Chimney Flashing Repair Services in Montavilla, Roseway, and Hollywood, OR

If you notice rainwater leaking around your chimney, the likely culprit is the chimney flashing. This thin metal barrier seals the gap where your chimney meets the roof, keeping water from sneaking inside. Once flashing cracks, loosens, or rusts through, leaks can travel fast — damaging ceilings, drywall, and even the chimney itself. Our licensed team specializes in diagnosing and repairing chimney flashing issues before they lead to costly water damage. We know how Portland’s constant rain and freeze–thaw cycles wear on structures and exactly how to fix it for good.

Why Chimney Flashing Matters

Flashing isn’t decorative, it’s your chimney’s first line of defense. Proper installation creates a watertight seal between the chimney and the roof. Over time, though, even well-installed materials can loosen or corrode. Once that seal fails, rainwater can creep in between the brick and roof deck, causing leaks that often appear far from the actual source — in ceilings, walls, or around fireplaces. Left unchecked, the moisture leads to wood rot, mold, and chimney deterioration. A flashing repair today can prevent a major roof or masonry rebuild tomorrow.

Signs Your Chimney Flashing Needs Repair

If you’ve noticed any of these issues, it’s time for an inspection:

water stains or bubbling paint near your chimney
damp ceilings or walls after rainfall
rust streaks on the chimney or roof line
cracked or missing caulking where chimney meets roof
persistent musty odors from the fireplace

Even minor leaks can cause major damage if ignored, especially through Portland’s wet winters.
