Strata Roofing: How to Prevent Winter Leaks in Multi-Family Buildings

When it comes to maintaining multi-family properties, few challenges are as urgent or costly as winter roof leaks. For strata managers and property owners, the cold and wet months bring heightened risks of water intrusion, property damage, and disruptive repairs. At Citadel Roof & Building Maintenance, we understand the unique needs of strata properties across Greater Vancouver and the Lower Mainland. Our expert team has over 15 years of experience helping residential complexes stay leak-free all year. Here’s how proactive strata roofing maintenance can prevent winter leaks and protect your investment.

Why Are Winter Roof Leaks Common in Strata Properties?

Multi-family buildings are particularly susceptible to winter leaks due to their size, complex roofing layouts, and high occupancy rates. Accumulated moisture from rainfall and melting snow can exploit even tiny vulnerabilities in older or poorly-maintained roofs. Blocked gutters, damaged flashing, aging membranes, and previous repair oversights can also contribute to leaks, putting units and tenants at risk. When undetected, water infiltration can lead to costly repairs, mold growth, and structural damage.

Key Areas Where Winter Leaks Start

Understanding where leaks typically originate can help you develop a targeted maintenance strategy. In strata buildings, the most common problem areas include:

• Flat or low-sloped roof sections where water can pool.
• Roof transitions and joints, such as around skylights, vents, and HVAC units.
• Flashing at walls, chimneys, and parapets.
• Gutters, drains, and downspouts clogged with debris.
• Areas with old or failing membrane, shingles, or torch on roofing material.

Prevention Starts with Proactive Maintenance

The best way to prevent winter leaks is with proactive, professional maintenance—well before the stormy weather arrives. At Citadel Roof & Building Maintenance, we recommend the following steps to keep your strata property dry and secure:

1. Schedule a Comprehensive Roof Inspection

A professional inspection is the cornerstone of leak prevention. Our trained specialists assess the entire roofing system, checking for cracks, lifted seams, worn membranes, and blocked drainage. Regular inspections allow early detection of potential problems, so minor issues can be fixed before they become emergencies.

2. Clean Gutters and Downspouts

Clogged gutters are a leading cause of roof leaks in winter. When water can’t drain properly, it can back up under roofing materials, penetrate insulation, and seep into living spaces. We recommend thorough gutter cleaning at least twice a year, especially before and after the rainy season, to ensure unobstructed water flow.

3. Repair Damaged Flashing and Seals

Flashing around vents, skylights, and wall joints is a critical defense against leaks. Over time, flashing can rust, deteriorate, or become misaligned—allowing water to enter. Our team replaces or repairs damaged flashing and reseals vulnerable joints, ensuring a continuous water barrier.

4. Address Membrane and Shingle Wear

For strata properties with torch on roofing, flat roofs, or composite shingles, inspecting the membrane or shingle surface is vital. Look for blisters, cracks, or areas where the roofing material is missing granules. Prompt repairs can extend the life of your roof and prevent leaks from developing in high-traffic or exposed areas.

5. Implement a Preventative Maintenance Program

A regular maintenance plan takes the guesswork out of roof care. Citadel offers customized programs that include scheduled inspections, cleaning, minor repairs, and detailed reporting. These services give strata councils peace of mind and can help satisfy insurance and warranty requirements.

6. Educate Residents and Managers

Encourage occupants and property managers to report any signs of water staining, drips, or musty odors promptly. Early reporting allows for fast action and minimizes the extent of damage.
