Roof Flashing Repair in Dunwoody, GA

Flashing is one of those things most homeowners never think about until something goes wrong. It's just thin pieces of metal, right? How important can it be?

Turns out, very important. Flashing is what keeps water from getting in at all the vulnerable spots — where your roof meets a wall, around the chimney, in the valleys, around vents and pipes. When flashing fails, leaks happen.

Signs Your Flashing Might Be the Problem

If you're seeing water stains or leaks near any of these areas, flashing is probably the culprit:

• Around your chimney
• Where a roof meets a wall (like over a porch or addition)
• Around skylights
• In roof valleys
• At the edges of your roof (drip edge)

Why Flashing Fails

A few things cause flashing problems:

Age and weather. Georgia's heat, cold, and humidity take a toll. Metal expands and contracts with temperature changes, and over time this can cause it to pull away from the surfaces it's supposed to seal.

Poor installation. We see this a lot. Someone installed flashing incorrectly years ago — wrong type, wrong technique, too much caulk instead of proper overlapping — and now it's failing. Caulk is not a substitute for proper flashing installation, but a lot of roofers treat it like it is.

Storm damage. High winds can lift and bend flashing. Hail can dent it. Debris can knock it loose.

How We Fix It

Sometimes flashing just needs to be re-secured and re-sealed. Sometimes it needs to be completely replaced. We'll assess what you've got and give you an honest recommendation.

For chimney flashing, we do a two-piece system — step flashing that weaves into the shingles, plus counter flashing that's set into the mortar joints. This creates multiple layers of protection instead of just relying on one piece of metal and some caulk.
