Flat Roof Repair & Leak Detection – Signs of Damage You Shouldn’t Ignore
At Crown Roofing, we specialise in identifying and resolving the most common roof problems affecting commercial and industrial buildings.
Some of the most frequent issues we encounter include flat roof leaks, membrane damage or punctures, ponding water, and flashing or sealant failures. Storm or wind-related damage can also lead to compromised roofing systems, often going unnoticed until internal signs emerge.
Because leaks don’t always appear directly beneath the source, our team uses infrared scan technology to detect hidden moisture beneath the surface. This non-invasive method of moisture detection in roofs allows us to identify leak sources by tracking leak travel patterns, ensuring no damage is left untreated.
Watch for early roof damage indicators such as:
-
Water pooling for more than 48 hours
-
Cracks, blisters, or bubbling on the roof membrane
-
Rusted or lifted flashing and sealants
-
Water stains or mould on ceilings or walls inside the property
By leveraging the latest in flat roof technology, our team pinpoints the source of the issue with precision and delivers lasting solutions that restore integrity and performance to your roof.
