What should you do if the roof is leaking right now?

  1. Put a bucket or a bin under the drip and move furniture, electronics and rugs out of the way.
  2. If water is near a light fixture or an outlet, switch that circuit off at the panel.
  3. Stay off the roof, especially when it is wet or icy. Ontario requires roofers to be protected from falls "when working more than three metres (10 feet) above ground", and that training exists for a reason.[1]
  4. Take photos of the ceiling and anything damaged, for your insurer.
  5. Call us at 647-686-7663. After-hours calls are welcome.

Where do roofs usually leak?

Water shows up on the ceiling, but it almost never gets in right above the stain. It runs along the deck or a rafter first. These are the places we check before we touch anything:

Where roof leaks usually start, and the usual fix
SpotWhat failsUsual fix
ChimneyStep and counter flashing pulls away or the sealant dries outNew step and counter flashing, and a cricket behind a wide chimney
Vents and pipesThe rubber boot around a plumbing stack cracks in the sunNew boot or vent, shingles reset around it
ValleysTwo slopes pour water into one line, which wears fastestIce and water membrane and new valley shingles or metal
SkylightsFlashing kit or seal around the frameReflash, or replace an old unit in the same opening
EavesIce dams push meltwater back under the bottom coursesIce and water protection at the eaves, plus attic venting so the dams stop forming
Open fieldShingles lifted or torn off by windMatching shingles sealed back in

Should you repair the roof or replace it?

A repair makes sense when the damage is in one place and the rest of the roof still has life in it. Replacement makes sense when the problems are everywhere. We will tell you which one we see, and the Province of Ontario suggests you ask any roofer for proof of the damage, such as photos.[1]
