Flashing fails fast in Dallas heat. Summers push metal to expand and contract every day, popping the old sealant around chimneys and pipe boots. I see it most in East Dallas and Lake Highlands homes built before 1990 where the original lead has cracked. We replace it with new lead sheets bedded in butyl tape so it moves with the roof instead of tearing again.
Cheap crews often skip the step flashing on roof-to-wall joints. That lets wind-driven rain from our mild winters push water under the shingles. In Uptown Dallas and Oak Lawn we pull the first two courses, slip in new step flashing, and re-nail everything before the next storm hits. Permits are pulled when the job hits the decking layer.
Hail hits hard in North Dallas and Lake Highlands. Dents in the flashing let water sit and rust through by the next summer. We cut out the damaged pieces, install new galvanized sections with hemmed edges, and seal every seam with high-temp caulk rated for 200-plus degrees. That stops the rust before it starts.

How it works
- 1
Inspect and mark
We climb the roof, find every failed flashing joint, and mark the cuts with chalk. Takes 30 to 45 minutes.
- 2
Remove old material
Cut out cracked lead or rusted steel, pull nails, and clean the deck. We protect shingles so nothing else gets torn.
- 3
Install new flashing
Bed new lead or galvanized in butyl tape, slip step flashing under shingles, and seal every edge. One to three hours depending on length.
- 4
Test and clean
Run water over the repair and check inside the attic. Haul debris off site before we leave.
Pricing
Most flashing repairs land between $450 and $1,800 once we see access and how much deck needs work.
