Condo roof planning

A condo roof rarely fails all at once. It is planned, funded and replaced over years. Here is a path boards and managers can follow so the roof is not a surprise.

This guide covers roofing practice, not legal duties. Your condominium’s declaration, by-laws, reserve fund study and your lawyer or property manager set the rules for decisions and notices.

The roof as a planned expense

A roof is one of the largest common-element items in a building. Condo corporations normally fund these through the reserve fund, which is planned using a periodic reserve fund study. That study estimates the remaining life of the roof and the likely replacement cost. It is a planning tool and not a roof inspection, so its assumptions about the roof should be checked against what is actually up there.

The most useful thing a board can do is to know the condition of the roof before the study asks for a number. A roof inspection report gives the study author facts rather than defaults, and it can move a replacement date either way.

A planning path

  1. Collect what you have

    Original drawings, past roof reports, repair invoices, leak complaints by unit and the roof section of the latest reserve fund study.

  2. Get a condition report

    A roofer or consultant walks the roof, checks moisture and photographs problems. See flat roof inspection and how long a flat roof lasts.

  3. Decide the strategy

    Repair and monitor, coat, replace in phases, or replace at once. See repair or replace.

  4. Write the scope

    A list of items every bidder prices: tear-off, insulation, membrane, flashings, drains, penetrations, terraces, safety and cleanup.

  5. Collect comparable quotes

    Ask for the same scope, unit prices for extras and proof of coverage. See hiring a flat roofer.

  6. Take it to the board and, if needed, owners

    Follow your governing documents for approvals and notices.

  7. Schedule and communicate

    Fix dates, access and a notice to residents before work begins.

Condo-specific details that change the scope

Penthouse and stair-tower walls

Long runs of flashing that are often original to the building. See flashing and seam repair.

Terraces and balconies

Private terraces over living space are separate membrane systems. See rooftop deck waterproofing.

Drains and overflow

Check how many drains there are and whether the overflow routes work. See roof drains and scuppers.

Rooftop equipment

Mechanical, telecom and signage tenants may have rights to the roof. Coordinate before work.

Townhouse condos

Many individual roofs under one corporation may be done in a rolling programme rather than as one project.

Telling residents

Residents accept noise better when they know the dates and the reason. A notice should say what work is planned, the expected dates and hours, which areas such as balconies and parking may be affected, what noise and smell to expect, and who to contact with questions. Many contractors use cold-applied or self-adhered systems where a torch is unsafe; say which method is planned.

After a job, keep the closeout package in the building file: the scope, drawings, product data, the manufacturer’s terms, photos and the maintenance instructions. It will help the next board and the next reserve fund study.

Keeping a new roof healthy

Once the roof is done, book regular checks. A maintenance visit, from $295 per visit before HST, covers drains, seams, flashings and photos. Restrict roof access to named people and trades, and use walk pads to guide them. See the maintenance checklist and apartment building roofs for related planning.

A sample timeline

A common sequence for a condo roof is: inspection in the autumn, scope and quotes over the winter, board decision in early spring, notice to owners, then work in late spring to early fall. Large or phased projects can run longer. The point is to start the process before the roof forces the decision.

If a leak shows up in the middle of that sequence, repair it as a separate item. Do not wait for the project to deal with a leak that is damaging units now.

Keeping owners informed

A short update at the annual meeting or in the newsletter, with a photo of the roof and a simple statement of its age, condition and planned work, prevents surprises when a special project comes up. Owners who see the evidence tend to accept the cost better than owners who hear about it for the first time in a notice.

Keep unit-level leak reports in one list. When two or three units under the same roof area report water, that is the pattern a roofer or consultant needs, and it shows whether the cause is a roof detail, a terrace or a drain.

Questions from boards and managers

Can a roofer help with the reserve fund study?

A roof inspection report with photos and defects is something the study author can use. The study itself is done by the engineer or specialist the corporation hires.

Should we replace the whole roof at once?

It depends on condition and budget. Phased work spreads the cost but can raise the total and needs careful tie-ins between phases.

What do we do in an emergency leak before the project?

Report it, protect the unit, and ask for temporary protection while the permanent plan is made. See flat roof leak repair.
