Roof Flashing Repair in Johns Creek, GA

Water appearing near your chimney? Where a second-story addition connects to the original house? Around a dormer or skylight? Nine times out of ten, your leak traces back to flashing that's failed.

What Flashing Does

Flashing is shaped metal designed to seal vulnerable points — anywhere your roof meets something else. Chimneys, walls, skylights, valleys, vent pipes. When it works, you never think about it. When it fails, water finds a direct path inside.

Problem Areas We See Constantly

• Around chimneys — by far the most common failure point
• Where additions or dormers tie into the main roof
• Around skylights
• In valleys where two roof surfaces meet
• Along roof edges (drip edge)

Why Flashing Fails

Temperature cycling. Metal expands in heat, contracts in cold. After years of this, it works loose from surrounding materials. Sealant degrades, gaps form, water enters.

Poor installation. Someone relied on caulk instead of proper overlapping. Wrong flashing profile for the application. Shortcuts that save time initially but fail prematurely. Caulk supplements good flashing — it doesn't substitute for it.

Storm damage. High winds lift and bend metal. Debris dents it. Sometimes storm damage doesn't become obvious until it starts leaking weeks later.

Our Approach

Sometimes flashing just needs resealing and securing. Sometimes it needs complete replacement. We assess what you've got and recommend what makes sense.

For chimney flashing specifically, we do it properly — step flashing interwoven with shingles plus counter flashing set into mortar joints. Two layers of defense rather than one piece and some caulk.
