Common Rainwater Leak Issues in Low-Rise & Commercial Buildings

Heavy rainfall in Metro Vancouver can reveal hidden weaknesses in building exteriors, roofing, drainage, and foundations. Below, we outline the most common causes of rain leaks in low-rise residential and commercial properties and how AnyLeak can help detect and repair them.

1. Roof Leaks: Preventing Water Intrusion from Above

How Do Roof Leaks Start in Low-Rise & Commercial Buildings?

Low-rise residential and commercial properties typically have flat or sloped roofing systems that are vulnerable to rain leaks due to:

• Deteriorated roofing membranes (EPDM, TPO, or BUR systems)
• Ponding water on flat roofs due to poor drainage
• Cracked or missing shingles on sloped roofs
• Improperly installed or failing flashing around HVAC units, vents, and skylights

Signs of a Roof Leak

• Water stains on interior ceilings or walls
• Mold growth or musty odors in upper-floor units
• Soft spots or bubbling on roof surfaces
• Standing water or clogged drains on flat roofs

How AnyLeak Detects and Fixes Roof Leaks

✔ Infrared thermal imaging and moisture meters to detect hidden leaks
✔ Drone inspections for hard-to-reach commercial roofs
✔ Roof membrane repairs and drainage system improvements

2. Facade & Exterior Wall Leaks: Stopping Water Penetration Through the Building Envelope

How Do Facade Leaks Occur?

Rainwater can seep into exterior walls, stucco, brick, or cladding due to:

• Cracked or deteriorated caulking around windows and doors
• Failed waterproofing membranes behind siding or panels
• Wind-driven rain forcing water behind building facades
• Expansion joint failures allowing moisture penetration

Signs of a Facade Leak

• Peeling or bubbling paint on exterior or interior walls
• Water stains near window and door frames
• Mold or mildew growth on building exteriors

How AnyLeak Detects and Fixes Facade Leaks

✔ Pressure testing and smoke testing to locate leaks
✔ Resealing windows, doors, and facade expansion joints
✔ Installing new waterproof membranes or siding repairs

3. Gutter & Downspout Failures: Preventing Rainwater Overflow

How Do Gutter & Drainage Issues Cause Leaks?

• Clogged gutters cause water to spill over, seeping into walls and foundations
• Disconnected or misaligned downspouts lead to water pooling near the building
• Improperly sloped gutters create standing water that deteriorates roofing materials

Signs of Gutter & Downspout Problems

• Water stains on exterior walls below gutters
• Pooling water around the building’s foundation
• Gutters overflowing even during light rain

How AnyLeak Detects and Fixes Gutter Leaks

✔ Camera inspections of drainage systems to locate blockages
✔ Gutter cleaning, repair, and re-sloping for proper drainage
✔ Extending downspouts to divert water away from the building

4. Window & Door Leaks: Stopping Rainwater from Entering the Building

How Do Windows & Doors Leak?

Improper sealing around windows, doors, and curtain walls allows rainwater to seep in, especially during storms.

Signs of a Window or Door Leak

• Water pooling on window sills or near door thresholds
• Mold growth around window and door frames
• Drafts or visible gaps in weather stripping

How AnyLeak Detects and Fixes Window & Door Leaks

✔ Water pressure testing to identify leaks
✔ Replacing failed sealants and weather stripping
✔ Installing proper flashing around doors and windows

5. Parking Garage & Foundation Leaks: Preventing Water Damage from Below

How Do Foundation & Underground Leaks Occur?

• Cracks in concrete slabs allow groundwater seepage
• Improper drainage systems lead to water accumulation
• Hydrostatic pressure forces water into underground parking garages

Signs of a Foundation or Underground Leak

• Water stains or puddles in underground parking areas
• Efflorescence (white, chalky residue) on concrete walls
• Mold growth and musty odors in lower levels

How AnyLeak Detects and Fixes Foundation Leaks

✔ Moisture mapping and hydrostatic pressure testing
✔ Installing waterproofing membranes and drainage systems
✔ Sealing foundation cracks with epoxy injections

6. Skylight & Solarium Leaks: Stopping Water Infiltration from Overhead Glass Structures

How Do Skylights & Solariums Leak?

• Failed caulking or flashing around skylights
• Condensation buildup leading to water pooling
• Cracked or broken glass panels

How AnyLeak Detects and Fixes Skylight & Solarium Leaks

✔ Sealant and flashing repairs
✔ Installing proper drainage systems
✔ Applying waterproof coatings to glass structures
