RCABC’s Failing Pipe-Boot Bulletin: What Townhouse Strata Owners Should Check

If your townhouse complex has a deteriorating pipe boot, we recommend looking beyond the one leaking location. Identify the flashing, then have comparable installations across the complex assessed. Fixing the reported leak matters, but council also needs to know whether it is dealing with an isolated defect or a repeated component problem.

That distinction is the useful lesson in RCABC’s October 29, 2024 bulletin. For a strata planning autumn roof work in the Lower Mainland, Fraser Valley or Sea-to-Sky corridor, it is a reason to ask a more precise question than “Are the shingles still good?”

The warning concerns a particular type of boot

A pipe boot is the flashing around a pipe where it passes through the roof. The RCABC bulletin describes stepped plastic-rubber boots, designed to be cut or torn to accommodate different pipe diameters. The reported installations were on asphalt-shingle roofs, using flashings that were not proprietary to the shingle manufacturer.

The reported failures affected exposed flashing material and appeared four to eight years after installation. That is the history of those reported cases, not a predicted lifespan for your boots. The bulletin did not establish a definitive cause.

Its RoofStar restriction applied to that flashing type on projects bid on or after October 29, 2024. It was not a province-wide legal ban on rubber, nor a finding about every flat-roof pipe flashing.

For product comparison, use the photographs in RCABC’s bulletin as a reference alongside your contractor’s identification. A similar silhouette is a reason to investigate, not enough to name a manufacturer or declare a product affected.

One failed boot should change the inspection scope

A work order that says “repair leak at unit 12” can leave council without an answer about the rest of the development. Ask for a separate finding on comparable pipe flashings, with locations and condition photographs. Keep the immediate leak response and the wider assessment as distinct items so neither disappears into a vague repair allowance.

A useful on-site record would capture:

• The building and roof location, with an overview and close-up of the flashing.
• Visible splits, missing material or separation around the pipe, including whether damage affects the exposed boot or another part of the detail.
• Product markings where readable, and any supporting installation records.
• Which other locations were inspected, which were inaccessible, and whether the same flashing type was found.

Have a suitably equipped roofing contractor obtain roof-level observations. Council members and residents can contribute existing photographs and leak reports without climbing onto a sloped roof or pulling at suspect material.

The practical distinction is between “no problem observed at the locations inspected” and “every boot has been checked.” Ask the report to say which it means. If access limited the review, council can decide whether to fund the remaining inspection instead of assuming the whole complex is clear.

Read replacement proposals as a complete detail

We would favour a proposal that names the replacement product and explains its connection to the roof over one that simply promises “new metal boots.” Material alone does not describe the finished weatherproofing.

The current asphalt-shingle standard’s penetration provisions address fit, suitability for the slope, and integration of the flange with membrane and underlayment. For owners, the implication is straightforward: the quote should explain work around the base as well as the seal around the pipe. These are RoofStar system provisions, not an installation prescription for every existing roof repair.

Ask the contractor to explain what surrounding roofing must be opened, what will be reinstated, and how concealed deterioration discovered during the work will be documented and priced for a decision. That makes two quotes easier to compare than a single price per boot with undefined inclusions.

An illustrative comparison: one proposal might include only the visible flashing, while another includes opening and reinstating adjacent roofing and documenting the concealed interface. Before calling the second quote expensive, establish whether the first includes that work too.

Confirm acceptance for the actual replacement

Do not use the 2024 bulletin alone as a current product approval list. RCABC’s technical updates still carry the historical restriction, while the current shingle standard also contains conditional provisions for flexible boot flashings. That is not a sound basis for council to approve a like-for-like substitute by appearance.

For work intended to carry a RoofStar Guarantee, have the contractor obtain confirmation from the guarantee provider for the exact proposed product and detail before ordering. The shingle manufacturer’s instructions also need to be addressed. For an existing roof with coverage, have the applicable repair and notice conditions checked before work proceeds; the bulletin alone does not determine that roof’s coverage.

Council’s next decision should be specific: respond to any active leak, establish the extent of comparable deterioration, and approve a defined replacement scope. A failed pipe boot is a reason for targeted investigation, not by itself a verdict that the entire roof needs replacing.

If you need help defining that assessment, discuss a roof inspection with Raven Roofing. Bring the bulletin, available installation records and the locations of reported leaks so the review starts with the right question.
