Roof leaks in shared buildings, and the records that settle them.
Roof leaks generate more dispute per dollar than almost any other building problem, and the reason is rarely disagreement about the repair. It is the absence of any record about what happened last time.

How responsibility is generally divided
In most BC strata buildings the roof itself is common property, maintained by the strata corporation on behalf of all owners. Damage to interior finishes and contents within a home may fall to the owner or to insurance, depending on the bylaws and the policy structure.
The division is set by the strata plan, the bylaws, and the insurance arrangements in place. It is confirmed against those documents in every case. Nothing here is legal advice, and SENTiNEL is not a licensed property management provider or an insurance adviser.
Why the source matters more than the stain
Water rarely enters directly above where it appears. It travels along framing, decking, and mechanical penetrations before finding a place to drop. The visible interior stain is the exit, not the entry.
That is why targeted investigation matters. Leaks commonly originate at flashings, roof penetrations, parapet transitions, and blocked drainage rather than in the field of the membrane. Identifying which determines whether the answer is a small repair or a capital project, and buildings that guess frequently pay for both.
What documentation should exist for every event
The date reported. The interior location and extent, with photographs. The suspected exterior source, with photographs. Which trade attended, what they did, and what they observed. Whether the repair was verified afterward, and by whom.
Add the roof assembly type, the installation date, the warranty position, and the history of previous repairs in that area. Those five facts convert a recurring argument into a decision.
The pattern nobody sees without a record
Three separate leaks at the same elevation over four years is a failing detail, not three unlucky events. Handled individually, each becomes a small invoice and a closed file. Read together, they justify addressing the detail properly.
Independent oversight helps by keeping that history in one place and rating urgency consistently, so a repeating problem is visible as a repeating problem. Where structural involvement or engineered repair design is required, a qualified engineering professional is engaged directly by the building owner.
Common questions about this topic.
- Who is responsible for a roof leak in a strata building?
- In most BC buildings the roof is common property and the shared responsibility of the strata corporation, while damage inside a home may involve owner insurance. Responsibility depends on the strata plan, the bylaws, and the insurance arrangements, so it is confirmed against those documents rather than assumed.
- Why do roof leak disputes take so long to resolve?
- Because two facts are usually missing: where the water actually entered, and what the maintenance history of that area is. Without documentation, the discussion becomes opinion, and opinion is slow.
- Does a leak mean the roof needs replacing?
- Not necessarily. Many leaks originate at flashings, penetrations, or drainage rather than the field of the roof. Determining which is the difference between a targeted repair and a capital project.
- What should be documented after a roof leak?
- The date, the interior location and extent, the suspected exterior source, photographs of both, the trade attending, what was done, and whether the repair was verified. That record is what settles the next question about the same area.
