Your Roof Is Leaking Here Is What to Do First
A roof leak does not care about your weekend plans. You hear that drip at 2am and your stomach drops. What now? The wrong move here can turn a small fix into a $10,000 problem. The right move? Stay calm and follow these steps.
Stop the Damage Right Now
The moment you spot water coming in, your job is to limit the spread. Put down towels or buckets to catch drips. Move furniture and electronics away from the wet area. If water is pooling near a light fixture, turn off that circuit right away. Water and electricity are a dangerous mix.
Most GTA homeowners make the mistake of running up to the roof in the rain to check things out. Do not do that. You risk a fall, and wet roofing materials are slippery and fragile. Your first call should be to a licensed roofing contractor who handles emergency roof repairs.

Section 2 — Where Roof Leaks Usually Start
Not every leak means your whole roof needs replacing. In the GTA, the most common leak points are flashing around chimneys, skylights, and vents. Ice dams in winter are another big culprit — they force water under your shingles when temperatures swing above and below zero.
Flat roofs on commercial properties and older Toronto homes have their own leak risks. Membrane cracks and pooling water are the usual suspects. If your flat roof is over 15 years old and you see bubbling or soft spots, that is a red flag.
Eavestrough blockages are also sneaky leak drivers. When gutters fill with debris and overflow, water can work its way under your fascia and into your walls. A quick clean twice a year can prevent thousands in damage.

What a Roof Leak Actually Costs
The size of your repair bill depends on one thing: how fast you acted. A fresh leak caught early can often be fixed for $300 to $800. Wait six months, and you are looking at rotted decking, mould in the attic, and a bill that starts at $3,000.
In the GTA, labour and material costs have gone up sharply since 2023. Getting ahead of repairs pays off. Most roofing contractors in Toronto and Mississauga offer free inspections, so there is no reason to guess what you are dealing with.
If your roof is under 15 years old and damage is localized, repairs are almost always the smarter financial choice. Roofs between 20 and 25 years with widespread issues are usually better replaced — especially with premium materials that now carry 30 to 50 year warranties.
