🔹 Attic Leaks & Moisture Problems

Many homeowners think they have a “roof leak,” but the true cause is often:

• Condensation
• Ventilation issues
• Ice damming
• Moisture buildup

We diagnose the real cause so the problem doesn’t return.

Signs of a Roof or Exterior Leak

Watch for these warning signs:

• Water stains on ceilings or upper walls
• Peeling paint or bubbling drywall
• Water dripping from vents or light fixtures
• Moldy or damp smell in attic
• Soft, sagging, or discolored exterior wood
• Drafts or cold spots around windows
• Water pooling near the foundation
• Stains on siding or brick

If you notice any of these, your home may already have hidden water damage.

How We Diagnose Exterior Leaks

We use advanced tools to pinpoint the exact entry point:

✔ Thermal Imaging

Reveals temperature differences caused by moisture.

✔ Moisture Meters

Pinpoint hidden water inside ceilings and walls.

✔ Drone Roof Inspections

Safe, high-resolution inspections of steep or hard-to-reach roofs.
