing be repaired without a new roof?
Yes. Flashing at specific joints can usually be replaced while the surrounding roof stays in place.
