Worn Pipe Flashing on a Metal Roof - Here's Why It Matters

Pipe flashings are one of the most overlooked spots on a commercial metal roof. They seal the gap where pipes and vents pass through the roof surface - and when they fail, water finds its way in fast. The tricky part? The damage inside a building can be well underway before anyone notices.

What we're dealing with here is a pipe boot flashing that has cracked, pulled away from the pipe, and separated from the roof panel below it. The sealing material has deteriorated and is no longer creating a watertight barrier. That gap at the base is a direct entry point for water every time it rains.

This is the kind of thing we catch during routine roof inspections. It looks small. It is small. But left alone through a few hard rain events, you're looking at water intrusion into insulation, decking, or interior ceilings - and that turns a simple repair into a much bigger expense.

We use rubberized roof coatings and proper flashing repairs to address these trouble spots before they spiral. A good repair at the flashing point seals the penetration back down tight, bonds to the metal roof surface, and holds up against weather, UV, and thermal movement over time. Done right, it's not a band-aid - it's a lasting fix.

Staying on top of small issues like this is what keeps a commercial roof performing for the long haul. If your building has a metal roof and it's been a while since anyone took a close look at your flashings and penetrations, it's worth getting a second set of eyes on it.
