The $18,000 Quote for a $900 Problem
Sarah Thompson had water stains on her ceiling. Right next to the chimney. She called a roofing company. They came out, looked around for twenty minutes, and gave her a quote.
$18,000. Full roof replacement. "Your roof is old," they said. "These leaks mean it's time."
Then Sarah called us. John Holland went up with his camera. Showed her exactly what was happening: The flashing where the chimney meets the roof had pulled away. Water was running down the chimney, under the shingles, and into her attic.
"It's the flashing. Not your roof. This is a $900 repair."
We removed the old flashing, installed new step flashing and counter flashing, sealed everything properly. Two guys, four hours. Sarah's roof had another ten years in it.
That was four years ago. Zero leaks. Her ceiling is repainted. And she saved $17,100 by getting an honest assessment.
Common Flashing Problems We Fix
Chimney Flashing
The most common source of roof leaks. Step flashing and counter flashing must work together. When one fails, water gets in. We replace both correctly.
Vent Pipe Flashing
Rubber boots around vent pipes crack and deteriorate over time. Water seeps in slowly, causing hidden damage. Simple replacement prevents expensive rot.
Skylight Flashing
Skylights need proper flashing on all four sides. Poor installation causes leaks that look like they're coming from the skylight itself.
Valley Flashing
Where two roof planes meet, water concentrates. Valley flashing takes the brunt of water flow. Must be installed with proper underlayment and sealed correctly.
Signs Your Flashing Has Failed
- Water stains near chimneys or walls
Discoloration on ceilings or walls adjacent to penetrations
- Visible rust or corrosion on metal flashing
Flashing deteriorates over time, especially if improperly installed
- Separated or lifted flashing
Gaps between flashing and roof surface or chimney allow water entry
- Cracked or missing caulk
Sealant deteriorates faster than metal, creating entry points for moisture
- Leaks only during heavy rain or snow melt
Water finds its way through compromised flashing under pressure
How We Install Flashing Correctly
Step 1: Remove Old Flashing Completely
We don't patch over failing flashing. We remove it, inspect the substrate for damage, and start fresh.
Step 2: Install Proper Underlayment
Ice and water shield goes under the flashing. This creates a secondary barrier that prevents leaks even if the flashing eventually fails.
Step 3: Layer the Flashing Correctly
Each piece must overlap properly so water flows over, not under. Step flashing weaves with shingles. Counter flashing covers the step flashing.
Step 4: Seal Every Joint
Quality sealant at every connection point. Not visible caulk that deteriorates, but proper roofing sealant applied where it matters.
