Roof & Balcony Leak Inspection

Comprehensive inspection of roofing systems, balconies, and elevated structures. Protect your property from Vancouver's heavy rainfall with professional leak detection.

Why Roof & Balcony Inspections Are Critical in BC

Metro Vancouver receives over 1,150mm of rainfall annually, with the majority falling between October and April. This prolonged exposure to moisture puts tremendous stress on roofing systems and balcony waterproofing.

Flat Roof Challenges

Ponding water, membrane degradation, and seam failures are common in Vancouver's wet climate.

Balcony Membranes

UV exposure combined with moisture causes membrane cracking and delamination over time.

Drainage Issues

Clogged drains and scuppers lead to water pooling and eventual penetration into living spaces.

Freeze-Thaw Cycles

Winter temperature fluctuations expand and contract materials, accelerating failure.

Comprehensive Roof & Balcony Assessment

Roofing Systems

  • Membrane condition and integrity
  • Seam and flashing inspection
  • Drainage system evaluation
  • Penetration sealing (vents, pipes)
  • Ponding water assessment
  • Substrate condition check

Balcony Structures

  • Waterproof membrane testing
  • Floor slope and drainage
  • Railing attachment points
  • Expansion joints
  • Perimeter flashings
  • Substrate moisture content

Critical Details

  • Wall-to-deck transitions
  • Door threshold assemblies
  • Guardrail post penetrations
  • Drain connections
  • Overlay system integrity
  • Sealant condition

Our Testing Methods

Visual Inspection

Detailed examination of all visible surfaces, seams, flashings, and drainage components. Photo documentation of deficiencies.

Water Testing

Controlled water application to suspect areas while monitoring interior spaces for active leaks. ASTM standard test protocols.

Moisture Scanning

Non-invasive moisture meter readings to detect trapped water within substrate and identify extent of water damage.

Thermal Imaging

Infrared cameras reveal moisture patterns, membrane delamination, and insulation deficiencies not visible to the naked eye.

Core Sampling

When necessary, targeted core samples assess membrane thickness, substrate condition, and waterproofing effectiveness.

Drainage Flow Testing

Evaluation of drainage capacity, proper slope, and scupper/drain functionality under simulated rain conditions.

Common Roof & Balcony Problems We Find

Cracked or blistered waterproof membranes
Failed sealants at penetrations and joints
Inadequate or missing flashings
Ponding water from improper drainage slope
Delaminated membrane overlays
Corroded or loose railing attachments
Clogged drains and scuppers
Deteriorated substrate materials
Missing or damaged expansion joints
Improper door threshold assemblies
UV-degraded coatings and sealants
Structural deflection causing drainage problems

Don't Let Roof & Balcony Leaks Damage Your Property

Vancouver's climate is hard on roofing and balcony systems. Regular professional inspections prevent costly water damage and extend the life of your waterproofing systems.
