Detailed Roof Inspection & Permanent Repair Quotation
To ensure the fastest response, we recommend calling Crown Roofing at 416-744-7788 to request an emergency crew. Our average dispatch time is 30 to 90 minutes, with full phone support and strict on-site safety protocols.
Upon arrival, our specialised crew will inspect the issue and locate the source of the flat roof leak. Using a proprietary powder concrete solution, they’ll apply a temporary seal that activates upon contact with water—effectively containing the leak and minimising storm damage.
After the temporary fix, our team coordinates with our estimating department to prepare a full inspection report. You'll receive a detailed quotation outlining the required permanent repairs customised to your building. Once approved, we proceed swiftly with long-term restoration.
Emergency Roof Leak Repair in 3 Simple, Reliable Steps
Common Roof Problems That Often Require Emergency Roof Repair Services
Understanding the most frequent causes of roof leaks helps building managers and facility owners take proactive steps before minor issues escalate into costly emergencies. In many cases, only professional emergency leak detection can pinpoint the source of the problem before significant interior damage occurs.
Some of the most common emergency roofing issues we encounter include:
-
Storm or wind damage, often leading to membrane uplift or surface punctures
-
Cracked or blistered membranes on flat roofs
-
Clogged or damaged drainage systems that trap water
-
Rooftop HVAC leaks or penetrations around units
-
Worn or corroded flashing, requiring urgent roof flashing repair
-
Undetected roof rot and mould, especially in older or neglected roofing systems
Whether it’s due to aging materials, deferred maintenance, or commercial roof failure after a storm, recognising these early roofing signs of damage is essential to avoiding major disruptions and unplanned repair costs.


What Happens If You Delay Flat Roof Emergency Repair?
Delaying action during a commercial roofing emergency can lead to far more serious and expensive problems than the initial issue. What starts as a minor leak can quickly escalate, putting your building, operations, and safety at risk. Timely roof damage repair is essential to prevent unexpected disruptions and liability.
Here’s what could happen if repairs are delayed:
-
Slip and fall accidents due to water intrusion on work floors or entryways
-
Damage to machinery, equipment, or inventory, resulting in production delays
-
Interior mould growth and structural weakening, especially in hidden ceiling or wall cavities
-
Insurance claim complications, where delays may reduce coverage or invalidate claims
For commercial and industrial facilities, even a few hours of inaction during a roofing emergency can translate to thousands in operational losses. Acting fast protects not only your property, but your business continuity and legal exposure.

Delaying action during a commercial roofing emergency can result in serious consequences—both structurally and financially.
