1) Poor Attic Ventilation

Columbia’s humid summers make attic airflow crucial. Insufficient ventilation traps heat and moisture, leading to mold, rusted nails, and shingle damage.

Tip: Make sure soffit and ridge vents are clear and balanced.

2) Hidden Roof Leaks

Small roof leaks often hide behind insulation or ceiling stains. By the time you notice them, water may have already weakened drywall or framing.

Tip: Regular roof inspections and maintenance help catch leaks before they cause major damage.

3) Grading & Drainage Problems

Flat yards or short downspouts cause water to collect against foundations — one of the top issues found in Mid-Missouri.

Tip: Extend downspouts 6–10 feet and check for soil settling around the foundation.

4) Electrical Panel Defects

Double-tapped breakers, missing covers, or outdated panels can pose safety concerns if left unaddressed.

Tip: A licensed electrician should evaluate any signs of overheating or loose wiring.

5) Plumbing Leaks Under Sinks or in Crawl Spaces

Active leaks, rusted traps, and brittle supply lines are common in areas most homeowners rarely check.

Tip: Early detection prevents water damage and mold growth.

6) Old or Inefficient HVAC Systems

Even systems that “run fine” can be inefficient or near the end of their service life. We check operation, condition, and maintenance history — and recommend professional servicing when needed.

7) Radon Levels Above EPA Guidelines

Mid-Missouri is a known radon zone. Without testing, homeowners can’t know if levels exceed safe limits. AW Inspections provides certified radon testing with clear reports and mitigation guidance.
