Roof Inspection in Downtown Toronto

Yes, including multi-storey commercial, institutional, and mixed-use buildings. We scope the inspection to the building's size and complexity.

Yes. Our reports are formatted with the level of detail most lenders require for commercial building financing.

Yes, when requested, and we sound the slabs rather than only looking at them. Membrane condition at the slab-to-wall joint, the drains, and the railing posts is recorded balcony by balcony along with any delamination in the concrete beneath, so the board can see where the problem is concentrated.

Access coordination, building management notification, and report formatting are more involved for commercial downtown buildings. We handle all of this as standard practice.

Yes. We service a number of downtown buildings on annual or biennial cycles, and each report follows the same format and roof plan as the last, so a property manager can see what has changed since the previous visit instead of reading a fresh assessment every time.

Yes where the assessment requires it, and the cores are patched to full integrity before we leave. A core is the only way to know with certainty what the assembly consists of and whether water has entered the insulation and reached the deck, which is the finding that separates a roof needing recoating from one needing replacement. We use thermal imaging first to identify the likely wet zones so the cores are cut where they will answer something, which keeps the number of penetrations low.

Differences in how quickly areas of the assembly release heat, which reveals where the insulation holds moisture. Wet insulation retains heat longer than dry insulation, so scanning after sunset in suitable conditions maps the saturated areas as distinct patterns. It does not see through the membrane or diagnose a cause, and it is unreliable in the wrong weather. Used properly it tells us where to core and lets us report the extent of a wet assembly by area rather than guessing from where the leak appeared indoors.

Quantified condition data structured for the engineer preparing or updating the study: each assembly identified and assessed separately, condition by zone, moisture extent confirmed by core where relevant, drain and joint condition, sounded delamination areas on parking and balcony slabs, remaining service life, and cost bands broken out by phase. The point is that a board can stage the work across budget years rather than face it as a single number, and the study can rely on measured data rather than an impression.

Most lenders and insurers want an assessment within the last twelve months, and some will accept a slightly older report accompanied by a current update. In practice condition on a commercial roof near the end of its service life can change materially in a single winter, so an older report is genuinely less reliable rather than merely less acceptable. If you are heading into a transaction or a renewal we would rather inspect current condition than certify something from two years ago.

Generally yes, because most of the work happens on the roof and below grade. What needs coordination is access: roof hatch or stair route, escort or security requirements, and any areas where we need entry to a tenancy to examine the underside of a leak. Interior access is the part worth notifying in advance. Thermal scanning is done after dark, which usually suits an occupied building better than daytime work.
