Why Water Is So Difficult to Trace

Water rarely travels in a straight line. Instead, it moves along the easiest path, following:

• Roof layers

• Siding overlaps

• Flashing details

• Structural framing

• Cracks, joints, and fastener holes

• Vapor and pressure differences

A small opening on a roof can show up as a leak in a wall. A window vulnerability can show up as moisture in a floor. A foundation crack can start with drainage issues 20 feet away.

Understanding these patterns is a skill that takes years to build, and it’s why proper diagnostics are critical before repairs begin.

The Keith Weber Company Diagnostic Approach

Before any tools or materials come out, our team conducts a structured series of steps:

1. Exterior and Interior Inspection

We examine the entire building envelope — not just the area where the leak appears.This includes the roof, walls, joints, flashings, decks, drainage pathways, and below-grade elements.

2. Water-Intrusion Testing

We strategically apply controlled water to specific sections of the building to determine where the leak begins, not just where it ends.

3. Moisture Mapping

This helps us identify hidden moisture inside walls, floors, and ceiling cavities.

4. Pressure, Drainage, and Flow Assessment

Many leaks are caused by improper slopes, clogged drainage, or negative pressure pulling water inward.

5. Cause-of-Failure Summary

Before repairs begin, we pinpoint what failed and why — ensuring the solution is the right one, not just a patch.

This process allows us to eliminate guesswork and fix problems at their source, not their symptoms.

Why Proper Diagnosis Saves Money

Without proper diagnostics, property owners often waste money on repairs that don’t address the real cause. Some common scenarios include:

• Replacing a roof when the real problem is flashing

• Caulking a window that’s leaking due to failed building paper behind the wall

• Sealing a deck without addressing the drainage system beneath it

• Patching foundation cracks while ignoring surface drainage issues

When the root cause goes unsolved, the water returns — and the repairs start all over again.

Our diagnostic-first approach helps customers avoid repetitive costs and long-term structural damage.
