Why Some Metal Roofs Leak

Metal roofing is extremely durable, but the system must be installed correctly. Leaks usually happen when corners are cut, flashing is rushed, panels are not aligned properly, or water pathways are not respected.

Poor flashing around chimneys, skylights, and valleys
Improper fastening or exposed screw systems
Incorrect panel overlap or weak transitions
Low-quality installation around roof edges
Using the wrong roofing system for Ontario weather

The System Matters

Not all metal roofs are the same. A properly designed interlocking system performs very differently than a basic exposed-fastener roof. The more protected the fastening system is, the better the roof can perform over time.
