Three Contractors Looked. None Found It.

Robert Mitchell had a water stain in his upstairs bedroom. Three different contractors came out. All three said, "It's the flashing around your chimney." Two of them replaced the flashing.

Two months later, after the next heavy rain, the stain was bigger.

When John Holland climbed onto Robert's roof, he didn't go straight to the chimney. He followed the water. The stain was near the west wall. The chimney was center of the house. Water doesn't run uphill.

The actual problem? A nail that missed a rafter during installation—twelve feet from where the water showed up inside.

Water enters at one point, travels along rafters or between layers, and shows up somewhere completely different. Finding the actual source requires understanding how water moves through roof assemblies.

We don't guess. We trace. We use infrared cameras to find hidden moisture. We look at roof slopes, understand water flow patterns, and find the exact entry point. Then we fix that spot—not everything between the entry point and where you see the stain.

Our Leak Detection Methods

Water Flow Analysis

We understand how water travels through roof systems. The leak is usually uphill from the stain.

Infrared Scanning

Thermal imaging reveals hidden moisture in insulation and decking before it causes visible damage inside.

Systematic Inspection

We check all penetrations, flashings, valleys, and vulnerable areas in the likely water path.

Photo Documentation

We show you exactly where water is entering and explain why it's showing up where it is inside.

Common Hidden Leak Sources

  • Failed Flashing

    Around chimneys, skylights, vents, and wall intersections—the #1 source of roof leaks

  • Valley Problems

    Roof valleys channel massive water flow. Small defects become big leaks fast

  • Penetration Seals

    Plumbing vents, exhaust pipes, and roof-mounted equipment often have deteriorated seals

  • Installation Errors

    Missed nails, improperly sealed shingles, and shortcuts that create leak paths

  • Ice Dam Damage

    Previous ice dams can lift shingles and compromise seals, creating leaks during rain

Stop Guessing. Find the Actual Leak.

Every day you wait, that leak is causing more damage. We'll find the exact source and fix it right the first time.
