Roof & Ceiling Leak Detection
Pinpoint the exact source of roof leaks to prevent water damage and costly repairs with our advanced detection technology.
Find the True Source of Roof Leaks
Roof leaks are often tricky because water can travel far from the actual entry point before appearing on your ceiling. Our specialized roof and ceiling leak detection services use advanced technology to identify the precise location where water is entering your roof, not just where it's dripping inside.
BC's climate, with heavy rainfall and snow, makes roofs particularly vulnerable to leaks. Our non-invasive detection methods save you from unnecessary roof removal and help contractors make targeted repairs, saving you time and money.

Common Roof Leak Entry Points
Understanding where leaks commonly occur helps us focus our detection efforts.
Roof Penetrations
Chimneys, vents, skylights, and plumbing stacks are common leak entry points due to failed flashing.
Valleys & Joints
Roof valleys and joints where two roof planes meet are vulnerable to water accumulation and leaks.
Damaged Shingles
Missing, cracked, or worn shingles allow water to penetrate the underlying roof structure.
Flashing Failures
Corroded, damaged, or improperly installed flashing around roof features and walls.
Ice Dams
Ice buildup at roof edges preventing proper drainage and forcing water under shingles.
Flat Roof Ponding
Water pooling on flat or low-slope roofs eventually finding weak points in the membrane.
Signs You Have a Roof Leak
Ceiling Stains
Water stains, discoloration, or rings on ceilings indicating water has penetrated the roof.
Dripping Water
Active dripping from ceilings or light fixtures, especially during or after rain.
Sagging Ceilings
Ceiling areas that appear to sag or bulge from water accumulation above the drywall.
Mold or Mildew
Visible mold growth or musty odors in upper rooms or attic spaces indicating moisture presence.
Exterior Damage
Missing shingles, damaged flashing, or deteriorated roof materials visible from ground level.
Attic Evidence
Water stains, damp insulation, or light penetrating through roof boards in attic spaces.
Advanced Roof Leak Detection Technology
We use specialized equipment designed for roof leak detection:
- Infrared Thermography: Identifies moisture in roof decking and insulation that's invisible to the naked eye.
- Drone Thermal Inspection: Safely inspects large or steep roofs from above without putting technicians at risk.
- Moisture Meters: Measures moisture content in roof materials to trace leak paths and assess damage extent.
- Electronic Leak Detection: For flat roofs, uses electrical current to locate membrane breaches precisely.
