The overview of the hill, the two community associations, and the university corridor is on the Sahali hub. This page is only the repair decision. Upper Sahali driveways are steeper. Lower Sahali roofs sit closer to campus traffic and to a mix of rentals and family houses. Tell the roofer which one, because a ladder on a steep Upper street is a different morning from a walk-up near McGill.
Where Sahali leaks actually open
Ice at the eave is the shaded-slope pattern. The wildfire plan calls the ground south of downtown a north-facing incline. A roof plane that faces the valley can stay cold on top while heat from the house melts the underside, and water refreezes at the metal edge. A blob of sealant on the shingle above the stain does not fix an eave that is damming. The roofer should look at ventilation, the drip edge, and whether the gutter is sitting high enough to hold ice against the fascia.
Townhouses add a second pattern. The Sahali Cooperative's 60 units share roofs and walls. Water that enters on one slope can print a stain in the next unit. If a strata has rules about contractors, sort that out before someone is standing on a shared ridge. This website does not contact strata councils for you.
Beside Kenna Cartwright, the third pattern is debris. Needles hold moisture in a valley long after a Brocklehurst roof has dried. A repair that swaps three tabs and leaves the valley full will be back. Pair the visit with a gutter clean, or read gutters first and book both.
Stop patching when the deck is the problem
Several seasons of eave leaks, soft plywood, or a shake roof that has been "kept going" are replacement territory. Sahali is outside the Valleyview and Dallas exception, so the design ground snow pressure for new work is the higher Part 28.3 figure. That pressure does not condemn an old roof. A soft deck does. Move to Sahali replacement instead of buying another repair. Metal details for this hill stay on the city metal page, including where sliding snow would hit a stair.
If water is dripping now, call (236) 836-0303 and say Sahali, Upper or Lower, and whether the ceiling is actively wet. You will be connected with a local roofer. There is no Sahali shop run by this site.
