Most leaks we trace are not in the field of the roof. They are at a flashing — a wall, chimney, skylight or penetration.
Sidewalls and headwalls, chimneys, skylights, valleys, plumbing vents, and the transition where a flat section meets a slope.
Old flashing and pipe boots that get reused during a re-roof are the single most common reason a brand-new roof leaks. New covering, old detail, same leak.
New flashing, drip edge, valley metal and pipe boots specified in the written scope — not reused.
