Flat Roof Leaks: How to Spot and Fix Them

Flat roofs are a sleek, modern choice for homes and businesses, offering functional spaces and contemporary design. However, their low slope can make them susceptible to leaks, especially in rainy climates like Vancouver. Identifying and fixing a leak early can save you time, money, and significant property damage. In this guide, we’ll walk you through the telltale signs of a flat roof leak, how to locate the source, and effective solutions to restore your roof’s integrity.

Flat roof leaks often manifest in subtle ways. Look for these common signs:

• Water Stains on Ceilings or Walls: Discoloration or bubbling paint is a sign water has infiltrated your roof structure.
• Ponding Water: Standing water on your roof can indicate poor drainage and increase the risk of leaks.
• Dripping Water: Obvious drips during rainfall are a direct sign of a breach.
• Mold or Mildew: Persistent dampness can lead to mold growth, posing health risks and signaling a leak.
• Damaged Flashing: Cracked or separated flashing can allow water to seep into vulnerable areas.

Finding the origin of a flat roof leak can be tricky since water can travel far from the entry point. Follow these steps:

• Inspect the Interior: Start indoors, tracing water stains or drips to their highest point.
• Check Roof Features: Pay attention to flashing, seams, vents, and HVAC units—common culprits of leaks.
• Examine the Roof Surface: Look for cracks, blisters, punctures, or pooling water on the roof membrane.
• Conduct a Water Test: If the source isn’t obvious, use a hose to simulate rainfall, isolating sections of the roof until the leak is found.

Once you’ve identified the source, follow these steps to repair the leak:

• Clean the Area: Remove debris, dirt, and water from the damaged spot for a clean working surface.
• Patch Small Holes or Tears:
• Use a roofing sealant or patching kit designed for your roof type (e.g., TPO, EPDM, or PVC).
• Apply the patch according to the manufacturer’s instructions, ensuring a watertight seal.
• Repair Flashing:
• Replace or reseal cracked or separated flashing with a waterproof sealant.
• Fix Ponding Water Issues:
• Improve drainage by adding tapered insulation or repairing clogged drains.
• Call a Professional: For large leaks or extensive damage, it’s best to consult a roofing specialist to ensure the roof repair in Vancouver is done correctly.
