Wherever vertical surfaces intersect a sloping roof—such as brick chimneys, stucco parapets, skylight curbs, and dormer sidewalls—flashing bridges the joint. Over decades of thermal expansion, seasonal marine layer moisture, and sealant degradation, metal flashings can corrode, separate from masonry, or pull loose, allowing runoff to enter attic framing.

Frequently Asked Questions
Clear, direct answers about roof flashing repair and local Lakewood roofing practices.
Step flashing consists of individual L-shaped metal pieces woven into each course of shingles along a sidewall. Counter-flashing is an overlapping metal piece anchored directly into the masonry chimney or wall that hangs down over the step flashing to prevent water from entering behind it.
Slathering roof tar or mastic over old flashing is a temporary emergency patch that usually fails within one or two seasons. As temperatures shift, the dried tar cracks and traps water behind the metal. Replacing the corroded metal and installing proper underlayment is the only lasting repair.
A kick-out flashing is a specially angled metal diverter installed at the lower edge of a roof-wall junction. It directs heavy water runoff away from the exterior stucco and into the gutter, preventing water from soaking behind stucco and causing hidden wall rot.
Quality galvanized steel flashing typically lasts 20 to 25 years, while premium copper flashing can last 50 years or more. However, the caulking and sealants that hold counter-flashing into masonry reglets generally require inspection and renewal every 7 to 10 years.
Chimneys interrupt roof drainage and catch large volumes of rainwater on their uphill side. Without a properly built sheet metal chimney cricket (saddle) and intact counter-flashing, water pools behind the brickwork and seeps through mortar joints directly into the attic framing.
