What to do when your roof starts leaking in Toronto

A leak during heavy rain is stressful. Start with safety, then gather the details that help a roofing professional investigate.

1. Keep people and belongings safe

Move furniture, electronics and valuables away from water when safe. Catch drips with a container. Keep clear of wet electrical fixtures and seek appropriate professional help.

2. Photograph and note the damage

Take pictures of the indoor stain or wet area. Note when it began, the weather and whether the leak happens during wind, rain or snow.

3. Do not climb onto a wet or icy roof

Roofs are hazardous in poor weather. Avoid DIY repairs at height and call a professional for exterior assessment.

4. The visible stain may not be the leak source

Water can travel along insulation, framing and decking. Common entry points include flashing, skylights, vents, membrane seams, roof drains and valleys.

5. Ask whether repair is appropriate

Not every leak requires a replacement. The right choice depends on system condition, extent of damage and the location of water entry.
